Sound Spectrum Pro
A complete sound package for the sound engineer or enthusiast
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 measurements.
- Large font SPL + LEQ meter.
- THD+N Total Harmonic Distortion plus Noise measurement.
- 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.
