TfxEcho is an AudioUnit Extension plugin that provides a BBD-inspired delay effect with a modern, high-fidelity signal path. It allows users to manipulate delay time and feedback to achieve classic analog-style pitch modulation without the traditional frequency limitations of hardware units. ## Key Features - **BBD-Inspired Delay**: Utilizes a fixed-length buffer and artificial clock to simulate the warm, variable-rate delay characteristics of bucket brigade devices. - **Flexible Modulation**: Offers modulation rates from 0.01 Hz to 10 Hz and widths up to +/- 10 ms for dynamic pitch-shifting effects. - **Integrated Filtering**: Includes adjustable high-pass and low-pass filters to shape the frequency response of the delayed signal. - **Tempo Sync**: Supports synchronization of delay times to the host project tempo for rhythmic precision. ## Who is it for? Music producers and sound designers seeking a versatile, high-quality delay effect for digital audio workstations. ## Links - [App Store](https://apps.apple.com/us/app/tfxecho/id1523777426?uo=4) - [Full Intelligence Report](https://marlvel.ai/apps/tfxecho) --- *This is an overview report.
