Reverb

How should I go about implementing reverb in NVDSP any ideas?

NVDSP currently only has filters. Reverbs come in many styles and flavours, so you'd first have to pick your algorithm that sounds good. I'll mention two ways to do it:

• IR (Impulse Response) can be used to apply a recorded room to a dry signal, resulting in the reverb of the room applied to the signal (I described this in your other ticket: Digital Room Correction #5)
• Delay with feedback, by playing delayed copies (with lower volumes) of the main signal you create a digital reverb effect. You could use the RingBuffer of Novocaine. Perhaps Novocaine has an example included that shows how to do a delay, you could tweak it to be a reverb. I know Novocaine has at least one audio effect in their example project.

The basic delay is already shown in Novocaine!
