@@RetroCrisis new edit sounds brilliant

[@miketate3445]

As a gen X guy who was there and an audio professional, that is very close to the correct bad TV sound through RF. I'm impressed.

[@RetroCrisis]

@@miketate3445 your comment made my day. Thanks Mike 🍻

[@markkilborn512]

If you're seeking feedback... and forgive me, game audio is my profession... I'd dial down the pitch wobble/tremolo. It's a bit too much. If you can control the speed of it, make it MUCH slower and reduce the depth of the pitch change so it drifts very slightly out of tune over a longer period of time. It's too noticeable right now. The lowpass filter is a bit too heavy handed. Those old TVs were muffled but not quite that much. I'd raise it a bit, but not too much. It might also be worth pushing the mids a bit, maybe around 600-1000Hz, as a lot of older TV speakers were very mid-forward. This is all based on listening to the video. I'm at work and don't have time to try this on a game right now. But I hope this is useful. This is a very cool project to dig into, excited to try it out!

[@RetroCrisis]

@@markkilborn512 thanks so much. I truly appreciate the feedback. I'll have a tweak tonight using your feedback and hopefully it'll help. Admittedly I've over exaggerated the sound muffledness, more as a proof on concept rather than anything hugely accurate

[@RetroCrisis]

Hopefully the updates are a little better. Added some variety, so hopefully theres something there for everyone - kzbin.info/www/bejne/aKPLkJamfJ1pqtU

[@stevenwarner9156]

Agreed on the tremolo: it sounds like audio from a bad tape recording instead of audio from a soundchip going through mediocre speakers. It doesn't sound natural in this iteration. Edit: The updated presets sound a lot better to me.

[@KimHogeling]

Thanks for the updated version. It's really good!! 🎉❤

[@gersonpagan]

Thank you for this mod and thank you to the comment about the drift/wobble in the pitch; it seems that that LFO is too intense making it sound more like a VHS and not as a TV live. I'd like to add that these old TVs were also resonant in the lower mids; adding a feedback in that frequency or a drive that concentrates in that range of the spectrum could mean that you don't even have to have a filter because the drive would neglect the highs and the lows making it sound boxy. Thanks again for your work.

[@DrxSlump]

I honestly don't remember sound being so muffled even via RF on a late 70s CRT TV

[@RetroCrisis]

@@DrxSlump it's slightly on the exaggerated side for sure. Just a first draft.

[@Kage5868]

filter does cut the bad frequencies but yeah it is way muffled hard to get both

[@RetroCrisis]

I hope this update sounds a bit better - kzbin.info/www/bejne/aKPLkJamfJ1pqtU

[@DrxSlump]

@@RetroCrisis oh yeah, we're kinda getting there now!

[@Zack-pg4dk]

Yeah I still have a 30 year old RCA CRT that gets used everyday and the sound is much closer to the unfiltered version

[@RicochetForce]

Oh my god, combine this with the great shaders being made today and maybe some nostalgic smells and people will absolutely be launched back into another era with this.

[@RetroCrisis]

Haha someone needs to make a cigarette smoke smell plugin too 🤣

[@Tenchigumi]

@@RetroCrisis Ah yeah, the smell of pipe tobacco and yellowing tweed sofas.

[@retropulse03]

*GASP* This is amazing! I didn't know you could just... make something like this! I've used the high-shelf dampen one for ages to curb those high pitches, but this is awesome. Really, really excited to see where you take this.

[@RetroCrisis]

This one was for you bro 🍻 I'm glad I'm not the only one that wanted to get rid of that high area.

[@eyeball226]

I think I'm hearing pitch modulation, which is not a thing that RF input did. This is more of a cheap cassette emulation than the sound of an RF connection to an old TV.

[@RetroCrisis]

Now you mention it, I think you might be right. Like a worn out VHS tape

[@SuperWiiBros08]

Playing B3313 with this can be the perfect experience

[@BerserkerOx]

increible. siempre reviso los filtros de videos, todo lo relacionado a pixelart deberia verse minimo con filtros de videos pero no me habia detenido a escuchar los juegos con un filtro de audio. ahora ya no podre jugar sin el filtro

[@RetroCrisis]

Haha thank you so much. I hope you like the updated versions too kzbin.info/www/bejne/aKPLkJamfJ1pqtU

[@Facelessify1]

Hell yeah, both our eyes and ears being blessed by your work

[@RetroCrisis]

Haha thanks so much dude

[@maximilian3544]

It's pretty insane how much the screechy and tinny mega drive audio gains from some rf muffling. It's mega drive composite video fixing the dithering all over again.

[@slerched]

I love the crisp freshness of cleanly emulated audio. I may be a monster. That said, this DSP is actually pretty awesome and ticks the nostalgia box. I would use it sparingly but I would use it.

[@kealkeal]

Thank you for these plugins, it really takes me back! I'm using the 'composite stereo' plugin and it sounds just like my old Sony Trinitron 27 inch TV!

[@kokkeonglee8005]

Thank you for uploading to make the simulator more perfect

[@niveketihw1897]

I really enjoyed the showcase! I think this is excellent work! Definitely reminds me of the really bad TV I had to play NES on. My favorite from the second vid is RF Clean Mono.

[@JamesDeColling]

I really wanted an arcade style feel, with muddy bass, deep reverb etc, so I ended up buying a guitar effects unit and running it...its brilliant - Zoom G1 Four

[@Lippeth]

Since I can remember, had always plugged the sound component cables of every console I had that used component into a hi-fi home stereo system, and currently use expensive studio reference monitors for emulated games. That said, I love endeavors like this, and sound filters in general! I spend a lot of free time playing game music through Chipsynth MD and SFC and they've got a ton of hardware filter combinations, emulating different versions of consoles.

[@_oBSOLEte_]

Sorry but not for me. I still play my games on the same 40 years old Marantz, in full stereo, with loudness on. Amiga games and dos oldies with MT32s Munt, or those MSU-1 romhacks are sounding too good to go back to mono speakerphone...

[@RetroCrisis]

Oh absolutely, you're doing it right. This filter is more for those having a midlife crisis like myself 🍻

[@_oBSOLEte_]

​@@RetroCrisis I mean, I can see the point of your work. But you should try some VST effects like Audioease Speakerphone or Izotope Trash, they may have convolution presets of some TV speakers of the time.

[@Pjvenom1985]

Nice video man fair play, love the thumbnail too, ole Mario looking slick.🎵🍄🎮☘️

[@brunoguitardreamer]

Excellent initiative! Removing the wobble thing (sounds like VHS) I think it will be 100% pure TV. Thanks for your efforts, awesome work! Edit: I saw your new release. Dude, you rock!

[@user-ly1ko6be9t]

i WAS JUST DREAMING OF SOMETHING LIKE THIS A FEW WEEKS AGO

[@pacmantravel2158]

This is good for Game Boy and Game Gear. Our brand new Magnavox had crystal clear speakers.

[@xendraven]

Well that was disappointing. So wobbly. Plogue made a VST called Chipcrusher. There are some amazing sounding filters that emulates different sorts of speaker found in arcade cabinets, TVs, handhelds and other devices. AI was kind of hoping for something along those lines.

[@RetroCrisis]

I hope the update is less disappointing kzbin.info/www/bejne/aKPLkJamfJ1pqtU

[@jsr734]

In Sega Genesis/Megadrive case we need more options to accurately emulate the diferent hardware revisions disctinctive sound. I wonder if all this mono sound simulations have been compared to the real hardware pluged with RF swithes to different tvs- Not all tvs are equal in how they process RF and composite video signals and that is also true for sound.

[@CyberLabStudio]

There actually has been a lot of work done in this regard and the results of it are actually built into some of the Genesis/Megadrive cores. You might have to search for it but there are threads which talk about this and how best to set the LPF and other Core Options to simulate the different hardware revisions. This is how I've been playing for a while now. For arcade games, I know there's already low-pass audio filter available. Note that I'm not trying to discredit @RetroCrisis's work, just answering the question that this is an area that has room for improvement and is often overlooked but it definitely has received at least some serious attention in the past especially when it came to matching the authenticity of Genesis/Megadrive audio.

[@SmartTube-r2d]

This sounds great! this should be a default addon on retroarch.

[@isomatic]

Im going to use this for sound design and music production.

[@richardhunter9779]

What about component audio? You could entirely reproduce the sound of specific TV set through impulse convolution.

i'm glad i live in france where we had rgb scart on every tv.

What's the name of the game where the song at 11:52 comes from?

[@DavidPereiraLima123]

They didn't sound muffled, but choppier, like on a cheap pocket radio. But to be fair I'm refering to 90's CRTs, not 80's.

[@acdcccccccccc]

Sounds amazing and the update audio is even superb, but does someone have already make it work on steam deck RetroArch via emudeck ? I put the files on the folder but RetroArch seems to not recognize them.

[@yanx007]

But how about a real CRT tv instead? Just kidding! Your idea is AWESOME! It's genius! Thank you!

Awesome filter! Unfortunately, when I tested this on Android, I didn't notice a change.

[@SonicTheFantastic]

Do these filters support Android/ARM64?

[@SonicTheFantastic]

​@@soundspark No. That's why I made the comment.

[@Otavio23BR]

[@RetroCrisis]

Thanks dude. I hope it works well on your computer

[@soundspark]

If only the filter could take feedback from the screen to add that buzzing sound that's affected by the screen contents due to crosstalk.

[@TheVeats]

The games sounded great on crt, this sounds very over exaggeratedly bad. I think people just forgot how amazing the sound actually was. It would be awesome to see a comparison of this next to a decent crt

What gave you the idea to make a filter like this? It’s very impressive but I have to ask why?!?! 😂

[@RetroCrisis]

Good question. I've always found the Mega Drive music to be a bit scratchy, like nails on a chalk board. Just wanted to get rid of those high frequencies, because I definitely don't remember them on my old TV or even my current CRT lol

[@bundjohn]

@@RetroCrisis good point, my CRT is twenty years old which I still use from time to time but I haven’t compared the audio. I should get the mini hooked up at the same time and see how different they sound!

[@RetroCrisis]

@@bundjohn absolutely. What kind of CRT you got?

[@bundjohn]

@@RetroCrisis a small Matsui which has an inbuilt VHS player 😂

[@sophisticated]

How do we do the opposite in retroarch (tweak to improve the clarity and seperation)? I got Diablo on Ps1 running in widescreen and the audio quality is so inferior to the pc version that it breaks immersion. Any ways to tinker with the sound in retroarch beetle hwd core or duckstation? The ps1 version is worth preserving as it has couch coop and the widescreen works without any issues. The controls are not too bad as well.

[@linuxstreamer8910]

thank to diablo 1 psx we have diablo for modern systems/devilutionx

[@sophisticated]

@@linuxstreamer8910 what do you mean? I think DevX is based on the pc version.

[@_oBSOLEte_]

Not in Retroarch, but on linux I use Easyeffects to apply EQ, stereo enhancer, exciter and limiter to the sound. You could find alternatives for it on Windows I guess. I also use an old Emu1616m soudcard that came with its own set of low latency DSPs on Windows.

[@Killa1337]

Mine was no where near that muffled

Sound from retro consoles never had the slight variations in pitch that can be heard in this demo video. If you recorded them to tape and then playback, then yes, of course. That's part of the distortions you can encounter in analog tape media. But this, in my opinion, is a NO NO.

[@TwistedSoul2002]

Hmmm, my TV never sounded like that not even that pos ‘Matsui’ TV we bought from Dixons lol. Do you think you could make something like this? I think he does it in post but it sent me back to 1993 Sega Dome when I heard it! youtu be / NfkO9SKpMOI?feature=shared

[@RichardCraig]

Why is the pitch warbling?!! That was a characteristic of VHS but not of a direct signal from a console. It's immediately distracting and annoying and nothing like what it should sound like. They should rename this the VHS Audio filter, there's no warble in an RF audio signal. What a shame, I've wanted something like this for ages, but my ears can't tolerate that warbling pitch.
