This makes the BackbeatPro2 and other headphones with this technology ideal for these activities.īased on our tests, we have found that the best Bluetooth audio codec has a greater impact on latency than on sound quality.
The aptX-LL codec was excellent when we tested it by watching some movies and playing some games. The aptX improves the performance of the SBC, but It's the aptX-LL that has the biggest impact in terms of results.

On the other hand, CSR developed the low latency aptX code to fix these connection problems. The SBC connection has about 100 ms of delay, which is noticeable when watching videos and can ruin certain gaming experiences. Latency, or delay in wireless audio playback, is where the aptX codec separates itself. The resulting measurements, however, for both frequency response and harmonic distortion, are very similar between the aptX and SBC codecs. The audio differences are subtle in the SBC vs aptX fight but can be noticeable to expert and critical ears. It's not particularly noisy, although, in the signal-to-noise ratio, the aptX has a higher optimum loudness range. We find that the standard SBC codec works well for most audio applications.

AAC? Since Culturasonora does not have a reliable means of measuring the AAC and LDAC formats wirelessly, we have compared the SBC and aptX codes using a Plantronics Backbeat Pro 2 headset: aptX and SBC sound quality However, it's somewhat limiting because both the transmitter and receiver must have aptX capability for this codec to work.īCS vs. aptX HD? The aptX codec is ideal for demanding audio applications because it encodes audio more efficiently and accepts more information than SBC.Īdditional variations, such as aptX (LL) and aptX (HD), drastically reduce wireless latency and improve sound quality. As a drawback, we should mention that it's not very common to find it in headphones.īCS vs. The AAC codec is very popular thanks to the Apple iTunes platform. AAC? The Bluetooth AAC codec is similar to SBC but provides better sound quality. This is especially noticeable when using inexpensive Bluetooth transmitters. However, the audio may be inconsistent in some situations. The SBC codec provides very decent quality audio and doesn't require much processing. The Bluetooth SBC is capable of transmitting up to 328kbps with sample rates of 44.1 kHz. The SBC codec is the codec found in most wireless devices and is found in all Bluetooth headsets with A2DP (Advance Distribution Profile). What is the best Bluetooth audio codec? Here are their differences. aptX? The three main codecs that most users will encounter are SBC, AAC, and aptX. However, this codec has a relatively high latency and can be somewhat noisy.īCS vs. The SBC code is the standard algorithm for most Bluetooth devices. The codec efficiency determines the quality of the audio information that will be sent.
Sony has its LDAC codec and Qualcomm offers aptX.ĪAC vs SBC vs aptX codec which is the best?Ĭodecs are encoding algorithms that compress audio to handle sound packets for fast wireless transmission.

CSA? aptX vs AAC? To provide greater consistency for users of Bluetooth products, several companies have developed their Bluetooth codecs, and then offer the license to other production houses.ĪAC is one of these formats, a successor to MP3, used by Apple and others. This means that the variants among the Bluetooth codecs are compatible with different audio devices, as well as providing different connection and sound qualities.Īll Bluetooth devices support the standardized SBC (Low Complexity Subband Coding) codec, but implementations of SBC have varied in quality throughout the history of this technology.īCS vs. It's used to transmit stereo audio through a source device, such as a telephone, computer, television, etc., to a receiver, such as wireless speakers or headphones.ĭifferent codecs send audio information using different formats and may introduce their compression technologies to maintain a balance between sound quality and the information packet of the audio files.Ĭompression may sound like a bad thing for lovers of high quality audio, but It's necessary if we are going to send large files wirelessly. In other words, It's the process by which the zeros and ones of binary digital data are formatted.

The word codec, when talking about wireless audio, means the software method of encoding a stream of audio information that is sent wirelessly between two devices.
