I recently downloaded a pack of keygen chiptunes (via http://keygenmusic.net/), and most of them are in file formats such as .xm, .mod, etc. I'd like to convert them all to mp3, hopefully using a tool like avconv (so I can batch process them).

However, when I issue avprobe <filename>, I get the following error:

avprobe version 9.18-6:9.18-0ubuntu0.14.04.1, Copyright (c) 2007-2014 the Libav developers
  built on Mar 16 2015 13:19:10 with gcc 4.8 (Ubuntu 4.8.2-19ubuntu1)
2000AD/2000AD - Creatures To The Rescue +3 trn.mod: Invalid data found when processing input
# avprobe output

How can I convert these files to mp3 format?

Also, here is a list of all the filetypes I need to convert:

   24 ahx
    2 amd
    4 bp
    7 d00
    4 fc13
   15 fc14
    6 hsc
  217 it

Use ffmpeg. It has support for the external libraries libopenmpt, or the older libmodplug, which are needed for module files. You'll need to get or compile ffmpeg with --enable-libopenmpt or --enable-libmodplug.

avconv is missing this capability, among many other things.

  • I compiled ffmpeg with --enable-libmodplug and now I can convert it, mod s3m, xm to mp3. For some reason I cannot convert mp3 to any of those formats. When I try "ffmpeg -i file.mp3 file.mod" I get the error "Unable to find a suitable output format for file.mod"

    @sergio These external libraries are demuxers only and do not enable encoding of these formats. FFmpeg does not have support for encoding of module and tracker files.

    Saving a MOD/XM/S3M/IT as MP3 is the equivalent of saving a Photoshop PSD as a JPEG. MP3 and JPEG is the "merged" format - can't be converted back to the complex format that PSD and MOD/XM/S3M/IT is.
