  Johan Van Zyl: Absolutely good apk, can't trust that I can carry this around on my smartphone in my pocket. Very handy program. Microphone calibration file upload would be good. The text on the graphs is little and almost impossible to to read. I revert to double stacking reading glasses or taking screen shots and zooming in.

  Joel Parker Henderson: Works perfectly for impulse response measurements. You do need to understand what these are, and how to use them, on your own. A few recommendations for UI improvements... The save-file dialog should automatically present a keyboard in order to kind a file name. The dialog should provide a default file name such as based on the current datetime. The dialog could disable "Save" when there's no file name.

  A Google user: Was able to produce IR and use to simulate reverb via convolutions with other sample. Thank you. Should you describe what is the "step" plot and how does it differ from the IR plot? Also. Are there any menus to access options. In the apk?

  no name: Works good. Used it in a school project. Got the highest grade. Only thing I don't like is that it starts the measuring as soon as the apk opens. Would be really nice if it started in the "paused" state instead.

  Jonathan Tremblay: Could look into doing Impulse Responses for rooms, having the apk do the same processing but allowing for a longer decay tail to capture a room, with selectable decay time.

  Charles Goran: Can I use the saved files as a source for my IR reverb?

  Bryn Drew: It looks like this apk just generates white noise and compares the input response to the output response. I would have been happier if the apk ran through a discrete set of frequencies and averaged a number of samples at each frequency.

  A Google user: Needs updating. Menu inaccessible -- icon does not present on my smartphone. No crosshairs to inspect dB levels on graph. No method to zoom graph. Cannot search the spectrum output file that was supposedly saved to my SD card. It's refund time...

  A Google user: This does not generate any signal from the speaker. I missed the occasion to refund this. Now I have wasted $2 on a fairly useless frequency analyzer
