Swept Sine Settings

Adjusting the swept sine settings is not usually required, but adjusting them can help overcome some issues that may crop up during the measurement process.

In the Measurement Popover you'll have access to modifying the swept sine duration and output level. By default, FuzzMeasure produces a full-range swept sine signal. We plan to offer more customizations in the near future.

Duration

A longer swept sine signal will produce measurements with a better SNR (Signal-Noise Ratio), but they will also produce much larger FuzzMeasure documents. Increase the measurement duration from the default of 1 second only when necessary.

Amplitude

This value will attenuate the output signal before it goes out the wire, and we only recommend you use this setting if your audio hardware does not deal well with 0dBFS output signals.

NOTE: Be aware that attenuating the swept sine signal also attenuates the signal used in deconvolution. That means that lowering this value will not lower the overall level of your impulse response measurements. It is up to you to ensure that an attenuated sweep signal is played and captured at a sufficiently loud level for accurate measurements.
