In lossless mode the amount of compression obtained +depends on the nature of the waveform. Those composing of low +frequencies and low amplitudes give the best compression, which may +be 2:1 or better. Lossy compression operates by specifying a minimum +acceptable segmental signal to noise ratio or a maximum bit rate. Lossy +compression operates by zeroing the lower order bits of the waveform, +so retaining waveform shape. |
