Audio spectrum analysis using high resolution oscilloscopes

Not many USB scopes works on Win & Mac & Linux too, so that proves me that guys from Pico really cares about us, customers. This made my decision much easier when I was looking to buy an USB scope.

Spectrum analyzers are particularly used in electronics laboratories associated with RF design and test.

Great job Keanan. I got DE-DP69666 the re-designed 8766 8mm from Sure Electronics. The connector is different and it requires a 67V power supply.

SPAN Plus is an excellent spectrum analyzer plug-in in more ways than one. Admittedly, you could get pretty much the same features in the free version of SPAN. But if the ability to compare the spectrums of two different audio sources at the same time is important to you, SPAN Plus is a no-brainer.

It is interesting to note that many users find the free SPAN to be just as capable as the SPAN Plus for their needs. But that is more a testament to the excellence of the free plug-in than it is a criticism of SPAN Plus.

SPAN Plus especially impresses users with its ability to perform multi-track comparisons from a single window. The ability to compare EQ curves pre- and post-mastering on the same graph makes it a flexible and useful tool for mixing and mastering.

To put these figures in context a typical tape deck would have 95 to 55 dB of dynamic range, a quality power amplifier 75 to 85 dB and a top end CD player 85 to 95 dB. As you will see below not all CD players live up to this.

While this is how a sophomore electrical engineering student would probably build it, modern analog designers would use a switched-capacitor bandpass filter, which provides high Q, low component count, and reconfigurability. If I were to do it, I 8767 d get a single LTC6559 (or something of that sort) and switch it rapidly between each of the 65 bands you want to sample. The output would be precision-rectified and then sent to a 6-to-65 analog mux, which would drive 65 different electrolytic capacitors. By switching the frequency and the mux at the same time, each electrolytic capacitor would store a voltage representing the energy in that particular band. A 95-cent MCU (or much more expensive analog timer circuit) would be used to drive the switching action.

The oscilloscope displays the amplitude of waveforms on the vertical axis against time on the horizontal axis - signals are displayed in the time domain.

A spectrum analyzer measures the magnitude of an input signal versus frequency within the full frequency range of the instrument. The primary use is to measure the power of the spectrum of known and unknown signals. The input signal that most common spectrum analyzers measure is electrical however, spectral compositions of other signals, such as acoustic pressure waves and optical light waves, can be considered through the use of an appropriate transducer. Spectrum analyzers for other types of signals also exist, such as optical spectrum analyzers which use direct optical techniques such as a monochromator to make measurements.

SPAN provides you with a very flexible “mode” system which you can use to setup your spectrum analyzer preferences. You may specify Fourier block size in samples, FFT window overlap percentage, spectrum's visual slope. Beside that you can choose to display secondary spectrum of a desired type (. real-time maximum, all-time maximum). Spectrum can be smoothed out visually for an easier examination.

Secondly I got Arduino compile errors. Suggestions?

MMultiAnalyzer also comes with features that make it easy to identify specific frequencies. These include normalization, super-resolution, and de-harmonization features, all of which help you pinpoint problem areas in your audio.

What do you mean. Could you elaborate?

Realtime spectrum analyzers are able to produce much more information for users to examine the frequency spectrum in more detail. A normal swept spectrum analyzer would produce max peak, min peak displays for example but a realtime spectrum analyzer is able to plot all calculated FFT's over a given period of time with the added colour-coding which represents how often a signal appears. For example, this image shows the difference between how a spectrum is displayed in a normal swept spectrum view and using a "Persistence" view on a realtime spectrum analyzer.

The individual plug-ins in the Audio Analysis Pack come with an impressive wealth of features that provide tremendous value. Most users seem sufficiently impressed with the amount of information provided, with the automation and MIDI capabilities simply being the icing on the cake. For many, the clever implementation of CC/automation generation features makes these tools so much more versatile than most standard spectrum analyzer plug-ins.
