AAC stands for Advanced Audio Codec , and is one of the most normally supported Bluetooth codecs in the audio frequency market . Here is what you need to know about it .
The world of audio is vast , and it can sometimes get a trivial consuming if you ’re examine to learn more about the audio codecs used on various devices . Thankfully , we ’re here to break down one of the most commonly used codecs and explicate where it crops up in most , as well as its benefits .
Keep read to find out everything you require to know about AAC .
What is AAC?
AAC stands for Advanced Audio Codec , and is an audio coding standard used to compress and encode digital audio file cabinet . It was designed to be the successor to MP3 and claims to provide better audio caliber .
It can be used to write in code audio files at culture medium to high-pitched turn rates , with the melodic theme that it minimises the amount of data required for high - timbre digital audio . Anything that is not needed , such as signal constituent and redundance is dispatch to shrivel up the file to a size that ’s more achievable .
Advanced Audio Codec is equal to of sample frequencies from 8Hz to 96kHZ as well as up to 48 channels , with the added benefits of compress complex audio is a much easier way than MP3 can .
Who uses AAC?
Moreover , as well as being an audio format , AAC is also the default sound recording compressed method acting that is used by both Google ’s YouTube as well as Apple ’s iTunes .
AAC is supported on both Apple and Android devices , however , it ’s claimed to perform better on Apple twist than Android due to the hardware encoders on iOS devices seem more able to process it expeditiously , using a more advanced compression algorithm that can well handle AAC .
Plus , AAC is a much heavier codification on the processor than some other formats , meaning smartphones that prioritise efficiency over functioning wo n’t get the full benefits of AAC , as it will be encoded at a low-pitched mo - rate to save power . This contributes to why Android phones , like thePixel 6 Pro andSamsung Galaxy Note 8 , will probably see less impressive performance from AAC than Apple sound like theiPhone 13 Pro Max .
It is also utilised by myriad other companies , include the likes of Dolby , Sony and Fraunhofer IIS as a better solution to MP3 .
Is the audio quality good?
As we ’ve just covered , the audio quality of AAC may vary bet on the gimmick . Anyone who is n’t using an Apple equipment and AAC can potentially expect audio frequency to sound less telling , with minor details being lose .
However , it does n’t go as expert as lossless CD - quality audio ( although Apple will claim there ’s virtually no difference between AAC and lossless ) , though it is considered to be better than the received Bluetooth SBC ( Sub - Band Coding ) codec . This should n’t be too much of a job for most consumers , but if you opt to listen to euphony in high timber then AAC has its limitations .
Most headphones stand AAC encryption , but it ’s not unusual for inexpensive earpiece to jump AAC altogether . If that ’s the case then any earphone that does n’t support AAC then your twist will default to SBC . As Io devices pip a soap of AAC for Bluetooth audio cyclosis , you should twice mark off your headphone ’s support to get the best audio quality .
And as it is widely supported by various devices and software political platform , a list that includes iOS , Android , Windows , macOS and Linux , it is very accessible .
We would n’t say AAC has the best audio lineament , but for iOS and Android devices , its ability to compress the sizing of filing cabinet makes for a commodious manner to stream music .
