DIRLoader is a impulse response loader plugin with dual parallel impulse response load, crossfade, bias, and tune control.

DIRLoader is an impulse response loader plugin with dual parallel impulse response loading capabilities. The plugin features parallel IR processing with independent impulse response loading. Each IR includes real-time spectrogram visualization, per-IR bypass control, and the ability to unload or replace impulse responses on the fly. Global mix bias allows precise control over the combined output, while an integrated waveform display shows the input signal in either dry or wet mode. The XFade control enables smooth crossfading between impulse responses, and Tune reshapes the active IR by morphing its frequency response into a target response, allowing for creative spectral blending and tonal transformation. Technical highlights include parallel multi-IR convolution processing, real-time IR spectrogram analysis, phase-coherent crossfading between impulse responses, frequency-response morphing for tonal reshaping, global mix bias control, and low-latency real-time–safe DSP across platforms.
