Sound Spectrum Pro

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.
• 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.
• No ads!
