Although MP3 is one of the most widely used audio file formats, sometimes we need to convert audio files into other formats to enhance audio quality and reduce file size. The audio file formats, including MP3, AAC, MP4, FLAC, OGG, WAV etc, all offer a different audio quality and size combination, and it’s up to the user to select which file format they are most attracted to. This is where audio converters and encoders jump in, providing an easy solution for users to convert between different audio file formats. LameXP – Audio Encoder is an open source application that lets you convert audio files between a wide range of audio formats.
