TfxEcho is an echo effect AudioUnit Extension plugin. It uses delay lines which are inspired by BBD (bucket brigade device). BBD is used in various analog delay unit and is known for its warm and dark sound. 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 analog delay unit. The delay line is inspired by BBD, but it is not emulation of the any particular BBD. Unlike the typical BBD based delay unit, frequency range of the delay line is not limited. The delay line is capable to capture signal in higher frequency up to about 22KHz. Features AudioUnit Extension - Delay Time: From 20 ms to 1200 ms - Feedback: From 0 % to 100 % - Adjustable lowpass filter and high-pass filter. - Modulation rate: From 0.01 Hz to 10 Hz - Modulation width: From 0 ms to +/- 10 ms - Delay time can be synced to tempo provided by the host application. 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 review sentiment: TfxEcho at 80% against Ocean Sound's 0%. TfxEcho also leads on update cadence (every 3 months vs every 64 months) and chart position (#185 vs unranked). Ocean Sound's advantage is price (Free vs $4.99) and rating (5.0 vs 4.7). On ads, in-app purchases and device support there is nothing between them.

Ocean Sound is free to download; TfxEcho costs $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Ocean Sound holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: TfxEcho has 12 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 80% of TfxEcho's written reviews are positive against 0% of Ocean Sound's, so the app with the better star average is not the one people write more warmly about.
TfxEcho ships an update every 3 months, Ocean Sound every 64 months. The most recent releases landed on September 20, 2026 and September 16, 2026 respectively.
