I need a program which I can run using a .bat file to:
(1) copy DAB radio recordings from an SD card to HDD (I know the .bat file does this, not the audio software..!)
(2) convert DAB radio recordings to .mp3 at a quality which I can specify using command line
(3) split the .mp2 (or .mp3) file into smaller files, either of pre-set length, or split by 'track' - i.e. looking for Db level thresholds (set in command-line) to split at quiet / silent points
Summary:
What I want to be able do is write a batch file to copy DAB radio recordings (MPEG-2) from an SD card to HDD, then start a (digital audio) program which will convert the .mp2 to .mp3 and, for example, split a 98-minute file into 14 x 7-minute long files.
I'd also like to be able to set parameters to name the split files, based on (selected parts of) the original file name, but that's less important than the audio conversion and splitting from the command line.
I've been using "mp3 wma cutter" for some time, and it seems to do a moderately good job... (though I think the sound quality may be degraded and that the software introduces some clicks and hiss)... but I don't know whether or how I can run it from command line...
I think I could try using Switch then Slice (NHC software) but I don't know whether they'll run from command line..
The other issue is speed... I think "Mp3 WMA cutter" is OLD and probably doesn't make good use of dual core (centrino) processor... so a more up to date program, which will do this stuff fast would be great
