DFasma ~ Compare Audio Files In Time & Frequency

DFasma is free open-source software which is used to compare audio files in time and frequency. The comparison is first visual, using wavforms and spectra. It is also possible to listen to time-frequency segments in order to allow perceptual comparison. It is basically dedicated to analysis. Even though there are basic functionalities to align the signals in time and amplitude, this software does not aim to be an audio editor.

  • Shows spectrogram, amplitude, phase spectra and group delay.
  • Can play a filtered sound given a selected frequency band.
  • Rectification of the spectrogram tilt (cepstral lifting).
  • Can create and edit segmentation files.
  • Can create and edit fundamental frequency (F0) files (thanks to REAPER).
  • Runs under Linux, Mac OSX and Windows.

Tau Analyzer ~ Audio Source Verification

Tau Analyzer is a free program, which can help you to distinguish with reasonable accuracy the original studio-based CDs from poor quality fakes, that have been “reconstructed” using a lossy audio source, such as mp3. Using this program you can check the authenticity of your purchased or borrowed music CDs.

Tau Analyzer features an intuitive user interface, allowing users to work directly with audio CDs, and has some additional functions such as spectrum and frequency analyzers, ATIP and ISRC data readers, etc.

beets ~ The Music Geek’s Media Organizer

The purpose of beets is to get your music collection right once and for all. It catalogs your collection, automatically improving its metadata as it goes using the MusicBrainz database. Then it provides a bouquet of tools for manipulating and accessing your music.

Because beets is designed as a library, it can do almost anything you can imagine for your music collection. Via plugins, beets becomes a panacea:

  • Fetch or calculate all the metadata you could possibly need: album art, lyrics, genres, tempos, ReplayGain levels, or acoustic fingerprints.
  • Get metadata from MusicBrainz, Discogs or Beatport. Or guess metadata using songs’ filenames or their acoustic fingerprints.
  • Transcode audio to any format you like.
  • Check your library for duplicate tracks and albums or for albums that are missing tracks
  • Browse your music library graphically through a Web browser and play it in any browser that supports HTML5 Audio and lots more.
