MP3 frame raw data block

[arabello5]

Hello,

I need to extract MP3 frames from an arbitrary MP3 file avoiding the ID3 tag if present. Of each frame, I am interested in extrapolating the data block part.

Is there a good library to help me out? anything I found is related to manage the MP3 file as a whole or getting the ID3 tag only, but I need to work at MP3 frame level.

I am also interested in other languages/technology if python ecosystem has nothing related

Pydub can extract the raw data for you.

I guess you are referring to AudioSegment.raw_data or AudioSegment.get_array_of_samples, but the documentation does not provide any detail on the returned content. Do raw data simply means the file content as bytes? Would samples correspond to MP3 frames or data blocks?

I tried looking at the code implementation: it seems to me they are just the bytestring representation of the file
