About Audio Diff
Compare two audio files online in the browser and review whether they match. MKDiff Audio Diff analyzes waveform shape, duration, loudness, peak level, clipping, silence, spectral energy changes, offset alignment, and high-difference time segments so reviewers can jump directly to the parts that changed.
Common Uses
- Compare voiceover, podcast, music, or sound-effect revisions before approval.
- Check exported audio against a source file after editing or conversion.
- Align files with small timing offsets before judging waveform or spectral differences.
- Find the time ranges where two audio files sound most different.
- Review waveform, spectral, loudness, peak, silence, and clipping changes without installing desktop software.
FAQ
Can I compare two MP3 files online?
Yes. Upload two MP3 files and MKDiff analyzes waveform, duration, loudness, sample rate, spectral differences, and similarity in your browser.
Can I compare two voice recordings?
Yes. MKDiff can compare voice recordings and show whether timing, loudness, waveform shape, and spectral energy are close or different.
What does Audio Diff compare?
It compares duration, waveform frames, loudness, peak volume, clipping, silence, spectral energy bands, offset alignment, and the strongest difference moments.
Can I jump to the changed audio segments?
Yes. The heatmap and difference segment list let you jump playback to the time ranges with the largest detected changes.
Can Audio Diff export the difference between two files?
Yes. After analysis you can export a difference WAV that subtracts the aligned modified audio from the original audio.
Are my audio files uploaded?
No. Audio Diff is designed for browser-side analysis, so selected audio files can be decoded and compared on your device.
Compare two voice recordings—not speaker identity
This free voice comparison workflow measures differences between two recordings: timing, waveform, loudness, spectral energy, silence, and clipping. It can show how similar the files are, but it does not authenticate a person or prove that both recordings contain the same speaker.
- Useful for voiceover revisions, podcast edits, and recording quality checks.
- Jump to the strongest changed segments instead of replaying the entire file.
- Files are decoded and analyzed locally in the browser.
