Frequently Asked Questions

How do I set a silent ringtone on iPhone?

Download the M4R preset, then transfer it to your iPhone via iTunes/Finder or AirDrop. Go to Settings → Sounds & Haptics → Ringtone and select the silent file. On iOS 17+, you can save M4R files directly from Safari.

What is the difference between pure silence and comfort noise?

Pure silence is absolute digital zero — no sound at all. Comfort noise adds very low-level pink noise (around -60 dBFS) that prevents the jarring \"dead air\" feel. Professional VoIP systems use comfort noise (RFC 3389) because complete silence can feel unnatural.

Why would I need a silent audio file?

Common uses: silent ringtones to mute specific callers, podcast spacers between segments, track separators in playlists, blank audio for video editing, calibration files for audio testing, and long silence tracks for sleep playlists.

What format should I choose?

For iPhone ringtones, use M4R (max 30 seconds). For Android, use MP3. For professional audio, use WAV or FLAC (lossless). For general use, MP3 or AAC offer the smallest file sizes.

Is the audio truly silent?

Yes. Pure silence mode generates all audio samples as zero — mathematically perfect digital silence. No noise floor, no artifacts, no encoding noise.

Can I create very long files?

Yes, up to 10 hours for lossy formats (MP3, AAC, OGG). Lossless WAV is capped at 60 minutes due to file size limits. The tool uses an efficient looping technique for long files.
