SPL Meter is a professional-grade sound level meter, also known as a decibel or dB meter, for your iPhone, iPad or iPod touch.

Modeled after a traditional analog SPL meter, we have faithfully reproduced all the characteristics and qualities found in those meters, including the ballistics, ranges, filters, and decay rates.

Under the hood we have advanced DSP-based algorithms that meet or exceed ANSI / IEC Type 1 standards. And starting with iOS 6, we can disable the mic filters and limiters, to get the real world performance of a hand-held SPL meter.

And now, upgrade SPL Meter with iTestMic, our pro-grade test & measurement mic, made specifically for iOS devices. Using iTestMic with SPL Meter, you get a calibrated, accurate SPL Meter, that meets industry standards for Type 2 performance. See our website for more information.

But dont compare us to a Radio Shack meter, ours is much more accurate!

We have also included a digital LCD display, as shown in the image, to make this the best SPL meter available for iPhone or iPad. And this is something that the old analog meters never had!

The screen will flip when you flip the phone over, so that you can point the iPhone mic directly at the sound source. (iPhone X does not support upside down mode)

SPL Meter is a universal app -- buy once, and use on all of your iOS devices.

SPL Meter is built by the same team that created the other great professional audio and acoustics apps on the store, Studio Six Digital. Built on the engine of our more expensive "SPL" app, SPL Meters filters and decay rates meet or exceed ANSI type 1. This app is not a toy or a game.

SPL Meter is the one audio app that everyone who works in audio must have on their phone! Not only have we made the best one, but weve priced it so you cant afford not to get it.

*** FEATURES:

FILTERS -- A and C weighting filters are provided.

DECAY -- Choose ANSI Fast or Slow.

RANGES -- 40dB to 120dB in 9 ranges.

CALIBRATION -- Comes pre-calibrated for the typical iPhone or iPad built-in and headset mic, but you can adjust the calibration if you have a professional, calibrated meter to compare it to. Accesses our cloud-based iOS device calibration database, which we updates as new devices are released.

INTERNAL / EXTERNAL MIC -- Select Internal to activate the included compensation filter, which is designed to flatten the frequency response of the built-in or headset mic. External will work with our iPhone Measurement Mic, to be released later this summer. See our website for more details.

SPL Meter is bargain-priced to make it easy for anyone to check out one of our professional, accurate apps. Studio Six Digital is dedicated to making the iPhone and Touch a professional audio and acoustics test device.

Pros and cons of SPL Meter app for iPhone and iPad

SPL Meter app good for

There is some gain problems with this Update. Gain is about 20dbSPL too loud. Can T use it now !!!! ( iPhone 6 )
All features work fine. Compared this to a radioshack SPL Meter at a gig and the iPhone version was consistently within a dB or better. Very impressed at $.99!!
I purchased this to use as a tool for calibrating my new home theatre setup. Its very easy to use just like using an actual sound meter, and seems to be pretty accurate. I have not compared the accuracy to an actual device yet, but judging by the spl chart that comes with it, it looks very accurate.
This app was needed to check out DB levels with dishwashers that proported to be silent at 40DB. So without having to buy expensive additional equipment, I bought this app to check that advertisement. Checking it against several known levels, it appears to be quite accurate, but Im not positive on that. But checking it against those dishwashers I quickly noticed that some were as advertised, some were not. So, I think its worth the price, by far. If you need something like this, try this out first.
I have professional SPL Meters around but this app gives me close enough data that I can trust for day to day tasks. Highly recommended!
I found this SPL to be reliable and accurate for setting up my home theatre. Well done.

Some bad moments

Totally useless will not show the loud end of sound waste of my money, cannot find instructions.
I updated the app to 3.1 and it wont even open. It automatically crashes!!!!!!!!!!! Ahhhhhhhhhh
This is crap! What a wast of money, I know its 99 cent . But its not even close.
Well at least for the iPad three its broken. The meter works fine but when I rotate the iPad it screws up the picture, it kinda just zooms in and cuts everything off, the app has to be used in landscape (sideways) not upright. Bugs that need fixed I guess... Otherwise a very useful tool.
Im not sure why you would replace what was a nice looking app on the iPad with this horrible looking UI. I believe that, in design, form follows function, however, that doesnt mean ignoring form altogether.
Button for iTestMic doesnt work. The page opened gives a 404 error.

Usually SPL Meter iOS app used & searched for

db meter, sound level meter, rta audio, signal meter, decibel meter - sound level meter, and other. So, download free SPL Meter .ipa to run this nice iOS application on iPhone and iPad.
