Ever come across an AU file and scratched your head? AU, short for Audio, is a simple audio format from the early days of computing, born in the labs of Sun Microsystems. It’s like that old mixtape you found in your attic—charming but not exactly Spotify-ready. With 8-bit or 16-bit depth, AU files were used in early Unix systems and Java apps, offering raw, uncompressed sound. They’re lightweight but lack the polish of modern formats, and most devices today give them the cold shoulder. You’ll spot them in vintage software or retro archives, but to enjoy them now, conversion is the way to go.

AIFF, or Audio Interchange File Format, is Apple’s answer to high-quality audio. Think of it as a crisp, uncompressed snapshot of sound, perfect for music production or archiving. Developed in the late ‘80s, AIFF stores audio in a lossless format, keeping every detail intact, which makes files bigger but pristine. It’s a favorite in professional audio circles, especially for Mac users working in Logic Pro or GarageBand. AIFF plays nice with most modern devices and software, offering a balance of quality and compatibility. It’s like choosing a high-res photo over a compressed JPEG—when quality matters, AIFF shines.

Turning AU into AIFF is easier than brewing your morning coffee. Fire up a reliable tool like our online converter at runconvert.com or software like Audacity for more control. Upload your AU file, select AIFF as the output, and hit convert—it’s that quick. You can tweak bit depth if you’re feeling fancy, but defaults work fine for most. In seconds, you’ll have an AIFF file ready for your Mac, studio, or media player. Online converters are perfect for a quick job; just drag, drop, and download. Want to batch process or edit?

AU and AIFF are like night and day. AU, a bare-bones format from Sun Microsystems, is compact but dated, with limited device support. AIFF, Apple’s lossless gem, delivers studio-quality audio but with bigger files. AU’s fine for retro Unix fans or basic sound clips; AIFF is the go-to for music production and Mac ecosystems. AU’s raw structure lacks flexibility, while AIFF’s uncompressed format ensures every note shines. If you’re choosing for modern use, AIFF’s compatibility wins hands-down. It’s like picking a classic car versus a sleek electric—both have charm, but one fits today’s roads better.

AU and AIFF differ in their DNA. AU, with its 8-bit or 16-bit raw audio, is simple but lacks modern finesse, often sounding flat. AIFF’s lossless PCM format captures every detail, offering richer sound at the cost of larger files. AU’s minimal headers make it lightweight but tricky for some players; AIFF’s structured format ensures broad compatibility, especially on Apple devices. Neither supports advanced metadata, but AIFF’s quality edges out for pro use. The chart below breaks down their technical specs to help you choose wisely.
