Lossy audio

Lossy audio Definition - What is Lossy audio?

When audio is converted to digital formats such as MP3, WAV, etc., sometimes the audio is compressed in order to make the total file size of a particular piece smaller and more manageable. Compression is done by removing frequencies at the high and low end of a piece of audio. When these pieces are lost, the result is called lossy audio. This is in contrast to lossless formats, where the entire scope of a piece is digitized exactly, so that the digital version of a piece of audio is identical to the original recording.
