wav format conversions
Apr 1st, 2006, 10:52pm  
Hi. I need to convert wave samples from 8khz 16 bit mono to 44.1 khz 16 bit mono. Is there any server side software or library I can use to convert the formats either realtime. or at the time of upload to a server? Something similar to http://ffmpeg-php.sourceforge.net/ but with conversion functionality would be ideal. Thanks.

I think that ffmpeg-php will do what you need. It's just a frontend for ffmpeg, which looks like it can do conversion of one format WAV, to another format WAV.

The ffmpeg options you'd need would be
Code:
ffmpeg -i original.wav -ar 44100 -ab 16 -ac 1 converted.wav


No idea how that translates to ffmpeg-php code however.

EDIT: Having now looked at the ffmpeg-php docs, looks liek it onyl supports a very limited set fo the ffmpeg commands. However, if you have ffmpeg instealled, you can always use a PHP script to call the ffmpeg binary to do the conversion.
