Priva II (BTTC-318-WHT) - audio delay with different audio codec / Comparison with SBC, aptX and aptX Low Latency?

Bluetooth Audio Delay Experiment - aptX Low Latency vs others


Priva II has incorporated the latest "aptx low latency" codec technology, for transferring superior stereo quality sound without any noticeable delay. 

To take advantage of the better performance of aptX Low Latency codec, the headphones, speaker or receiver must support the same codec. If the headphones, speaker or receiver only supports the normal aptX codec, or the SBC one, these codecs will be used instead.

Audio delay when paired with different headphones / speaker / receiver

Headphones / speaker / receiver support-  The audio delay will be 
aptX Low Latency codec ~ 40ms
aptX codec  ~ 70ms
Fast Stream codec   ~ 40ms
AAC codec  ~120ms
SBC codec (most standard Bluetooth audio)  ~ 220ms

Note: Audio delay for Fast stream codec is almost the same as aptX LOW Latency codec, but the audio quality of the aptX LOW Latency codec is much better.
