Sometimes, size compressed audio is called as bitstream. Throughput limitation of communication channels (or audio interfaces).Ĭompression may be lossless or cause sound quality losses. From design point of view, digital audio technologies allow to achieve lower distortions, than analog ones.Īnd other) contains musical signal in this PCM format.Īudio data may be size compressed to solve issue of: Main advantage of discrete values, is ability to transmit/store with control of a errors and technical opportunity to recover it (when special coding are applied). So, the signal should be represented as discrete values (samples), that may be stored into computer memory.īefore listening, these discrete values should be transformed back to continuous signal. The point is computer can't store continuous things like analog audio signal.
