FAQ
How many dB is twice as loud?
+6 dB doubles the amplitude. A change of about +10 dB sounds roughly twice as loud to most listeners.
Will boosting clip the file?
Samples are clamped at full scale, so heavy boosts can clip. Use the normalizer if you want to hit a target peak without clipping.
Is it free?
Yes, free forever.
