M4A to WAV: Convert Audio from M4A(MPEG-4 Audio) to WAV(Waveform) with River Past Audio Converter, M4A2WAV converter, conversion

What is M4A?

Because of its exceptional performance and quality, Advanced Audio Coding (AAC) is at the core of the MPEG-4, 3GPP and 3GPP2 specifications and is the audio codec of choice for Internet, wireless and digital broadcast arenas. AAC provides audio encoding that compresses much more efficiently than older formats, such as MP3, yet delivers quality rivaling that of uncompressed CD audio.

To convert MPEG-4 audio to other formats, you need to have Apple QuickTime installed.

What is WAV?

The format for storing sound in files developed jointly by Microsoft and IBM. Support for WAV files was built into Windows 95 making it the de facto standard for sound on PCs. WAV sound files end with a.wav extension and can be played by nearly all Windows applications that support sound.
