If makeup gain then raises the entire processed signal, that front edge may reach a higher absolute peak than it did before compression. The transient may also *feel* more pronounced because its level relative to the sustain has changed. These are different outcomes, and neither means a compressor always raises peaks. ## Key takeaways - Finite attack can let a short initial peak pass before full gain reduction develops. - Post-compression makeup gain can lift that surviving peak above its original absolute level. - More perceived punch does not necessarily mean a higher sample or true peak. - A gain-reduction meter alone does not prove that the output peak is lower. ## Follow one drum hit through the envelope At the first edge of a snare, the detector recognizes a rising level and requests reduction. With nonzero attack, the gain element approaches its target over time. Some of the initial front edge can pass while the later body receives more attenuation. The resulting attack-to-body contrast can sound snappier even if the very first peak stays at about its old level. Now add post-compression makeup gain to restore average or perceived level. It raises the surviving front edge along with the attenuated body. The output meter can show a higher peak than bypass, despite the compressor showing reduction during the tail. FabFilter's time-control documentation distinguishes wet gain, attack behavior, and dry gain, illustrating why these stages must be considered separately. ## Separate impact from peak height Punch is a listening judgment shaped by attack, body, spectrum, groove, and playback level. A drum can feel more immediate because its body receded, even if the absolute transient peak did not increase. Conversely, a makeup boost can increase the numerical peak without making the hit feel better. The [peak-control-versus-loudness article](https://gawergy.com/learn/peak-control-vs-loudness) addresses a related measurement-versus-perception gap. A dry/wet compressor blend can also bring back the original transient while the compressed path adds density. The two paths sum, so alignment and relative level affect the combined peak. This is a routing and summation issue as much as a compression one. Watch the meter *after* the blend and any output gain. ## When compression really does lower the transient Fast attack, appropriate peak detection, lookahead, or an already-active gain envelope can reduce a peak's front edge. On a dense pattern, the previous hit's release may leave gain reduction in place when the next hit arrives. A high threshold may do nothing at all. The compressor cannot be characterized by ratio alone; attack, detector, release, threshold, and previous signal history all matter. This is also why comparing one isolated kick with a full drum pattern can be misleading. The control state entering each hit differs. Listen to the intended musical passage and measure the processed output over the same interval. Do not infer absolute peak reduction from how much the gain-reduction meter moved at a different moment. ## Verify what became louder First level-match the processed and bypassed versions so a simple gain difference does not dominate. Then compare the front edge, body, and tail in context. Read a sample or true-peak meter after compression to check the absolute ceiling question, and use the compressor's trace to understand timing. If the new peak is unwanted, reducing makeup gain may solve it without sacrificing the envelope change. If the goal is to restrain a small set of exceptional hits, clip gain or automation may be more direct than forcing the entire bus through heavier compression. If deliberate peak reshaping is wanted, a clipper changes the waveform by a different mechanism. G-Clipper Pro is one optional visual tool for inspecting that tradeoff, not a required part of the compression workflow. ## About G-Clipper Pro G-Clipper Pro is made by Gawergy Audio. This product note is separate from the educational guidance above. If compression leaves a few peaks that need deliberate waveform shaping, G-Clipper Pro can help show which peaks are altered. It is not a replacement for understanding the compressor's gain envelope or measuring the final output.
