Video and Audio

AAC
requires a license for both encoding and decoding. AAC is the least complicated and most widely used codec.
If achieving the best possible audio quality is a priority, AAC is the recommended codec to use. An AAC license
is included in the Axis product.
Sample rate -
The number of times per second the sound is sampled. A higher sample rate will provide better audio quality, but
also requires a greater bandwidth.
Bit rate -
Set the required bit rate depending on the selected encoding. A higher bit rate will give better audio quality. A lower bit
rate may have latency or delay, but will require less bandwidth.
