Analyzer2Go 2.0 is a program running on Symbian S60 3rd generation smart phones like NOKIA N95 (complete list see at the bottom of the page).
It contains several modes to analyze audio captured by the microphone (or from the head set connector)

·        Realtime operation (typically 32 frames per second)

·        Oscilloscope with adjustable trigger level

·        FFT spectrum analyzer including sonagram display

·        Guitar tuner with included high precision frequency estimation

·        CW decoder with envelope and ticker display

All modes can be used with both display orientations.
 

Oscilloscope

The following keys are supported:

<Cursor Up> and <Cursor Down> : change gain
<Cursor Left> and <Cursor Right> : move trigger level
<Enter> : run/stop

FFT spectrum analyzer with sonagram display

The upper half shows the instantaneous spectrum of the audio signal. This trace is coded with every new sweep into colors using the rainbow map at the right border. High levels are shown in red, low levels in blue. This results in a sonagram sometimes also called waterfall display.

The following keys are supported:

<1> : toggle marker
<2> : toggle peak hold trace (light blue) between off, peak and aging
<3> : activate reference trace (white)
<Cursor Down> : change gain
<Cursor Left> and <Cursor Right> : move marker (fine)
<Cursor Up> and <Cursor Down> : move marker (coarse)
<Enter> : run/stop

CW Decoder

The upper half shows the envelope of the audio signal. Symbols are generated using the threshold (white dotted line), which are shown the blue line below the envelope. Theses symbols (dihs and dahs) are then decoded using the famous morse code/alphabet. The text is displayed in red scrolling like a stock market ticker.
The following keys are supported:

<1> : lock speed estimation
<Cursor Down> and <Cursor Up>: change threshold
<Enter> : run/stop

GuitarTuner is a mode identical to the standalone Symbian program "GuitarTuner" also available from Brown Bear Software.
All details can be found on the Brownbear Software GuitarTuner Page

Like a standalone instrument tuner it is able to analyze a tone of a guitar (or nearly every other instrument) and show the note and the mistuning using a pointer and bar display. In addition (which not standard for other tuners) this software shows the input level.
