Professional Doppler Shift Simulator

Acceleration Profile Mode

Choose Acceleration Control:

Perfect Physics: Ideal motion with constant speed and perfect path
Custom: Manually adjust acceleration parameters with realistic variations
Manual: Complete control with time vs speed input (overrides path speed)

Audio Duration

Output Duration (seconds):

Duration determines how long the vehicle takes to travel the path (or total time for manual profiles)

Doppler Processing Method

Audio Method:

Variable Resampling: Creates true frequency sweeps visible in spectrogram
Spectral Shifting: Direct frequency manipulation for precise Doppler curves
Phase Modulation: Smooth instantaneous frequency changes for clean sweeps
