AU Audio is best described as sun/unix audio format for basic audio on unix systems, primarily serving Unix system sounds, telephony and basic audio processing. WAV Audio takes over where AU Audio falls short: mathematically perfect audio quality with zero compression artifacts. This conversion bridges two ecosystems: Sun Microsystems's AU Audio and Microsoft/IBM's WAV Audio. Xonvert supports batch conversion — convert multiple files at once and download them all as a ZIP.
Why Choose WAV Format for Your AU Files?
There are strong reasons to convert AU to WAV:
Quality preservation: Converting from AU Audio to WAV Audio maintains bit-perfect quality with no data loss.
Hardware acceleration: WAV Audio benefits from hardware-accelerated decoding on most modern devices, ensuring smooth playback and rendering.
Web optimization: WAV Audio is better suited for web delivery, loading faster and using less bandwidth than AU Audio.
Streaming support: WAV Audio is well-suited for streaming and progressive loading, making it ideal for web and mobile delivery.
Platform requirements: Many platforms and services specifically require WAV Audio format, making this conversion essential for submissions and uploads.
