Hi guys,

do you by chance happen to know a tool or combination of software tools that would do the following automation (so i won't need to do that in audio editor by hands each time):

I throw 3 or more MP3 files to a program, that would make WAV files off them with the bit depth, frequency and mono/stereo settings that i'll set, and merge/combine these few files into one WAV file, and then this result WAV file would get encoded to ACC (m4a) file with the bitrate and settings that i'll configure.

Actually, there are tools to batch convert wav to other formats, so if there is no such universal tool to make all steps of the job, it's no big deal. The main goal is to make a batch job list with few mp3 files per job and batch convert everything....

I need to make like 100 or more of such "jobs" that later i'll use the ACC files to be muxed into MP4 video containers as sound streams... And making every task by hands in audio editor would take half of my life

Thanks in advance for your valuable know-hows
