NOISE by Circles is a free sound-capture companion for musicians, producers, and sound designers. Turn sounds from the world around you into production-ready material for the NOISE desktop plugin or any DAW. Record a sound with your iPhone, shape precise loop regions directly on the waveform, and immediately explore the result as a playable eight-pad instrument. Choose a root key and scale, shift octaves, and switch between one-shot and looping playback while trying Hit, Hold, and Swell response shapes. When the sound is ready, export the complete recording or every loop region as clearly numbered 24-bit / 48 kHz WAV files. Optional boundary fades help avoid clicks, while the built-in 50 Hz high-pass option removes unwanted low-end rumble.

FIELD KIT is an audio playback instrument built for turning recorded sound into evolving texture, rhythm, and atmosphere. Load an audio file and create up to four independent playback windows across the recording. Each window can move through a different section of the source with its own playback speed, direction, crossfade, drive, filtering, level, and pan. Use FIELD KIT to pull overlapping textures from long field recordings, transform environmental sound into ambient beds, create asynchronous loops, or find entirely new material hidden inside a recording. Three modulation sources can be routed independently across the playback windows, allowing parameters to drift, pulse, and evolve over time. Features include: - Up to four independent playback windows - Forward, reverse, and ping-pong playback - Variable playback speed - Adjustable loop crossfade - Drive and filtering per window - Independent level and pan controls - Three routable modulation sources - SPLICE for working with multiple audio sources - Save and recall .fieldkit files to share across platforms - Internal recording in Standalone mode - Standalone app and AUv3 Audio Unit - Host transport support in compatible AUv3 hosts FIELD KIT was designed around a simple idea: a recording doesn't have to be played from beginning to end. It can be a place to explore.
