A codec is an algorithm for encoding and compressing data in an audio format. Some file types are assigned a specific codec. For example, the MP3 format always uses the MPEG Layer-3 codec, while the MP4 format can use a range of different codecs.<\/p>\n

Many times, the notions of codec and format are used as interchangeable. Especially when a format always uses a single codec. However, it is necessary to understand the difference between a format and a codec. In simple terms, a format can be compared to a container in which a sound or a video signal that uses a particular codec can be stored.<\/p>\n

Some formats, such as MP4 or FLV, can store both audio and video sequences.<\/p>\n

If you don’t know what program you should use to open one format or another audio, we recommend that you use our audio converter. It is compatible with almost all existing formats.<\/p>\n

Depending on the type of compression, two types of codecs can be distinguished:<\/p>\n
