    Frequently asked questions

    AIFF is Apple's equivalent to Windows WAV — same uncompressed audio content, same quality, slightly different file structure. Today interchangeable in most software.

    AIFF stores each audio sample in clear (16 or 24-bit PCM). One minute of 44.1 kHz stereo music weighs ~10 MB. It's the historical raw format of audio CD and studio work.

    Yes, ALAC (Apple Lossless) compresses AIFF losslessly, typically 40-50% weight gain. Quality is bit-for-bit identical — you can go back to AIFF without loss anytime.

    Yes, AAC (lossy) reduces weight by ~90% with perceived quality very close for daily listening. Ideal for the personal iTunes/Apple Music library.

    Yes, AIFF is still heavily used in Mac studios (Logic Pro, Pro Tools) because it has no compression and thus no loss. The final mix is then exported to distribution formats (AAC, MP3, FLAC).
