SpinBud vs Bit Splitter

SpinBud is a rotary spatial modulation effect for iPhone and iPad. It is built around a simple scene: your sound drives up to 3 rotating speaker plates, each plate can hold up to 3 horns, and a fixed stereo mic rig captures the movement. Use SpinBud on organs, synths, guitars, pads, drums, vocals, or full mixes when you want moving stereo color, gentle cabinet bloom, tempo-synced tremolo, wide chorus-like motion, or unstable broken-speaker textures. ROTARY PLATES - Use up to 3 independent rotating plates - Set each plate's speed, direction, horn count, level, phase, and band range - Choose free-running speed in Hz or sync plate motion to host tempo - Shape speed changes with Ramp Up and Ramp Down - Drag plates directly in the visualizer for manual spin gestures SPLIT-BAND MOTION - Send different frequency ranges to different plates - Start quickly with band presets such as Low, Body, Mid, Presence, Air, Full, and more - Adjust custom Min Freq and Max Freq values per plate - Use the spectrum view while finding useful band ranges - Keep low movement slow and high movement fast, or overlap bands for denser modulation STEREO MIC RIG - Capture the rotating plates through one shared stereo mic setup - Adjust mic angle and stereo spread - Set left and right mic distance independently - Blend dry and wet on the main output - Add Room for a small cabinet-style space around the wet signal ROTARY CHARACTER - Add Doppler for pitch movement from approaching and receding horns - Use Directivity to control how focused the horn movement feels - Increase Tone to darken horns as they turn away from the microphones - Add Wobble for motor drift, loose movement, or broken rotation - Push the excitation path with Drive PRESETS AND ROUTING - Load factory presets for chorale, tremolo, brake, wide, chorus, wobble, shimmer, lo-fi, and multi-plate setups - Save your own user presets - Run as a standalone app - Connect MIDI in standalone mode and use MIDI notes to flick individual plates - Use AUv3 multi-out in compatible hosts to route separate wet stereo stems for Plate 1, Plate 2, and Plate 3 SpinBud is not a full Leslie simulator. It is a rotating emitter plus fixed stereo listener effect for motion, width, rhythmic modulation, and split-band rotary sound design. The AUv3 FX plugin needs a compatible AUv3 host such as AUM, Logic Pro for iPad, Loopy Pro, Cubasis, GarageBand, BeatMaker 3, or another compatible host.

BIT SPLITTER A bit-plane manipulator. The input is scaled and quantized to an 8-bit value, then a single bit-plane of that value is used to reshape the signal. Where a bit crusher reduces resolution and hands back a degraded copy of the sound, the bit splitter operates on one specific bit and can either output that bit on its own, use it to gate the input, or mask the signal down to a chosen number of bits. MODES ISOLATE Outputs the chosen bit-plane on its own as a bipolar square wave. The most-significant bit behaves like a sign comparator, producing a hard square that tracks the waveform; lower bits flip more often as the amplitude moves, giving increasingly noisy, aliased fuzz. This is the most literal reading of splitting a bit out. GATE Passes the dry input only while the chosen bit is high, and mutes it otherwise. The signal is chopped by its own bit-plane, producing glitchy, rhythmic gating that still carries the source material underneath. MASK Zeros every bit below the chosen one and reconstructs the result to audio. This is a bit-depth reduction in which BIT sets how many low bits are discarded: at 0 the signal is untouched, at 7 only the most-significant bit survives (1-bit). Closest of the three to a classic crusher, but with arbitrary bit selection. CONTROLS BIT In Isolate and Gate, selects which bit-plane is used, from 0 (LSB) to 7 (MSB). In Mask, sets the lowest bit that is kept, so it acts as a resolution control. Lower bits track fine detail and toggle rapidly; higher bits track the gross shape of the waveform. Range: 0 to 7 THRESH Input drive into the quantizer. The signal is divided by this value before being mapped to a byte, so lower settings push the signal harder into the 8-bit range (clipping into it sooner) while higher settings keep it quieter and more centered. It changes which bits are active for a given input level, and so reshapes the character of every mode. Range: 0.01 to 2.0 MODE Selects the bit-plane operation: Isolate, Gate, or Mask (see above). Switching mode changes what BIT means, so the two are best adjusted together. MIX Controls the balance between the unprocessed (dry) input and the processed (wet) output. At 0% only the dry signal is heard; at 100% only the processed signal passes through. Intermediate values produce a linear crossfade, useful for blending the harsher modes back under the source for parallel-style processing. Range: 0% to 100%
