AudioTool

I had no problem loading the cal file on my M8 Save to PC first rename then save to tools Dir on phone RTA is great for room tuning Also great for measuring freq response when building passive xovers                 Great with Dayton Mic

Works clean and simple Please note that a phone microphone cannot be considered as reference                

Perfect for what I need THANK YOU                

Ive been using AudioTool since version 351 with a DroidX Im using 623 with a Galaxy Note II and an iMM6 calibrated mic now The app has great features and is accurate Its the best audio analyzer for Android and I recommend it The author is an established expert in the field he wrote the software for several famous Ivie analyzers is very nice and responds quickly My only quibble is that the user interface and graphic design of the app do not match the high functional quality underneath              Best Analyzer Available But Not Perfect

Had to repurchase could not get answers how to switch from Samsung smartphone to Samsung Note 4 Otherwise a great accurate app It also doesnt require access to so many private files like so many other apps 45 u2606              Totally Great except support is by forum

Great flexibility and excellent for engineering diagnostics Microphone calibration options make this a powerful tool for use with an external microphone like the i436 I havent fully benchmarked it against my Type 1 system yet but I will soon Preliminary results look great Valley function needs addressing but everything else looks spot on                 Superb tool

Im a live sound engineer This app is absolutely wonderful and a must have tool                 Amazing

The best sound package I have found so far good bang for the buck but 13d octave calibration is silly the hardware is not very acurate                 The best sound package

Application monitor sensitivity resolution is surprising Samsung S5 microphone appeared not very sensitive until monitoring with this application I am unfamiliar with the significance of most of the data provided Yet rather than being intimidated I am fascinated by the resonate graphic changes reflecting the attributes of various sounds Im inspired to learn the meaning practical application this app Presents              Sound Data

Nice Great tool                 Peak store

Muy Buena Aplicacion para medicion de audio                

Full featured Extremely well done                

I use this app everyday for work Its one of the few apps I paid for and naturally I have had no regrets Just recently I broke my screen and had to replace my phone with less research then Id normally do The developer helped me with minor problems I had with app on my new OS quickly and personally                 Best paid app ever

Works great no issues at all I have it on my Galaxy S5 paired with a Dayton IMM6 I use it for spatial averaging between my drivers and it does a awesome job I just have one request could you make the app icon larger                 Great app

Love this app Helped me out many times at work Just upgraded my phone thought and can no longer access the menu to run calibration or set the screen to always on Droid turbo with KitKat 444             

Worked wonders when used to measure the frequency curve of my android head unit Was able to correct nicely with the built in eq on the unit Great app Just remember the quality of the mic used affects your results                 Excellent

Great set of tools Wish it had memory buttons for savingloading your own quick settings Wish you could change the colors of the spectogram Havent checked this for accuracy but the ability to save and load calibration curves may mean quick calibration no matter what device you have Outstanding app and a must have for any sound professional                 Awesome

This app and its developer are first rate I had a battery draining issue that turned out to have nothing to do with this app and the developer helped me problem solve Top marks                 I use it weekly and love it

Excellent app Great for on the go quick checking                

But dont bother with the builtin mic thats really designed for phonequality speaking Using that this app is little better than the flood of free ones because thats the limiting factor Get a good mic that comes with a serialnumberspecific calibration file and this app becomes about 20dB better than the free ones                 Great for a sound guy

A massive help when used with the Dayton imm 6 mic for setting eq and crossovers in my car I tried to use my ears as much as possible but this helped me identify some peaks in the response that I wouldve missed otherwise                 Great

Use it all the time in the studio on live gigs locating resonances measuring volume Indispensable                

This app is awesome I finally decided to use the RT60 Didnt expect much but it was spot on setting up delay stacks Update Had some small issues with resolution on the app contacted developer and he helped me get it fixed within hours Cant say enough good things about this app                 Perfection

Spectrum analyzer slow after upgrade phone from galaxy express to galaxy s5              Fabulous but

I have a calibrated measurement mic with smaart that I use on all of my bigger gigs This app with the iMM6 is a great pocket sized replacement for the quick and dirty I was previously using another RTA app but having the capability to load in mic calibration files makes this 10X better                 Great app

Awesome to teach acoustics to my students on the field                 Fantastic

Great piece of kit Thanks u263a                

I use it even day                

Been trying to set up active xovers for ages by ear Waste of time get this app and a dayton audio mic for smart phones much betterThanks                 Wonderful

Awesome audio tool for audio engineers Be it live or recording Straight forwards n easy to use Gr8 job guys                 Best audio tool

It does almost everything from your phone I use it with a Dayton Audio imm6 microphone and it works great The only reason I have given it 4 stars is it lacks the ability to record a sweep like many other programs that are at this level              Great App

just the thing to use with that cheap calibrated mike you can buy at Parts Express                

Works great on my Nexus 4 and also on my IPad 2 Handy for using as a quick guide for noise at work before getting the professionals in Many more features than Ill probably use                 Excellent

Love it use it all three time                 Best RTA

The south is probably the firt to the second only f real app on Android at all any other up as a bunch of bullshit this and field recorder the only two apps that are any good at all in a little bit Audio evolution other than that f all the apps                

Excellent audio app especially with the Dayton calibrated mic Many thanks                 Superb

So useful                 Awesome

I use this for live sound engineering on a regular basis Love the calibration features very accurate Lets me see where my mix is at a glance Never crashes Highly recommended                 Great app

Excellent features Easy to use                

Works great with the Galaxy S6                 Best audio tool for Android
