SPL Meter
Description
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 don't 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 Meter's 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 we've priced it so you can't 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. Check out our full line of professional-grade audio and acoustics apps: SPL, the professional digital iPhone sound level meter, SPL Graph, for recording SPL over time, RTA, a 1/3 octave real-time analyzer, FFT, for detailed acoustic analysis, ETC, the energy-time curve function, RT60, for automated octave-band decay time measurement, Speaker Pop, to test speaker polarity, and Generator, the iPhone signal generator. Also, if you are looking for more great acoustical and audio test apps, have a look at AudioTools, our premier app for audio professionals.
Andrew's done a great job

What a handy alternative to my hand-held hardware meter, and the readings correspond quite well. Amazingly, the iPhone 7 internal mic enables indication down to 16Hz (organ pedals!) and up to 20 kHz. Developer Andrew Smith's website offers clear description of what spl, dB and hearing-curves are all about. I'm using the SPL Meter stand-alone, but see that it can be mated up with AudioTools to do more.
The best....

....app for spl on the App Store ....and thanks for the update!
Needs to be optimised for iPhone 6
by Black Prophet on 2015/05/12 23:39
Overall not a bad app but needs some improvements. Unfortunately since I've upgraded my phone to the iPhone 6 the buttons on the app seem to be in the wrong place. For example there is a slider at the bottom of the screen which clashes with the apps text! This is basic stuff that should've been sorted with the last update and this still hasn't been done. Sort it out please.
Good functionality but looks poor
by Ems-23 on 2014/10/05 13:50
The app is not updated for retina display, it's super pixelated especially in iPhone 6 and has not embraced the iOS7/8 flat design - functionality 5 starts looks - 5 starts!!!
Needs a digital display with automatic ranges

UPDATE: In the past few versions the low frequency response has been improved and now most likely is as accurate as is possible for an iPhone. On my aging iPhone 3G the low (below 100hz) reads about 4db lower than my Radio Shack meter. It's a great SPL app... I even use it in professional settings sometimes. Thank you for the improvements, Studio Six Digital. --- This is a nice, slick app that is fun to use. For the price, it is impressive. However, it must be noted that it may give highly inaccurate readings at low frequencies using built-in iPhone mic. I tested the latest version on iOS4 on an iPhone 3G using the internal mic. I use slow, C-weighted response. I tested against an analog Radio Shack meter and another $100 meter, and I calibrated the response using broadband pink noise so this SPL meter app read the same as those others. Then I filtered the noise such that I was only hearing noise below about 100hz (low bass frequencies, similar to how you would calibrate a subwoofer). With this setup, the Shack and the other meter agreed within about 2db of each other, but this SPL meter app was at least 10db lower. (using all meters A-weighted, it was closer to the other meters) This seemed like an error in the LF filtering compensation of the app, so I contacted the developer. He responded that iPhone mics are not accurate at low frequencies. The developer claims that this app is more accurate than a Radio Shack meter, but in my experience that does not seem to be the case.
Brilliant app

Easily the best SPL gauge app available. Well done!!
Very very bad

Do not buy it at all it's not working in right way. I want my money back Zero out of 10
Excellent app - a bargain
by Robbie B1 on 2009/12/01 19:41
Very impressive app that offers the functionality of a real meter. I'm delighted to have it at my disposal on my iPhone 3G. Do take note of the comments from the developer about the suite of applications they offer and check out their web site first. It may be more cost effective to buy the package instead of the apps individually
Pretty good!
by Coolnfunky on 2009/11/22 21:05
I've not calibrated this, but from rough estimates it looks relatively close. The interface is nice and simple, intuitive and really easy to use. App seems quite stable too. I like it. Very sensitive as well (picks up a gentle blow at 1 m). Only reason I've dropped a star for it is from a feature perspective. It'd get 5 if it had a capture/note feature. I.e. Capture the measurement and tag a note to it. But that aside, well worth 59p!

If you have multi channel Dolby Digital or DTS at home and your set up does not have auto calibration via a microphone you need to buy this. Mine was way out and now sounds miles and I mean miles better.
Sensitive and Accurate
by FIJ on 2009/06/12 11:53
I needed a wireless sound meter so that i could sit in my natural sitting position and balance the multi-channel speakers. After using this I realized they were previously so miss-balanced. Prob. Only use this once or twice a year but worth it!
SPL Meter review
by SPL User on 2009/06/05 18:02
I decided to review this because i spent a bit of time on the various decibel applications and decided this one looked best for quality of results. It uses an anologue screen with added digital readout and is so easy to use. I use the A filter as this is the standard ratings you will get on noise reports etc. For me it works fine, i cant say that it is acurate or exactly how acurate it really is but i intend to find out in the near future. Grats to the developers and i look forward to future updates for this little app..
Slick!
by Foggy!! on 2009/04/08 23:36
Seems very accurate and is hyper sensitive even to distant whispers. Only addition I'd like to see is to have a resetable display of the peak level reached at a given time. Maybe a digital number next to the other digital readout. For me, that would earn it the final star :)
Works Well!
by seejayess on 2009/03/28 13:48
I'm using SPL Meter on an Ipod Touch 2G with a ThumbTack ext mic and can say it works very well. I have only calibrated against the Radio Shack meter as, not being an audio pro, I haven't access to anything better.

Seems very accurate and is hyper sensitive even to distant whispers. Only addition I'd like to see is to have a resetable display of the peak level reached at a given time. Maybe a digital number next to the other digital readout. For me, that would earn it the final star :)
Works Well!

I'm using SPL Meter on an Ipod Touch 2G with a ThumbTack ext mic and can say it works very well. I have only calibrated against the Radio Shack meter as, not being an audio pro, I haven't access to anything better.

Very good balistics and accuracy A must have for studio applications
Good functionality but looks poor

The app is not updated for retina display, it's super pixelated especially in iPhone 6 and has not embraced the iOS7/8 flat design - functionality 5 starts looks - 5 starts!!!
Crashes

Read the reviews and bought it in great anticpation but it only stays on screen for a second then goes back to the home screen on iPhone 3G

UPDATE: In the past few versions the low frequency response has been improved and now most likely is as accurate as is possible for an iPhone. On my aging iPhone 3G the low (below 100hz) reads about 4db lower than my Radio Shack meter. It's a great SPL app... I even use it in professional settings sometimes. Thank you for the improvements, Studio Six Digital. --- This is a nice, slick app that is fun to use. For the price, it is impressive. However, it must be noted that it may give highly inaccurate readings at low frequencies using built-in iPhone mic. I tested the latest version on iOS4 on an iPhone 3G using the internal mic. I use slow, C-weighted response. I tested against an analog Radio Shack meter and another $100 meter, and I calibrated the response using broadband pink noise so this SPL meter app read the same as those others. Then I filtered the noise such that I was only hearing noise below about 100hz (low bass frequencies, similar to how you would calibrate a subwoofer). With this setup, the Shack and the other meter agreed within about 2db of each other, but this SPL meter app was at least 10db lower. (using all meters A-weighted, it was closer to the other meters) This seemed like an error in the LF filtering compensation of the app, so I contacted the developer. He responded that iPhone mics are not accurate at low frequencies. The developer claims that this app is more accurate than a Radio Shack meter, but in my experience that does not seem to be the case.
Brilliant app

Easily the best SPL gauge app available. Well done!!
Needs a digital display with automatic ranges
