AIFF Audio
AudioAIF is the shorter AIFF audio suffix, unrelated to AI artwork. Inspect codec, rate and bit depth in audio software rather than renaming to WAV. For legacy production files, check AIFF-C variants and verify duration/channels after import.

Troubleshooting by symptom
- Speed/pitch changes: inspect sample-rate interpretation and import conversion.
- AIFC fails: inspect compressed-codec support.
- Different export sound: check bit-depth changes, gain, dither and channels.
- Only noise: check that a headered AIF was not imported as raw audio.
- Wrong speed: compare playback settings and the file sample rate.
- Some AIF files fail: check AIFF-C or other encoding support.
AIFF → PCM WAV / FLAC
- Record codec, rate and bit depth, then import.
- Export a separate copy at the required precision and compare duration, samples/channels.
- Play the exported audio in another application and check the ending.
Gain/rate changes alter samples; equivalent audio does not guarantee retained tags/markers.
Distinguish AIF, AIFF and AIFF-C
The suffix alone does not settle whether the file uses PCM or a variant encoding. Inspect the reported codec when import fails.
Guessing raw-import parameters can produce noise or wrong speed; prefer normal file import.

What to compare after export
Project saving and audio export serve different purposes; deliver a playable audio file.
Changing depth or rate involves conversion. Compare duration, leading silence, peaks and channels and retain the source.

| Format | Main role | What to check |
|---|---|---|
| AIF / AIFF | Audio file | Check encoding/rate |
| WAV | Audio interchange | Output encoding settings |
| MP3 | Compact distribution | Lossy compression |
Handling and security
Review recording rights/private speech and edit a copy.
Questions and answers
Are AIF and AIFF different?
Usually alternative suffixes; still inspect encoding.
Always uncompressed PCM?
Inspect the encoding, including AIFF-C variants.
Is WAV export always unchanged?
It depends on precision, rate, processing and metadata.
Does renaming AIF to AIFF degrade audio?
Renaming does not recompress audio, but cannot resolve unsupported encoding.
Does converting MP3 to AIF improve quality?
It can create an editing copy, but cannot restore information lost in MP3 encoding.
