The codec operates on each 16-bit audio sample and generates a 4-bit ADPCM sample. The ADPCM algorithm is a waveform coding technique which predicts the current signal value from the previous values and transmits only the difference between the real and predicted value. The codec is widely deployed in Windows and Macintosh operating systems. adpcm sound codec Gratis download software a UpdateStarK-Lite Mega Codec Pack è una raccolta di codec, filtri DirectShow e strumenti.Filtri DirectShow e di codec sono necessari per la codifica e decodifica riproduzione audio e video formati.

Adaptive differential pulse code modulation is a very efficient digital coding of waveforms that was developed by Bell Labs in the 1970s for the purpose of voice coding. ADPCM was also used in the early 1990s by Interactive Multimedia Association IMA for the development of legacy audio codec - also referred to as ADPCM DVI, IMA ADPCM or DVI4. effective and preserves good audio quality. The ADPCM codec, which is based on coding waveforms in time domains, is much less complex than codecs based on voice perception vocoders that operate in frequency domains. For these reasons, the ADPCM codec is the best choice for the audio output on 8-bit microcontrollers.
