You can now run as many more measurements as you like! If the environment is noisy, set the "Synchronous averages" to a number greater than one in order to average the signal from several sweeps and improve signal to noise ratio. Turn up the system volume until the sweep is loud enough to halt a conversation, but not so loud as to be uncomfortable or to sound distorted. You should hear a faint sweep from low to high frequencies through the selected speaker. Position the UMIK-1 where you want to take the measurement, and point it towards the speaker being measured.Ĭlick on the + button to view the Measure screen:Īs long as you have turned the volume down, you can click on the Measure button (the red one with the triangle). Note that both input and output operate at the same sample rate, so the output device must be able to operate at 48 khz (almost every device will).īefore proceeding, turn down the volume on your preamp or A/V receiver to a fairly low level. Under Record Channels, drop down the selector for channel 1 and select "miniDSP UMIK-1.".If you have selected a stereo output device, select channel 1 for left and channel 2 for right.
In this example, it is set for HDMI channel 3.

SPL calibration from the UMIK-1 calibration file is expected in a future revision of FuzzMeasure Pro 4. Acoustic measurements will be correct but the absolute SPL readings in FuzzMeasure's Sound Pressure Level frequency response display will not be correct. Note: In its initial release, FuzzMeasure Pro 4 doesn't support absolute SPL calibration based on the sensitivity figure in the UMIK-1 calibration file. Click on "+ Add Calibration Record" at the bottom left and select "Import UMIK-1 calibration.".įuzzMeasure Pro will fetch your UMIK-1 calibration file and display it: From the Window menu, select Microphone Calibration. Now load the calibration file for your UMIK-1. The toolbar across the top has several handy buttons that we will use below: For acoustic measurement, "Classic" works well, although you can change or customize this later. You will given a choice of several templates to choose from, which display different combinations of measurement graphs. This photograph shows the UMIK-1 connected to a MacBook Pro and a Mini DisplayPort to HDMI adapter cable for audio output: Your Mac's optical digital audio output connected to a DAC or A/V receiver.The inbuilt analog line output with a 3.5 mm to RCA adapter cable.
You will also need to connect your Mac to generate audio output through your system. Connect the UMIK-1 to your Mac using the supplied USB cable. Mount the UMIK-1 into the small stand supplied with it, or if you like, you can use any other microphone stand. For Version 3 of FuzzMeasure Pro, please see this app note. Note: This app note describes the use of Version 4 of FuzzMeasure Pro, which requires Yosemite (OSX 10.10) or later.
