![]() ![]() It has two main forms – ACL ( Asynchronous Connection-Less) and SCO ( Synchronous Connection Oriented). In order to understand Bluetooth audio codecs, it is important to know a few things about Bluetooth data transfer. It is expressed in kilobits/megabits per second (kbps/Mbps) and you can calculate it by multiplying sample rate, bit depth, and the number of channels. Bit rateīit rate represents the number of bits processed per each second of one audio file. The situation with bit depth value is the same as the situation with sample rate – the higher it is, the larger the audio file. If we take a CD-quality file as an example, we can say that it supports 16-bit and DVD-quality files, while Blu-ray discs usually support 24-bit audio files. It determines the resolution of an audio file and it’s expressed in bits. ![]() Bit depthīit depth represents the number of bits contained in one audio sample. In this case, high-res files are the files exported at the sample rate equivalent to 96 kHz or higher. High sample rate implies higher file resolution and size. It is expressed in hertz (Hz) and it represents the number of data points per second of an audio file. The sample rate is one of the most common words when it comes to audio files and Bluetooth audio codecs. This is the reason why low-res audio files can be stored in high amounts on your phone but high-res files require the storage space not smaller than a CD. Unfortunately, the compression results in lower audio quality. This requires high compression of your audio files because the Bluetooth connection is still not capable enough. The main purpose of any codec is to transmit quality signal at a certain bit rate. It encodes and decodes the digital audio signal into a specific format. Bluetooth audio codecĬodecs define the way Bluetooth signal is transmitted from a source (e.g. Key Terminologyīefore we proceed to the codec description, we will explain some of the keywords for understanding the whole story about Bluetooth audio codecs. Some common Bluetooth audio codecs include SBC, AAC, aptX, and LDAC. Different codecs offer varying levels of audio quality and efficiency, with some sacrificing audio quality for lower latency (the time it takes for the audio to be transmitted) and others prioritizing audio quality over latency. In order to help you get a better understanding of Bluetooth audio codecs, we have prepared this short article and tried to explain everything in simple and understandable words.īluetooth audio codecs are algorithms used to compress and decompress audio data when transmitted over a Bluetooth connection. This is the main reason why so many people make their decisions based on the product’s design and price. Even if they do, they certainly don’t explain the meaning of each term and most of us can’t really understand their meaning. Moreover, manufacturers of Bluetooth-enabled phones and headphones don’t always publish the complete specifications. Like it or not, you should get ready for the new Bluetooth era. The quality of Bluetooth can still be argued but it has become obvious that we can’t fight the future. ![]() Subsequently, Bluetooth technology is rapidly developing and improving, and it is probably going to replace the old way of listening to music. Considering the fact that we all live faster and that we are constantly “on the go”, the necessity to make everything light, portable and simpler is perfectly understandable. Apple was the first company to remove the headphone jack from their iPhone 7 and some other manufacturers did the same.ĭoes the lack of headphone jacks imply that we don’t need them anymore? Well, we’ll see about that later but the fact is that the modern world is all about convenience. We’ve had some doubts for a while but the increasing number of new smartphones without aux ports has reassured even the most suspicious ones. The main reason for discussing Bluetooth audio codecs is the fact that Bluetooth is the future of wireless headphones and earbuds.
