Frequently Asked Questions
What is peak volume normalization?
Peak normalization scans an entire audio waveform to find the loudest sample, then applies a uniform gain multiplier so the highest peak matches the desired target level (e.g. -1 dBFS) without introducing clipping.
Is my audio uploaded to any server?
No! All decoding, peak detection, and gain scaling happens entirely inside your browser using the HTML5 Web Audio API.
What format is the downloaded file?
The normalized audio is rendered as uncompressed 16-bit PCM WAV at the original sample rate, preserving full fidelity.
