Report input/output latency #42
Description
Problem Statement
In order to give users the ability to do full latency compensation, it is crucial that we give them the reported input/output latencies, if provided by the driver.
This is especially important with #22 that will bring its own latency when resampling.
Proposed Solution
Add a latency: Option<Timestamp> to AudioInput and AudioOutput exposing the reported latency information
Alternative Solutions
- Not reporting latency: having the information could be misleading as an accurate measurement, which I don't think it is on most platforms unless using pro audio with correct latency measurements.
- Reporting latency another way (how?)
