jAmp Convolve is a professional audio convolution plugin (AUv3) for iOS and macOS, using advanced neural network‑powered impulse response generation to deliver realistic guitar cabinet, bass cabinet, and reverb simulations — ideal for musicians, producers, and sound designers.

Descent is a real-time granular effect that captures incoming audio, breaks it into tiny grains, and scatters them across time and pitch. The result: everything from subtle thickening and rhythmic delays to vast frozen soundscapes and shimmering pitch-shifted clouds. GRANULAR ENGINE Control up to 50 simultaneous grains with independent settings for duration, overlap, and envelope shape. Play grains forward, reverse, or randomly mixed for tape-style effects, reverse swells, and glitchy textures. PITCH SHIFTING WITH QUANTIZATION Transpose from -24 to +24 semitones. Lock pitch shifts to specific intervals—octaves, fifths, or any chromatic combination—for harmonically correct shimmer and transposition effects. SIX-AXIS RANDOMIZATION Independently randomize pitch, pan, position, amplitude, duration, and grain count. Dial in subtle organic movement or push into complete textural chaos. DIFFUSION AND FEEDBACK High-feedback mode with a diffusion control transforms delays into lush, reverb-like washes that never get harsh or run away from you. TEMPO SYNC Lock grain timing to your session's tempo or let textures evolve freely in untethered mode. 35 FACTORY PRESETS Covering shimmers, delays, reverbs, pitch effects, and experimental sound design. Cross-platform XML presets are compatible across all Audio Damage plugin formats and operating systems. SOUND DESIGN IDEAS Add subtle depth with a few long grains and minimal randomization Create rhythmic delays with short, quantized grains at high feedback Build infinite sustain pads by freezing audio with high grain count and overlap Craft shimmer effects by quantizing pitch to octaves and fifths Transform vocals into ethereal textures with diffusion and wide panning AUv3 compatible. Runs standalone or hosted in AUM, ApeMatrix, Audiobus, Cubasis, GarageBand, and other AUv3 hosts on iOS 13 or newer. From Audio Damage—making creative software for discerning musicians since 2002.
