Pulse Mode & Window Shapes

Generate continuous pulse trains for transient response testing and timing applications

1 kHz tone, 10 pulses/second, 10% duty cycle

What is Pulse Mode?

Pulse mode generates a continuous train of short tone pulses at a specified rate. Unlike burst mode which plays a set number of bursts, pulse mode runs continuously.

Pulse mode is ideal for testing speaker transient response and creating metronome-like timing references.

Continuous pulses at the specified rate and duty cycle

Pulse Controls

The pulse panel provides control over the pulse train:

Tone Frequency: The frequency of the tone within each pulse (20-20000 Hz)
Pulse Rate: How many pulses per second (1-100 Hz)
Pulse Width: The duty cycle as a percentage (1-50%)
Window Shape: How each pulse is shaped (rect, hann, sine, blackman)

Duty Cycle: Pulse width determines what fraction of each period contains sound. 10% at 10 Hz = 10ms pulse every 100ms.

Window Shapes

Window shapes control how smoothly each pulse starts and ends:

Different window shapes for different testing needs

Shape	Character	Best For
Rectangle	Sharp, may click	Maximum transient impact
Hann	Smooth, click-free	General testing
Sine	Gentle transitions	Comfortable listening
Blackman	Ultra-smooth	Precision measurement
