Tip: pushing quiet audio past 100% can reveal background hiss. For best results, keep the boost moderate.
Upload an audio file, set the volume from 0% to 300%, and render a new WAV file. Handy for quiet recordings that need a boost.

Your audio file is decoded into raw sound samples, played through a digital gain stage set to your chosen percentage, and re-rendered into a brand-new audio buffer. That buffer is then encoded as a standard 16-bit WAV file you can download and use anywhere.
WAV is uncompressed, so the volume change is the only alteration: no re-encoding artifacts on top. The trade-off is file size, which is larger than MP3, but for a one-time volume fix the fidelity is worth it.
