FuzzMeasure

[aquanaut]

Allows you to see and understand the acoustic properties of audio equipment and listening spaces. By accurately measuring the frequency response of a room or electrical component, FuzzMeasure reveals resonant frequencies, muddy bass, tinny treble and other elusive, qualitative sonic properties. FuzzMeasure allows you to easily compare multiple responses side-by-side, which enables you to make incremental tweaks (moving furniture in a room, for example) and immediately see the difference.

FuzzMeasure’s design makes a highly complex tool very easy-to-use. Whether you use FuzzMeasure as a hobbyist, or you work in the acoustics or audio field, you will appreciate the work that went into making it easier to get your work done. Download a copy and try it out for yourself!

FuzzMeasure 1.3 supports the importing of industry-standard microphone calibration files, and exporting standard FRD frequency response files. Also, in 1.3 you can now average multiple measurement records and apply smoothing ranging from 1/48 to 1/3 fractional octave amounts. Furthermore, you can now take the measurement step outside your computer and capture field recordings using CD players and DAT recorders.
