FlacSquisher ~ Lossless to Lossy Conversion


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

MP3Packer ~ Shrink Or Change MP3s CBR / VBR


MP3packer is a program which can rearrange the data within an MP3 to fulfill specific goals. By default, the program generates the smallest MP3 possible (with the least padding). However, many people also use it to turn VBR files into CBR for use with players which don’t support VBR.

It can save space by storing frame data in the smallest possible frame. Usually MP3s are already stored in the most efficient way possible. However, for high-bitrate CBR files (like -b 320) there can be a lot of wasted space. ~ HydrogenAudio

CUETools ~ Lossless Audio / CUE Sheet Conversion


The goal is to make sure the album image is preserved accurately. A lossless disc image must be lossless not only in preserving contents of the audio tracks, but also in preserving gaps and CUE sheet contents. Many applications lose vital information upon conversion, and don’t support all possible CUE sheet styles.
