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.

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.

Foobar ~ Waveform Table Seekbar

Enhance the appearance and functionality of Foobar2000 by adding a visual 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.

Sonic Visualiser ~ View & Analyze Audio Files

The aim of Sonic Visualiser is to be the first program you reach for when want to study a musical recording rather than simply listen to it.

We hope Sonic Visualiser will be of particular interest to musicologists, archivists, signal-processing researchers and anyone else looking for a friendly way to take a look at what lies inside the audio file.
