Hi Everyone,
I am close to delivering a beta release of the measurement application for several customers to test. Assuming this goes smoothly, an official release should be out this year.
The application will be standalone, separate from the filter designer, and available for download free of charge. This application will have everything you need and nothing you don't for taking measurements for digital room correction.
Key features include,
Measurements of left and right channels taken at multiple positions are saved to a single file (*.ffm) which you can open in Focus Fidelity's filter design software.
Measurements may also be exported as *.wav files for use with 3rd party software.
Exported measurements have the microphone calibration applied.
The relative timing of the left and right channels is captured.
The measurement project file (*.ffm) includes microphone calibration and relative timing information, creating a seamless workflow with Focus Fidelity's filter design software.
Audio hardware is accessed via the Microsoft Windows WASAPI exclusive mode interface eliminating issues with Windows audio mixers and sample rate converters.
Measurements can be taken with a correction filter applied. The filter is applied to the test signal the same way it is to music which allows the performance of the filters to be verified.
Tested with MiniDSP UMIK-1 & UMIK-2 microphones and XMOS based USB Audio interfaces.
I have included a pink noise generator tool for setting the volume level.
Future features will include,
Waterfall & spectrogram plots.
Additional channels when required for digital crossovers, including subwoofer integration.
Kind regards,
David
