Best of it's class I recently installed and evaluated at least 6 (I didn't keep exact count) apps that are competing with this app. I found that this app delivers the feature set that I was looking for in addition to being well executed in terms of stability and user interface. People reading this review may have feature set requirements that differ from mine, so YMMV. I particularly appreciate the zoom and scroll capabilities. Quite often I want to use the entire screen width to view a narrow slice of spectrum in order to re
Great tool Nice app. I use it occasionally has an Audiologist. It checks out well against tuning forks (within 4Hz). It does need an easy way to save images to the gallery, though. Highly recommended. 7/2014: Rating increased to 5-stars since the "save to gallery" issue was fixed. Thanks! I can actually save the images and export them to our EHR database to upload into a patient's chart for reference. Geektastic!
Good start Basic functionality good. I'd really like a save option for a csv file with the data in it as well as image. I also occasionally get an 'error opening audio' problem on Galaxy s5. Small nerd point-fft can only be done on power of 2 length samples yet you can set the value to anything. Are you padding the input data with zeros? Might be best to stick to 256, 512, 1024 etc.?Happy paid for app, price fair for functionality.
Good value for the money. I had read the other reviews and downloaded. I needed a analyser to investigate a high frequency. I did not have my normal professional one to hand. I was surprised at how accurate it was. I used it to investigate a area where customers were saying they could hear the Surveillance tone from our voice alarm system. Our tone is at 20 KHz so I thought this would be very unlikely. I used this program and found a 18 KHz tone present that was not generated by our system.
Made in USA! After reading reviews for the other apps, I felt this one was the safest. Shows the sad state of Android when we install based on least-potential-harm rather than benefit. Worked fine and a decent interface a well. Good job and hope it makes you a million:-)
Cool, I just want to add, I tested it against a real audio spectrum analyser. It's so close to the grass speck, I was totally blown away. I have Samsung's Galaxy Light phone. Good job sir. And thank you for thinking out of the Box.
