Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
TfxMod
This app provides a chorus and flanger audio effect plugin for mobile devices. It emulates the sound of vintage bucket brigade devices with adjustable parameters for delay, feedback, and modulation. It can be used with host applications to process audio input.
- Chorus and flanger effects
- BBD-inspired delay lines
- Adjustable delay time, feedback, and modulation
- Variable LFO rate and waveform
- Low-pass and high-pass filters
- Stereo width control

TfxMod is a chorus / flanger effect AudioUnit Extension plugin. It uses delay lines which are inspired by BBD (bucket brigade device). The delay line is identical to the delay line of the TfxEcho except its buffer length. The delay line uses fixed length buffer and an artificial clock to sample input signal in variable sampling rate. When the delay time is changed, the delay line can produce pitch change effect which is similar to the behavior of the BBD based chorus / flanger unit. Features AudioUnit Extension Chorus Effect - Delay Time: From 1 ms to 40 ms - Feedback: 0% - Modulation width: From 0 ms to +/- 1 ms Flanger Effect - Modulation Mode: mode1, mode2, and mode3 - Delay Time: From 1 ms to 20 ms (mode1&2), From 1 ms to 13 ms (mode3) - Feedback: From 0 % to 100 % - Modulation width: From 0 ms to 39 ms (mode1), From 0 ms to 19 ms (mode2), From 0 ms to 12 ms (mode3) Common - Adjustable lowpass filter and high-pass filter. - Modulation rate: From 0.01 Hz to 10 Hz - LFO Frequency can be synced to the tempo provided by the host application. - LFO Waveform: Continuously variable from sine wave to triangle wave. - Stereo Width: LFO Phase offset from 0 degree to 180 degree. Host Application - Host application uses system audio input as an audio source and processed audio signal is routed to the system audio output.

Verdict
The clearest difference is update cadence: Teraverse at every 4 weeks against TfxMod's every 3 months. Teraverse also leads on ratings volume (112 vs 6) and price ($2.99 vs $4.99). TfxMod's advantage is review sentiment (100% vs 83%). On rating, ads, in-app purchases and device support there is nothing between them.
