RTA (Real-Time Analyzer), FFT (amplitude display driven by Fast Fourier Transform), calibration, signal generators...
Everything is included, bundled in a friendly interface with many on-screen controls and smooth real-time display.
== Features ==
+ FFT (amplitude) and RTA (octave, 1/3 octave, ... down to 1/24 octave).
+ Sound pressure level dBA, dBC, and dBZ.
+ Noise Criterion and Noise Rating in octave RTA.
+ Equivalent continuous sound level LAeq, LCeq, LZeq, LAeq15, LAeq60.
+ Impulse response and RT60 measurement.
+ Large font SPL + LEQ meter.
+ THD+N Total Harmonic Distortion plus Noise
+ Lightning-fast FFT with size from 16k to 1M, providing frequency resolution of 0.05Hz directly and 0.01Hz with downsampling.
+ Sample rate of 48kHz, if supported by the device.
+ Many window functions to choose from.
+ Logarithmic or linear frequency axis.
+ Peak and valley hold with adjustable decay.
+ Highest peak display
+ Adjustable exponential smoothing.
+ Easy pan (drag) and zoom (pinch).
+ Measurement cursors, also used for setting frequency of signal generators.
+ File load/save and full calibration capability, for accurate SPL readings.
+ Signal generators: tone, white noise, white sweep, pink noise, pink sweep, pink octave, pink 1/3 octave.
+ Synchronous measurement mode (including frequency sweep) for clean and fast spectrum analysis.
+ Loopback mode to try out signal generators and window functions.
+ Sharing and printing of screenshots.
