Voxengo SPAN is really a great analysis software. I can't work no more without it, it has a lot of features and it's really precise too. Last but not least, it's free too!!
If you need an FFT analyzer for your material, look no further than SPAN. It's got all the settings you really need and now that the peak hold hang issue is solved, it's perfect.
Thanks again Voxengo. I've recommended this plugin more times than I can count.
I love the fact that Aleksey doesn't assume which platform his users are making music on. Instead, he offers plugins for several platforms, including Vista x64, which is a big plus for me. Thanks, Voxengo!
