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. The UMIK-1 is an omni-directional USB measurement microphone providing Plug & Play acoustic measurement. 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. 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:

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] Recall that we applied smoothing to the graph. An in-room measurement has a lot of reflections that create peaks and dips in the frequency response. Above 250 Hz or so, much of this is not relevant to what we hear, so for full-range measurements, 1/3 or 1/6th octave smoothing is generally used. For graphs limited to the low frequency range (up to say 300 Hz), use 1/24, 1/48 or no smoothing. REW: miniDSP worked along with John Mulcahy to develop even greater compatibility for the UMIK-1 inside REW! With the latest beta release of REW (v5.01 and up), the UMIK-1 is automatically recognized by the software and prompted for use when REW is started with the microphone plugged in.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. Please note that OBS is third-party software. miniDSP is not able to directly provide support for this software. For questions or issues specifically related to OBS, please refer to the OBS Forum and its online tutorials.

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. Recommended by our FriendsMount the UMIK-1 into the small stand supplied with it, or if you like, you can use any other microphone stand. To connect the UMIK-1 to your Apple iPad, you will need either the Lightning to USB adapter (for newer iPads with an 8-pin Lightning connector) or the Camera Connection Kit (for older iPads with a 30-pin connector). This photo shows an iPad mini connected to the UMIK-1 via the Lightning adapter: REW: miniDSP once agains partners with John Mulcahy to develop even greater compatibility for the UMIK-2 inside REW! With the latest REW version (Beta , the UMIK-2 is automatically recognized by the software and prompted for use when REW is started with the microphone plugged in. I own some Earthworks M23, M30 and isemCON EMX-7150 as well as the dbx RTA mic, and the aforementioned Behringer. I also regularly use very expensive B&K mics and preamps. For most field work, I use the three Sonarworks mics I own, because they’re good enough for 90% of the audible range and multi-mic measurements are the way forward.
