The most important thing to remember is that some codecs are better than others when it comes to streaming music over Bluetooth, and those are the ones that you ideally want to have your source and Bluetooth headphones to support to help ensure a smoother listening experience. There are several Bluetooth audio codecs available and each one has its own unique formula for compressing and transmitting audio data. Then, it decodes that compressed data so it can be converted into an audio signal that we can hear. During the compression stage, it reduces the file size of the audio data (so it wouldnвЂ™t eat up too much bandwidth) and encodes it in a certain format for transmission. There are 4 important elements that will affect your listening experience when using Bluetooth headphones:ДЄ Bluetooth codec is an algorithm that compresses, encodes, and decodes digital audio data. Factors that Affect the Quality of Bluetooth Audio As youвЂ™ll learn in a bit, there are several factors that come into play that determine if youвЂ™ll have near-imperceptible audio latency or experience some noticeable delay. Note that while wired connections are better in terms of audio latency, using Bluetooth headphones doesnвЂ™t necessarily mean youвЂ™ll hear noticeable sound delay all the time. youвЂ™re listening to a lossless audio file), then the transfer wonвЂ™t go as fast and smooth, and this will reflect as audio stutter and lag. If there isnвЂ™t enough bandwidth to support a particularly large audio file transmission (e.g. If the traffic exceeds what the road size can accommodate, traffic jams will happen, reducing movement to a slow crawl (more time required to complete the transmission). Think of bandwidth as the size of the road while the audio file size is the amount of traffic. The bigger the audio signalвЂ™s file size (higher quality equates to larger audio files), the more bandwidth it needs to get to the receiver. This audio signal uses a certain bandwidth to вЂњtravelвЂќ from source to destination. The transmitter sends the audio signal to the receiver. To give a brief background, in a Bluetooth audio chain, you have a transmitter and a receiver. Now, you may ask: Why do wireless headphones have higher audio latency than wired? In a wireless connection, Bluetooth latency can go anywhere from an ideal 34 ms (aptX LL) up to 100-300 ms for true wireless earbuds and headphones. In a regular wired connection, the typical audio latency is 5-10 ms. These are the milliseconds (ms) it takes to process digital data and convert it to an audio signal that can be streamed through a wired or wireless connection to your headphones. Audio latency is defined as the time it takes for audio data to travel from its source (computer, smartphone, mp3 player) to your headphones or speakers.
