Your silent record has just sparked a memory. Many moons ago I was in a pub which had an old fashioned jukebox that played records. I noticed that music would be playing and then there would be long spurts of silence, then without anyone returning to the jukebox, music would start playing again. The landlord informed me that there was actually a silent record in the jukebox, and the old farts in the pub who wanted some quiet time would actually put money in the jukebox and select the silent record. And by all accounts, it was quite popular. Maybe this wasn't as rare as I thought, but I had never encountered this before.

[@crispy_otter]

I remember buildng a de-scratcher back in the 70's from a circuit in - I think - ETI, may have been EE. It detected the scratch and replaced it with a short period of silence. It wasn't very good!!! Luckily, there is now a brilliant way to eliminate the noise, distortion, lack of dynamic range, channel imbalance and expense of vinyl. It's called the Compact Disc 😊😊

[@AudioHead809]

I thought one of the only benefits of vinyl was the possibility for more dynamic range. At least in the modern age.

[@aKuBiKu]

@@AudioHead809 Yeah, in most cases. You have to be careful while buying CDs, most of them sound like crap because of awful mastering. The good ones though? The good ones are exceptionally good. Better than any other (popular) physical format out there.

[@IntegerOfDoom]

Exactly... The whole point of vinyl these days is enjoying fumbling with the physical media and listening to all its imperfections.

[@crispy_otter]

@@AudioHead809 the reality is that the dynamic range starts out as about half of a CD. Each time the disc is played, it reduces as the grooves wear. Even modern vinyl and production is limited - the groove width is limited, even with the RIAA encoding. It's the main reason all the classical music buffs flocked to CD when they first appeared (even if the players were a bit harsh back then! They have improved massivly over the years) - it was the first time that classical music could be heard as nature ntended!!!

[@williamjones4483]

So sorry to inform you that the various manufacturers are killing off CD's & DVD's while vinyl is making a comeback.

[@nathanmoak1515]

several years ago, i was digitizing my noisy records and used a computer program "audio cleaning lab" from germany. it took me several hours to get the hang of it, but it did a reasonable job of reducing noise. i preceeded to digitize hundreds of vinyl records and cassettes. the program set me back $40 and was worth it as many albums i had were not available on cd.

[@US_Joe]

Even Radio Shack had such home audio accessories, which in my opinion, were just another gadget to display on your rack. However, there WAS a professional studio device called a TNE (Transient Noise Eliminator). I have 2 of these in my collection. They are purely analog, and you can monitor and hear the Difference of what sound is being eliminated. They are rare to say the least. Good vid !

[@Starlight-AG]

Hello UsJoe.... you beat me to the comment. Back in the day (70's), I came across the plans for a Transient Noise Eliminator like you mentioned. I modified it to work at line level instead of between the cartridge and the Phono input. I built this device as I was at the end of what I could tolerate in records. Unlike the one tested here, mine worked flawlessly and completely eliminated any trace of the click/pop as if it never existed, like magic. You could adjust the sensitivity to suit the condition of the record. This device is a boondoggle. It clearly does not work and for the price, they are selling people a bill of goods for high prices just like with the so-called High End Audio equipment today. Back in our day, pretty much ALL amps from ALL name brand manufacturers could deliver the quality and performance that today's equipment CANNOT do unless you are prepared to pay thousands. Even then you need sub woofers as the amps are not capable today. Back then it was standard performance. That being said, why anyone would purposely want to use vinyl records as a source is beyond me. I grew up with that technology and I can tell you there is NOTHING better or even good about it. Those who claim 'it sounds better, more warm etc' are delusional. There is absolutely NO science to support this. I do appreciate this video as it just shows so called 'Audiophiles' are being conned. That's my rant for today. :-)

[@US_Joe]

@@Starlight-AG Thanx for response. The units I have employ a headphone jack which monitors JUST the sounds being eliminated with a special switch. All you hear are low rumbles and high crackles and pops. I would adjust the gain until I just barely started to discern the audio signal source. I have remastered many of my reel 2 reel recordings with this method satisfactorily. As for the digital to analog debate, let's save it for a another time, as I am one of the proponents of raw analog tube amps etc. which I believe DOES create a sense of warmth and depth as opposed to digital. Regards - US Joe

[@xenuno]

@@Starlight-AG "Warm" is just the result of a physical object with mass and inertia being moved around in a magnetic field. Since there is limits to how fast it can be accelerated/decelerated plus a mechanical range limit, the actual analog signal can be warmer (as in frequency blending) over say, a digital encoding. It's the audio equivalent of say a soft focus in photography with Photoshop acting as RIAA post amplification. I can't personally say though that on decently produced samples of each (LP vs CD), that this warmth was detectable. An audiophile would point out that my amp transformer is only copper wound, not silver .. thus I won't hear any difference

I collected LP's from the early 1960's up to about 1983 when CD's became available. At the later date I had an SAE 5000 INRS (Impulse Noise Reduction System) which I used for LP playback. That was a clearly superior product to the one demoed in this video. It didn't just reduce the clicks and pops, it actually cut out a few milliseconds of the feed containing the click and substituted an equal length snippet of the audio immediately prior to the cut. It also had an "Inverse" function that allowed listening to the audio that was being removed. One could select inverse and then adjust the sensitivity to just below the level where musical content was being affected. It is a fantasy to suggest that only "old" LP's require noise reduction to be listenable. A brand new out of the wrapper vinyl record will have not just the ever present "hiss" of surface noise but outright clicks, likely due to to dust particles. And yes, there are ways of reducing but not eliminating (short of a clean room) dust clicks. Within a few years of halting LP purchases software noise reduction apps became available. The first one I used was DART (Digital Audio Reconstruction Technology). These types of apps are not for real time use. Currently, I use the NR tools in Magix Sound Forge. iZotope also has a similar suite of NR tools. Years ago I transcribed all 600 of my LP's to CD using such tools. I still use them for transcribing a collection of about 5,000 78 RPM records I inherited from my father. Although the software tools can make a significant improvement in a single automated pass the best results still require manual intervention. It can easily take an hour or so to achieve the best results on a 3.5 minute 78 side. Here is a link to a 78 from 1923 that was restored using Sound Forge: soundcloud.com/synoptic-designs-studio/cinderella-blues-herb-wiedoefts-cinderella-rooftop-orchestra-1923

[@Syncopator]

The reason the bass goes away with the rumble filter is that it’s likely just a high pass filter. Which also means that cranking up the bass to compensate will just crank the rumble back up.

[@graealex]

It's as if one just can't remove noise in the analog domain...like an intrinsic property of signals. Imagine if you could just "remove" noise from RF transmissions...

That said, back when I had a nice rig and played my first real and expensive audiophile record of a jazz setting I was amazed at the total background silence and stage presence. Now I just listen on anything and enjoy the actual music.

[@kaitlyn__L]

For me it’s tape hiss, growing up with a basic walkman (but also hearing my father’s fancy hifi). Same auditory phenomenon though. He definitely played some vinyl on it, and a lot of my tapes were dubs he’d made from vinyl, tape, or CD, but he kept his records clean and so the vinyl dubs didn’t feature many pops if at all.

I agree Chris. Often we get caught up in admiring the media or technology and we forget the fact that it's purpose is to convey the message or song. You can go to a lot of expense and trouble to make your vinyl sound as silent as possible then find you can hear the hiss from the master tapes. Every media isn't perfect, and with my tinnitus nor is my hearing these days (not to mention my floaters), so I try to get lost in the music and cut my tech some slack. Like the pops and clicks for you, my brain thankfully filters the majority of my tinnitus out too. Enjoy your music Chris LJ.

[@shellac4682]

Excellent review and demonstrates quite effectively why this device is not worth the money. I suspect the rumble filter is similar to a low frequency filter, a device that was common on amplifiers a long time ago. My Sansui AU-7500 [vintage 1974] has low and high filters that I use sparingly, most often for 78's. The low filter is perfect for rumbly Perfects and Pathes from the late '20's, and occasional records that were recorded with a hum from the mains.

[@ChristopheBaudet]

Your first test with the TriMicron record absolutely demonstrated a difference with the decrackle performance. The crackles were much more muffled, though still very present, almost like there was just a high pass filter being applied at the moment where a crackle was detected. I'm not suggesting this justifies the product, but there is a clear audible difference that some listeners may prefer. I wonder if this only applies to listeners who still have good high frequency hearing (possibly why you couldn't hear it, sorry?!) and are listening on reasonably high fidelity equipment.

[@lv_woodturner3899]

I have an SAE 5000 Impulse Noise Reduction unit sitting to my right. This was purchased in the early 80's. It reduces the crackles or click/pops/scratches. A slider on the front to set the sensitivity and buttons to remove the crackles or select only the crackles so you can hear the noises being removed. Setting the sensitivity too high causes some of the music to be discarded. A Supertramp album, Crime of the Century had a bad scratch on the track School. This unit was able to remove most of the scratch. I later purchased a Direct to Disc version of the album which did not have any scratches. Back in the day SAE made good products. Dave.

I was watching a video series by Amoeba Music called, "What's in my bag?" The basic premise is that they follow a music celebrity around their LA shop and get them to talk about their favourite records, and pick out a few to purchase. So, I was watching this video, featuring former Skid Row front man Sebastian Bach. Seb mentioned that his house in Jersey was wrecked in a hurricane and his record collection, which included first pressings he purchased as a kid, was ruined. Seb claimed that he was able to cover the albums in glue, and after the glue dried, was able to peel it off, and it made quite a few of the knackered records sound like new. Not the type of thing that I would try with anything I really cared about, but I feel like a test of this method with an unimportant record could make a great Tech Moan video.

While watching a very old interview with super studio engineer Bob Power I was amazed to discover that during the making of Low End Theory they used something just like this (but entirely analogue) to remove pops/noise from crackly vinyl samples. I still find it pretty amazing that existed back in the 80s/90s as Bob said the unit was some funky old hifi piece that had been floating around a while 😮. Not sure I see a lot of value in a device that has to digitise it first as there have been effective audio plugins for that at least 15 years probably more like 20+ (eg waves x-click/ x-crackle and izotope rx). The lack of phono preamp also seems silly.

[@BobWiersema]

Yeah the analog stuff has been around a long time. I have a early 80's Yamaha R-900 that has Subsonic & High filters. It does a really nice job on cleaning up not so good vinyl. Sadly the Yamaha has been sitting on my bench for two weeks with a power amp issue.

[@nickwallette6201]

There are a few things like this around. Puffin DSP Phono Preamp from Parks Audio is pretty darn good too, but some of them are really expensive. People who are audio nuts tend to spend a lot of money on things like this. This Pro-ject one, VNRS, without the decrackle, is basically a filter that blocks the low end, like a subsonic filter. If you increase the bass to compensate for it, you'd likely bring the rumble back.

[@keithwiebe1787]

It's way cheaper to buy a 5 dollar cd and be done with it.

[@UnitSe7en]

Seems like a bit more than just a bandpass filter. Certainly that's a key method of it's operation, but if that's all it was it wouldn't need to digitize the stream. It's definitely doing some other mathematical processing to the signal (the effectiveness of this is left to your own opinion) - You can hear it, too. Not just a bandpass filter.

[@MrMurUK]

@@UnitSe7en If you used computer based NR they profile the noise alone and then the plugin deducts it from the audio, but the bass always seems somewhat affected too, especially if you're aggressive with the NR settings. I presume this is doing something similar but with a pre-profiled noise. It would be way cheaper to get a computer audio interface and use plugins, at least for the rumble reduction.

[@kaitlyn__L]

@@UnitSe7en digital EQ means higher profit margins for Pro-Ject. Relatively cheap converters (ie not bottom of the barrel) match or out-perform the characteristics listed. It keeps the component cost and signal chain small too. It’s possible there’s pre-profiled noise filtration like the other person said, but I think a lot of it is just carefully chosen notch filters. You can hear the crackles which are higher or lower pitch make it through, it only blocks an average-pitched pop.

I still have a SAE 5000 "Impulse Noise Reduction System" purchased in the 1970's. It works on an entirely different principle (?), storing a fraction of a second of audio, and substituting that in place of sound with a detected pop. I think my results are slightly better than your tests, although I couldn't do tests like yours in the 1970's. I purchased the SAE after seeing a live demonstration in a HiFi store (remember those?) where the demonstrator took a 33RPM vinyl disk, and using a ruler and a razor blade, made a deep groove from edge to opposite edge. When played without the SAE (or bypassed), as you might expect, we heard a big pop twice each revolution. With the SAE in the signal path, the pop was totally removed, amazing to hear and quite impressive. But after trying out my purchase in the real world and getting less rewarding results, I came to the conclusion that if you have records with a large groove from a razor blade, this was the perfect solution. Unfortunately, I have never owned any records like that, so the SAE is a much less remarkable fix. Still, on occasion, when reviving records from garage sale sources, it has been useful.

I bought my Sweet Vinyl SC-1 Mini Sugar Cube when it was an Indigo fundraiser in 2020, and love it to this day. It is an indispensable part of my stereo kit. RCM's can get only so much dust and dirt out of the record grooves ...it doesn't matter how much or how thoroughly you clean your records. While I do love vinyl - I have been an audiophile since I started collecting in the 1960s, but the pops, clicks, and surface noise were always bothersome to my ears. No longer. Additionally, I have the same TriMicron Beethoven LP you tested in the video. Even after a thorough RCM clean the pops and clicks are reduced but still annoying. Set the SC-1 Mini to minimum and it's dead quiet, just music.

As a professional audio engineer, pops and clicks are hard enough to deal with in post-production with proper full track analysis and an empty section of track to compare to create the baseline for the Pop/click filter. Doing it on the fly has never really been that feasible. Typically in live audio we just end up using a compressor, sometimes with a narrow band eq to try to contain them So far as the noise reduction goes, It sounds like it's a fancy low bypass filter. Effective, but it will affect unintended low end sounds as well. There's no such thing as magic!

Might be interesting to see how well this unit's pop/crackle processing compares with an old Burwen Research DNF-1201A, which I believe was also sold under the KLH brand as the TNE-7000. Those old units processed audio signals entirely in the analog domain, and, as I recall (disclaimer: it's been a long time), did a very respectable job of reducing transient noise events like ticks and pops.

[@BonnibelLecter]

I love that as soon as I saw the title I went, "He's gonna try it on that TriMicron record." That bad boy is infamous on this channel.

[@fritzarmstrong8232]

I highly recommend the KLH Burwen Research TNE 7000A for this noise reduction application. My father acquired one of these units in the early 80s. I learned to use it properly when I was around 10 yrs old, on my noisy Beatles records from the 60s. I inherited it when he passed. It utilizes fully manual control of the analog NR using two knobs, for threshold and sensitivity. There are two indicator LEDs for high frequency calibration and Transient Noise Elimination. The trick is adjusting it for maximum NR vs. adding distortion. You have to just trust your ears. Every record is different, so this is not a set-and-forget type of box. It seems to do it's best work when you set the knobs to zero at the header of the disc- where there is no program, increase the sensitivity knob to the point that the calibration LED partially dims, and once the program starts, increase the threshold knob until it sounds bad (distortion)- then back it off a bit. This usually produces fantastic results, with an absolute minimum coloration of any kind to the program. It does not deal with reducing rumble at all, though. But, that can usually be taken care of by a rumble filter. These 2 rack-space units can still be had for cheap. I recommended to a friend- thinking yeah, good luck finding one these days... He purchased one from eBay the same day. They also come up on Reverb and other resale sites. I think he paid $70 USD. He's also thrilled with it! The best part besides it doing exactly the thing it's supposed to do, is seeing the TNE LED light up like crazy- and hearing NO crackles, pops or fizzes... Knowing it works

[@siberx4]

I found the rumble reduction immediately noticeable on the first record, so at least that part is definitely effective. For the de-crackle, to my ears it didn't _eliminate_ any crackles, but did take the harsh high-frequency edge off them; depending on your hearing and age this might not be as noticeable, and it did require being cranked up fairly high for it to be a meaningful difference. It would be interesting to zoom way in on your recorded audio track wherever you have a big spike and see how the _shape_ of each impulse differs before/after turning on de-crackle. Even if the "peak" is just as high, if it's got a more gradual roll-off in the signal after the spike, it will eliminate a lot of the high frequencies in the click which will make it less audible over other audio. That being said, I felt that both features (even when maxed) had a very minimal negative effect on the sound quality of the "intended" audio coming through, so Pro-ject have done a great job on that front; almost all "noise reduction" systems I've tried to listen to before end up making the actual audio muddied and unpleasant. It's not the strongest effect, but I felt both settings were a net benefit (at least to me). Certainly no scam, and for the right kind of listener with the right kind of vinyl collection, this would be a pretty useful device.

[@johngaltline9933]

Was thinking it would be nice to see a side by side of the same section of audio with and without the device. I'd just record it in to the computer without, then play it back from the computer through the device, so you can see how the thing changes the exact same crackles.

[@Zobeid]

DBX produced a lot of noise reduction boxes. Many of them were "double ended" systems that required both DBX encoding and decoding. I remember having one of those boxes long ago and use it to make super-clean recordings to cassettes. But of course, then I could only play those cassettes back through the same box. It was fine for my home hi-fi system, but I couldn't use those cassettes in a car, walkman, or trade them with other folks. DBX also produced "single end" boxes that you could feed any noisy, non-encoded signal into for cleanup. I have one of those now, called a SNR-1, and it has some value when playing back most ordinary LP records.

Almost like a crackling, cozy fire in the background of my unconscious listening mind. As long as they're not ridiculously overbearing on the sound, I not only don't mind them; I expect them to be there, as part of what vinyl just is. So much so, that, when my son and I recorded several records onto 10-inch reel to reel tapes, we included the needle drops and record run-outs.

Back in the days when I played a lot of vinyl records I found that if there was a pop or crack, it was usually a grain of some sort which was stuck in the groove and wouldn't come out by brushing. But using a magnifying glass and a needle it wasn't hard to remove if you were careful, and normally this would completely get rid of the noise. By the way, how many grooves on average are there on a normal long playing record? Answer: Two! One on each side. (Just a little joke you can sometimes catch people out with).

Some of them did make an improvement, but they were all very subtle and to my mind it was too small an improvement for the cost invoved. I found that if you listened to a record that you enjoyed enough, you just stopped noticing the crackle and it became part of the experience. Records with scratches too loud to ignore wouldn't be helped by technology anyway, and sometimes the drop-out when it removed the scratch was more intrusive than the actual scratch.

Interesting though that if this device with its fancy DSP tried to apply that algorithm - cutting the audio completely around the scratch - you’d probably get better results; all it needs to do is buffer up a bit of audio and then throw out transient peaks.

I was somewhat aware of those devices, but I wasn't into LPs at the time, so I never tried them. I know they had mixed reviews. Today the SugarCube works like magic for me, though.

Another great review, Matt, thanks a lot for all the work you put into your videos! Re the 'silent record demo': Maybe it would have been a good idea to record a 1-to-2-minute passage without any processing, loop that initial recording in software (as 'equal playing field' for the different intensity stages), feed the entire track back into the NRS, and re-record the end result for the comparison of the differernt processing settings. BTW, what I'd REALLY like to have, is a software that does not try to 'fix' scratches automatically, but only assists me in finding them and lets me correct them manually (and separately per channel).

I’ve heard one of the SweetVinyl products at an audio show. It worked incredibly well. I was very impressed.

Some Soviet-produced amplifiers had a special one extra regime at their source knob to play vinyl with noice reduction. So, the same idea has already been realized in analogue way

Hi. Can you name some of those ? Thanks.

[@duskonanyavarld1786]

Compact cassette also had analogue noice reduction I think but it had a coder and a decoder. This and maybe also the Soviet amp will work without a coder.

@@duskonanyavarld1786Vinyls have a standard noise reduction, it’s one of the things the phono preamp does.

@@xluumu Thanks, now I know.

@@duskonanyavarld1786 Compact cassette utilized several two-pass noise reduction circuits. There are Dolby a, b, or c, as well as DBX encode/decode, and then there's single-ended DNR (Dynamic Noise Reduction). and the work by Richard Burwen.
