Brilliant I have several audio analysis apps on my phone, & this is the smoothest running out of the lot. The frequency graph is very responsive with one of the highest response rates I have seen. Brilliant work from the developer. Now just need to find out how I can go about using an external microphone with this application.
Good & reliable Used this app for a few things from normal audio checks, explaining noise to the kids & even finding a faulty power supply.
This really is a 5 star app. I (naively) use this app to tune my home stereo & sub. The hope is to set the sub's volume to match that of the speakers, and set the sub's crossover such that the sub is just creating the frequencies the speakers can't. I turn off the sub, then using the peak hold feature and a tone that escalates from 20Hz to 500Hz I create a frequency response curve. This curve shows the lower limit of my speaker's ability. Then I turn off the speakers and repeat the creation of a frequency response curve with just the sub on. I adjust the sub's crossover until the sub cuts off at the frequency where the speakers kick in. Finally, I turn on the sub and the speakers together and, while running the same 20-500Hz tone, I adjust the sub's gain until the sub's frequencies are level with the speaker's.
$6 is a steal Works great on my S2 and Nexus 7. Excellent set of features for the price.
Great Audio Tool Love this app. Extremely fast and accurate. Great for ringing out feedback when doing live sound. Works great on my Droid Razr smartphone and my Asus tf700 tablet.
Wow! This is the best! Simply Awesome! Quickly and dirty tested it with True RTA wave generator and it is accurate on my Samsung GSII (T-mob) all the way from about 100 Hz to 22 KHz! Are you kidding me? This is for mere 5 bucks? I didn't even know cell phone internal microphones can be made to sense a range like this! I didn't test sound levels accuracy, because I don't have a reference equipment. But, I am using this app to determine the probable source of sound and then to find the source, not to measure levels accurately anyway. I tried a few other apps before this one and they don't even hit the ballpark on frequency measuring. Awesome, awesome, awesome!
