For example, the compression cuts the sound frequencies that are inaudible for a human ear. When compressed with losses a sound undergoes certain modifications. The most common lossless encoding formats are: This group of formats records and compresses a sound in such a way as to allow preserving its exact original quality when decoding. It supports almost all the formats out there.ĭepending on the type of compression, two types of codecs can be distinguished: Lossless Codecs If you do not know what program should be used to open one audio format or another, we recommend using our audio converter. Some formats, such as MP4 or FLV can store both audio and video streams. In simple terms, a format can be compared to a container in which a sound or a video signal can be stored using a particular codec. However, it is necessary to understand the difference between a format and a codec. Especially when a format always uses a single codec. Often times the notions of codec and format are used as interchangeable. For example, the MP3 format always uses the MPEG Layer-3 codec while the MP4 format can use a range of different codecs.
For some file types, there is a specific codec assigned. wma).Ī codec is an algorithm for encoding and compressing data into an audio format. The format type usually corresponds to the file extension (the letters in the file name after the dot, for example. The most common of them are such formats as MP3 (MPEG-2 Audio Layer III) and WAV. There are plenty of audio formats out there.
