How to change volume of stem files while playing using python

Asked 2022-Feb-22 at 13:00

I'm attempting to write a python project that plays multiple parts of a song at the same time.

For background information, a song is split into "stems", and then each stem is played simultaneously to recreate the full song. What I am trying to achieve is using potentiometers to control the volume of each stem, so that the user can mix songs differently. For a product relation, the StemPlayer from Kanye West is what I am trying to achieve.

I can change the volume of the overlayed song at the end, but what I want to do is change the volume of each stem using a potentiometer while the song is playing. Is this even possible using pyDub? Below is the code I have right now.

Answered 2022-Feb-22 at 13:00

Solved this question, I ended up using pyaudio instead of pydub. With pyaudio, I was able to define a custom stream_callback function. Within this callback function, I multiply each stem by a modifier, then add each stem to one audio output.

When you upload the recorded Blob you set the type to 'audio/mp3'. But unless you use a custom library which patches the MediaRecorder the mimeType of the recording will be whatever the browser likes best.

As of now it's 'audio/opus' in Firefox and 'audio/webm' in Chrome.

If you define your Blob like this it should work.

According to the source code it is searching for a flac without exe extension that will not work in Windows. If that fails it looks for a file with a specific name (flac-win32.exe) in module folder.

You can either try to remove the extension of the file in the System32 folder or put the file in the module folder.

I believe it's slow because when you loop over x, you repeat operations (the loop over y) which could be computed before the loop over x, then assembled.

Your call to os.path.basename("data/what.wav") returns 'what.wav'

You then split that using "-" as the splitter, which returns ['what.wav'], a list of one element.

But you then try to reference the third element of the list with [2], which throws an exception.

Setting rms relative to another audio file using Pydub

Asked 2021-Nov-05 at 23:42

I'm trying to set the rms level of an AudioSegment in Pydub relative to another file, before overlaying the two. The method I'm trying to use involves setting the relative rms of the first file to be +4 dB more intense than the second- I know rms isn't modifiable, but dBFS is. I'm trying to modify it with apply_gain(), but printing the rms and the dBFS doesn't show any differences before and after calling that method.

At the moment, my code looks something like:

Answered 2021-Nov-05 at 23:42

I understand that apply_gain returns a modified copy of the audio segment.

Vulnerabilities

No vulnerabilities reported

Install pydub

Open a WAV file. ... or an ogg, or flv, or anything else ffmpeg supports. Make the beginning louder and the end quieter. Concatenate audio (add one file to the end of another). How long is it?. Crossfade (again, beginning and end are not modified). Fade (note that you can chain operations because everything returns an AudioSegment). Save the results (again whatever ffmpeg supports). Save the results with tags (metadata). You can pass an optional bitrate argument to export using any syntax ffmpeg supports. Any further arguments supported by ffmpeg can be passed as a list in a 'parameters' argument, with switch first, argument second. Note that no validation takes place on these parameters, and you may be limited by what your particular build of ffmpeg/avlib supports.
Installing pydub is easy, but don't forget to install ffmpeg/avlib (the next section in this doc). Or install the latest dev version from github (or replace @master with a release version like @v0.12.0)….
