FlacSquisher converts a library of FLAC files to MP3, Opus, or Ogg Vorbis format, maintaining the directory structure in the original library. That way, you can maintain your FLAC files for home listening, and easily convert them to MP3, Opus, or Ogg format for mobile use, where storage space is more often tightly constrained.
Features:
- Converts to MP3 or Ogg Vorbis
- Maintains directory structure from original library
- Takes advantage of multicore processors
- Can copy or ignore files by extension (album art, log files)
- Ignores files already encoded previously
- Compatible with Mono on Linux
