M4A support #20

Closed bohning closed 10 months ago

bohning commented 1 year ago

m4a audio format seems to be supported as input, but not as output, contrary to what is stated in the readme ("output_format: (Optional) Format to encode output files, any common format (WAV, MP3, FLAC, M4A, etc.). Default: WAV").

When I try to output to m4a, I get Unknown format: 'M4A' (which stems from the soundfile module, which in turn relies on the libsndfile module). The libsndfile module already has an issue for the m4a support: https://github.com/libsndfile/libsndfile/issues/389.

beveradb commented 1 year ago

Wow, I totally missed this! Sorry about that. I'll change it to use pydub for writing audio files later this week, which should make it work for anything ffmpeg supports (definitely includes M4A).

In the meantime you could output to WAV or FLAC then run ffmpeg -i <audio-separator output file> output.m4a

bohning commented 1 year ago

Thanks a lot for taking the time to respond and address the issue. I can work with mp3 for the time being, but I am looking forward to m4a support!

beveradb commented 10 months ago

Hey @bohning, so sorry for the super slow response on this, day job and life got the better of me and I didn't end up getting back to working on audio-separator for a while.

Anyway, I've just made a bunch of improvements to it and I believe the latest version of audio-separator (version 0.9.3 or greater) should support every format ffmpeg supports now (including M4A, which I specifically tested)

Hopefully that works for you, but if you have any issues feel free to re-open!

bohning commented 10 months ago

Thanks so much, I will look into it these days. Happy holidays!

bohning commented 6 months ago

I finally got around testing this and it fails for my m4a. soundfile.py doesn't seem to like the format: soundfile.LibsndfileError: Error opening '/var/folders/nq/_mxrjgvd73d0_h92kqhcf3y80000gp/T/tmpcvlf8d3p/audio.m4a': Format not recognised. I know this seems to be a soundfile/Libsndfile issue, but since you wrote that you explicitly tested m4a, maybe you know what could be wrong.

In any case, thanks a lot!

P.S. I opened an issue at the soundfile repository: https://github.com/bastibe/python-soundfile/issues/431

beveradb commented 5 months ago

Please could you send me the file to test with @bohning, or share the output from ffprobe for that file to confirm what format it is?

I just tested again with an M4A file I created using ffmpeg -i test.flac test.m4a and it worked fine:

oh, I realize that it's outputting as M4A which you're trying to do, not processing M4A input files, apologies for the previous message probably not being relevant.

However, the same kinda still goes - I'd like to see more detail about how you're running audio-separator (full command, debug log output etc.) and a test input file, as outputting as M4A "works for me":

bohning commented 5 months ago

Actually I want both - process an m4a input file and write the two separate tracks as m4a output files.

I'm using it in my Python program, installed via pipenv install.

Here's the relevant code snippet (ext = "m4a" in this case):

from audio_separator.separator import Separator
...
separator = Separator(output_format=ext.upper(), output_dir=ctx.locations.temp_path())
separator.load_model(model_filename="UVR-MDX-NET-Inst_HQ_3.onnx")
vocals_file, instrumental_file = separator.separate(audio)

I do get tons of output, which ends with
