Abstract
An audio data compression method improves over existing standards because of its encoding strategy for silence. The method analyzes the audio input to an encoder. If the audio is for an analyzed time frame is silence, a single byte output is generated by the encoder. If the next frame is silence, no output is generated. When a receiver receives the compressed data, and detects a one-byte silence signal, it can capture that signal and repeat it to a decoder. When the compressed signal reaches the decoder, it is decompressed into an analog signal.
