[linux-audio-user] Stereo effect question

Another noob audio effect question: What tools (software) and techniques are used to accomplish the effect of a source of sound appearing to move gradually from one speaker to another? I'm not talking about mere channel swapping, but rather something like the final auditory illusion suggesting gradual movement, e.g. a horse galloping by, or a train with its whistle being 'dopplerized'. Is this probably way over my head? Or something easily accomplished once I get a nudge in the right direction? My soundcard (SB PCI 16) is actually quite limited, but I should think that, given the right software and data input, the computer should calculate how to simulate the effect, even if my consumer-grade sound card could only render the effect with limited fidelity. (An analogy might be a great quality video clip on a crappy monitor?) I'm not that concerned with real-time performance--couldn't care less if it takes 5 minutes to process a 5-second effect, as long as I know where in the workflow to try to add the new task. ;-) Thanks again for any thoughts on the matter, Mark ===== -- Seek professional help!
