I made and tested this project on the MATRIX Voice Board.
Its project completely different from this [https://github.com/matrix-io/matrix-creator-android-things]
Because it is based on C ++ HAL realization founded this [https://github.com/matrix-io/matrix-creator-hal]
Advantages - much less hardware problems with the sampling frequency, and another advantage - it really works.
Another plus of this – normal app structure in single activity style.
About application structure:
All black magic casts on C++ level, Java does work as white collar --visualization and other network activity.
- Everloop control
- Mic Array
- Audio out**
** in progress
upd mic energy demo, mic with kissfft demo added & tested tested at 44100 sampling rate - ok.
Next step – audio out. Stay tuned!
