Frequently Asked Questions
What is AIFF format?
AIFF (Audio Interchange File Format) is Apple's uncompressed audio format, similar to WAV but with big-endian byte order. It's widely used in professional audio production on Mac.
How is AIFF different from WAV?
AIFF and WAV are both uncompressed formats with similar quality. AIFF uses big-endian encoding and is preferred on Mac, while WAV uses little-endian and is more common on Windows.
What bit depth should I use?
16-bit provides CD-quality audio and is suitable for most uses. 24-bit offers greater dynamic range and is preferred for professional music production and mastering.
Are AIFF files large?
Yes, AIFF files are uncompressed and quite large - typically 5-10x larger than compressed formats like AAC or MP3. This is the tradeoff for perfect audio quality.
Can Windows play AIFF files?
Yes, most modern media players on Windows support AIFF, though it's more commonly used on Mac. For better Windows compatibility, consider WAV instead.
