Turn any sound into lush pads, frozen textures, or drifting spectral motion with this multi-curve spectral blur and freeze effect. Frequency-Dependent Blur MagicBlur is a multi-curve spectral blur and freeze processor designed for transforming audio into pads, overtone glissandi, reversed textures, and glitch-like movements. Apply separate blur times per frequency or frequency range, then mix, modulate, and spread them to explore anything from subtle, washed-out ambience to extreme spectral experimentation. How Spectral Blur Works Incoming audio is analyzed into fast-moving spectral frames, each representing the frequency content of a small slice of sound. Instead of playing every frame in sequence, MagicBlur lets you pick frames at defined intervals and morph smoothly toward the next one. The Blur Time sets how gradually frequencies transition — and because MagicBlur supports independent blur times per frequency, you can shape different parts of the spectrum with fine-grained control. Freeze, Reverse & Transform Disable morphing to create a spectral freeze, holding each frame until the next is selected. Reverse the morph direction, apply envelopes, or shift pitch to create evolving drones and unique spectral transitions. Combined with MagicBlur’s modulation system, these tools unlock a wide range of expressive and experimental sound design possibilities. MagicBlur is an AUv3 audio effect plugin compatible with Logic Pro, AUM, Cubasis, GarageBand and many more. A Desktop version is also available for Windows and macOS (VST3 / AU / AAX).

About

Shruti Bot

Features
Read full description

Shruti Bot is a shruti box you can actually tune. Ten reeds, laid out the way a real box is — the low Pa and Sa drone pair, the full middle saptak from Sa to Ni, and the upper Sa. Every reed sits at its just-intonation ratio against the tonic, not the tempered approximation, so the drone locks together the way the instrument is supposed to. Pull up the bellows and it breathes. At zero no air moves at all and the box is silent; push it up and the drone gets louder and pumps harder, until the breathing turns into an audible tremolo riding on top of the tone. Pressure opens the timbre as well as the volume, so a stroke sounds like air moving rather than a fader going up. THE REEDS • Ten stops — Pa and Sa below, Sa Re Ga Ma Pa Dha Ni across the middle, Sa above • Just intonation throughout — 3/2, 9/8, 5/4, 4/3, 5/3, 15/8 against the tonic • A tapered tuning peg on every reed, plus or minus 100 cents, turned by hand • Detune two neighbouring reeds and they beat against each other — real acoustic summing, not an effect • A mixer fader per reed, independent of the stops, for balancing what's already sounding THE KEY • Any tonic across all twelve pitch classes, octaves 1 through 6 • A peg for each key, arranged as a keyboard • Every pitch class keeps its own microtonal trim, so you can build a tuning that isn't twelve-tone equal temperament and it stays put • The current note and its offset are always on screen MOVEMENT • Two free-running LFOs on every reed — one for tuning, one for level • They run at their own rates and drift in and out of phase, so the beating keeps reorganising and the drone never quite repeats • Set them slow and the box simply sounds alive THE CHAMBER • A swept resonance that moves like a body cavity rather than a filter sweep • Stereo chorus, the point where the drone opens out of the centre • Tape delay with a real moving head — sliding the time bends the pitch the way tape does, and the repeats darken as they recirculate • Plate-style reverb from a quarter second to six TWO INSTRUMENTS Tap the logo. Shruti Bot 2 replaces the reeds with four analogue oscillators — sine, triangle, saw and pulse — with phase shaping on each, from slow comb sweeps to full PWM. Everything else carries straight over: the same tuning, the same reeds switched on, the same effects. Only the sound source changes. No accounts. No subscriptions. No ads. No network. Nothing leaves your device.

Verdict

The call

The clearest difference is price: Shruti Bot at $1.99 against GSDSP MagicBlur's $29.99. Shruti Bot also leads on update cadence (every 8 days vs every 5 weeks). GSDSP MagicBlur's advantage is device support (3 vs 1) and iOS requirement (12.0 vs 17.0). On ads and in-app purchases there is nothing between them.
