Perforator vs BLEASS Granulizer
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Perforator
This app is a rhythmic gating audio effect that creatively manipulates incoming audio to generate rhythmic patterns. It offers two gating mechanisms, including an AMP EG gate and a low-pass filter, to achieve various sound effects.
- Rhythmic gating audio effect
- AMP EG gate and low-pass filter
- Syncs with project tempo
- Independent left/right channel editing
- Built-in preset manager
- AU MIDI output

*** Note: Perforator is an AUv3 Audio Unit plugin; which requires an AUv3 compatible host app, such as Garageband, Cubasis, BM3 or AUM *** Perforator is a rhythmic gating audio effect: it will creatively snip, cut, gap and filter incoming audio to create rhythmic patterns out of sustained sounds. By tuning the slice envelopes you can create anything from classic staccato "trance gate" sounds to emulations of sloppy pumping sidechain compression. Two gating mechanisms can be dialled in: an AMP EG gate (the traditional way of gating) and a 12dB/Oct lowpass filter which will rapidly carve away high frequencies from your sound to effectively silence them. - AUv3 Audio Effect, works in all AU compatible hosts - automatically syncs with your project's tempo - edit Left an Right channel independently - built-in preset manager with a ton of factory presets - all AU Parameters exposed for host automation - user manual available on ruismaker.com - Universal: works on iPad, iPhone and iPod Touch - Bonus Feature: AU MIDI output* * AU MIDI: both envelopes (L+R) can send their values out as MIDI CC messages to mimic 'parameter lock' messages in other plugins/apps. Note: this feature requires iOS11+ and a host compatible with AU MIDI from effects.

BLEASS Granulizer is an innovative granular effect processor crafted for musicians, producers, and sound designers who want to transform incoming audio signals into rich, evolving textures and immersive soundscapes. It works by slicing audio inputs into small "grains" and reassembling them through real-time modulation of different parameters that you can visualize thanks to a 3D visualizer: Modulate - Volume - Pan (represented by width in the visualizer) - Size ( = grain’s duration) - Density ( = frequency of grains generation) - Offset ( = the amount of time between record and play represented by the depth in the 3D visualizer) - Backward/Forward Playback Direction - Shape ( = grain’s envelope, represented by the height dimension in the visualizer) - Warmth ( = strength of the distortion applied to the grain) - Tune ( = grains can be pitched up or down according to different modes: “Fine” / Chromatic / Major / Minor / 5th / Major 7th / Minor 7th / Octave. The amount of randomization can be set with the “dice” knobs. Density, grain size, and offset range can be freely synced or beat synced to the host’s tempo. Touching and holding the visualizer modifies pan and density. BLEASS Granulizer takes up to 4 sources from different busses as inputs (compatible host required such as AUM). When multiple busses are on, each grain is randomly extracted from one of the available sources. BLEASS Granulizer is your unique granular texture effect for reshaping any audio source into a dynamic granular soundscape in ways you've never imagined.
