Spectrum analyser apps
Mainly out of curiousity I'm interested in recommendations for cheap/free spectrum analyser programs/apps I can use on my Microsoft Surface.
I have a tuning app that does a bit of this and it's sort of interesting to see what happens to the different frequency distributions at different times - e.g. an attack produces noise across the full distribution, forte increases volume around the frequency you're playing more than it increases volume at the note itself, pizzicato has virtually no overtones, playing on lower strings produces more irregular lower resonances than playing the same pitch on higher strings.
So interested to look at this in more detail. If you have any recommendations then let me know!
I use "Advanced Spectrum" on my Android phone.
I don't have a good answer at the moment, not having done this for some many years, but I recommend you look for one with a good 3d spectrum display. What this provides is a stack of snapshots through time leading off into the distance, like looking at mountain ranges from above. This allows you to see the trends of a violin's performance through a series of notes. When you see that, you realize that though you change the notes, the violin still amplifies the sound differently according to frequency, and you can see the zones of amplification and subduing really easily.
There are a few I can think of. I don't have a Microsoft Edge so I don't know if the OS is a light version of Win10.
If you have a Linux-based system there is "Open GL Spectrum Analyzer", a free 3-D visualization in colour that does what Michael describes. Quite restful to look at as the music is playing, I find.
thanks all for the recommendations!
