L3V3LL3R

L3V3LL3R (stylized with leetspeak numbers) is a popular, free audio compressor plugin available in the Native Instruments REAKTOR User Library. It was designed and developed by the well-known audio engineer and educator Dan Worrall. Key Characteristics & Sound Profile

Vintage Hardware Emulation: The software is a faithful digital model of the iconic “Leveller” hardware compressors from the 1960s.

Aggressive Character: While it can handle subtle parallel compression, the plugin is highly celebrated for how it reacts when pushed to its limits. It is a favorite among music producers for creating heavily “squashed” drum tracks.

Versatile Modes: The processor features distinct operational settings. Producers frequently use “Mode I” to bring out the harmonic character of individual instruments (like analog synthesizers) and “Mode II” for tailored vocal compression. Technical Requirements

To use L3V3LL3R, you must run it inside REAKTOR (either the full version or the free REAKTOR Player) by Native Instruments, which acts as the host environment within your Digital Audio Workstation (DAW). Because it is hosted in the community library, it is completely free to download.

Note: If you were instead looking for a multi-band mastering limiter, you might be thinking of the Waves L3 Multimaximizer series, which is an entirely separate commercial line of industry-standard mastering software.
