· Thanks to Ozneb, who added a Sonagram display, and the ability to switch between multiple instrument configurations.
· Allow install to SD on Android 2.2.
· Some improved error handling; maybe fix a crash some folks are seeing.
· Fixed a bug where a spike was displayed at 0kHz.
· Fixed block size setting bug.
· Maximum sampling rate is now 44,100, so frequencies up to 22kHz can be sampled. Smallest block size is now 128 samples, which results in 64 frequency bins.
· Lay out the gauge labels better on QVGA / HTC Tattoo.
· The windowing function in use is now selectable, including no windowing.
· Use windowing to improve the spectrum analysis. Also fixed a bug with text blacking out in the about box when scrolling, and added helps links to report bugs etc.
· Added help on interpreting the output.
· Better help facility. The spectrum graph now doesn't auto-scale, but has a log scale.
· The audio input settings such as sample rate are now configurable. A performance stats display is added. From this version on, 0.6dB is added to the power level, to make it possible (though hard) to get a zero value.
· Better display, with a grid/frequency scale on the spectrum display. Using a much faster FFT.
· Better screen layout, Android 1.6 version. Added keep awake option.
· Dynamic screen layout, Android 1.5 version.
