A Bluetooth audio codec is a technology that encodes and decodes audio signals to transmit them wirelessly over a Bluetooth connection. These codecs use various compression techniques to efficiently send as much audio information as possible within the limitations of Bluetooth bandwidth and speed (as noted in the reference from February 14, 2024).
Key Aspects of Bluetooth Audio Codecs
Here's a breakdown of important features related to Bluetooth audio codecs:
-
Encoding and Decoding: Codecs perform the crucial functions of encoding audio for transmission and decoding it upon receipt.
-
Compression: To maximize the amount of audio data that can be sent over Bluetooth, codecs use different compression methods.
-
Parameters: Codecs are characterized by their:
- Bits
- Bit rates
- Sampling rates
Generally, higher values in these parameters suggest better audio quality.
Why are Bluetooth Audio Codecs Important?
The choice of codec directly influences the audio quality you experience when using Bluetooth devices like headphones or speakers. Different codecs offer varying levels of compression and fidelity. The goal is to strike a balance between audio quality and efficient data transfer.
