It is able to support up to the 48 kHz sampling rate at 16-bit bit depth. But in fact, SBC is a pretty flexible codec.

SBC has a bad reputation among the Bluetooth audio codecs for its high lossy compression algorithm and hence, overall lower audio quality. Unlike nearly all the other codecs discussed here, SBC is public domain, so equipment manufacturers can use it for free. If there are any codec mismatches, your device will default to using the SBC codec. It is integrated into the Advanced Audio Distribution Profile (A2DP) – a set of default Bluetooth specifications for streaming audio over Bluetooth.Īs such, every Bluetooth device you have will be compatible with this codec, and they will communicate with each other without any issues. SBC or “Low Complexity Subband Coding” is the first Bluetooth codec introduced to transfer audio.

Supports bit rates up to 345kbps (realistically 256kbps).

Having a lower Bluetooth version may result in different audio problems that may have already been solved in latter versions. That’s why, Bluetooth’s manufacturers are still continuously upgrading its features and fixing bugs.

Bluetooth versions: Even though Bluetooth has now been the standard for wireless connectivity, it is still far from perfect.

Electrical interference by other devices: As Bluetooth signals are electromagnetic waves, they can be affected by other interfering electromagnetic wave-emitting devices such as radio, mobile phones, etc.

Having a lot of blockages may result in the issue where Bluetooth headphones are connected but has no sound. It doesn’t need to have line-of-sight between two devices but as least keep them within the same room. But take note that once the signal pass through walls, the signal strength is attenuated and the range decreases.

The number of blockages between the transmitter and receiver: Bluetooth can travel through the walls.

This decreases the speed of transmission, thus resulting in stuttering audio.

Distance between the transmitter and receiver: The further the two devices are away from each other, the less stable the connection will be.

Other the codecs itself, there are other factors that can directly affect the quality of the Bluetooth Audio: Other than Codecs, What Affects the Quality of Bluetooth Audio?

But if you are entering the world of Bluetooth audio, or upgrading, knowing the qualities of the different codecs is important.

Which codec you use will inevitably be linked to the equipment you have. If HD audio is something that is paramount for you, you will need to choose equipment that implements codec(s) that can deliver the result you need. Music streaming platforms like Qobuz and Tidal are already using lossless files.ĭigital HD formats such as FLAC, ALAC, WAV, and AIFF, are the choice of audiophiles and music collectors who are moving away from the physical medium. HD AudioĪs internet speeds have increased and technology has developed, lossless formats have become more popular as a means to distribute and purchase music. Chart comparing the bitrate of different formats: MP3, CD, and HD audio.Ĭodecs have the ability to alter the rate at which the data is being sent, directly affecting quality.
