IR1A Convolver

Mellowmuse IR1A Convolver brings the character of impulse responses into your mix, from guitar cabinet coloration to spacious natural reverb and experimental effects. Its CPU-efficient, zero-latency convolution engine processes audio in real time, making it a practical choice for hobby producers shaping guitars, adding depth to instruments, or exploring unusual textures. Load standard mono or stereo WAV and AIFF impulse responses through the integrated file browser, or start with the included preset library. Adjustable IR length, high-pass and low-pass filters, and up to 250 ms of predelay help you tailor the response to your track. IR1A supports impulse responses up to 10 seconds at 44.1 kHz and uses 64-bit internal processing. A phase switch and customizable image previews round out a focused tool for producers who want flexible convolution without unnecessary complexity.
