Echo Pitch Audio Effect With Audiobus
Author View comments Tags Tags: , , , , , ,

Echo Pitch pitch-shifting multi-delay for iPhone. Echo Pitch has 4 delays where each delayed signal can be pitched one octave up or down in 1/2 steps, and can function as a 4 voice harmonizer. Echo Pitch also has a built-in looper, amp simulator and reverb. Each of the four delays can be routed into the other for incredible, swirling, ambient washes and otherworldly sounds.

Thanks everyone for all the positive feedback and feature requests.
We’ll keep the updates coming!

Echo Pitch works best with an iOS audio interface, such as the Fender Slide or iRig. Echo Pitch is also Audiobus and Inter-App Audio compatible (for IAA, launch Echo Pitch first).

Virsyn BandShift Frequency Shifter App
Author View comments Tags Tags: , , , , , ,

BandShift is a multi-band auditory filter and frequency shifter taking a new approach to manipulate the pitch of complex sound sources in realtime. The well know analog Bode frequency shifter shifts all frequencies in an input up by the same amount and thereby alters their harmonic relation and tends to produce inharmonic results. But it’s perfect in dealing with transients and sounds smooth even with high amounts of down pitching.

BandShift splits the spectrum in 27 bands and applies a different amount of frequency shifting to each band emulating a harmonic pitch shifting. This gives you perfect pitch shifting for all kind of drum sounds over a vast shifting range of +/- five octaves without disturbing the transients or introducing metallic distortions. The extreme range of shifting gives you access to a vast field of unknown sonic territory.

The possibility to apply different shiftings on each band gives you exciting possibilities: Suppose you have a drum loop which is perfect, but the bass drum is a bit too high or too low to fit in your mix then you can easily get the bass drum shifted a bit down and the rest of the spectrum remains unchanged. But it’s applications are not limited to drum sounds, they’re only limited by your imagination.

Lofionic Duplicat Icon

Lofionic Duplicat is a warm and lush tape delay effect for iOS, supporting AudioUnit Extensions, Inter-App Audio and Audiobus.

In addition to the Swell and Sustain controls found on the hardware equivalents, Duplicat introduces a tape Speed control, for fine tuning the rate of delay in realtime, and a tape Effect control which emulates the deteriorating effect of using worn tape by gradually introducing degradation to the feedback.

Duplicat is perfect for adding lush, organic sounding delay to your mixes ranging from trashy lo-fi grungy tones, through psychadelic swirls, to subtle slap-back.
