![]() ![]() 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. Under Playback Channels, select the output channel that you want to send the measurement signal on.The sample rate will automatically change to UMIK-1 sample rate of 48000 (48 kHz) if it was not already. Select the UMIK-1 as the Record (input) device. ![]() Select your Playback (output) device ("HDMI" in this example).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. In this app note we will show you how to get started with the UMIK-1 and FuzzMeasure Pro. FuzzMeasure Pro automatically downloads the calibration file for your UMIK-1 based on its serial number. FuzzMeasure is one of the many helpful tools I use to do my job effectively.FuzzMeasure Pro (V4) is an easy-to-use acoustic measurement program for Apple Mac computers. Before FuzzMeasure, I did all this by ear. A lot of clients just want you to tune the room fast and FuzzMeasure has definitely expedited the process.Ī lot of mastering engineers don’t do their own room scans however I feel that you have to know how to do your own work in case something gets accidentally moved or bumped. I'm not the guy designing rooms on a piece of paper, but I can tell you if a room sounds good or not. I’m not a trained acoustician, I’m an audio engineer. To be able to show both the Waterfall and Reverb Time (RT60) graphs at the same time, without having to close one and then open the other, will save a lot of time as far as them grasping the scope of problems in the space. FuzzMeasure is simple and affordable - the kind of tool that will empower the next generation of designers, consultants, and researchers. Architectural acoustics is more complicated than it should be.
