I would like to see recorded signal’s spectrum in real time. I installed Voxengo SPAN Spectrum Analyzer plugin (http://www.voxengo.com/product/span) into Audacity, but it can be applied only for recorded sound, or I don’t know how to stream live signal to this plugin.
Can you help, please?
The closest built-in feature is the track “spectrogram view” (see: http://manual.audacityteam.org/man/spectrogram_view.html)
As Audacity does not have this feature, I’ve moved this post to the “adding features” part of the forum.
There’s free [Windows] software from UCL which does that … http://www.phon.ucl.ac.uk/resource/sfs/rtspect/
This request moved to http://wiki.audacityteam.org/wiki/Pending_Feature_Requests
And this thread moved to the Audio Processing section of the Forum.
