What is Bluetooth Audio Codec

Bluetooth audio codec refers to the audio codec technology used in Bluetooth audio transmission.

Common Bluetooth audio codecs

Common Bluetooth audio codecs on the market include SBC, AAC, aptX, LDAC, LC3, etc.

SBC is a basic audio codec widely used in Bluetooth headsets, speakers and other devices. AAC is a high-efficiency audio codec mainly used on Apple devices. aptX is a codec technology developed by Qualcomm that provides better audio quality and lower latency for high-end Bluetooth audio devices. LDAC is a codec technology developed by Sony, which can support high-resolution audio transmission up to 96kHz/24bit, and is suitable for high-end audio equipment.

The Bluetooth audio codec market continues to grow as consumer demand for high-quality audio continues to increase. In the future, with the popularization of 5G technology and the continuous upgrading of Bluetooth technology, the Bluetooth audio codec market will have a broader application prospect.

Bluetooth Audio Codec

LC3 Bluetooth audio codecs

Among them, LC3 is a codec technology developed by SIG[F1] , which can provide higher audio quality and lower power consumption. Compared to the traditional SBC codec, LC3 can provide higher bit rates, resulting in better audio quality. At the same time, it can also achieve lower power consumption at the same bit rate, helping to extend the battery life of the device.

LC3 technical features, including:

  • 1. Block-based transform audio codec
  • 2. Provide multiple speeds
  • 3. Support frame intervals of 10 ms and 7.5 ms
  • 4. The quantization bit width of each audio sample is 16, 24 and 32 bits, that is, the PCM data bit width
  • 5. Support sampling rate: 8 kHz, 16 kHz, 24 kHz, 32 kHz, 44.1 kHz and 48 kHz
  • 6. Support unlimited number of audio channels

LC3 and LE Audio

LC3 technology is a supporting feature of LE Audio products. It is an audio transmission standard in Bluetooth low energy technology. It will support multiple audio codecs to provide better audio quality and lower power consumption.

In addition, LE Audio also supports other codec technologies, including AAC, aptX Adaptive, etc. These codec technologies can provide better audio quality and lower latency, helping to improve the performance and user experience of Bluetooth audio devices.

In short, LE Audio will bring more codec technology options for Bluetooth audio devices, so as to meet the needs of different users for audio quality and power consumption.

LE Audio Bluetooth Module

Feasycom also develops Bluetooth modules based on LE Audio product technology. With the release of new products such as BT631D and BT1038X, they can provide better audio quality and lower power consumption, and also have multiple functions and features. Excellent choice for developing Bluetooth audio devices.
