Hi,
Is there a python based tool to cut mp3 and wav file at a start and end
time? I'm looking for a python script that can output a new wav or mp3
file based on star and endpoint.
Thank you
there is a wave module
['Chunk', 'Error', 'WAVE_FORMAT_PCM', 'Wave_read', 'Wave_write',
'__all__', '__builtin__', '__builtins__', '__doc__', '__file__',
'__name__', '_array_fmts', 'big_endian', 'open', 'openfp', 'struct']['__del__', '__doc__', '__init__', '__module__', '_compname',
'_comptype', '_convert', '_data_chunk', '_data_seek_needed', '_file',
'_fmt_chunk_read', '_framerate', '_framesize', '_i_opened_the_file',
'_nchannels', '_nframes', '_read_fmt_chunk', '_sampwidth', '_soundpos',
'close', 'getcompname', 'getcomptype', 'getfp', 'getframerate',
'getmark', 'getmarkers', 'getnchannels', 'getnframes', 'getparams',
'getsampwidth', 'initfp', 'readframes', 'rewind', 'setpos', 'tell']
and so on, this is what google gave me

I did some wave ploting with matplotlib module, so I think
it's feasible to cut and write wave files too
as for mp3, I don't know of any modules
I think mainly because of license issue
you could decode mp3 to wav and process whatever you want to process
but to encode them back into mp3 is a problem
maybe you could use lame or bladeenc as a command line tool
or use ogg instead

there are de/encoders freely available
this may also be interessting to you
