Raph Levien	c934c830b6	Add timestamp stats gathering The android_glue unit now collects timestamp stats and reports them up through a ring buffer to the app. The app currently just displays a raw line in a text view, but we'll expand that out to smarter aggregation.	12 years ago
Raph Levien	766b572a64	Get audio parameters from platform On API 17+ (JellyBean MR1), get the buffer size and sample rate from the platform, and use that, rather than hardcoding the defaults. We're still using an internal buffer size (N) hardcoded to 64, so the amount of computation per callback is not as consistent as it would be if that were more flexible.	12 years ago
Raph Levien	9b3f8d4734	Add USB Host mode and pressure sensitivity. This patch wires up pressure sensitivity from the touchscreen. It also adds simple USB Host mode for MIDI keyboards (tested on M-Audio KeyRig 49 and Akai MPK mini). Finally, it cleans up a bit. The USB listening thread should be moved out of the activity and into a service (there can be problems on multiple plug and unplug). But this should be good enough to play with.	13 years ago

Raph Levien	c3509e50c1	Adding the glue logic (and an activity for testing) to run the C++ sound engine on Android. Note that this particular patchset disables the Java-based synthesis, so probably shouldn't be committed as-is to mainline.	13 years ago
