iAnalyzer is an FFT-based professional application to analyze audio signals. 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 and 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.
