Quite a tricky task. I was just thinking the other day that this sort of method could be used to piece together voice response and other audio, put together in memory, thus allowing rockbox to talk. So is the issue that we have to frame align any inserted data, or can the MAS chip be turned off/reset externally and a new frame started? I think I need to re-read the MP3 and MAS specs. I'd like to help. Regards, Greg Received on 2002-10-18 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
