Shave the peaks. Hear what you cut.
Peaks are what stop a drum bus or a master from getting louder. Fault shaves them off, from a hard clip to a soft one, with oversampling to keep it clean, and a button that plays only what it took away.

Fault in 5 parts.
Hard to soft
SHAPE slides the clip from a hard corner to a gentle knee, so the same plugin does a drum bus shave and a soft saturation.
Drive and clip level
DRIVE pushes into the clip and CLIP LEVEL sets where it bites, from -12 to 0 dBFS. OUTPUT sets what leaves.
Oversampling
1x, 2x, 4x or 8x keeps the clipping from folding back as harshness. The latency stays the same, 40 samples, at every setting.
Hear what it removed
HEAR REMOVED plays only what the clipper cut off, so you hear the damage you are doing before you commit to it. The display shows it too.
Match and Link
MATCH stops the output being louder than the input, so you judge the sound and not the volume. LINK clips both channels together so a hit keeps its place in the stereo field.
- Measured. On a hard test (a 7 kHz tone, hard clip, +9 dB of drive), the distortion that folds back is 26.8 dB under the tone with no oversampling, 40.9 dB at 2x, 51.3 dB at 4x and 64.4 dB at 8x.
- Not a hard ceiling. After the oversampling filter, deeply clipped noisy material can read up to about 3 dB over the clip level in our tests. Put a limiter after it if you need a guaranteed peak.
- Transparent below the clip level. A quiet sine comes out the same, delayed 40 samples, with the error more than 70 dB down.
- Light on CPU. About 1.2% of one core at 4x and 2.1% at 8x in our test.
- Licensed, no trial. It stays silent until you enter the license key from your purchase email. 14-day refunds, no questions asked.
- Not part of the Nu series. It is a separate release with its own look.
