Virtual Dj Echo Doppler Jun 2026

Route the Echo Doppler to a send bus rather than the master. Play a snare drum or a clap on a drum machine or sampler. Tap the Echo Doppler button with a very short delay (1/32) and low feedback. The clap will sound like a laser rifle firing in a science fiction movie.

A digital echo is typically implemented as: [ y[n] = x[n] + \alpha \cdot x[n - D] ] where (D) is delay in samples and (\alpha) is the feedback coefficient (<1). The Echo Doppler effect modifies this by making (D) variable over time and applying a pitch shift to the delayed signal that correlates with the rate of change of (D). Virtual Dj Echo Doppler
