Combine loudspeaker measurements into a single response, for use in any audio tool & for plotting.

Combining multiple loudspeaker measurements – especially for spatial averaging – is valuable when doing any loudspeaker tuning or equalization, including the creation of FIR filters. It can result in more accurate filter design and smoother overall system response.

Unlimited number of input measurements

Multiple export file formats

Multiple averaging modes




  • Intuitive workflow from measurement loading to average response export.
  • Unlimited number of input measurements (subject to computer memory limits).
  • Comprehensive range of measurement file formats.
  • Multiple averaging modes including
    • Complex
    • Power with flat or zero phase
    • Power with minimum phase
    • Power with minimum phase plus reference measurement excess phase
    • Power with complex average excess phase
  • Multiple level matching modes
  • Automatic time alignment plus manual relative delay adjustment.
  • Averaging weights and polarity inversion.
  • Continuous calculation as parameters are updated.
  • Multiple export formats including impulse responses, and linear or log frequency transfer functions.
  • Average response samples rates of 12, 24, 44.1, 48 96 and 192 kHz.
  • Input measurements can have different sample rates and their samples rates don’t have to match the averaging sample rate.
  • Moveable license: deactivate and reactivate on a new computer
  • macOS and Windows versions. (Windows 10 and above; 64 bit.)
  • Integrated help (requires internet access).



FIR Designer and FIR Designer M already have measurement averaging functionality built-in (license holders don’t need to separately purchase Averager to create averaged measurements for use in FIR Designer and FIR Designer M).

Averager is ideal for use with FIR Creator & FIR Creator EX, as these don’t include built-in averaging functionality.
