Limiter Types
Peak limiting, clipping and multiband limiting solve different problems, and swapping them shows up first in the attack.

Use a clipper as a limiter and the drums lose their attack first. Use a limiter as a clipper and loudness always falls short. Both carry the same name and do different jobs.
Four common types
| Type | How it works | Sound | Typical use | Risk |
|---|---|---|---|---|
| Brickwall limiter | Lookahead plus smoothed gain | Clean, may pump | End of delivery chain | Release too short |
| Clipper | Shaves the spikes directly | Dense, hard edges | Drums and electronic | High-frequency aliasing |
| Multiband limiter | Limits each band separately | Steady lows, less high-end work | Bass-heavy material | Phase at crossovers |
| True-peak limiter | Oversampled peak detection | No clipping after encoding | Lossy delivery | Latency and oversampling |
The choice follows delivery
With a high loudness target and synth-led material, clipping plus limiting is more efficient. With acoustic instruments and dynamics that carry the music, a brickwall limiter is steadier. When the low end is heavy and the mids are thin, multiband limiting can work only on the bass. For streaming delivery, true-peak detection must be on, with the ceiling near −1 dBTP.
Reading the controls by ear
Longer lookahead flattens transients more; shorter release makes low-end pumping clearer. Add 1–3 dB of drive at a time, then switch type rather than push further. When switching type, reset gain and match loudness again, otherwise the comparison is only about level. Oversampling in a clipper reduces aliasing and adds latency. A true-peak meter reads above the sample peak, so do not treat the two as the same number.
Limits and failure modes
A limiter cannot repair dynamic imbalance in the mix. A clipper placed after the limiter cuts the smoothed gain hard again. With two limiters in series, the second usually cleans up the release of the first. A ceiling at 0 dBFS can still clip after lossy encoding. Over-limiting removes detail in the quietest passage before it touches the loudest one.
