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.+ Impulse response and RT60 measurement.+ Large font SPL + LEQ meter.+ Lightning-fast FFT with size from 8192 to 65536, giving accuracy better than 1Hz.+ 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.+ No ads!
