Audio measurement software

Here are links to some useful audio measurement software:
Many people rely on the Room EQ Wizard (REW) software. This “donationware” program measures every aspect of room acoustics (e.g., frequency response, reverb decay times, and much more). It also includes a distortion analyzer to measure the distortion of loudspeakers. Coupled with a high-quality sound card (e.g., the Focusrite Scarlett 8i6), REW can be used to measure the distortion of passive components (e.g., capacitors and transformers) and even active devices such as equalizers and preamps.
ARTA software is a collection of programs for audio measurements and analysis in acoustical and communication systems.
ARTA software uses standard and professional PC sound cards for audio signal acquisition and generation.

HOLMImpulse is Non-Commercial freeware with full functionality. There is some discussion of it at and download at

There are other audio measuring programs such as the popular RightMark Audio Analyzer.
