The basic premise of the encoder is that most audio, and particularly speech, can be synthesized from only sinusoids and noise. The encoder describes individual sinusoids with amplitude and frequency,… …   Wikipedia

  • Dark frame — A dark frame is a photography technique to identify noise in a CCD imaging device. This is done by recording without exposing the CCD, usually by leaving the shutter closed and putting the CCD in a dark room. These dark frames are then subtracted …   Wikipedia
