Advanced field recorder combined with a sound warp engine and a collection of ready to use dynamic presets for iPad and iPhone. Discover new ways to create and construct unusual and exciting sounds from any environmental audio recordings or samples recorded from other apps through Inter-App audio or Audiobus. The main advantage is that you can record and modify samples along the way within the single app. You can record sounds and noises, delete unwanted parts and then use presets to give a whole new sounding or create spectacular soundscapes and textures to use them as loops in this app. And even use FieldScaper as effect in real time with other apps or external input. The FieldScaper consists of two main parts. The first part is the field recorder with special options for different ways of record environmental sound from microphone or record other sound sources. With the sample editor you can cut or split the source sample for more convenient use. The second part is the scaper sound engine that with using dynamic presets can easily transform the most ordinary sounds into something absolutely different. These parts connect with each other into one whole but you can use recorder or scaper independently. The FieldScaper supports complete MIDI control for all faders, knobs and many buttons. You can change the parameters of oscillators, filters, delays and mixer by using any external MIDI controller or MIDI apps like sequencers. With the MIDI controllers this app becomes very comfortable to use at live performance. Field recorder: - Auto start record when input signal appears. - Auto stop record when signal below threshold or by time. - Record series of samples by a signal presence. - Recorder timer in seconds or measure (sync with BPM). - Input signal monitor with different modes. - Automatic gain control, cut off input filters and noise gate. - Advanced sample editor (delete, trim, split, cut, copy, paste, undo). - Filter and normalizer for recorded sample. Scaper sound engine: - Loop based mode for processing input in real time as effect. - Three sample-based oscillators, each with set of effects. - Low-pass, high-pass, band-pass, band-stop filters with resonance. - Two range delay with smooth time change and additional modes. - Advanced spatial mixer / reverb with changing of side and distance. - Three-band parametric equalizer for each oscillator. - Wide range changing of oscillator speed with option of reverse. - Distortion effect based on breaking addressing of samples (like on circuit bending). - Complex effect contains lofi, overload, noise, ringmod, flanger, phaser. - Step sequencer can control selected parameter and envelope generator (ADSR). - Individual or group of LFO for each effect with additional modes and BPM sync. - The "Main effect" function for control several parameters simultaneously. Additional features: - More 50 predefined presets with wide range of effects. - Scenes for storing and loading all operation parameters. - Pack the scene and all its samples and presets to single file. - Convenient file manager with groups of files by name or date. - Access samples and records via standard iOS app "Files". - Complete MIDI control for all faders, knobs and other modes. - Adaptive UI for portrait and landscape orientation. - Different color schemes available for UI. - Detailed application description (built-in and PDF file). - Inter-App audio compatible (with transport and BPM controls). - Supports Audiobus 3 with "State Saving" and MIDI features. - Supports Ableton Link with start / stop sync. Requirements: Third generation of iPad or fifth generation of iPhone and higher is required.

Circa runs as a standalone app, or as an AUv3 plugin in hosts such as GarageBand, Logic, AUM and Cubase. Equal parts workhorse and abstract creative tool, Circa is a six track multi-layer looping environment that can do most of the things your popular floor pedal looper can while also paying homage to the serendipitous world of ambient looping. Each layer can sync to the host, a master loop, or free run, and can be triggered in sync, with an audio signal, or freely. Circa has seven stereo outputs (including a dedicated cue output for monitoring) and built-in reverb and delay. Add in a complete MIDI control and LFO modulation system and Circa is a full looping workstation. Features -- Multi-Layered Looping Circa has six layers that can operate independently or in sync with each other and/or the host. Circa can record from the stereo input, or self-record via an internal buss for interesting feedback possibilities. -- Standalone Or Plugin As a standalone app, Circa has its own audio and MIDI settings: choose your audio interface, sample rate and buffer size, pick the input pair, send each of Circa's seven outputs to any output pair on your interface, and select a MIDI input. Sync to incoming MIDI clock, or let Circa set the tempo from your first loop. As an AUv3 plugin, it lives inside your host and syncs to its transport. -- Designed To Be Touched And Played Circa's user interface is made for tactile manipulation, with touch strips for speed and position (including dedicated pages). The position strip can be further subdivided with slices. All this works together to turn a looping effect into a playable instrument. -- Easy To Get Along With Circa's layers each have an undo for destructive edits like recording, overdubbing, and erasing. -- Controllability And Modulation Circa has 30 modulation slots. Each one can map a MIDI controller to any of Circa's looping functions, or run an LFO: seven shapes, free-running or tempo-synced, with rate, phase and level, modulating speed, start and end position, level, panning, delay and reverb sends, filter frequency and resonance, or the slice the play head is on. LFOs swing around wherever each control is set, so the knobs stay in charge. -- Self-Contained Circa has a full internal mixer, filtering on each layer, and studio-quality send reverb, send delay, parametric EQ and compressor taken directly from Audio Damage's extensive effect library. -- Expandable And Performance-Ready Circa has 7 outputs in all: six assignable stereo outputs and a cue output for monitoring. Send any layer to any of the six stereo outputs, while keeping the cue for soloing, recording, and editing, unheard by the audience. In the standalone app, each output can go to its own pair of outputs on your audio interface. -- Ecosystem-Aware Circa's user presets are cross-platform compatible, and work on any instance of Circa, whether on macOS, Windows, Linux, or iOS. In addition, sessions created in GarageBand or Logic on iOS will open in the desktop version on macOS if you have purchased a license to that version.

Circa Looper's advantage is update cadence (every 3 weeks vs every 2 months) and price ($7.99 vs $9.99). On ads, in-app purchases and monetization model there is nothing between them.
