AudioTools - dB, Sound & Audio App Reviews

I cannot tell how accurate the measurements really are due to the surely limited capabilities of the built in iPhone 3GS mic, but at least these SW tools offer me possibilities which I otherwise only get on devices that cost many 100 €. For a long time Ive been looking for something like this for measuring the party rooms with pink noise. Even if the measurement is not accurate, it gives me a quick overview of the spectral signal response and in turn this tells me how to setup the equalizer. Apart from that, I can easily identify the feedback frequencies caused by the wireless microphone. And not to forget the SPL meter that helps a lot, not to exceed a certain SPL in critical locations. Definitely worth the mony! I will probably also by the optional modules.

Works very nice and looks great but the i/o capabilitys of the iphone are limited. Would like to have the ability to stream audio via WLAN to the iPhone in realtime so one could use it via wormhole or aunetsend plugins within the DAW and with high quality i/o of the main computer. That would make it a killer tool!

It is defenitely a nice tool and very helpful, BUT basically only if you buy the additional modules/plugins. The free tools are good for very basic measurements. Actually, I didnt expect with regards to the base price the capabilities to be that limited. So if youre thinking of purchasing the tool, make sure, that this is what you are need. The (very powerful) impulse response module costs More that 40 €! Additionally! Compared to other equally complex or powerful apps (e.g. GarageBand) you have to pay a lot, especially for the whole bunch of modules. And: It is still not stable. While testing the apps, I had a few unexpected "shut downs". Finally it is a powerful, not yet fully stable and unfortunately expensive tool! I strongly recommend to check out thier site, before you decide to purchase.

I use it for some time and find it great to have some good bunch of measurement and calculation tools right in my pocket. Price is high cpared to common apps, but this is made with a professional goal and interest, so for a mini ressource pro tool its fine for me :)

You cant use the test tone generator simultanious with the analyzers. Reallynbad for an app with sucha price tag. I feel once more ripped off by apples buy before try system because that allows the developers to sell such flawed apps.

I buy this app, expecting some useful tools, but instead it includes just the developers CHEAPEST apps. So, I feel like I could take my $20, and spend it on each individual thing that came with it, and come out with change leftover. ALSO, in the screenshots, it shows apps that dont even come with it, you have to pay an extra $8 for. what a load of crap.

The apps are accurate. The Modular audio toolbox concept is very nice. I greatly look forward to the future Of this app, especially impulse response creation! Ignore unprofessional naysayers, this app is good. Keep up the good work.

Nice program. Keep up the good work guys.

Nice app.. would be nice if some basic things like the digital SPL meter and tone generator were included in the $20 purchase price.. The box itself is very nice, still have a bunch of testing to do, but so far, so good

I setup a friends stereo in his garage with this app. I got him to purchase it aswell once I showed him the RTA and DB Meter (he loved the app too since he is a professional musician and this app can help when he sets up for his gigs). But in his garage, the surfaces of everything was so hard that the sound was irritating! So we dialed in each frequency of the EQ (little 7 band). He hooked up his iPhone through the stereo and using the Signal Generator he set each frequency to the band of the EQ (the EQ was set completely flat for the baseline test). I went to the middle of the garage and measured the SPL with my iPhone. Once we knew the base SPL of each band of the eq, then he again applied the frequencys throught the stereo and we adjusted each band (one at a time) until the SPL was the same on each band. Now you can stand anywhere in the garage and it sounds fantastic. We adjusted the response of the system in the room and now is completely balanced and the clearity is unreal! There are no harsh tones and has fantastic stereo seperation. It worked so well there is only about .5dB loss from one end of the garage to the other. Im currently looking for dual mono 30 band EQs for myself just so I can fine tune my home audio system with this app. I have also used it to tune my bass guitar (adjusting the pickups) so the volume of each note is within about .5dB of each other. I have tuned car stereos, setup for friends gigs, etc. If youre an audio nut, you will love this app! Keep up the great work guys!

Fantastic app and the additional in-app purchases have been stunning! Five years ago this set of tools would have cost thousands of dollars AND you would have needed a vehicle to schlep it around - now an iPod Touch & a pencil bag for the mic and pre and your set. Im amazed every time I use it - all this ability & accuracy in the palm of my hand... Cool. Andrew keep up the great work. Ill be downloading the STC in-app as soon as iTunes lets me. Looking forward to SII app. Last words... For those people that gave negative comments about spending 20 bucks and not being happy with it. Youre ignorance and obvious lack of age is showing. Sonny, this app is way too big for you.

An amazing suite of tools. Super professional. I am demonstrating sound and audio measurement principles to my students in a technical theory course at University. I could lug all the big expensive gear in the room, shoot the meters with a video camera and project that onto the big screen, or...simply plug my iPad into the external VGA connection (with the VGA adaptor) and, voila! Real time analysis. I like that I can use the generator on my iPhone and display the results on the iPad. Keep up the excellent work, people!

One of the best tools I have

This is a super app! I can replace an entire cart of instruments with my iPhone! I do agree about the user interface. The graphics, icons and overall visual presentation of the software does not do its superb functionality justice. Andrew, you should hire a graphic artist to make this app look as good as it works. For those complainers out there, you apparently dont know what it costs to own all the separate instruments that this app replaces. Keep up the good work Andrew. Your prices are fair considering what it cost me to purchase the instruments that this great app is now replacing! It blows my mind how I can carry an entire lab cart of equipment in my pocket now!

It astounds me that I am able to conduct detailed site surveys, technically support what I hear or do - without bringing in the rather large tool box of specialized equipment. Its all in the app! And the extra purchases are also a fraction of what they would cost in the pro world. I like the fact that the app designer is also CTS certified as there are some criteria to truths we are committed to. So the promises for continual upgrade are undeniably real. My sincere thanks to those who have shared this valuable intellectual property. It has helped greatly.

Get rid of annoying startup screen.. Would like to see a better icon and user interface. Just hire a professional graphic artist guys... Some apps could be combined, but instead are bundled as add ons; I would rather not keep having to press the back button every time I want to use a different feature... For example all of the Spl meters could be lumped together. It is a little tedious and I cant help but feel cheated. It would also be nice if the resolution was higher because it is a little pixelated on the iPhone 4. Go ahead and buy it, but let the developer know that it needs updating.

I use These apps with the iO interface 2 on my iPhone. I took time to compare various output data directly with my long time existing measurement system (EASERA, laptop and RME FFUC) and while a few of the calculations seem to not behave, most of the data is totally great. Studio 6 seems to be very busy improving the apps all the time and given the very low cost and exceptional convenience, I very highly recommend AudioTools and the interface! I may get the i test mic also. I use this gear professionally in my acoustical consultancy... Not on all projects but much of the time these days!

very good application accurate and complete, fast technical support and efficase, really the cheapest for analysis 1 in all with an interface, its amazing

Great portable AudioTool Set. Keep up the good work Andrew ! Thanks Don
