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 waveforms 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.

Features:

  • Can load about 25 different audio formats (thanks to libsndfile or libsox).
  • 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.

ORBAN Loudness Meter ~ Loudness & Peak Display


This software simultaneously displays instantaneous peaks, VU, PPM, CBS Technology Center loudness, and ITU BS.1770 loudness. All meters include peak-hold functionality that makes the peak indications of the meters easy to see.

The software accepts two-channel stereo inputs. The VU and PPM meters are split to indicate the left and right channels. The PPM meter also displays the instantaneous peak values of the L and R digital samples. ~ Hydrogen Audio

Foobar2000 ~ Playlist Viewers


Foobar2000 Playlist Viewers display the current playlist of songs. Different playlist viewers offer various capabilities such as formatting, grouping and visual options. A playlist viewer is usually the central panel and main focus of a Foobar2000 interface. Foobar2000 plays the next song of the current playlist unless the play order has been changed from default, to repeat, random or shuffle. There is a playback queue but it is not visible or used in normal operation.

Adding a custom column to a playlist view: (using play count as an example)

  • When adding a column view in a playlist, you’ll need to define the column first.
  • Navigate to Preferences > Display > Default User Interface > Playlist View > Custom Columns
  • at the bottom of the custom columns windows, click “Add new‘
  • Name the Column “Played‘ and %play_count% as the ‘pattern’
  • click apply, ok
  • Now right click the title bar of the playlist and select “Columns” and make sure ‘Played‘ is selected (checkmarked) and that you can see the column in the playlist, it will be last but you can rearrange it.
