Audio Weaver is a graphical tool for doing audio dsp. You use a drag-and-drop interface to configure your signal flow graph. When you "run" the system your graph is used to dynamically instantiate the necessary low level functions and compose them together. While the design is running you can do live tuning (changing gains, filter coefficients, delays, etc.). The low level functions have implementations on several architectures (PC, ARM Cortex-A and M, Tensilica HiFi 2 and 3, ADI SHARC, TI C66xx, plus a few more). This means that your signal flow graph is cross platform.
