How can I do this with high accuracy. You know, I can not depend on my ear. And I just have a Nexus S, and no hardware access. Is it possible to get following data with high accuracy by API/ software? 1. cold output latency 2. warm output latency 3. continuous output latency 4. cold input latency 5. continuous input latency
