iVoxel is not only an amazingly sounding vocoder - the unique concept of iVoxel turns this vocoder into a singing machine. iVoxel is a combination of a voice optimized synthesizer and a vocoder. The vocoder part is based on the Matrix vocoder from VirSyn used by many famous artists - one of them the well known german group Kraftwerk. The channel filters used by iVoxel are based on the Sennheiser Vocoder VSM201 resulting in a rich and fat analogue sound characteristic. The pitch follower and automatic tuning let you sing correct to a selectable scale. You can use iVoxel in many different ways: As a realtime vocoder talking into the microphone while playing tunes on the keyboard. The sound character of your voice can be changed in many different aspects like pitch, gender or breath noise. Use it to sing over your favorite iTunes song ! Record the analyzed spectrum of phrases and words from your own voice. Then use this voxel to play with your own voice on the keyboard or with the build in sequencer. Nearly 300 hundred prerecorded voxels are already included. iVoxel is Audiobus compatible and can be used in the Input, Filter and Output slots in the Audiobus signal chain. The carrier signal and the vocal signal can now be fed by any Audiobus compatible Apps. The output of your creations can be recorded to an audio file which you can use with other Apps and programs for further processing.

*** 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: DerVoco at 3.7 against iVoxel's 3.3. DerVoco also leads on price ($2.99 vs $6.99) and chart position (#154 vs unranked). iVoxel's advantage is review sentiment (55% vs 43%). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
iVoxel costs $6.99 and DerVoco $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.
DerVoco holds the better App Store score, 3.7 against 3.3. Both are backed by a comparable volume of ratings — 17 and 23 respectively. Written reviews complicate that: 55% of iVoxel's written reviews are positive against 43% of DerVoco's, so the app with the better star average is not the one people write more warmly about.
