ObjectProDSP

ObjectProDSP is a tool for DSP design and analysis.

• Define and edit a DSP network graphically.
• Execute the network interactively with plots and listings at any point in the net. Tweak parameters, add or replace nodes and threads and execute again.
• Learn DSP by playing with DSP operations and seeing the results instantly. ObjectProDSP is a powerful tutorial aid.
• Use feedback loops and multiple sample rates in the same network.

ObjectProDSP has not been updated for some time. It will not compile with current compilers. However the binary image was linked statically and runs on current versions of Linux. You may need to relink the kernel to support the older "a.out" executable file format. Some operating systems, such as Redhat 9.0, have "a.out" support as a module. This is not automatically loaded when you attempt to execute an "a.out" binary. You must install it with following command as root:
modprobe binfmt_aout
You either have to do this every time you reboot or you can put it in a local init file such as /etc/rc.d/rc.local.

Fedora 3 no longer has module support for "a.out" executables in the standard kernel. ObjectProDSP crashes when this kernel (2.6.9) is relinked with "a.out" support. However the problem goes away with the (2.6.10) kernel.
