    In order to capture, store, and reproduce a signal accurately, snapshots, or samples of the incoming signal are taken at a specific rate, a sampling rate, measured in Hertz Hz.

    In order to reproduce the full spectrum of a musical signal, a sampling rate of 44,Hz, or Sample Rates From masteringthemix. There are many arguments for using higher sample rates than For most consumers, It is the most commonly used rate for music. Using this sample rate allows accurate reproduction of frequencies up to Hz, just above the limit of human hearing.

    Lower rates can be used when critical listening is not required, such as with speech. Bit Depth For music, the bit depths you will come across are 16bit and 24bit.

    While the sample rate is concerned with capturing frequency accurately, bit depth is related to dynamic range. Dynamic range is the distance between the quietest and loudest sounds in a piece of music, and the quality of the resolution within this range. While 16bit is still very common, 24bit is now becoming more widely used for Hi-Res HD audio. Consumers can now purchase music in lossless formats that support higher sample rates and bit depths.

    Bitrate Bitrate is the measure of the rate at which data is transferred from one point to another. It is measured in bits per second bps , kilobits per second kbps , or megabits per second Mbps. We also use bitrate to describe the fidelity of audio files. An MP3 file that was compressed at kbps, will have a much better dynamic range and sound quality to one compressed at kbps. With higher bitrate, audio files with higher bit depth and sample rate can be sent wirelessly, thus increasing the quality of the audio.

    However, this means an increase in bandwidth used for transmission. Codecs have the ability to alter the rate at which the data is being sent, directly affecting quality. HD Audio As internet speeds have increased and technology has developed, lossless formats have become more popular as a means to distribute and purchase music.

    Music streaming platforms like Qobuz and Tidal are already using lossless files. 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.

    Which codec you use will inevitably be linked to the equipment you have. But if you are entering the world of Bluetooth audio, or upgrading, knowing the qualities of the different codecs is important. Other the codecs itself, there are other factors that can directly affect the quality of the Bluetooth Audio: Distance between the transmitter and receiver: The further the two devices are away from each other, the less stable the connection will be.

    This decreases the speed of transmission, thus resulting in stuttering audio. Keep the distance as close as possible. The number of blockages between the transmitter and receiver: Bluetooth can travel through the walls. But take note that once the signal pass through walls, the signal strength is attenuated and the range decreases.

    Having a lot of blockages may result in the issue where Bluetooth headphones are connected but has no sound. 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. Bluetooth versions: Even though Bluetooth has now been the standard for wireless connectivity, it is still far from perfect. Having a lower Bluetooth version may result in different audio problems that may have already been solved in latter versions.

    As such, every Bluetooth device you have will be compatible with this codec, and they will communicate with each other without any issues. If there are any codec mismatches, your device will default to using the SBC codec. Unlike nearly all the other codecs discussed here, SBC is public domain, so equipment manufacturers can use it for free. SBC has a bad reputation among the Bluetooth audio codecs for its high lossy compression algorithm and hence, overall lower audio quality.

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

    It is also able to transmit data at rates as high as kbps. A more realistic bitrate will be kbps which is roughly equal to the quality of MP3 recording. You will run into latency issues when using this codec for gaming and watching streams. This issue is not exclusive to this codec. When it applies lossy compression, it can produce better results than SBC.

    It is the successor to MP3 and provides improved audio quality results when using similar compression settings kbps. This improvement comes at a cost, more power consumption. AAC is not in the public domain, so manufacturers have to pay the patent holders to implement it in their technology.

    Although it is the default codec on iOS devices, it is not owned by Apple. How each manufacturer implements it makes a big difference. Its implementation and audio quality are generally much better on iOS than Android devices.

    Some of its specs may look similar or less than SBC, but it is a more advanced codec, and you hear the benefit of that. Also not public domain, Qualcomm charges manufacturers to implement it. They also provides a record of all devices that implement its codecs.

    Bottom-line How Bluetooth Codecs Work Codecs determine the way data will transmit the Bluetooth from the source to the headphones. Regardless of the type you choose, they encode and decode digital audio data to the destined format. Low bit rates are responsible for low audio quality and higher compression, but a higher one means better audio quality and less compression. Initially, it was used to deliver CD-quality sound over Bluetooth connections, and it uses compression to beam the data wirelessly and reduce latency.

    The AptX is the most popular Bluetooth codec as of and is supported by most Android smartphones. Qualcomm is the owner of this codec and is common in most expensive smartphones with Snapdragon SoCs.

    It supports HD audio transfers and up to kbps transfer rate. Therefore, you will enjoy a higher quality than CD, and it has a better signal to increase the definition in music. But for this codec to work, it must be compatible with the input and output device. The input devices include media players, computers, and smartphones, and the output devices are wireless headphones and other Bluetooth-enabled output devices. Most iPhones benefit from the hi-rise playback of the AAC that goes up to kbps.

    It also supports Android, but its performance is low owing to inconsistent and poor streaming quality. It is a power-intensive codec, and Apple has a well-maintained ecosystem that can handle it well. However, this is not the reality, and it offers three transfer modes: kbps, kbps, and kbps.

    But once they reach 20Hz, the two highest rates lose their fidelity, and here, the SBS and aptX even become between them. LDAC-supported headphones are rare in the market but if you find one, be ready to pay a hefty price. It offers three times higher data transmission than SBS and up to kbps bitrate and a max sample of 96kHz. The first phone to use this codec was the Huawei 10 Mate. LC3 LC3 is still a new entrant in the market and is not available yet.

    When you look at its technical specifications, you will know little about it, but a press release says it will replace SBC and become a default Bluetooth codec. Also, it will have lower latency requirements and minimal power consumption making it best for modern use.

    This option gives you more choices to tweak your phone to suit your needs. After activating the developer options, you can access it anytime you want to. Open Bluetooth in your phone and scan for your wireless headphones.

    Pair them and connect to the Android smartphone. The option will display numerous Bluetooth audio codecs. Pick another one apart from the SBC option. Provided your wireless headphones support your chosen audio codec, it will increase the sound quality. Bottom-line When Bluetooth technology was introduced, you had limited audio codecs to use with your input device. However, after many companies continued to get the headphone jack out of the market, many codecs have sprung up, improving audio quality and reducing latency.

    Well, you need to invest in high-quality headphones that support different Bluetooth audio codecs for the optimum sound experience.

    Other the codecs itself, there are other factors that can directly affect the quality of the Bluetooth Audio: Distance between the transmitter and receiver: The further the two devices are away from each other, the less stable the connection will be. This decreases the speed of transmission, thus resulting in stuttering audio. So with the remaining macOS, Android, and Ubuntu, there is a workaround to change Bluetooth audio codec.

    A codec is a short form of Coding and Decoding. In case of wireless earphones, the audio signal is coded and then send to the earphones where it is decoded. It has a healthy lossy sound compression, less-power consumption, and noticeable latency. However, there are ways to force the OS to use better Bluetooth codecs and get the best audio quality all the time. Android The most straight forward method is in Android. Android devices are aptX and AAC compatible and will run at highest codec if your headphones are compatible.

    To force or change the Bluetooth codec first, you have to connect the headphones to your Android device. Next, start playing a song on your phone because this is the time the codec gets active. After that, head over to the Settings menu and move to Developer Options. Here, you will have different audio codecs to choose from.

    The thing with Bluetooth audio codecs is that both the devices need to support the codec else no audio will be played. By default, the best audio codec will be selected. Android also provides other customizations for audio like Bluetooth audio sample rate or Bluetooth Audio Bits Per Sample. You can modify these settings but make sure that your headphones support the particular sample rate and bit streaming.
