Echo Pitch pitch-shifting multi-delay for iPad and 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 freeze loop, amp simulator and reverb. Each of the four delays can be routed into the other for incredible, swirling, ambient washes and otherworldly sounds. Echo Pitch works best with an iOS-compatible audio interface. Echo Pitch is also AUM/Audiobus compatible - as Inter-App Audio or Audio Unit. (Please note that the standalone/IAA version of Echo Pitch is now legacy. While the AU Echo Pitch has the same functionality, the pitch shifting is far superior. In addition, there are sonic differences between the Reverb, Master Delay EQ, Delay drives in the AU vs the Standalong/IAA version. But you get both updated AU and legacy IAA. Use whichever you prefer!) Brought to you by Avi Bortnick and Maximos Kaliakatsos-Papakostas.

Verdict
The clearest difference is review sentiment: PD1 at 100% against Echo Pitch's 68%. PD1 also leads on update cadence (every 6 days vs every 2 weeks) and price ($3.99 vs $4.99). Echo Pitch's advantage is iOS requirement (15.6 vs 17.5). On ads, in-app purchases, monetization model and device support there is nothing between them.
