WAV vs MP3 for silence — which to use?

Use WAV when

+Professional audio/video editing (DAWs)
+Lossless quality is required
+Concatenating with other WAV files
+File size doesn't matter

Use MP3 when

+File size matters (MP3 is ~50x smaller)
+Web/app audio playback
+Silent ringtone or notification
+Email attachment size limits

Generate silence yourself

FFmpeg (any duration)

# 60 seconds of silence as WAV
ffmpeg -f lavfi -i anullsrc=r=44100:cl=stereo -t 60 silence-1min.wav

# 60 seconds of silence as MP3
ffmpeg -f lavfi -i anullsrc=r=44100:cl=stereo -t 60 -c:a libmp3lame -b:a 128k silence-1min.mp3

Python

import wave, struct

duration = 60  # seconds
sample_rate = 44100
with wave.open('silence.wav', 'w') as f:
    f.setnchannels(2)
    f.setsampwidth(2)
    f.setframerate(sample_rate)
    f.writeframes(b'\x00' * sample_rate * 4 * duration)

Frequently Asked Questions

Is this truly silent or does it contain background noise?

Truly silent — every sample is digital zero. No white noise, no hiss, no ambient sound. This is different from recording silence with a microphone, which always captures some noise. Our files are programmatically generated zeros.

Why would I need a 1-hour silence file?

Common uses: silent ringtone to mute specific contacts, testing long-running audio playback, padding in automated video rendering pipelines, and testing audio player memory usage over extended playback periods.

Can I use these as a silent ringtone?

Yes. Download the 1-second or 5-second MP3 and set it as a ringtone on your phone. This effectively mutes that contact/app without using Do Not Disturb mode.

Why is the WAV file so much larger than MP3?

WAV is uncompressed — 1 minute of stereo 44100Hz 16-bit audio is always ~10MB regardless of content. MP3 compression reduces silence to ~120KB for the same duration because silence compresses extremely well.

Will audio detection systems detect these as silence?

Yes. Voice Activity Detection (VAD) systems should classify these as silence since the amplitude is exactly zero. Use them to verify your VAD threshold settings and silence-detection algorithms.
