In this video I take a live Big Band recording and run it through a dbx decoder then cut a record onto two mediums: plastic and acetate.

Professional record cutting was done with heavy equalization that I'd bet your Montgomery Ward cutter doesn't have. See the Wikipedia article on "RIAA equalization". It was done to compensate for the limitations of the medium and the performance characteristics of the cutting equipment.. The recording would have been done with a response curve that featured low bass and high treble, and playback would have been done with a reverse equalization curve, boosting lows and reducing highs.

really ? no shit ! the recorder he is using is not a pro disc lathe, it was made for voice recordings basically...

Use an equalizer before connecting to the cutter.

The first one I was going to shout "Did you record that album on a drive-thru speaker?" Then I heard the DBX version and WOW it sounds much better. It reminds me of that time in 2008 I tried to set a radio-controlled 'atomic' clock by going outdoors and holding it up to the sky and somebody asked me what I was doing and I said "I'm trying to get RECEPTION!" and they said "What kind of phone company do you have", then I answered "I't's not a phone, it's a clock" to which they replied "How do you get reception on a CLOCK?!" Now the thing to say is "How do you get NOISE REDUCTION on a *dinner plate*?!"

@leeshepherd65129 жыл бұрын
The recording you made is "encoded" in dbx for tape. If you play it back again and set the dbx decoder to tape not disc it will sound much better.

@warrenmacdonald13728 жыл бұрын
Fascinating. I think the rather "muffled" highs and boomy lows in the decoded sample on both acetate and plate were because DBX requires at least a 30 Hz to 15 KHz ( -3dB) frequency response of the recordable media, and a 60 DB s/n ratio, ( which the writer most likely isn't attaining ) so when it compresses the dynamic range of the input signal and accentuates the highs, upon decoding ( expanding ), that dynamic range and high frequency just isn't enough to reproduce the original music, but it does a great job on noise. With dbx, because of the 2:1 companding that occurs, overmodulation of the input signal is an easy thing to do.
@am743437 жыл бұрын
Yes, plus isn't DBX an "encode-decode" process? In other words, you have to "encode" the DBX signal onto the record when you cut it, then "decode" it during playback? Otherwise if it is not correctly done, it will sound like non-Dolby cassette played back with the Dolby button on. (muffled sound.)
@agfamatic919 жыл бұрын
intresting experiment seens like the DPX decoder cuts out a lot of treble though. and about controlling the swarf use a cheap soft painting brush to brush the swarf towards the spindle it seens like most of the amateur record cutting guys use this metod and it seens to work well for them, the profesionals have automatic vaccum systems for dealing with the swarf.
@thomasbrowne98237 жыл бұрын
I was thinking, if you rig up some kind of spindle in the middle, you can loop the swurth on to it when it starts and it should wind around as it spins and keep it out of the way.

I don't know for certain, but theoretically, your home dbx recorder/player despite having a dbx disk button to play them, may not record to the plate, or even a real blank vinyl properly, or as well as a normal dbx disk could sound. What lead me to thinkind this would have to be the input and output for it is labelled as "To tape Rec input" and "as it'sFrom tape Rec output" respectively. I believe that those ports may be optimised for recording and decoding dbx recordings from tape specifically. I may have been completely thrown off by some labels. I haven't even finished watching the video before i posted this.
@jaymartinmobile6 жыл бұрын
The NX-40 can only encode dbx appropriately for cassette tape. It is a dbx type-II encoder. It won't even work as well on reel-to-reel because there is a slight different in the dbx type-I that reel tape uses. dbx encoded records have a little more equalization done to them to help with the frequency curve of a record and the RIAA equalization, so while this does remove surface noise it also severely reduces the highs. You would be better off to just create a 2:1/1:2 compander system using an NE570 chip or similar. At least it wouldn't be fighting the tape equalization curve then.

Fascinating, in the next experiment, can you try to encode the signal in RIAA first, and if you use DBX, you can try "TAPE" also for reproduction, (DBX disc are not encoded the same way as tape, as far i know) Anyway, good job :-)

I've been using a Messiner unit, and for some reason my player either cuts too lightly and the record players I have glide over the grooves, or they are too heavy and I hear mostly just sound from the cutting, when I do get swarf from the PVC blanks it would be slightly overpowering (the cutting sound) over the music that was cut.
