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. Homepage: http://gillesdegottex.github.io/dfasma/ Downloads: https://github.com/gillesdegottex/dfasma/releases * 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
