What is Bluetooth Audio Codec

블루투스 오디오 codec refers to the audio codec technology used in 블루투스 오디오 transmission.

Common Bluetooth audio codecs

Common 블루투스 오디오 codecs on the market include SBC, AAC, aptx, LDAC, LC3, 등.

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. 미래에, with the popularization of 5G technology and the continuous upgrading of 블루투스 기술, the Bluetooth audio codec market will have a broader application prospect.

LC3 Bluetooth audio codecs

그중, LC3 is a codec technology developed by 말하다[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. 동시에, it can also achieve lower power consumption at the same bit rate, helping to extend the battery life of the device.

LC3 technical features, 포함:

  • 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 그리고 32 비트, 그게, the PCM data bit width
  • 5. Support sampling rate: 8 KHZ, 16 KHZ, 24 KHZ, 32 KHZ, 44.1 khz와 48 KHZ
  • 6. Support unlimited number of audio channels

LC3 and LE Audio

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

게다가, 오디오 also supports other codec technologies, including AAC, APTX 적응성, 등. These codec technologies can provide better audio quality and lower latency, helping to improve the performance and user experience of Bluetooth audio devices.

요컨대, 오디오 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 블루투스 모듈 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.
