Make audio louder with evidence, not a mystery percentage
A decibel gain is converted to a linear sample multiplier, while peak-normalize and RMS-target modes calculate their own gain from the decoded signal. Before and after peak, RMS, crest factor and clipping counts stay visible.
Three useful gain workflows
Use manual gain when you know the adjustment, peak normalization when you want a deterministic sample-peak ceiling, or RMS target when arithmetic signal energy is the comparison you need. RMS is deliberately not labeled LUFS.
Limiter choices stay explicit
Soft ceiling, hard ceiling and no-limiter modes expose how many samples crossed the target before protection. That makes the tradeoff inspectable instead of hiding a limiter behind a generic “enhance” button.
Private local export
The processed result can be previewed beside the original and exported as 16-bit PCM or 32-bit float WAV. Audit CSV and Project JSON hold settings and numeric evidence; they do not embed the source audio.
When another audio tool is better
Use a loudness analyzer for LUFS-style measurement, an equalizer for frequency balance, a compressor for dynamic range, or a clipping detector when diagnosis rather than gain change is the primary task.
