It would be nice to have an audio upscaler AI model within VEAI and or even a standalone audio upscaler app for music and old recordings. Sometimes old videos have low quality audio or the original audio wasnt captured correctly or formatted correctly and sounds off. This would fix that.

Best of luck! I really love what I have been able to get UVR to do, and it’s free!

[image] ForSerious: The biggest issue to this would be getting the audio back into Dolby and DTS formats. Conversion to PCM would more than suffice for me. Thing is, though, ‘upscaling’ audio is a lot harder than doing so for video. The latter consists of thousands of pixels, all offered par…

What does upscaling audio mean to you? I’ve been using Stereo Tool to fill in the lost high frequencies in compressed audio and even in 80s recordings that didn’t have anything above 15kHz. I think it’s a form of interpolation, but maybe it’s called something else. Anyway, making an AI to do the sam…

[image] ForSerious: I think it’s a form of interpolation, but maybe it’s called something else. Anyway, making an AI to do the same kind of thing would be ultra easy—so much so that it’s probably already been done. If so, I will go look for it. :slight_smile: Haven’t really seen it, though, y…

Good sound can make a video seem as much as 2X better on a subjective basis with human subjects.

Here is just a high level summary of the research from Human Factors and Perceptual Cognitive Science studies over several decades. It is my opinion irrefutable. If you have any doubts a simple way to test this compare how you feel when you have a crystal clear, hear the pin drop, telephone convers…

I never have the audio playing when I’m evaluating how well the AI enhancement model did. I agree that better audio quality can be key, but who knows if Topaz will go into that.

The fact that this idea has 29 votes, one of the higher numbers I have seen for a user proposal, and after about 1335 days nothing has been done, no clear justification for inaction, is not a good sign. Voice of the Customer (VOC) matters. Not listening to the VOC results in bad karma.

Topaz Labs LLC should endeavor to improve the sound quality of the video that it visually enhances and upscales. Companies that ignore audio improvements or test only isolated video metrics risk missing critical opportunities for perceptual optimization and competitive advantage.

[image] ForSerious: ffmpeg Thanks for the tip on ffmpeg, ForSerious. My question is more mundane. If I burn a DVD with the MP4 should I think of recoding the sound track for a different codec so it will play on the now mostly forgotten DVD player that some relatives of mine still have. [I fo…

Hello redman.41.2077,

I notice your profile indicated No GPU! How do you do it? I mean with video. Is it down to the three web apps. It seems OK for one or two hours of upscaling. But a collecton of VHS and DVD’s from the 1980’s sounds like it would be costly to convert.

At least one person has considered buying a dead piece of software:
