Qt-based software for audio measurement (speaker parameters, frequency and phase response, etc).

This project provides two binaries, mostly identical in features: a command line application (using libpopt for option parsing), and a graphical application (using libgtkmm (version 2) for the GUI and libao for sound playing). It uses spectral modelling techniques for parameterized sound analysis and synthesis. For the analysis phase an STFT is done (using libfftw for doing FFTs), and then harmonic/sinusoidal analysis. For the synthesis phase additive synthesis is used. Using libsndfile for sound loading and saving allows to support many uncompressed sound file formats (WAV, AIFF, AU, headerless RAW, ...), and also OGG and FLAC, but MP3 isn't supported. Available parameters include window type, size, and overlapping; sinusoid discarding; equalization; time strechting, frequency scaling and shifting; frequency and amplitude interpolation; normalization; dynamic range compression and expansion, etc. ...

WaoN is a Wave-to-Notes transcriber (converts audio file into midi file) and some utility tools such as gWaoN, graphical visualization of the spectra, and phase vocoder for time-stretching and pitch-shifting.

Sculptor is a phase-vocoder-based package with real-time capabilites. You can use it to fiddle with soundfiles in the frequency domain, changing pitch and duration independently.

This project will try to develop an audio analyser which displays several informations as phase in 2 ways (1 dimensional and 2 dimensional), waves shapes, spectrogram in full range and by 1/3 octavia with the value of the current peak frequency, and meter
