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.

Subvert Audio ~ Encourage Musical Creativity


Subvert Audio is a music program designed to try and stimulate creativity in the user. To do this, it imposes certain restraints on the user, in an attempt to encourage more creative thought processes, and solutions to the problem these restraints introduce. In addition to the restraints imposed, Subvert Audio strives to encourage exploration of the program, and reward efforts to discover/create new ways of using it. It is, essentially, a program that is designed to be subverted, the idea being that in the process of doing so, the user’s creativity will be stimulated.

In some ways, the program is similar to graphical music programming languages such as Max/MSP et al. Indeed, prior knowledge of such environments could be seen as beneficial to Subvert Audio’s methods of stimulating creativity.

foo_wave_seekbar ~ Foobar2000 Waveform Seekbar


Enhance the appearance and functionality of Foobar2000 by adding a visual waveform representation of the currently playing audio track, which can be used to navigate to any point in the image of the track by clicking there.

Waveform Seekbar is a UI element for both the Default UI and Columns UI that provides seekbar functionality (seeking, position indicator) on top of a pretty image of the waveform of the currently playing song, drawn using either Direct3D 9.0c or Direct2D 1.0.
