RVC does live voice changing with a little latency: https://github.com/RVC-Project/Retrieval-based-Voice-Convers...
The product isn't exactly spectacular, but most of the works seems to have bene done. Just needs someone to go over the UI and make it less unstable, really.

Project mention: Are there any libraries that I can use or any way to make such audio waveforms? I looked into a library called "react-native-audiowaveform" but it's not being maintained anymore and doesn't work for newer versions of RN | /r/reactnative | 2023-05-21https://github.com/dmrschmidt/DSWaveformImage for iOS
you could always cut up the video into segments A,B,C,D,E using like ffmpeg -ss 00:00:00 -t 00:10:00 -i input -c copy A.ext (where A is the first 10 minutes of video) and then recombine with https://trac.ffmpeg.org/wiki/Concatenate, might take a while though and some basic math. maybe you could do something programatically with chromaprint by identifying the repeating audio segments? that's just an idea since that's what this jellyfin plugin does to identify repeated segments of shows in the form of opening credits.

It is far easier to use a non-Windows operating system and simply direct the IQ data into the application you want, or use a better app which can take data directly from the RSPdx. However, in an RTL-SDR book, I saw a reference to VB-Cable, which is a separate software from VAC. Pipewire is another tool, definitely open-source and free, which should work.
I have a little hobby project where I record an FM radio music station using a SDR and then remove all the non-music portions for offline listening. I like the music selections the DJs pick, but I prefer not to listen to the DJ commentary and the advertisements.
I evaluated three methods of recording: analog capture from a standalone FM receiver, using this nrsc5 library to record the "HD" radio stream, and using an AirSpy SDR with this library: https://github.com/jj1bdx/airspy-fmradion
Recording the "HD" (what a misnomer) radio was nice in that there was no hiss or multipath effects, but in comparison to the other methods the digital compression artifacts became impossible to un-hear. It seems to top out at about 96 kbps
The airspy-fmradion library has some nice stuff in it to address multipath, resulting in the best audio quality of the three methods I tested.
I use https://github.com/ina-foss/inaSpeechSegmenter to identify which segments of the recordings are speech vs. music.
Project mention: Zimtohrli: A New Psychoacoustic Perceptual Metric for Audio Compression | news.ycombinator.com | 2024-05-08PEAQ/PESQ and visqol is worth trying for that. In principle they operate as you suggest. I keep a short overview of audio quality methods/tools here: https://github.com/jonnor/machinehearing/blob/master/audio-q...
I am currently working on a project called SoundSage - LLM Audio Processing, which is hosted on GitHub. The project is aimed at developing a system for audio processing using various tools and techniques. You can find the repository here: SoundSage - LLM Audio Processing
