2. Spectrum analyzer - Wikipedia

   en.wikipedia.org/wiki/Spectrum_analyzer

   The display of a spectrum analyzer has frequency displayed on the horizontal axis and the amplitude on the vertical axis. To the casual observer, a spectrum analyzer looks like an oscilloscope, which plots amplitude on the vertical axis but time on the horizontal axis. In fact, some lab instruments can function either as an oscilloscope or a ...

3. Real-time analyzer - Wikipedia

   en.wikipedia.org/wiki/Real-time_analyzer

   A real-time analyzer (RTA) is a professional audio device that measures and displays the frequency spectrum of an audio signal; a spectrum analyzer that works in real time. An RTA can range from a small PDA -sized device to a rack-mounted hardware unit to software running on a laptop .

4. Low Frequency Analyzer and Recorder - Wikipedia

   en.wikipedia.org/wiki/Low_Frequency_Analyzer_and...

   A new system installed in 1973 began a general upgrade to full digital signal analysis that continued into 1981. That system, using a high capacity digital computer, fully digitized the spectrum analysis and had some automatic detection of acoustic signatures. The system of electrostatic displays was not replaced by digital displays until the ...

5. Smaart - Wikipedia

   en.wikipedia.org/wiki/Smaart

   Smaart running as a spectrum analyzer, in spectrograph view. In spectrograph view, Smaart displays a real-time spectrum analysis, showing the relative strength of audio frequencies for one audio signal. Needing only one channel of audio input, this capability can be used for a variety of purposes.

6. Audio analyzer - Wikipedia

   en.wikipedia.org/wiki/Audio_Analyzer

   Audio input stages that receive a response from the DUT, both analog and digital, and convert it to appropriate signals (analog or digital) for analysis; A signal analyzer that filters the response and calculates results of measurements, commonly a connected or embedded PC in modern solutions; A form of output to the user (display, report, etc ...

7. Radio-frequency sweep - Wikipedia

   en.wikipedia.org/wiki/Radio-frequency_sweep

   A spectrum analyzer is a standard instrument used for RF sweep. It includes an electronically tunable receiver and a display. The display presents measured power (y axis) vs frequency (x axis). The power spectrum display is a two-dimensional display of measured power vs. frequency. The power may be either in linear units, or logarithmic units ...

   Screenshot of the spectrum of the refrain of a pop song (precisely "Più bella cosa" by Eros Ramazzotti): basses, drums and artist's voice can clearly be identified. Sonic visualiser melodic range spectrogram example. Sonic Visualiser represents acoustic features of the audio file either as a waveform or as a spectrogram. [4]
