the limited audio fidelity, poor signal-to-noise ratio and poor cascading

properties. G.722 is not recommended for music applications.

6.1.1.6 Algorithm, Mode, Bit and Sample Rate

Since no single algorithm/mode/sample rate/bit rate combination is

ideal for all applications, the CDQPrima offers several different

combinations, each with advantages and disadvantages. In addition,

the full range of available algorithms insures that your CDQPrima can

connect with the widest number of codecs. The tables below compare

the available algorithms and bit rates. Recommended algorithm

combinations are indicated with a ü. In some instances, especially at

lower bit rates, using a lower sample rate will result in better audio,

with wider bandwidths and reduced artifacts.
