Dayton Audio iMM-6 Calibrated Measurement Microphone for Tablets iPhone iPad and Android
The Dayton Audio iMM-6 is a professional-quality measurement and recording microphone that is designed to work with the entire suite of Apple "iDevices" - iPad, iPhone, and iPod (with 3.5 mm jack). 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 iMM-6 is individually hand-calibrated using a laboratory-standard measurement microphone, for consistent, repeatable measurements that match the level of precision previously offered only by expensive stand-alone microphones.
Dayton Audio's iMM-6 is also compatible with Android and Microsoft devices that use a 3.5 mm TRRS jack. A headphone/line-out is built in for monitoring the recorded signal, and a kickstand elevates and angles the measurement capsule for more direct measurements. Each iMM-6 is ruggedly built with high-quality components. A sturdy carrying case with foam insert is included.
A unique serialized calibration file is available for the iMM-6. This calibration file can be used by most audio-analysis apps for the iPad, iPhone, and iPod Touch (see compatibility list for recommendations). Visit , where you will be prompted to enter the serial number from the case of your iMM-6. After entering the serial number, your download will start.

So if you use have ever used your room correction/calibration with your Surround sound reciever you understand that it makes a world of difference.. but the truth is the calibration mics provided are often a place manufacturers cut costs.. to get the most out of your automatic room correction get this little mic and a trs microphone extension cable.. use this instead and it will capture your rooms reflections much better.. leading to a surprisingly good auto room correction..I have used with AccuEQ and Audyssey and and Ace

at least most women agree (i hope).all jokes aside, I've used this thing to equalize my LS50 meta and pair it with a SB-2000. It's done well so far and the measurements exactly match the ones others have posted online for these speakers, down to 20hz, except the bass gives slightly more jagged results.I've bought japanese microphone capsules before (for binaural recording) that are $5 each that have a flat FR. I also had a old UMIK-1 that broke (my fault) so i opened it and found a 1cm capsule sitting at the nose. I'll try to fix it so i can compare them. so it's not about the size, it's about the quality of the capsule.

I have been using one of these for years. Then I upgraded my phone and tablet to Samsung Android devices. Uh-oh, no headphone jack. I started out with one of the inexpensive usb-c to 4-pole headphone jack adapters. I could not get it to work, until I discovered the trick: you have to plug in headphones to get the adapter (actually a dac and adc built into a connector) to turn on. It worked, but SQ was not great, and dragging around headphones just to activate it was a pain. Then I tried the RDE AI-Micro usb interface. That thing worked right out of the box. Now I can do impromptu testing of live band sound, room acoustics, sound system behavior, etc. I am using the Sound Spectrum Pro App, which has an RTA mode that can run at 1/24th octave resolution. It is an amazing combination.

I lost my first one in a move. I love these, very compact, very sensitive, does a nice job. I use it primarily with their software and in conjunction with system/speaker tuning.
