WAV recording quality question #185

Open MartinBarker opened 2 years ago

MartinBarker commented 2 years ago

Hello, I was wondering if it would be possible to get high quality wav file recordings using waveform-playlist? I've tried adding waveform-playlist to a desktop electron application here: https://github.com/MartinBarker/waveform-playlist-electron.git

And have tried recording from my turntable playing a vinyl record, which I download the wav snippet, but it comes out as a 16bit, 1411kbps, 44100 Hz 2 Channel wav file, which sounds very muddled and low quality.

I was wondering if it was possible to get higher quality wav audio recordings that could rival audacity output? Such as a 32 bit 2822kpbs, 44100 hz 2 channel audio file?

If you're interested I've attached a zip file with my waveform-playlist and audacity recordings from the same microphone input

I think this should be possible, I'll have to look into upgrading the recording code that has been in the project for quite a while now to make sure it works properly.

Thanks, I've been looking into it too and managed to use opus-recorder to record a high quality wav file in my browser: https://github.com/MartinBarker/opus-recorder

[edit] made a smaller version of the repo with only the bare essential code needed to record HQ wav in a web browser, tested in chrome https://github.com/MartinBarker/opus-recorder-min

The saved wav file is 32 bit, 2822 kbps, 44100 Hz, 2 Channels. My repo just records and outputs the audio file, no waveform visualization, but its sort of a proof of concept to try and achieve a high level of audio quality from a web interface.

I can run waveform-playlist, and record high quality wav with opus-recorder, now I'm trying to figure out how to connect the opus-recorder audio recording with waveform-playlist
