How to use it

  1. Choose one supported audio file or try the synthetic stereo example.
  2. Set manual gain or a sample-peak target and inspect both channel waveforms.
  3. Create the WAV, listen to the verified output and download it.

Example: a signal peaking at −12 dBFS needs +6 dB gain to reach −6 dBFS. Both stereo channels receive that same gain.

Details & limits

Audio up to 20 MiB / 60 seconds; one mono/stereo track at 8–96 kHz. Gain −24 to +24 dB; peak target −12 to 0 dBFS. PCM 16-bit WAV output. Browser-supported codecs only; not LUFS or true-peak normalization.

Does peak normalization make different recordings sound equally loud?

No. Recordings with the same sample peak can have different perceived loudness. This is not LUFS matching, noise removal or compression. Output uses PCM 16-bit WAV; artwork and source metadata are not copied.

Change level without concealing clipping

A quiet recording can need more gain before it is shared or added to a presentation. Manual gain scales every sample equally, including background noise. Peak normalization instead calculates one gain from the highest absolute sample value, applying it to both stereo channels to preserve their balance. Settings that would exceed full scale are blocked instead of silently clipping the result. A sample peak does not measure perceived loudness or peaks between samples, so this tool makes no LUFS or true-peak claim. The waveform is a visual summary; listen to the actual exported audio as well.
