Frequently Asked Questions
- How do I make an MP3 louder without distortion?
- Keep the Anti-Distortion Limiter on (the default). It caps peaks just below full scale, so even a 300% boost stays clean — loud passages are gently held back instead of clipping into crackle.
- How much louder can I make an MP3?
- Up to 300% (3×). If a file is still too quiet at 300%, run it through a second pass — very quiet phone or dictaphone recordings sometimes need it.
- Does boosting re-encode the MP3?
- Yes — changing the audio signal requires re-encoding. The tool encodes at a high bitrate to keep the generation loss inaudible; pick WAV output if you want no lossy step at all.
