Two tools, one workflow. WaxOn prepares raw recordings for editing. WaxOff delivers your finished mix to broadcast standard.
macOS 14 Sonoma or later · Apple Silicon & Intel
Drop in raw recordings before editing. Optional ML noise reduction, high-pass filtering, loudness normalization, phase rotation, and brick-wall limiting — all in one pass.
Run your finished, edited mix through WaxOff for broadcast-standard loudness normalization and MP3 encoding.
Use WaxOn on raw recordings before you edit. Drop your files in, configure what you care about, and get to work.
Configurable cutoff from 20 to 90 Hz. Removes rumble, HVAC hum, and handling noise. Set to 20 Hz for DC block only.
Optional RNNoise ML noise suppression — a recurrent neural network trained on speech. Reduces steady background noise before any other processing. Off by default.
Optional two-pass EBU R128 with configurable target (−35 to −16 LUFS). Linear gain only — dynamics fully preserved.
2× oversampled true peak control at your chosen ceiling (−1 to −3 dB). Keeps transients honest.
200 Hz allpass reduces peak asymmetry and improves limiter headroom on voice recordings.
Select 2+ files and combine them. When loudness norm is on, each file is individually leveled before mixing, then the combined output is normalized — ensuring a balanced blend.
Five built-in presets plus custom presets. Up to 3 concurrent jobs with per-file progress.
Output: {name}-{rate}waxon-{limit}.wav · 24-bit WAV
Run your finished, edited mix through WaxOff. Broadcast-standard loudness normalization, true peak control, and MP3 output.
Two-pass analysis plus linear gain. No dynamic processing — stereo image and transients are completely unchanged.
Configurable ceiling from −3.0 to −0.1 dBTP (default −1.0). Compliant with podcast platform requirements.
24-bit WAV, CBR MP3 at 128, 160, or 192 kbps, or both simultaneously. Deliver exactly what your platform needs.
Optional 150 Hz allpass to reduce crest factor on bass-heavy material before final delivery.
Output: {name}-lev-{target}LUFS.wav / .mp3
WaxOn and WaxOff are two stages of the same pipeline — raw prep before editing, delivery prep after.
Supported formats: WAV, AIFF, AIF, MP3, FLAC, M4A, OGG, Opus, CAF, WMA, AAC, MP4, MOV. FFmpeg is bundled — no separate installation required.
