While H. The common thread among all of the codecs mentioned in this article so far is that they are used for one purpose: compressing data. Data compression is used in everything from sharing video and audio over the internet to carrying a wireless audio signal from a smartphone to a pair of Bluetooth headphones. When data is encoded in a particular format to save space, a counterpart decoder is required to display that data on the other end.
Some codecs like the MP3 format are lossy, which means that some data is discarded in the compression format. Others, like FLAC, are lossless which means that no loss in quality can be discerned once the data is decompressed again on the other side. Codecs are also used for encryption purposes, as a means of making data accessible only to devices that possess the correct decoder. As time goes on, more and more devices can do it all. Modern computers, smartphones, and televisions are all equipped with hardware decoders that can handle formats like H.
If you are having trouble getting a video to playback on an older device, try converting the video to H. Use Google Fonts in Word. Customize the Taskbar in Windows What Is svchost.
Best Home Theater Systems. Best Smartwatches. Best Gaming Laptops. Best Smart Displays. It is characterized by higher bit rates and above all lower latency. In the HD version, aptX supports up to bit resolution, the maximum bit rate is kilobits per second at a sampling rate of 48 kilohertz. AptX without HD offers a maximum of kilobits per second at 48 kilohertz and a sampling depth of bit.
This is a real advantage, especially for gaming headsets or musical instruments. Regarding mobile phones, a big problem with AptX is that Apple does not support this codec. A recurring problem when talking about codecs, AptX Lossless requires support in both mobile and headset to kick in, which according to Qualcomm should happen starting in late , but with no expectation of compatibility with the iPhone family.
With AptX Adaptive, Qualcomm offers a sort of successor to AptX, which, however, is not yet found in many Bluetooth headsets on the market. As the name suggests, the codec is flexible and can switch between the advantages of the various AptX standards.
It also offers a low latency mode which is especially suitable for mobile games and movies. If low latency is not so important, AptX Adaptive achieves very high bit rates of kilobits per second to kilobits per second. Qualcomm specifies latency at just 80 milliseconds. If you want to further reduce losses when streaming music wirelessly, you should pay attention to the Bluetooth LDAC codec.
The codec offers a maximum of kilobits per second with a sampling depth of bit at 48 kilohertz. However, the default bitrate for devices is not specified. In this case, you have to go to Android developer settings to adjust it on your device. How to enable developer options on Android and unlock cool new features! But we will cover the best audio codec for iPhones owners later in this article. The LHDC codec is another standard with high bitrates.
In theory, it has been ready since Android 10 to be integrated into system interfaces by software developers. In practice, however, LHDC support is not as widespread. Here's an example:. However, although the flagship line is compatible, OnePlus doesn't extend the support to its entire product range, which means cheaper models like the OnePlus Nord 2 don't feature the new feature.
While LHDC is technically impressive, with bit rates of up to kilobits per second in bit definition and sampling rates of 96 kilohertz, the standard simply hasn't caught on. Not even after a few manufacturers partnered in September , including premium audio brands like Sennheiser, Audio-Technica, and Edifier, chipmaker Cirrus Logic and mobile phone maker Huawei.
However, this doesn't mean that Android devices or laptops don't also support the standard. While the technical side with kilobits per second at bit and 96 kilohertz don't sound particularly impressive, the quality of AAC is very interesting overall. This is because AAC's file transfer is based on psychoacoustic models that consider at the time of compression what people can hear.
Since this requires more processing power and power management works differently between Android and iOS, AAC provides better sound quality on your iPhone. For example, you can buy the Bose Noise Cancelling Headphones ! As the quality under Android depends on many factors, you should pay more attention to the previous codecs if you don't have or intend to buy an iPhone. Since Bluetooth 5. However, I would like to include it in this article as it is basically the successor to the SBC codec.
As Bluetooth. However, LC3 is not really widespread yet and is currently more of an interesting promise for audio geeks.
By submitting your email, you agree to the Terms of Use and Privacy Policy. But what exactly is a codec, and where does the term come from? While modern codecs are software-based, in the past hardware codecs were more common particularly when analog formats first started to be digitized. As an example, an MP3 codec is used to create MP3 files from audio data. In essence, a codec is used to encode data in a format that can be transmitted or stored and later viewed with a counterpart decoder.
In the world of video, H. While H. The common thread among all of the codecs mentioned in this article so far is that they are used for one purpose: compressing data.

This year, the successor to H. This codec was developed by Google as a royalty-free open-source codec. As you can see, there are a variety of codecs, all of them changing and evolving. While there are many newer and more efficient codecs, h. Author Gayane Sargsyan. What is a codec? VP9 This codec was developed by Google as a royalty-free open-source codec.
