Spectrum Analyzers

Spectrum Analyzers?

What would you recomend.

I know there is the Analyzer pack from wolf, also there is a free one, any other recomendations?

Here's my list of NON-SCOPE windows based analyzers from a few years ago:
--------- Free Windows Spectrum analyzers & metering tools ---------

• Standalone:
  
  AudioAnalyser is a realtime frequency analyser for audio signals. You can combine the "AudioAnalyser" with "Multisine", if your soundcard supports the full duplex mode (only very old soundcards don't). With this combination you have a full equipped audio suite for your measurements.The application is written in C++ and uses the VCL library an

  Smartelectronix Fre(a)koscope:

  Fre(a)koscope is an FFT-based real-time spectrum analyzer featuring: lin/log/semitones/third-octave/Bark scales
  - window size selection
  - frequency zooming
  - freeze
  - peak hold
  - cursor information (amplitude+frequency)
  
  Blue Cat's FreqAnalyst is a spectrum analyzer that has been designed to provide extreme smoothness and high resolution for both time and frequency: unlike most spectrum analyzers, Blue Cat's FreqAnalyst is able to display continuous variations even with a very high frequency resolution, thanks to its unique smooth interpolation algorithms. A special thresholding system has been developed to help you see the important parts of the spectrum easily. In case you need extra precision in a particular frequency range, you can zoom the display and check the part of the graph you are interested in.

  DetectComp is a donationware Windows VST that features Realtime analysis, Velocity Distribution, Frequency Distribution, Velocity and frequency evolution

  Sonalksis FreeG is an intuitive tool that can be used for a variety of applications to increase the control and flexibility of the signal flow in the insert chain of the host. To make the workflow and the overview of the signal processing easier, FreeG provides extended, customizable metering features and settings.

  Gonio2/3 is an Audio Vector Oscilloscope (Goniometer). It can give you a detailed picture of the relationships of a stereo signal. This is often used to watch for mono compatibility of a recording. Unlike a "normal" oscilloscope the image is rotated by 45? so if you have an identical signal on both channels you'll see a vertical line.

  +phasescope implements the standard studio tool for seeing the phase relation between your left and right channels. also includes a bit meter.

  Sonic Visualiser is a spectrum analyzer whose goals are
  - To provide the best available core waveform and spectrogram audio visualisations for use with substantial files of music audio data.
  - To facilitate ready comparisons between different kinds of data, for example by making it easy to overlay one set of data on another, or display the same data in more than one way at the same time.
  - To be straightforward. The user interface should be simpler to learn and to explain than the internal data structures. In this respect, Sonic Visualiser aims to resemble a consumer audio application.
  - To be responsive, slick, and enjoyable. Even if you have to wait for your results to be calculated, you should be able to do something else with the audio data while you wait. Sonic Visualiser is pervasively multithreaded, loves multiprocessor and multicore systems, and can make good use of fast processors with plenty of memory.
  - To handle large data sets. The work Sonic Visualiser does is intrinsically processor-hungry and (often) memory-hungry, but the aim is to allow you to work with long audio files on machines with modest CPU and memory where reasonable. (Disk space is another matter. Sonic Visualiser eats that.)

I use Visual Analyser a fair bit.
http://www.sillanumsoft.org/
Its free and very comprehensive, but of course not integrated into SCOPE.
I tend to use it for testing, not for mixing and mastering.
For mixing and mastering I use Nugen Visualizer. Again not intergated into SCOPE but I sometimes feed a stereo pair back into Cubase/Samplitude to check the spectrum of particular SCOPE tracks.
Maybe not the answer you are looking for but I find these solutions better than the available spectrum analysers available for SCOPE.
I have not used the SCOPE Measurement pack. Now that looks pretty good!
I have not seen anyone here talk about that system??

Usually Valis doesn't miss a lick......

My scope pc is too 'old' for Scope-based analyzers, so I didn't include in my list since I can't properly test them. But you had another thread here recently where you listed a number of other useful Scope meters as well no?

[Liquid EDGE]

Thanks for such a detailed list valis. Will look into them, i was mainly talking about ones for scope though, but doesn't look like there is much else other than what wolf has developed (which looks pretty decent), was just interested to see if there was other options.

Cheers for the link xite-1/4live.

Nice one guys.

[Liquid EDGE]

Just noticed this..

http://www.sonic-core.net/en/products/measurement.html

But it's not in the S C online shop.. How does one get hold of it?

Am i being thick?

[Cochise]

Not for Scope (I often run close to DSP limit, so not enough power for that) but Spectrogram is often a usefull tool to me when it comes to analyze not instantaneous events only.

I use Sillanumsoft Visual Analyzer me too, for frequencies and waveform analysis, and even for measurements, coupled with an USB AD interface and some calibration circuit.

it's an industrial grade product that you normally request directly from the manufacturer.
There are high precision signal generators and such stuff mentioned in context with it.
Holger and Juergen had such a business after they left Creamware's developement team due to CWA's financial problems.

Very nice one

That really does look lovely sonicstrav.

Was hoping to find a pretty one for the Scope, as well, it makes sense to have the analyzer sitting at the end of the chain..

Suppose i could create an extra input into cubase with the master out in scope ruted to tthat and a native analyzer sitting on that in cubase if i was to use a native one.

But again, considering now having an xite-1, it makes even more sense to have one in the scope enviroment as analyzers can use quite a bit of processing.

Thanks so far for all the input. Just need to way up UGI, FUNCTIONALITY and PROCESING POWER
