I've been doing some top level planning regarding the gstreamer crossover /dsp setup. See below.

http://www.lucidchart.com/publicSegm...3-53d40a7c6148

The crossover editor will be a node based system, similar to what you find in modern 3d rendering/compositor apps. See Soft Image ICE, Blender etc. The node tree data structure and params will be sent to the DSP for processing. It editor could quite easily be web app so you can update your crossovers in your arm chair with and iPad 3 adjusting tweeter delays and phase on the fly.

I burning the midnight oil doing some sine wave sweeps on my DSP 31-band EQ. I'm not using the traditional biquad DF1/DF2T filters but a modified couple form that gives a flat quantization error. :-)

I love the DSP user interface on the KX-Project. It's extremely intuitive and they make it easy for others to create plug-ins (DSP processing blocks) that you may connect together to realize routing and processing. I think ease of use is the primary goal here as well as the freedom to design custom processing blocks.
Web interface sounds like a really good idea. Or even just having the Editor run on a remote computer.

EDIT: I wrote this without any knowledge of GStreamer. I'm reading about it now.
