An MP3 file is an audio file that uses a compression algorithm to reduce the overall file size. It’s known as a “lossy” format because that compression is irreversible and some of the source’s original data is lost during the compression. It’s still possible to have fairly high quality MP3 music files, though. Compression is a common technique for all types of files, whether it be audio, video, or images to reduce the amount of storage they take up. While a 3-minute lossless file, such as Waveform Audio file (WAV), can be around 30 MB in size, the same file as a compressed MP3 would only be around 3 MB. That’s a 90% compression that retains near CD quality!) Steps for converting MP3 to AU using the MediaShare online convert free are enlisted below.
