As the file gets compressed – the file size is reduced to lessen the usage of bandwidth. Bluetooth Codecīluetooth codec works like an algorithm that performs certain actions to transfer a file.īluetooth codec receives the file, compresses, encodes, and decodes the audio file. When we talk about the factors that affect the Bluetooth audio quality – these 4 are the biggest bystanders in it. 4 Factors that Affects Bluetooth Audio Quality and Cause The Delay in Audio? And consider a wired connection as a train track – that will help in a faster transmission than a wireless connection. Just like you need a bigger car to move more stuff – similarly the bigger the audio file is, the more bandwidth is used to transfer the audio file. And the audio travels with a bandwidth to get transferred from system A to system B. The transmitter will send audio signals to the receiver. In a Bluetooth audio chain, there is system A (the transmitter) and system B (the receiver). Let me dissect in detail why is there a lag in audio transmission so you understand the phenomenon in detail. ![]() The auxiliary wire connection takes about 5-10 MS to transfer the audio whereas in the case of a wireless Bluetooth connection – the delay in audio can go up to 100-300 for wireless speakers or headphones. ![]() It happens because audio files take time to get transferred from the sender to the receiver. Now there is a valid question to ask – do Bluetooth speakers have a delay? It happens mostly when we are using a Bluetooth audio device like Bluetooth speakers. While enjoying our favorite movie, you might notice that the video and the audio do not match seamlessly.
