iAnalyzer

After having paid for the app with full features in the pre “pro version” past I have lost features due to an “update” download. I'm presently being extorted to pay for features I had paid for and have been deceived into losing. Other than that…

The app is good in its graphic display but lacks an important feature - the ability to rename files. Which are automatically named by the app as you save. The names assigned are just numbers representing the date.

What this app can do is really incredible: * Temporarily store and playback sound with very low latency * Analyze the frequency content of incoming or recorded sound with either an FFT or octave analyzer, in 2D or 3D * Zoom to any point in a recording to bring back the waveform and frequency content There are some graphical rough edges, though. When using the mix mode, with Auto-Peak tracking, the labels obscure the waveform view. Touching the FFT waveform brings up an info box at the top, so you can see the frequency, dB and musical note of the selected region. Very useful. A nice touch is, if you have peak-track mode on, the info box will be highlighted if you roll over a peak. Overall, a technically very impressive app. Things I hope are fixed in the future: * Graphical refinement. The data itself is quite beautifully plotted, but the framing choices are not as appealing. * Zooming in the bottom pane. If I record a very long segment of data, it is difficult to get back to the beginning. * Improved responsiveness with higher FFT sizes, although this is likely a limitation of the hardware, and not the software.
