We listen to music very often. Likewise image file formats and video file formats audio also has a file format which makes it identify. You are very familiar with the MP3 file format but there are also many other formats. Now keep on reading this as you will get to know about various audio formats till the end of this post.
First of all the most popular ones like the.MP3,.AAC,.OGG store audio using lossy compression. The raw audio files contain some information that is so low volumed or very high pitched.
In Lossy compression, these parts get deleted. They don't affect the audio much. They also save space by using a different bit rate as whenever audio is recorded digitally, the system stores the audio as digital bits (0,1). It is said that an uncompressed audio file has a bitrate of 1411 kilobits per second (KBPS). This KBPS is kilobits per second which denotes the quality of the audio file which is called the bit rate.
And by removing the unwanted parts it makes the size of the file very small. MP3 is used by most users but others such as.AAC converts high-quality audio into a lower bitrate. .OOG is an open-source format. It is nowadays heard that MP3 file format is used no more and this is being replaced by AAC (Advanced Audio Codec).
Some formats use lossless compression to contain audio. They provide high-quality sound and quality. Those file formats are -.FLAC and.ALAC. They contain the whole original audio. They also have a smaller size. The original data may contain some repetitive information and may some unique information. It predicts the next occurrence of information by sensing the repetitive data and the difference between them. The codecs used here only store the difference between the predicted data and the original file. These codecs compress in such a way that they are half of the size of the actual file.

.ALAC is a file format used in iTunes, There are other codecs for lossless compression such as Dolby True HD and DTS HD Master Audio used in home theaters and blu-rays. Dolby Atmos is another codec that can be used to make audios that can be listened through various speakers.
But there are also some advantages in storing audio files uncompressed such as.WAV and.AIFF. They are compatible with many devices. They contain all the information recorded or collected by converting the original audio from analog to digital. They are mostly preferred by audio editors to tune the original record.

So this is all the knowledge I had. It is not copied knowledge, it's my knowledge that's why it is called AnupKnowledge.
