[comp.sys.next] Questions: Realtime on the DSP

christir@ifi.uio.no (Christian G. Rosenvinge) (06/21/91)

	I am trying to do some signal processing with sound input on the DSP
	and I have some questions:

 1.	Is it possible at all to stream samples from the DSP port (on the
	back of the computer), do continuosly filtering (fast convolution)
	on the input data, and streaming the data out to loudspeakers?  I 
	would like to use 22.05 kHz sampling or best 44.1 kHz.  I should not 
	lose samples, and the output sound should not be 'stacato'.  
	I know you can't record and play at the same time with the DSP, but
	perhaps it is possible to stream samples into memory somewhere, while
	the DSP is occupied with processing? Is it also possible to stream 
	from memory to the loudspeakers port while the DSP is occupied? 

 2.	If this is possible somehow, how do I acess the DSP input port on
	the back of the machine?

	If someone have done, or are working with something similiar please
	contact me.
