thanks :)) niklas

are familiar ffmpeg? if installed on server, can try running on cli

ffmpeg -i input.flac output.mp3 

if works, can go on trying passing command application shell (if use example php application , debian linux hosting.)

to include bitrate can use

ffmpeg -i input.flac -ab 128k output.mp3 

or

ffmpeg -i input.flac -ab 320k output.mp3 

if can use it, see documentation: http://ffmpeg.org/ffmpeg.html possible, have use different command bitrate depending on version.
