Sirens' Chor vs VA

This one is quite experimental and CPU heavy app! While working on my Chord Detector app I came up with the idea to play the found harmonics with sine wave oscillators so I can hear what the algorithm is hearing :) It turns out to be an interesting output that led me to creation of this audio effect app. What happens here is that the input is analysed for main harmonics in the range of 80Hz to 1500Hz. Then a series of sine wave oscillators are set to play those harmonics with the exact frequency and volume and their output is added to create a second voice. This second voice can then be mixed with the input to create some kind of chorus or played alone. All this is CPU heavy process so it should be used with care... Also to make this effect possible I had to use limited range 80Hz to 1500Hz so it is not suitable for every instrument and you have to keep that range in mind when producing. Some very fast volume and frequency changes are applied to the oscillators. The app is AUV3

Play, sequence, record, and shape sounds from one direct interface inspired by classic hardware synths. No subscription. No in-app purchases. No ads. No account required. — SYNTHESIZER — • Up to 16-voice polyphony • Two oscillators plus a sub oscillator • Independent oscillator noise controls • Multi-mode filter with resonance • Amp and filter ADSR envelopes • One LFO per voice • Chorus, phaser, delay, and reverb effects Explore the included factory sounds, customize any preset, mark favorites, and save your own creations. — SEQUENCER & WAV EXPORT — Record and loop sequences while shaping the sound, change the pattern length, or use KEY mode to transpose a sequence from the keyboard. Capture VA-1’s stereo output while you play, then preview, save, or share the recording as a WAV file. Sequencer loops can also be exported directly to WAV using the current sound, tempo, and effects. Recording captures only VA-1’s internally generated output. It does not use the microphone or record audio-interface inputs. — MIDI & AUv3 — • External MIDI input and output • Send MIDI from the keyboard or sequencer to external instruments • MIDI Learn for mapping hardware controls • Standard MIDI CC support • AUv3 instrument support in compatible hosts • Background audio • Support for class-compliant USB audio interfaces — ONE PURCHASE, ALL YOUR DEVICES — VA-1 is a universal purchase. Buy it once and install it on iPhone, iPad, and Mac at no additional cost.
