2. Set trim points — Under "Trim," enter a start time and duration.
3. Adjust compression (optional) — Under "File Compression," select "Quality Preset" (Highest to Lowest) or "Constant Bitrate" for fixed bitrate output.
4. Set audio channel (optional) — Under "Audio Channel," choose mono or stereo.
5. Set sample rate (optional) — Under "Audio Sample Rate," select the output sample rate.
6. Trim and download — Click "Trim" and download your trimmed AIFF file.

Why Trim AIFF Files?

AIFF (Audio Interchange File Format) is Apple's uncompressed audio format — the Mac equivalent of WAV. Used in professional music production (Logic Pro, GarageBand), CD ripping on Mac, and audio archival. AIFF files are lossless but large — a 3-minute stereo track at 44.1 kHz/16-bit is about 30 MB.

Trimming AIFF files lets you extract specific sections from studio recordings, isolate samples for music production, remove silence from the beginning or end, or shorten files before importing into a DAW.

AIFF vs WAV vs FLAC

Format	Compression	Quality	File Size (3 min stereo)	Platform
AIFF	None	Lossless	~30 MB	Mac/Apple
WAV	None	Lossless	~30 MB	Windows
FLAC	Lossless	Lossless	~15 MB	Cross-platform
ALAC	Lossless	Lossless	~15 MB	Apple

Frequently Asked Questions

Can I upload both AIFF and AIF files?

Yes. Both .aiff and .aif are accepted — they're the same format with different extensions.

What compression setting should I use?

"Quality Preset: Highest" preserves maximum quality for studio work. For general use, "High" is sufficient. "Constant Bitrate" at 256–320 kbps for lossy output.

Should I use mono or stereo?

Keep stereo for music and studio recordings. Mono for voice-only content — halves file size.

Can I change the sample rate?

Yes. Under "Audio Sample Rate," select the output rate. 44100 Hz is CD standard. 48000 Hz for video audio. 96000 Hz for high-resolution audio.

Should I trim as AIFF or convert to FLAC?

For Mac-based production (Logic Pro, GarageBand), keep AIFF. For cross-platform lossless archival, AIFF to FLAC gives ~50% smaller files with no quality loss.
