CC256x A2DP Latency.

Jesse Wang

While using CC2564B for BT A3DP Audio Source and Sink design with MSP430, what is the audio latency from Source to Sink? What parameters and how can I optimize the latency to be less than ~30ms?

Hi,

Let me check it internally and get back to you on this.

Hi,

The latency can only be controlled up to some extent by changing the bitpool (increasing its value). As it is dependent on the many things like remote device, environment you are testing..

The minimum latency where the user will not hear any audio break is around 80ms. This is mostly derived by the jitter buffer whose purpose is to overcome any interference.

In most headsets, this jitter buffer is around 300ms.
