aptX Low Latency Related Q&A



Q: Why should I use aptX Low Latency supported Bluetooth adapters?

Qualcomm aptX Low Latency audio ensures your Bluetooth enabled device can deliver sound in sync with visual media. With aptX Low Latency, it reduces delay to less than 40ms and improves end-to-end speed of the audio transmission, resulting in a high quality, synchronized user experience; you can enjoy the freedom of wireless for applications such as gaming and watching videos. 


Q: Does Avantree Bluetooth adapter support aptX Low Latency?

Most Avantree Bluetooth adapter, e.g. Priva, Audikast, Oasis, Oasis Plus, Saturn Pro, Leaf, have incorporated the Qualcomm aptX Low Latency codec (aptX LL). With a ≤40ms audio delay that is undetectable by human ear, making them ideal for watching TV/movies/video WITHOUT audio lag.


Q: Still experiencing a delay while using Avantree adapter?

If your Bluetooth headphone/speaker (e.g. Bose, Beats, Sony headphones) does not support aptX Low Latency, it will work with Avantree transmitter using aptX or SBC (Standard Bluetooth Codec) with about 70 -220ms latency, it is good for music but you may notice the lag between sound and picture while watching TV/movies.

If your Bluetooth headphone/speaker(e.g. Avantree Audition Pro) support aptX Low Latency, it will work with Avantree transmitter using aptX Low Latency with only 40ms latency which is not noticeable by human ears and ideal for enjoying TV/movies.
