Audio compression is the process of compressing audio files in order to make their size smaller with regards to the bytes contained. Compressing audio files uses lossy compression in which sound that is not heard by the human ear is removed from the file so the size will decrease without affecting the output. People will still hear the same sound that they heard before the compression as they were not able to hear parts that were removed in the first place.

There are several reasons why you may want to compress your audio files. As mentioned, a compressed audio file has a smaller size, which can save space on your computer or whatever device you are saving it to. It is also perfect for web use as it would be easier to stream the file online. If you wish to send it to another individual, this can be easily done by attaching it on an e-mail.

Top formats that you can choose to compress audio You can reduce the size of audio file by compressing it into different formats depending on your preference. However, mp3 is the best format as this is the standard audio format supported by most media players and devices. Another compression format that you can use is MP3PRO, which makes audio files even smaller and can be played on mp3 players. ACC has a smaller size and better quality than mp3. However, this is not commonly used as only few players support it. WMA is another format that you can use to compress audio.

It has lower bitrates, which is good for online streaming. ACS format can be played on different electronics such as cable TV and high definition TV. Factors related to audio file size There are different factors that are related to the size of an audio file. This includes codec and audio settings such as bit rate, channels and sample rate. Codec is the way that an audio file is compressed. This determines how small the size of the audio file is.

Bit rate is the quality of an audio file. Higher bit rate means better quality. However, this also means bigger size.

So if you want to reduce audio file size, one way is to lower the bit rate. The channel determines how audio travels from the source to the destination. For instance, a stereo source has two channels, while a mono source only has one channel. Sample rate refers to the number of samples of audios carried every second. Lower sample rate decreases size.
