It's quite similar to wavesurfer. Though, I hope it is more convenient for
inspecting spectral characteristics (amp, phase, group-delay spectra).
It helps me for developing vocoders for speech synthesis. I used it also
for visualising results of voice transformation (e.g. pitch or time
scaling).
A quick look at the screenshots section gives some use cases:

Or just download it, load two similar, bot not equal sounds, and have fun!
Cheers,

really neat - though, could you give use quick use cases, when would who
needs it?) but it made into a news item on LMP

Greetings,
I felt we lack a light, quick and efficient tool to compare waveforms.
DFasma is quite convenient for inspection of results of synthesis and
modification tasks on voice signals.

* Shows spectrogram, amplitude spectrum, phase spectrum and group delay.
* Can play a filtered sound given a selected frequency band.
* Rectification of the spectrogram tilt (cepstral lifting).
* Can create and edit fundamental frequency (F0) files (thanks to REAPER).
* Can create and edit segmentation files.
* Can load about 25 different audio formats (thanks to libsndfile).
* Everything runs under Linux, Mac OSX and Windows.
Have fun ! And any type of feedback is welcomed of course.
Cheers,
Gilles
