A single loudspeaker measurement indicates how a loudspeaker sounds at a single point in space. This is often not representative of the response of the loudspeaker across a variety of radiation angles or locations in a room. Combining multiple loudspeaker measurements into a single response can be useful in understanding the average behaviour of the loudspeaker and can be useful when designing crossovers, in multi-way loudspeakers, to work relatively well across a range of dispersion angles.

Averager is a tool for combining or averaging multiple loudspeaker measurements into a single measurement. Features include:

  • different gain modes for matching measurement levels,
  • bulk delay adjustment,
  • automatic and manual time alignment,
  • different averaging mathematical techniques (including complex and power),
  • transfer function and impulse response views, and
  • a variety of export file formats.

The following pages provide more details on the workflow.

Project or Session files

Use the menus to load and save Averager project or session files. The files have the extension *.FDA – the same as the averaging session files used in FIR Designer.

  • FIR Designer 1 and FIR Designer 2 load and save a text file, considered version 1. Averager can also load this file.
  • Averager saves a binary file, considered version 2. The files will not open in FIR Designer 1 and the FIR Designer 2.6.0 or lower.

FIR Designer 2 will shortly be updated to use the version 2 file format.
