5.3.8 Algorithms for Audio Companding and …
http://digitalsoundandmusic.com/5-3-8-algorithms-for-audio-companding-and-compression/
Let’s look at the steps in this algorithm more closely. 1. Divide the audio signal in frames. MP3 compression processes the original audio signal in frames of 1152 samples. Each frame is split into two granules of 576 samples each. Frames are …

MPEG-1: Bitrate of 1.5 Mbits/sec for audio and video About 12M. btis/sec for vdieo ,03M. btis/sec for audoi (Uncompressed CD audio is 44,100 samples/sec * 16 bits/sample * 2 channels > 1.4 Mbits/sec) Compression factor ranging from 2.7 to 24. With Compression rate 6:1 (16 bits stereo sampled at 48 KHz is reduced to 256 kbits/sec)

Other audio compression algorithms address speech-only applications or provide only medium-fidelity audio compression performance. For example, Code Excited Linear Prediction (CELP)[3] is a speech coding algorithm, while µ-law and Adaptive Differential Pulse Code Modulation (ADPCM) are relatively simple compression algorithms that can provide medium fidelity audio …
