PSP MicroWarmer is a single-band tape emulator and limiter plugin from PSP Audioware. It adds analog-style warmth, density and saturation to individual tracks or groups, and is available as a VST3, VST2, AU and AAX plugin.
PSP MicroWarmer is a simplified version of PSP VintageWarmer, built for single tracks rather than full-mix or multi-band work. Its processing engine is based on the Single Band mode of VintageWarmer, which PSP says it matches in sound quality. The interface is kept deliberately simple, with shelf filters for bass and treble and calibrated VU and PPM metering. It also ships with a library of presets.
PSP MicroWarmer models the saturation behavior of analog tape recorders. The developer says care went into its overload characteristics, so the plugin adds density and a rounded, warm character when driven.
Processing runs in 64-bit double-precision floating point, and sample rates up to 192kHz are supported. Shelf filters for bass and treble use constant corner frequencies, which PSP says are optimized for track processing.
The plugin works on a single band, so it suits tracks, buses and groups where full frequency control is not needed. For that purpose, PSP Audioware describes it as a limiter and tape-style compressor for shaping dynamics and average level.
VU and PPM meters are calibrated and include overload indicators, which help you set drive levels. PSP says this version has the lowest latency of all the Warmer plugins for its algorithm.
