A PRACTICAL AUDIO GUIDE
ChatGPT AIFF Editor: Cut and Fade AIFF Audio
For an AIFF recording, a simple timed instruction can be enough. Make a cleaner opening, a shorter excerpt or a natural ending without starting with a complex timeline.
Upload audio and start editingBring in a useful section of the recording
AIFF files commonly contain uncompressed PCM audio and can be large. Upload .aiff or .aif directly, within the 100 MB limit. If a recording is too large, export a shorter passage from the source recorder before uploading it. Decoded memory and device capacity also affect what can be opened.
Make boundaries that respect the performance
For a spoken take, name the time before the first full word. For music, leave the attack of the first note intact and allow the last sound to decay. A prompt such as “keep 0:08 to 0:38, with a gentle fade at the end” gives you a clear excerpt to check.
Use versions for alternate cuts
After the first edit, open History to return to the original and try a different start or ending. You can compare a tight excerpt with one that has more room without overwriting the original file on your device. Download the version that fits the intended use.
Keep the source when handing audio to another editor
AIFF export uses 16-bit PCM. It is useful for everyday playback and further editing, but does not preserve every field from a high-resolution or professionally tagged source. Keep the original if bit depth, markers or metadata are part of the handoff. WAV and FLAC are also available for the edited copy.
A prompt to try
Keep 0:08 to 0:38. Add a half-second fade in and a 2-second fade out, without changing pitch or tone.
Check the first attack and final tail. The excerpt should last 30 seconds after the edit.
Common questions
Are AIF and AIFF both accepted?
Yes. The editor accepts .aif and .aiff files where their audio codec can be decoded.
Does the download preserve a 24-bit AIFF source?
The current AIFF download uses 16-bit PCM. Retain the source if its original resolution or metadata is required.
