Bluetooth Audio Delay Experiment - aptX Low Latency vs others
Priva III 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|
|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.
