FREE TOOL · LOCAL DSP

Clean audio

Normalize a local recording safely, compare the original and processed audio at the same duration, and download a real WAV. Denoising is not silently substituted for normalization.

Choose audioPeak target (dBFS)The target is capped at 0 dBFS and processing never exceeds 8× gain.

A/B review

Choose an audio file and run the workflow to compare the original against the real exported WAV.

Listen at matched volume before deciding whether the result is better. Silence is preserved, stereo channels are retained, and the original remains available for comparison.
