Some history...

Before we ran into the Antress plugin problem with buffer size limitations, (see below) we just had a plain old effect loop...get the input samples, pass them to the effect, save the output samples.

But, the hack I put in to limit the buffer size to only 8k (normally 512k or so) severely impacted performance. So, Michael C. added some intermediate buffering that sped things up quite a bit and this is how things have worked for quite a while. It still didn't get the performance back to the pre-hack stage, but it was a definite benefit.

History over...

I've recently (May 2014) tried newer versions of the Antress effects and they no longer seem to have a problem with buffer size. So, I've made a bit of a compromise...I've made the buffer size user configurable. Should have done this from the beginning. I've left the default 8k, just in case, but now the user can set the buffering based on their specific setup and needs.

And at the same time I added buffer delay compensation, which allows Audacity to account for latency introduced by some effects. This is based on information provided by the effect, so it will not work with all effects since they don't all provide the information (kn0ck0ut is one).
