Abstract
Pauses present in an input audio signal are detected and digitally encoded to represent the length of each pause. The audio signals are recorded; but the pauses included therein are replaced by respective pause encoded signals, thereby compressing the audio signals. When the compressed audio signals are played back, each pause encoded signal is sensed and is replaced by a pause whose length is derived from the encoded signal.
