Bluetooth Audio Delay Experiment - aptX Low Latency vs others
Many Avantree Devices has incorporated the latest "aptx low latency" codec technology, for superior stereo quality sound without any noticeable delay.
To take advantage of the better performance of aptX Low Latency codec, the other side device must support the same codec. If the other side device or transmitter only supports the normal aptX codec, or the SBC one, these codecs will be used instead.
Audio delay when paired with different headphones/receiver-
|Headphones/Receiver support-||The audio delay will be|
|aptX Low Latency codec||~ 40ms|
|aptX codec||~ 70ms|
|SBC codec (most standard Bluetooth audio)||~ 220ms|
