Cut AIFF

How to Cut an AIF File Online

1. Upload Your AIF File: Drag and drop, or click "Select File" to pick the audio from your computer. Both .aif and .aiff extensions are accepted — they are the same Audio Interchange File Format, just two different filename suffixes. Batch uploading multiple clips is supported.
2. Set Start Time and Duration: Enter the cut point in seconds (e.g., 12.5) or in HH:MM:SS.sss format (e.g., 00:00:12.500) for millisecond precision. The duration field controls how long the kept segment runs from the start point. Frame-accurate trims down to a single PCM sample frame are possible because the underlying SSND chunk is sliced losslessly.
3. Choose Output Format (Optional): Default keeps the file as AIF so the original 16-bit/24-bit big-endian PCM stream is preserved bit-for-bit. Switch to AIFF if you prefer the longer extension, AIFC for the compressed Apple variant, or hop over to Convert AIF to MP3 / Convert AIF to WAV if you also need a format change.
4. Cut and Download: Click "Cut". Each clip is processed in your browser session — no upload to a third-party server, no sign-up, no watermark — and downloaded individually or as a ZIP when you cut several files at once.

Why Cut AIF Files?

AIF is the 3-character variant of Apple's Audio Interchange File Format, kept around from the DOS-era 8.3 filename limit when extensions were capped at three letters. Both .aif and .aiff decode to identical PCM audio — same big-endian byte order, same COMM and SSND chunks, same uncompressed quality — so any tool that reads one reads the other. Cutting is the most common reason to open an AIF file: the format is uncompressed (≈10 MB per minute of 44.1 kHz / 16-bit stereo, per the AIFF spec), which makes full files unwieldy to keep when you only need a 15-second selection.

• Make an iPhone ringtone or text tone — Apple's GarageBand caps custom ringtones at 30 seconds and text tones at 40 seconds. Cut your AIF down to the chorus before importing so GarageBand doesn't auto-truncate the wrong section.
• Trim sample-library content for a DAW — Logic Pro, Pro Tools, Ableton Live, and Reaper all import AIF natively, but pulling a kick or vocal phrase from a 5-minute reference track loads the whole file into RAM. Cut once, drag the slice into your session.
• Pull a clip from a CDDA rip — Many CD-ripping workflows (iTunes/Apple Music's AIFF preset, Roxio Toast, dBpoweramp) produce one AIF per track. Cut a single quote, hook, or sound effect without converting away from lossless PCM.
• Shorten a podcast/voiceover bed — A 24-bit/48 kHz AIF master at ~14 MB per minute gets uploaded once but reused as 30-second promos. Trim each promo from the master in the browser instead of opening Adobe Audition.
• Prepare audio for video editors — Final Cut Pro and DaVinci Resolve prefer uncompressed AIF/WAV on the timeline. A cut AIF drops straight into the audio track at the exact length the edit needs.
• Slim down archived recordings — Field recorders (Zoom H4n/H6, Tascam DR series) often write AIF/WAV. Cutting silence and pre-roll before archiving can cut storage by 30-60% without re-encoding.

Cut Length Guide for Common Targets

Use case	Recommended length	Notes
iPhone ringtone (.m4r)	≤30 seconds	GarageBand auto-shortens longer clips
iPhone text tone	≤40 seconds	Same 40-second cap as ringtones
Sampler/drum slice	0.1-4 seconds	Cut at zero-crossing to avoid clicks
Podcast intro/outro bed	5-15 seconds	Keep the musical phrase intact
Social-media audiogram (Instagram, TikTok)	15-60 seconds	Match the target platform's clip cap
Voicemail greeting	≤20 seconds	Most carriers cap greetings around 20-30 seconds
DAW sample import	Variable	Trim leading silence so the sample triggers on hit

Frequently Asked Questions

Is .aif a different format from .aiff, or just a different extension?

Just a different extension. Both decode to the same Audio Interchange File Format spec Apple published in 1988 — identical big-endian PCM payload, same COMM chunk describing channels / bit depth / 80-bit IEEE sample rate, same SSND chunk holding the samples. The .aif form survives from the DOS 8.3 filename era when extensions were capped at three characters; modern macOS, Windows, and Linux read both interchangeably. Renaming clip.aif to clip.aiff (or vice versa) doesn't change a single byte of audio data.

Does cutting reduce audio quality?

No. When you keep the output as AIF (or AIFF), the cutter slices the SSND chunk at the sample boundary you set and rewrites the chunk headers — no decode, no re-encode, no requantization. The PCM samples in your output file are bit-identical to the corresponding range in the source. Quality only drops if you change format on the way out (e.g., AIF to MP3, which involves lossy MDCT encoding).

Can I cut down to the millisecond, or only to the second?

Down to a single PCM sample frame, which at 44.1 kHz is ~0.023 milliseconds. Enter cut points in HH:MM:SS.sss format (three decimal places) and the tool snaps to the nearest sample frame. For sub-frame precision you'd need to resample, which would re-encode.

Why is my AIF so much bigger than an MP3 of the same song?

AIF stores uncompressed PCM, so file size scales linearly with sample rate × bit depth × channels × duration. CD-quality stereo (44.1 kHz / 16-bit) is about 10 MB per minute per the AIFF spec, and 24-bit/96 kHz studio masters hit ~33 MB per minute. A 192 kbps MP3 of the same content is roughly 1.4 MB per minute — about 7× smaller — because MP3's lossy compression discards inaudible (and some audible) detail. If file size matters more than studio fidelity, Convert AIF to MP3 after cutting or use Compress AIF to shrink the PCM stream itself.

Will the cut AIF play on Windows without extra software?

Yes. Windows Media Player has shipped AIFF/AIF decoders since Windows 7, and the modern Films & TV / Groove apps decode them too. VLC, Audacity, foobar2000, and Winamp all play AIF natively. The only AIF variant that occasionally trips Windows is AIFC with an Apple-only codec like ALAC inside an AIFC container; standard PCM AIF (what comes out of this cutter when you keep the format) plays anywhere.

Can I cut multiple AIF files in one go?

Yes. Drop several files into the uploader and each one gets cut to the same start/duration you set, then delivered as a ZIP. If you need different cut points per file you can queue them one at a time — each cut runs locally in your browser session, so there's no per-file upload latency.

How do I make an iPhone ringtone from a cut AIF?

Cut the AIF to 30 seconds or less, then convert it to AAC in an .m4r container. The Apple Support workflow for GarageBand on Mac is: drag the AIF onto an audio track, trim to ≤30 seconds, then File → Share → Ringtone. On iPhone, GarageBand for iOS imports the trimmed AIF from iCloud Drive and exports as a ringtone, text tone, or contact alert. The 30-second cap is a hard limit — longer clips get auto-shortened by GarageBand or silently rejected by the Tones store.

What's the difference between cutting and trimming?

In casual usage they're synonyms, but conventionally: "trim" removes leading or trailing silence (the bookend), "cut" extracts a specific middle section by start + duration, and "split" breaks one file into multiple pieces at marker points. This tool does the start-plus-duration cut; for end-removal you can set the duration shorter than the file. For multi-segment work check the Audio Cutter which covers all three modes.

Should I cut as AIF, AIFF, AIFC, or convert to something else?

Keep AIF/AIFF when you're feeding the clip into a DAW, video editor, or any workflow that benefits from uncompressed PCM (no quality loss across multiple edits). Pick AIFC only if downstream tools specifically expect the compressed variant — most modern apps prefer FLAC or ALAC for lossless compression these days. Convert to MP3 or AAC for sharing / streaming, to M4R for iPhone ringtones, or to WAV via Convert AIF to WAV for maximum cross-platform compatibility (WAV is little-endian and slightly more universal on Windows).
