Understanding wav and au file formats
WAV (Waveform Audio File Format) is a widely used uncompressed audio file format developed by Microsoft and IBM. It stores high-quality audio data and is commonly used for professional audio recording and editing. AU is an audio file format introduced by Sun Microsystems, primarily used on Unix systems and in early web applications. AU files can contain various encoding types, but are often used for simple, uncompressed audio.
Why convert wav to au?
