I don't have time to dig up the code at this hour, but I developed something that sounds like what you described earlier for a client several years back. I think what you want is an Offline Host for an AudioUnit Graph. Such a setup can run faster than real time, taking your buffer of samples, processing it through the low-pass filter, and then saving to a new file. Rather than save to a new file, you could probably just store the data in a new buffer. The key is that this kind of code certainly doesn't require 10.10 The only complication is that if you want to send audio to the generic output, then you're locked into real time. That makes it a little more restrictive than offline rendering, where you can process something like a low pass filter much, much faster.
