Audizr Pro Customer Insights

1. As a classical singer working towards full, continuous bel canto sound--without the pitch-scooping often inserted by native English speakers because of the nature of the language, which creeps into the singing of other ones as well--it is great to have a spectral analyzer I can quickly refer to without firing up a laptop and putting that on a music stand.

2. I was happy with the free version but I installed the Pro version just to support the great app.Peak labels float off frequency when app is resumed or after modifying FFT settings and the waterfall fails to draw until the app is restarted.

3. I know I can invert the screen shot in other apps, but it is a hassle.the waterfall feature is terribly buggy.

4. I am excited to see what future updates bring.This is a great tool for checking out your audio system.

5. Only thing I would change is the ability to switch the direction of the readout over time so as to read L to R.By and large this is a good app.

6. UNISTALLING.!!!!! DO NOT WASTER YOUR MONEY WITH THE "PRO" VERSIONFinally I found a spectrum analyzer just for my needs.

7. You should consider adding that featureNice piece of work! Could use one feature though - the ability to calibrate the display.

8. Dayton Audio has a Mic which plugs into Android and IOS devices and for which they furnish calibration data.

9. 3) Some filtering operations upon the original signal.The spectrum options are nice.

10. 2) The possibility to record a sequence of variable length and to be able of playing the saved record.

11. I would suggest some further improvements: 1) The possibility to save a snapshot as either an image file (jpg, bmp, png) or an ASCI one.
