python module to transcode between audio formats using the CLI frontends of the codecs already installed on your system, e.g lame, vorbis-tools etc
supported python versions:
- 2.6
- 2.7
- 3.2
- 3.3
- pypy
As of now audiotranscode can transcode between any of the following formats:
filetype (program used)
- mp3 (lame, ffmpeg)
- ogg (vorbis oggenc/oggdec, ffmpeg)
- aac/m4a (faac, faad)
- flac (flac)
- wav
audiotranscoder [-b BITRATE] <infile> <outfile>
bitrate is specified in kbits/s.
<input> is the path to the file that needs to be transcoded.
<output> is the output path. The file extension of the output determines the output format
audiotranscoder --codecs
shows all installed codecs
Using audiotranscode is as easy as py:
import audiotranscode
at = audiotranscode.AudioTranscode()
at.transcode('path/to/some.mp3','output/path.ogg')
you can also set the bitrate of the output stream, like so:
at.transcode('path/to/some.aac','output/path.mp3',bitrate=128)
You can also get the encoded data on the fly for live transcoding:
for data in at.transcode_stream('path/to/some.flac','mp3'):
# do something with chuck of data
# e.g. sendDataToClient(data)
If you need to know which formats can be transcoded:
at = audiotranscode = AudioTranscode()
at.available_encoder_formats() #returns list like ['mp3','ogg', ...]
at.available_decoder_formats() #returns list like ['mp3','ogg', ...]
As of now, i have only tested 16bit, 44100Hz, 2 channel audio, since it is the most used, other formats might or might not work.
But feel free fork this repo and to add stuff!
