Speak Unit is a speech synthesiser audio extension for use in Garageband and other compatible music software. You enter up to twelve phrases that are each triggered by a unique note. Ideal if you need robotic vocal for your musical compositions, or any other creative uses. To use - Add the Speak Unit audio extension instrument to a track in your music software - Select a note using the up and down buttons on the Speak Unit's chest. - Enter a phrase - Choose a voice - Press the save button to store the phrase in the Speak Unit ready for synthesising. - Press the speak button if you wish to audition the phrase. - Play or sequence that note to play the phrase in your composition. The stand alone app can be used to speak the phrases triggered by a row of note buttons.
lfoch
This app generates complex LFO waveforms with multiple outputs for creating "chase" effects. It offers two LFO generators with phase modulation, adjustable suboscillators, and waveform morphing. It can output MIDI control change values and sync to tempo.
- Dual LFO generators with phase/ring modulation
- Suboscillator modulation with waveform morphing
- Adjustable waveform rate, type, and range
- Output 1-16 MIDI control change values
- Tempo synchronization and AUv3 MIDI Effect support
- Two modes: 'perform' and 'edit'
- Randomize parameter values

lfoch is an experimental LFO generator that can create "chase"-like effect with multiple outputs from a single complex waveform It features: - 2 LFO generators with phase modulation / ring modulation: - Each LFO generators contains 2 suboscillators; one suboscillator modulates phase of another - For each suboscillator you can set waveform rate, waveform type (with smooth morph between sine, triangle, sawtooth and square waveforms), nonlinear curve (for overdrive-like effect) and minimum/maximum range - The result waveform is a multiplication of two generated LFO waveforms - You can use 1..16 points from this waveform to output as MIDI control change values - You can toggle the "playback" (phase change) of each generator with I/II buttons - You can randomise parameter values with "dice" buttons - App has two modes for live usage - 'perform' mode has larger waveform view and some selected sliders (if any) - 'edit' mode contains all controls on one screen - Each generator can be synchronized to tempo. In this mode the "speed" value runs from 4 quarter forward to 4 quarter backwards speed, the fastest value in this mode is 1/32 - When running inside AUv3 host the app uses host's transport. - "free mode" setting allows you not to follow the host transport lfoch is a standalone app and an AUv3 MIDI Effect. AUv3 effect supports parameter automation and preset saving inside host. Standalone version currently does not output MIDI in background mode.Note for AUM users:This application starts with 16 control change outputs from CC 0 to 15 on MIDI channel 1. AUM has default mapping of the CC #7 (volume) for each channel. Please keep this in mind when setting it up together.

Verdict
The clearest difference is rating: Speak Unit at 4.8 against lfoch's 4.4. Speak Unit also leads on review sentiment (67% vs 50%) and price ($0.99 vs $3.99). lfoch's advantage is update cadence (every 20 months vs every 52 months). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
