Plug your headphones into your iPhone and wander in the streets to catch noises, voices, and horns. The app is continuously recording sounds around you and automatically generates loops. Those loops are processed in real time by granular effects that transform them on the fly. To get a sense of what the recording will sound like when immersed in a track, you can import and play your own premade beat. Once you’re happy with it, you can export the loop to incorporate it into a larger DAW-based project. Feature list - Designed exclusively for iPhone and iPad - Slick native UI - Continuous recording of the surrounding sounds - Loops generated from the recordings, automatically updated each four bars - Four different effect sets to sculpt the generated loops in real time - Effects based on granular synthesis - Importation of drum loops from iCloud, Dropbox, AudioCopy, AudioShare, Mail, Airdrop and more to get an sense of the generated loops in a full audio track context - Touchable amplitude envelope to easily shape the sound - Sound export in .wav format

QuadroSphere is a great tool for bringing an instrument to life by creating a soundscape with a constantly moving sound source. QuadroSphere splits the incoming audio signal into 4 distinct coloured frequency bands using the frequency bar. Each band has an associated coloured sphere allowing you to control the pan, stereo separation and volume level. You can use this plugin as a way to impose subtle control over stereo placement with little or no movement, or go crazy with random automation. Adding effects such as reverb or delay on a specific frequency band can help create a lush atmospheric swirling which surrounds the listener. This is great for musicians trying to create minimalistic ambient or tranquil soundscapes. You can create up to 12 snapshots of the sphere parameters and effect settings, then morph between them at a designated speed (measured in beats). You can also enable continuous randomization mode, and have full control over which spheres and control which parts are automated. You can also use QuadroSphere as a stereo splitter, using the additional outputs to add your own effects to band outputs. Key Features: ○ 4 Configurable frequency bands. ○ Control stereo separation, level and pan for each band. ○ Create up to 12 Snapshots. ○ Morph between various panning, width and frequency band levels. ○ Modulation control for automated sweeps around pan center. ○ Convert MONO signals into a pseudo-stereo image. ○ Per band Haas, Delay, Reverb, Chorus and Compressor. ○ Allows combined and individual per-band audio outputs. ○ Continuous randomized morphing of the stereo field. ○ Built in Preset Manager with drag and drop support. ○ Power and Solo for each band. ○ Controlable morph speeds. ○ Various animated transition modes. ○ Access most options using AU parameters or MIDI CC control.
