This code implements automatic gain control for audio signals, which attempts to apply a smoothly-varying gain to an audio waveform in order to keep its energy close to some target level. This version also tries to balance the energy in individual frequency bands. It works by taking the...

SonaSound is a real-time music visualisation tool using either soundcard input or playing files to the soundcard output. It features a waveform-, a short-time spectral- and a sonogram display for music application. It tries to be as accurate as possible, not as beautiful as possible.
