Voxengo SPAN Plus

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

As a Mixing and Mastering engineer, and also as a University professor, I have been testing different spectral analysis plugins for years.  Without a doubt, Voxengo Span Plus has all the features that an audio engineer requires when performing a detailed analysis of any type of signal.  Its design is very intuitive, and totally versatile.

As usual, Voxengo has been carefully behind every detail in the design of Span Plus.

I think Span Plus is my best partner when it comes to mixing or mastering!

It is very hard to find something bad to say about your plugs.  You have helped me make giant leaps in terms of mastering.  As you know, I own most of your plugins and will continue to do so.
