Dayton Audio UMM-6 USB Measurement Microphone - Professional Studio Recording Mic for PC/Mac, Perfect for Audio Testing, Room Acoustics & Speaker Calibration

The Perfect Companion for Audio Professionals The Dayton Audio UMM-6 professional-quality USB measurement and recording microphone is designed to work with industry-standard third party recording and measurement software. The rugged construction and compact size make it the perfect companion for audio professionals who must work on-location performing acoustic analysis, monitoring audio levels, or recording. Each UMM-6 is calibrated individually using a laboratory-standard reference microphone, for consistent, repeatable PC measurements that match the level of precision offered previously only by expensive stand-alone microphones and measurement equipment. Works great with the Room EQ Wizard software.

A frequency response is related to its "impulse response" (the pressure signal that a speaker or sound system would make if it were fed by an extremely short pulse). Impulse Response The purpose of a Impulse Response is to reveal how the frequency response of a loudspeaker is affected by the room at the location of the microphone. Harmonic Distortion Harmonic distortion is the unwanted addition of new tones to the original audio signal. These distortion products occur at multiples of the original frequency and are centered on the harmonics of the original. For example, a 1kHz fundamental that has been subjected to harmonic distortion will produce energy at 2kHz (2nd harmonic), 3kHz (3rd harmonic), 4kHz (4th harmonic), and so on. Cumulative Spectral Decay A waterfall (or CSD) illustrates, on a 3-D graph, how a speakers' energy decays or is radiated over a range of frequencies. Waterfall plots are used by driver and loudspeaker designers for driver selection, to identify resonances or reflections, and to view driver and waveguide behavior. Automatic EQ The EQ window allows you to customize and visualize the effects of filters based on the measurements taken with the UMM-6 SPL Meter / Spectrum Analyzer The SPL (sound pressure level) meter allows you to measure how loud your source is while the spectrum analyzer shows you the relative SPL of frequency bands. A unique serialized calibration .txt file will be available for your UMM-6. Once you receive your microphone, Visit the Dayton Audio calibration download tool where you will be prompted to enter the serial number found on the base of your calibrated UMM-6. After entering the serial number, your unique calibration .txt file will be available for you to download.
