Spectrum Analyzer for Multiple files

[jim1961]

Are their any freeware programs that will let me look at two audio files spectral plot at the same time?  That is, one plot on top of another.  Will be working in 16/44, 24/88, 24/96 and 24/192 .wav formats.

 

My Izotope RX2 program (see example) lets me look at one file nicely, but I want to compare masterings/versions.

Compare how exactly?

Their spectral plot.  I.E. different masterings of the same album/song can have very different EQ.  I want to be able to see that difference.

You can load multiple files simultaneously to Audacity and view spectrograms simultaneously.

I have Audacity.  Haven't figured out how.

Open some project, then import files to that project. And then from the channel drop-down menu select Spectrogram view. You can adjust spectrogram settings through the settings-dialog. There is also "fit to view" option to fit all channels neatly in space available in the window.

I dont want spectrograms, I need line plots.  Did you miss the pic example in my first post?

 

Still cant get it to work.  Never liked Audacity much.  Now I remember why.

Line plots are not very useful for something as varying and long as a song. Spectrograms are much more useful...

So Audacity cant do what I want.  Confirmed.

You can google that or hit youtube.

You asked for spectral analysis...

...as a line plot (shown with a pic).  Does the pic look like a spectrogram to anyone?

[jim1961]

So, were back where we started.  Anyone else?

Isn't below a line plot? Done in Audacity.  If you want to compare two plots, you can export both to text files and use any charting software, including a spreadsheet, to compare them.

Yes, I can get one plot to show, sure.  I want two or more to show.   I want a program that can do it in house without exporting to still another program.

Good luck. Let us know what you find.

I haven't found anything, thats why I am here

[pkane2001]

Well, if you don't find anything else, try the Audacity/spreadsheet method. Should only take an extra few seconds to do it this way.

I use Octave for all my plotting needs.
