My Google Foo may be failing me or it isn't a commonly asked question, but when opening the ReSpeaker with a low-latency API such as ALSA or JACK, what latencies can be achieved with it? E.g. can one open it with 48kHz and a buffer size of 512, going as low as 10ms that way? I am thinking about writing an interactive application, but would need low-latency for that.
