iAnalyzer is originally a FFT based professional software to analyze the audio signals for iPhone, iPod Touch and iPad, now we release this great App for the OS X.
Features:
-High performance software design for Real Time Analyzing(RTA) and complex graph displaying.
-Works on 44K sample rate, 20~20k Hz frequency output.
-FFT spectrum, Octave and 1/3 Octave result display.
-Colored curve depend on the dB value.
-Flex FFT size, 4K, 8K, or 16K.
-Reference Pressure configurable.
-2D or 3D or Mix 2D&3D display.
-History result display while in 3D mode.
-High precision peak frequency computation(average-error < 0.1%).
-Auto peak frequency tracing, up to 3 peaks can be displayed simultaneously and each one be linked from text to the graph clearly.
-Frequency to music scale converter, you can use iAnalyzer as a professional instrument tuner, or to test if any sound is tuneful.
-Drag in the result area to use the measure line, bordered label means where is a peak.
-Current waveform display and summary waveform display.
-Record at any position and red color to mark the latest recording, unlimited recording time.
-Play back the recording.
-Oscope Auto-Scale: Enable you to view more details for low level signal.
-Peak Absorption: Find peak more easily while using measure line.
-Drag in the waveform area or Click on scroll bar to change the current position, iAnalyzer re-compute and update graph automatically. You can also change the position while playing.


How to Use:
-Left mouse drag in the result area to use the measure line.
-Right mouse drag in the result area to rotate the 3D graph.
-Drag in the summary waveform area to move the current position.
-Click on the scroll bar to re-seek the current position.
