Loop Breaker vs Wave Slicer
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Loop Breaker
This app transforms your audio loops into evolving compositions by introducing random modifiers and effects. It encourages creative exploration by letting you decide how to alter your sound or letting the app make choices for you.
- Gamified audio processing
- Modifier system for effects
- Probability system for modifier appearance
- MIDI CC control for probability
- Preset system for saving/recalling stacks
- Record and resample audio output
- Standalone app and AUv3 plugin

Loop Breaker is a gamified audio processing environment that periodically forces you to make choices about how your audio loops should change and how your compositions should unfold. This is primarily achieved through a modifier system; every few bars, a new modifier appears in a queue. You must decide which of your loops should be affected by the modifier. If you make no choice, Loop Breaker will decide for you. Change is the only constant. Modifiers include standard audio effects like reverb, delay, chorus, filters, granular delay, auto-pan, and tremolo. Each of these effects has multiple parameters that are set on the fly and include various onset times. Other modifiers effect loop playback: you can change the playback speed, reverse playback direction, time-stretch, re-pitch, move loop brackets via the parts system, and slice loops and then shuffle, arpeggiate, or repeat them. Modifiers stack. Within minutes, your loops will wander down their own paths and recombine to create something previously unimaginable. Loop Breaker also contains a robust probability system for controlling how likely it is that modifier types will appear in the queue and how likely it is that an individual loop will be targeted for modification, should you cede decision-making responsibilities to Loop Breaker. The probability system responds to MIDI CC messages, so you can dynamically change probability settings with MIDI controllers, automation lanes in your DAW, or via modulation sources. Loop Breaker also contains a preset system for saving and recalling modifier stacks. Take your explorations as far as you want, save a new preset, and then recall it later on, even between sessions. Like the pads and probability system, presets also can be controlled via MIDI. Still not enough exploratory madness for you? Record and resample the audio output and then re-apply it to a pad or process it further in your DAW. Loop Breaker works both as a standalone app and as a AUv3 plug-in. Loop Breaker knows that you have a hard drive full of 4-bar loops that you never turned into finished compositions. Loop Breaker wants to help. Loop Breaker wants to make sure you don't get stuck in a loop.

Wave Slicer cuts a sound down to the piece you actually want. Load a track, record something, or send a file to it from anywhere on your phone — then zoom in until you can see the individual samples and cut exactly there. WHAT IT DOES A waveform that stays smooth on a ten-minute file and keeps going down to sample level. Drag the edges of a selection, slide the whole selection along, or draw a new one. Every edge snaps to a zero crossing, so a cut never clicks. A full effect chain that you hear while you turn it. Transpose by semitones, high-pass and low-pass with resonance, tanh saturation, bitcrush and sample rate reduction, echo with feedback, and a reverb that can ring out for eight seconds past the end of the slice. An amplitude envelope you draw by hand. Tap to add a point, drag to move it, bend the curve between two points. The same envelope drawing as the pitch curve in Drum Rack. Fades on both ends, and a loop crossfade that folds the tail over the head so a loop comes round without a seam. Export as a 16 or 24-bit WAV, with TPDF dither on 16-bit. The file lands where you choose to save it, named so you can find it again in a DAW browser. Record straight from the microphone when you want to sample something in the room. Echo cancellation and noise suppression stay off, because those are built for speech and ruin anything worth sampling. Twelve sounds are built in to start with, including two drum loops on the grid, so there is something to cut the moment you open it. WHAT IT DOES NOT DO No account. No sign-in. No advertising. No analytics. No tracking. Audio you load, record or export never leaves your device. The app asks the internet for exactly one thing: a small text file holding the current links shown on the last screen. FROM THE LAB Wave Slicer is part of Lumlux Art Lab, a set of free browser tools for people who make music. The same slicer runs on the website, so you can try it before installing anything. Made in Antwerp by FDR-Sound.
