 ## Caveats
 
+- `AudioBuffer#getChannelData` is implemented but not reliable in some situations. Your should prefer `AudioBuffer#copyToChannel` and `AudioBuffer#copyFromChannel` when you want to access or manipulate the underlying samples in a safe way.
 - `Streams`: only a minimal audio input stream and the `MediaStreamSourceNode` are provided. All other `MediaStream` features are left on the side for now as they principally concern a different API specification, which is not a trivial problem.
