Sound : Recollection from the compression chapter

Sampling Rate / Digitisation

CD : 44.1 kHz

22kHz Useful enough for most people

Human Voice : 8kHz is enough

Quantisation / Range reduction

Remember Ravel's Bolero

16 or 8 bits x 2 (stereo) or number of channel

From 8 bits to 6 bits ...

Bit Rate : define the quality of the compression (128 kbps for instance)

Other reminder

Download vs Stream

Unicast vs Multicast
