Based on my experience building corrscope, I feel this is the kind of project that will outgrow Python once you want to implement your own low-level algorithms, make it embeddable or shippable as an application, or parallelize it. I wonder what's the easiest way to port Python DSP code and UIs to a compiled/etc. language.
