miniDSP UMIK-1 Omni-Directional USB Measurement Calibrated Microphone

Product Information

The main measurement plot shows a frequency measurement graph in red. At the left is a small "thumbnail" version of the measurement - each time you make a new measurement, a new thumbnail will appear here. At the top of the screen are buttons that access various tools and immediately above the measurement is a row of tabs that show different "views" of the measurement. The UMIK-1 is an omni-directional USB measurement microphone providing Plug & Play acoustic measurement. For multichannel system (E.g. 5.1/7.1) or a surround application where multiple speakers are spreadout around the room, use the 90deg file and point the UMIK-1 at the ceiling.

Last but not least, miniDSP partnered with Dirac Research for the design of a VST plugin specifically calibrated for the ambiMIK-1 with over 1200 measurements. The controls include Yaw/Pitch/Roll/Output gain and Output Format (B format or Binaural). Features The Options screen can be used to set options, such as octave or third-octave display, frequency weighting, response time, and whether or not the display scales automatically.

You're now up and running with the ambiMIK-1 streaming into OBS. Next stage is to configure the Dirac Live VST plugin so we're converting the ambisonic signal from the 4 mic capsules to a binaural signal one can enjoy with a headphone. 3. Configure the ambiMIK-1 VST plugin [Top] Tap on Sig Gen at the bottom of the screen. You can experiment with the different types of test signal here. For now, set it as shown below, adjusting the volume so that it plays through the system at a comfortable level. Ensure that the signal generator is enabled at the top right, and turn signal generation on and off with Play/Pause button (next to the Headphones label at the top left. Adjust the level with the iPad volume control and the Noise Amplitude slider, and use the Noise Pan control to send output to only one speaker. NOTE: if you can't see the miniDSP ambiMIK-1 VST from this list, it's most likely because you didn't copy over the VST files in the correct folder as it will search the plugin in the following folders. Make sure to copy the VST files into one of these folders.

Upon opening SignalScope Pro, it will detect the presence of the connected UMIK-1 and query you for its serial number: For OBS to be able to support the 4 ch USB audio interface from the ambiMIK-1, there are few settings to be configured first. To make sure the below steps are running smooth, make sure to connect the ambiMIK-1 to your PC/Mac before going further. Dirac Live: As a well known reference in the world of room correction with countless high end audio/automotive, we're honored to have Dirac as part of our partners. The UMIK-1 is the recommended microphone by Dirac Research.Special features such as calibrated SPL measurement enabled under free Room EQ Wizard (REW) software Then open the Configuration screen (the "gear" icon), and tap on I/O Device Configuration and then Input Channels. You will see the UMIK-1 has been selected: Umik-1 on Ipad: Our technical team has been testing the UMIK-1 along with few ipad apps. A plug&play setup for a full featured measurement + SPL meter running from the Ipad. Finally, change the signal generator to generate a pure tone (sine wave). Then go to the FFT display and tap the Play/Pause button. The display will show the tone being generated as a high "spike" as well as any distortion components. (For example, if you play a 1 kHz tone, distortion components will be at 2, 3, and 4 kHz): For multichannel system (E.g. 5.1/7.1) or a surround application where multiple speakers are spreadout around the room, use the 90deg file and point the UMIK-2 at the ceiling.

miniDSP offers products that can be used to equalize a system or apply full-range room correction, such as the nanoDIGI 2x8 (digital in-out, parametric EQ), miniDSP 10x10 HD (multichannel analog in-out, parametric EQ), and OpenDRC-DI and OpenDRC-AN (digital or analog in-out, FIR filtering and room correction). Note that equalization for room correction should generally make use of multiple measurements over the listening area, as measured response will change with microphone position. DSP equalization can't change reverberation time. Heavy drapes and carpets will reduce reverberation time, but if you need to go further, then dedicated acoustic treatment may be required. How did you position your microphone for each measurement? Just asking because the highest frequencies will be most sensitive to small differences in where the microphone is located.Based on another thread it might also be that your signal level is a bit low for the UMIK-2. Are your results repeatable? In this application note, we will show you some basic acoustic analysis techniques that you can apply to measurements of your listening room made with the UMIK-1 and Room EQ Wizard (REW). REW offers a set of plots that show how different frequencies decay in time. These are generally used in the "modal region" of the room's acoustic response, from say 20 to 300 Hz, where resonances in the room dominate the measured frequency response. A well-known plot of this type is the "waterfall" plot, or cumulative spectral decay: miniDSP assembled some very comprehensive steps by steps for the UMIK-1 for all sorts of applications. Please make sure to start reading our application notes to be up and running in no time!

Combined with our recommended acoustic measurement software, it is the perfect match for a plug&play measurement system. Why is the graph so uneven? Shouldn't we have a flat frequency response? Mostly, it's because of the room. Room modes (resonances) and reflections in a room act to make a nice flat loudspeaker response into a roller-coaster. Please note: miniDSP cannot provide support for third-party applications or hardware. This app note shows you how to set up the miniDSP UMIK-1 to use with SignalScope Pro but other functions of the Apple iPad or the SignalScope Pro app are beyond the scope of miniDSP support.The UMIK-1 is an omni-directional USB measurement microphone providing Plug & Play acoustic measurement.

Features The miniDSP UMIK-1 is the perfect companion to audio analysis programs running on your tablet or even your smartphone. In this application note we will show you how to set up your UMIK-1 with the SignalScope Pro app from Faber Acoustical, running on an Apple iPad. SignalScope Pro is able to set level and frequency response readings (FFT only) from the UMIK-1 calibration data. Did you definitely have the correct calibration file for the orientation of the microphone in each case? Getting this wrong for one of the microphones could cause this sort of difference I think. At this stage the steps to start your YouTube/Facebook/Twitch Live stream or recording a local stream will be similar to any stereo content. If you're not familiar with setting up OBS for Youtube/Facebook live, we recommend you follow some of the great step by step guides to get you started knowing this is a common question. Here are some great examples: Make sure to configure the plugin to binaural audio output. See the ambiMIK-1 manual for other settings you might want to modify. You can easily confirm that the VST plugin works as it should as only 2 channels will now become active under the Audio Mixer.
