"Bluetooth's default codec is SBC, which provides the lowest audio quality and prioritizes connection stability. Other codecs, such as LDAC, AAC, and AptX, provide more data transmission and can deliver near-lossless quality. The issue is that these codecs aren't standard; AAC can be inconsistent on Android, and LDAC and AptX codecs require manufacturers to pay licensing fees."
"The Bluetooth SIG's goal is to enhance its LE Audio Bluetooth radio to support hi-res and lossless audio via high-data throughput, thereby standardizing the technology across brands and manufacturers."
"A digital audio file is considered lossless when fidelity is preserved, and the song retains all original audio detailing. Lossless audio files are larger, require higher data transfer rates, and use more processing power. Therefore, lossless audio files aren't compatible with current Bluetooth bandwidth standards."
Bluetooth audio transmission currently relies on lossy playback, limiting options for high-resolution audio enthusiasts. The Bluetooth Special Interest Group is working to standardize wireless lossless audio, spatial audio, and surround sound capabilities. Current Bluetooth uses the SBC codec for stability, while alternative codecs like LDAC, AAC, and AptX offer better quality but require manufacturer licensing fees and lack standardization across platforms. The SIG aims to enhance LE Audio Bluetooth radio to support hi-res and lossless audio through increased data throughput. Lossless audio preserves complete fidelity but requires larger file sizes, higher data transfer rates, and more processing power than current Bluetooth bandwidth standards support.
