Measurement Anatomy

A Measurement in FuzzMeasure stores a measured impulse response, and some metadata that helps to identify and analyze it.

The title, notes, and date information attached to each measurement helps to provide further context about when the measurement was captured, and in what environment. A color is also attached to each measurement to help you easily identify them when displayed in graphs.

The impulse response data is stored as 32-bit floating point values sampled at the same rate the measurement was captured.

Measurements also capture information about how the measurement was performed. For instance, the log sweep settings, sample rate, and other such data about the measurement is captured at the time the record is created.

In addition to the above, each measurement stores an Analysis Window—a combination of a start time, duration, and window shape that is used to help calculate certain graphs. For instance, the Analysis Window allows you to gate a measurement to generate a quasi-anechoic frequency response graph. The Analysis Window's start and duration are also used to generate the Energy Decay Curve that is fed into the ISO3382 graphs.
