Dayton Audio iMM-6 Calibrated Measurement Microphone for iPhone, iPad Tablet and Android,Black

Not only is it great to get a calibrated measurement microphone for such a low price, but add in the fact that you can easily access the calibration curve for your particular microphone by inputting the serial number into a website listed in the manual, and you now have yourself an amazing piece of professional quality audio testing equipment that is unbeatable for the price. Upon receiving the package containing my microphone and some other items from Parts Express, I was immediately able to recognize that the microphone did not come in a cheap bag or box type package, but rather came in a nice brushed metal tin with a firm foam lining that fit the microphone very snugly. This case is suitable for long term storage of the microphone, and was a very pleasant surprise. It is also a great size for carrying just your phone and the microphone around in a pocket or two in order to do audio testing on the go. The microphone not only has a great rubbery feeling matte finish, but it also has a very high quality enclosure with no noticeable ridges or gaps such as many cheaper molded plastic items have. This rigidness is likely a large factor in the amazing quality of the microphone. When testing, even when holding the phone in my hand with the microphone hanging from the jack, facing an audio source (my new low cost studio monitor speakers that I am evaluating as well), I noticed no handling noise, and no static or crackles as a loose connection would indicate. The jack on the mic is also of good quality and has nice alignment so it does not stick out from the phone (or computer) at an odd angle. Using several free apps, I was able to utilize my iPhone and this microphone as a small audio testing station of sorts. With an audio sine wave sweep generator, and a frequency response app, I was able to look at how flat my speakers were with the position that they were in, and I was also able to detect how directional they are at high frequencies. I needed this microphone for an engineering project I am working on (studio monitor speaker isolation stands), and this saved me probably over a hundred dollars compared to buying dedicated audio testing equipment. Another wonderful feature of this microphone is that it offers a headphone through jack so that I can still play music or audio test signals on my phone while using the microphone with an audio analyzing app. I can also monitor the audio coming in when using certain apps. The mic can handle very high SPL without distorting, and overall I think that it is a great item worth purchasing for any audio enthusiast. If I were to lose the microphone or break it, I would buy another in a heartbeat.

Works great, and the results match other calibration tools in my home theater. Also assisted in calibrating a commercial live-audio installation. Audibly helped the commercial system and I could easily visualize the changes. I would advise you to use an averaging tool in making the measurement (AudioTool has this option) as instantaneous reading of pink noise is not the easiest to see what is happening. For the purpose of doing frequency calibration of a stereo system, seeing the average of pink noise results is more helpful, and then use instantaneous to dig out things you hear or see. Who all those who blast this as: "This is a horrible microphone, my built in one is better" and the like, I'm sorry, but you have no idea what this microphone is for. You think this microphone is supposed to sound good, thinking that it has build built with "calibration". This is not a high-quality microphone (measurement-grade microphones don't come under $20, if even $200). This microphone has nothing fancy inside it. This is, however, a microphone what has been measured at a shiz-ton to frequencies to characterize the microphone's frequency response so you can have a reference point as to what you are measuring. Even if your reference is crappy, if you know what it is, you can make use out of it. What's the difference in amplitude between 4kHz and 30Hz on your iPhone/android's microphone??? You don't know. Even if one was measured for calibration offsets, do you really think every single unit will have the exact same response down to a dB? It MIGHT give you a ballpark... maybe.... if it's a full moon... wearing green??. Sorry for turning this into a rant. I just hate seeing an awesomely useful tool for <$20 that does what a RANE calibration system does for $500+ get blasted as being a crappy product. A wrench does a pretty lousy job of spreading peanut butter on toast-- if you use a tool wrong, you will likely get bad results.

This is a great value and very useful microphone. You can download a device-specific calibration file from Dayton based on your serial number. I bought this to use with a real time analysis program on my laptop that has a TRRS connector instead of separate headphone and microphone jacks, which is more common these days. With the headphone out jack you can send test tones through the auxiliary input of your system. I used it in my car for audio system calibration. I used True RTA software but you can also get REW. I also purchased a mic/headphone Y splitter cable (StarTech MUYHSMFF 3.5mm 4-Pin to 2x 3-Pin 3.5mm Headset Splitter) to loopback for system calibration, and a long 3.5 mm auxiliary cable for plugging in to my system (StarTech MU6MMS Slim 3.5mm Stereo Audio Cable - M/M, 6 Feet STARTECH.COM ) and an extension for flexible microphone placement (StarTech MUHSMF2M 2m 4 Position TRRS Headset Extension Cable ) All for less than 40 bucks and you have a high quality RTA system. Worked great in my car and picked up the factory crossover points in my speakers. Microphone works in my Windows Phone as well, but there aren't many useful RTA programs like Audio Tools for WP. Too bad, it would be a great tool. Loading the calibration file into the iPhone is a joke. Edit: FYI There are now Windows phone RTA apps available but I haven't yet tested with the microphone.

This product seems to work great. I use it with some of the recommended apps on their website. I would give it 5 stars if I could get more support from other audio apps. It comes with a calibration file you download from their website that is unique to the serial number on the box. Load that calibration file in with the audio app (if it supports it) and you are good to go.

For the price, this microphone is great! I have used it to tune multiple vehicles since I got it. I use it with REW on my laptop and it works flawlessly. This is my first calibration mic, but I have done a lot of research online and there is nothing but great reviews on this mic. There are better out there, but not for this price point. Great entry level product for people getting into audio.

I bought this to calibrate my dual subs in my home theater. This review doesn't contain any useful info, just a description of my utterly confusing experience using it. Basically, just a warning for people who never did any kind of calibration and unfamiliar so you'll get some idea what to expect if you order this. But here's the problem. I guess this is designed to be used with Audiotool only. It's free if you have Prime, btw, just use Amazon Underground App. It will contain ads. They will pop up every 10 seconds offering you some card games. But I'm very happy I didn't pay $7 for that, it's not worth it just for basic testing using your AV receiver. My 1st question, why doesn't Dayton let you download .cal file right away? Why have it in .txt and then have us rename it? What's so hard in just have us download it in .cal? On top of that, neither Dayton nor Audiotool manuals specify how to activate this mic. You plug it in, and then what? Does it become the working mic automatically or are you supposed to activate it by choosing Front or Main mic in the settings or something else? I don't know. By doing the "put the finger over the phone's mic and see if charts drop off" test I figured it was on at "Main" setting, because I think... I THINK the charts went down a bit, but I'm not sure? With pink noise the frequency bars in Audiotool jump so much it's impossible to tell the difference (say, from 30 to 50, randomly)... Then I went on to test my subs. My room is untreated, so with this mic in or out I didn't see any difference in levels (Motorola Moto G4 Play phone) down low. There was no +/-3dB variation on the charts, nothing like you see in those smooth graphs online... With my dual Klipsch SUB12 I saw 45dB at 31Hz, up to 60dB at 62Hz, and all the way up to 80-90dB at 80-90Hz. Plugging it in and out didn't reveal any variation or change the overall shape of the freq response in any noticeable way. So my conclusion as a user who has very little idea what he's doing is this: either your phone's mic is accurate enough for simple testing like this and there's no point in buying additional microphones or this mic simply wasn't working. I can't give this 5 stars because I don't even know it was on, but I can't give it 1 star either ecause, well, I don't know if it was off. I wish there was an option of not rating at all... I think either Dayton or Audiotool guys should've provided some clear instructions how to use this because not everyone is a sound/phone engineer with 20 years of experience.

I used to compulsively carry a Zoom around with me to capture found sounds for my electronica. The thing was never that heavy, but my spouse and friends would tease me. In addition I'd always get more attention than I liked when I used the Zoom in a populated area. I stopped carrying the Zoom around with me and eventually sold it. I regret the many tasty sounds I've missed recording. Like a lot of geeks, I carry an Android phone with me (Galaxy S4) and no one teases me for it. This microphone fits in my pocket and I can carry it everywhere. I use it with an app called RecForge II that lets me tune my gain as well as disable Androids dynamic gain. I did some recording with the iMM-6 of some sounds: egret squawks along the slew, Starbuck's coffee shop, street noise, my dog vocalizing and a small water pump. I compared them with similar sounds that I captured years ago with the Zoom. It compared well. The noise floor was not as low with the Android. I was pretty happy with the range of frequencies I captured. For example, the steam from the expresso machine sound real and the egret croak was great. The thump of tires over a bridge was pretty cool. Since the microphone is paired with a calibration file on the Dayton Audio website, it made setting a default eq quite easy. I don't consider any of these things to be a fail. Instead I'm really happy that this low cost microphone did so well in this application. This isn't a pro audio recorder, but it works extremely well as a stand-in for one. Unfortunately, my spouse still teases me. However, when I've used the mic in public places no one notices. Because my cans are plugged into it, they probably think I'm just listening to tunes.

For those of you looking into purchasing this mic for recording purposes - that is NOT what it is designed for. This is a measurement mic, used for analyzing acoustic environments. Is this mic and a free-to-inexpensive mobile app going to give you the same results as a thousand dollar Earthworks measurement mic and a laptop-based Smaart rig? No, of course not. But for $22 it does a very respectable job. For less than $50 you can get this mic and a copy of AudioTools and have a very effective way to handle all of your basic analysis tasks. This is a no-brainer purchase for anyone needing a very portable audio analysis setup.

Cercavo un microfono di misura (analisi audio) da poter usare su dispositivi mobili. Mi sono imbattuto in questo su youtube e per curiosità l'ho ordinato visto il prezzo molto accessibile. Il venditore mi ha contattato per avvisarmi che la consegna sarebbe avvenuta in anticipo e l'ho apprezzato molto. Per ogni microfono c'è il file di calibrazione da scaricare tramite il codice dietro la scatolina (in metallo). Si possono fare comunque misure senza file di calibrazione ma, caricandolo la misura è notevolmente più precisa. Sono soddisfatto e credo che acquisterò anche quello per standard. Consigliatissimo per i fonici che non hanno sempre un setup "ottimale" con cui poter analizzare gli impianti.

I bought this to take some measurements to try some room correction software. My latest smart phone has USB C, but I have an old phone that has a audio analogue connection so I thought I would save some money, in case I wasn't impressed with the improvement. Downloading the software for the Dayton calibration was straight forward from their website, as was adding it to the room correction software. When setting up it is important to stabilise the phone at ear level to get the best results. I was very impressed, as it highlighted the dip in the frequency curve where I expected it. I decided not to implement the changes the room correction programme recommended, as I could if I wanted to, adjust just as well using digital EQ, the changes were not so big. All in all a good experience, be aware it may not work with all phones or tablets, as I found with an old LG flagship phone. Highly recommended, well made, well packaged and quality product with great capabilities.

Très bon produit. Attention, sur la plupart des smartphones, devient inutile car les tel Android ont des filtres internes

Das Imm-6 macht auf mich einen wertigen Eindruck,- meines Erachtens eine hochwertige Verarbeitung!! Es macht was es soll, Messergebnisse liefern!! In Verbindung mit der Kalbrierungsdatei und Android Audiotools scheint es mir als Privater Böxlebauer für meine Zwecke völlig ausreichend!! Ich kann hierfür (vor allem für den Preis) wirklich gern 5 Sterne vergeben!! Dayton eben ;)) Ps. Ich habe nun mal nichts zu bemängeln, entspricht völlig meinen Erwartungen, warum dann weniger sterne geben,- es ist wohl nicht der Daimler-Benz unter den Messmikros aber das war mir vorher klar.Bei diesem Preis kann man nix falsch machen!!!

É um bom produto
