The extreme delay machine that you've never heard before. In short: This is a Karaoke echo machine. Words spoken in the iPhone's microphone will come back a few seconds later. It's like the echo effect you can hear at a mountain. You can get various kinds of effects by changing the delay time and the feedback rate. To make music: Tap on the table - it sounds like "tock"......"tock"....."tock"..... Clap your hands - you'll hear "tock", "clap", "tock", "clap", "tock", "clap"... You can produce simple musical patterns this way. Daily life use: Leave it as it is. It's fun to hear repeating sounds of ordinary life. You can use the stereo headset with the mic. Take a walk with the iPhone in your pocket and enjoy the repeating sounds around you. In detail: "Echochops" produces a feedback delay effect (an echo effect) on the sounds from the iPhone's microphone. The feedback delay is widely used to produce rich vocal and guitar sounds. It is also used as a special kind of musical performance. You can use "Echochops" not only as a "musical" application but also as a "noisy" experiment. Features: - Input and output level meter - Input and output level setting - Delay time setting, within 60 seconds. - Feedback rate setting, from 0% to 100% - Direct and Delay balance setting - Four types of audio filters (Lowpass, Highpass, Bandpass, Notch) - Audio filter frequency setting - Audio filer Q setting - Parameter control by audio input/output levels - Parameter control by tilting - Parameter control by rotating (a compass-equipped device only) - Mode setting to change delay time, "Glitch" or "Funny". - Output route setting, headphone/receiver or speaker. - Tilt angle setting for controlling - Upside-down portrait mode for efficient use of microphone and speaker - Delayed sound can be erased - Works with iPod audio simultaneously - Background audio playback (iOS 4.0 and later) [[ ATTENTIONS ]] Due to a latency of an audio input and output, the actual delaying time will be slightly longer than the setting. A natural feedback through the air may happen because the microphone and speaker are placed closely on the iPhone. Distorted sounds or harsh grating noises will be produced depending of the setting of parameters. It would be better NOT to use this application if you cannot stand noisy sounds.

BLEASS Peaks turns filtering into a fully playable musical experience. Built around a powerful multi-peak bell-style filter engine, it lets you shape and animate sound in ways that go far beyond traditional effects. Create rich filter responses with up to 32 resonant peaks or notches, and sculpt their distribution, width, and behavior with intuitive controls. Everything is designed to be both immediate and deep, so you can quickly dial in a sound and push it into more experimental territory. Switch to MIDI mode and Peaks reveals its true potential. The filter becomes an instrument you can play, with frequency controlled directly from incoming notes. With up to eight simultaneous filter voices, you can turn rhythms into harmonies, add movement to static sounds, or create evolving textures that follow your performance. A comprehensive modulation system brings constant motion and life to your sound. 3 LFOs, envelopes, macros, and MIDI sources can be freely assigned to parameters, making it easy to build subtle movement or complex, reactive behaviors. BLEASS Peaks also includes a flexible effects section with five processing slots, allowing you to shape and enhance your sound further with distortion, dynamics, delay, and filtering. Every stage can be modulated, opening the door to deeply expressive and evolving effects. Despite its depth, Peaks remains fast, fluid, and intuitive to use. Its responsive interface, real-time visualization, and performance-ready controls make it equally at home in the studio or on stage. From precise tonal shaping to bold, animated transformations, BLEASS Peaks gives you a new way to hear and perform your sound. Optimized for iOS, it delivers high performance, low CPU usage, and a smooth, touch-friendly workflow built for modern music production. BLEASS Peaks Plugin is also available for Desktop.
