I think VLC also does recording, but I'm certainly in no position to comment on it. I'm not familiar with their codebase and I don't want to lie :). I don't know what PulseAudio considers "very low latency" and there aren't any numbers on that page to indicate it, but in my experience, PA's best latency possibilities are about an order of magnitude away from being useful for any kind of hardcore real-time processing. This isn't a problem as far as PA is concerned since it's not what it was conceived for, but it won't cut it for applications which need that kind of capability. PA also doesn't really provide latency guarantees, either. In fact, it's mentioned on that page: > So in summary: tell PA what latency you want, but program defensively so that you can deal with getting both lower or higher measured latencies. I don't know if that has improved though. The last time I had to poke PulseAudio was a few months before that page's "Last Edited" timestamp. Edit: For what it's worth: I never managed to get PA to consistently keep latency below 25-30 ms, which is at least 10-15 ms away from being adequate for real-time audio processing. I guess it is a cornercase though, and probably outside the Gnome project's interests. Reading the other comments in this thread, I assume VLC's problems with PA aren't related to latency.
