[question] split file according to cue sheet #261

Open fenugrec opened 1 year ago

fenugrec commented 1 year ago

Hi, I'm looking for a way to split a .wav file with embedded cue sheet (BWFMetaedit can export it just fine as XML). This seems to be a bit out of scope for this project maybe, unless I'm missing something. Any suggestions would be appreciated. I'm not sure either how to process the exported XML cue sheet - all the required information is in there but I don't know what other software can digest it as-is. I would like to avoid writing a script , but that is currently my only idea (e.g. parse that xml and run multiple ffmpeg commands)

Thanks !

If you do not need to do this in batch, Audition at least can do it for one file.

@MarcosSueiro Thanks for the reply. Unfortunatly I don't use Audition, and anyway I did want to batch-process a few files !

Additional information : the 'cue' chunks are not actually part of the BWF or extended headers as I initially thought, but are in fact defined in the very first WAV specifications of 1991. Also, I learned only today that ffmpeg could parse those chunks as "chapters". Still needs a bit of scripting to automate the splitting but a fairly neat solution.
