Frequently Asked Questions
Will boosting cause distortion or clipping?
High gain levels can cause clipping if the original audio is already near peak volume. If you hear distortion, reduce the boost level. The tool applies gain as-is without a limiter.
Which audio formats are supported?
You can upload MP3, WAV, M4A, OGG, and AAC files. The output is a WAV file regardless of the input format.
What is the maximum boost available?
The slider goes up to 5x gain (roughly +14 dB). For subtle loudness increases, values between 1.5x and 2x are usually sufficient.
Is my audio sent to a server?
No. All processing runs in your browser using the Web Audio API. Your audio file never leaves your device.
