*** Note: DerVoco is an Audio Unit effect extension and requires an AUv3 compatible host app, like AUM, BM3, Cubasis or GarageBand. It does not run as a standalone app *** Make your synths or drums speak and sing! DerVoco is a vintage vocoder emulation. DerVoco uses analog modelled components including filters, envelope followers and companders to create a warm vintage sound instead of digital techniques like FFT. Features: • AUv3 Audio Effect and Audio Music Effect, works in all AUv3 compatible hosts. • Internal polyphonic VCO may be used as a carrier and can be controlled via MIDI, when plugin is loaded as AU MFx. • A special "input mode” where the carrier and modulator signals are encoded as the left and right channels of a stereo input signal. In this mode any synth plugin (e.g. BeepStreet Zeeon) may be used as a carrier signal. • 11 or 15 bands with on-screen equalizer. • Controllable filter resonance continuously blends from smooth to sharp and ringing sound signature. • Built in compressor and noise gate • Optimised to the limits: 60 filters take 4% CPU on latest iPads.

Verdict
The clearest difference is rating: Voice Synth at 4.1 against DerVoco's 3.7. Voice Synth also leads on review sentiment (62% vs 43%) and ratings volume (333 vs 23). DerVoco's advantage is price ($2.99 vs $8.99) and chart position (#154 vs unranked). On ads, in-app purchases, monetization model and device support there is nothing between them.
