The measurement application will play a frequency swept sine-wave through your loudspeakers and record the result with a measurement microphone. This requires a USB DAC or similar audio interface to be connected to your PC along with a suitable measurement microphone. Typically the DAC or other interface already used for music playback combined with a USB measurement microphone is all that is required.
Links to suitable measurement microphones can be found on the Resources page.
Focus Fidelity software generates filters saved as stereo *.wav files. Playback software is required to load these filters and perform the filtering.
