It has been two months since the last blog entry and a lot of stuff has happened. We began to rewrite the audio module to get rid of all external libraries. The idea is that the OpenMAX interface (of the Raspberry) has everything we need to decode the audio directly. However, there are still minor problems with the code which prevent the release of a new prototype.
This was the first issue. The second issue is that we are very busy with the module for the personalized recording. Our current approach, the use of a artificial neural network, is very promising but due to the lack of proper meta data and the fact that the existing data is very sparse, it is challenging to create good predictions. Since the recommender part is the heart of our system, we are focusing on this issue right now.
