Voxengo SPAN Plus
I try to avoid and have working at the same times, 2 Reason senses (Audition and Vision).
But when my Audition is a bit lost, Vision comes in and SPAN Plus is always laying at the back of my session.
It helps me to work faster and get back on tracks quicker.
When my students ask me a good Analyzer I say : SPAN.
I have many FFT and spectrum display programs (at least 12 on this machine).
I was, once again, looking to generate some noise profile images for a report and in frustration, went back to the web looking for alternatives - I found Span Plus.
Several of the features make generating the presentation materials I need super easy and effective - taking the files into an editor/mixer so that I can use the plugin is completely offset be the ease of seeing what I need and capturing PNG files all within the software - I know it probably wasn't your intent to support the test and measurement industry, but it does!
Impressed enough that I just bought the Premium Membership and am looking forward to using the tools for their real intent - Music
