I agree that handling the correction files would be great. Unfortunately, in this case the problem is resources. Handling the correction files takes about an additional 40% CPU cycles on the PC, and that doesn't take into account the extra disk reading. In WavPack's "high" mode that would put us at 100% boost ratio (without any dsp functions on), and even the default mode would be pretty boosty. It would be pretty easy to go ahead and try this for the fun of it, but like Thom says, the whole codec structure has the Rockbox OS doing the disk access, so there's no way to easily do it. And I just thought of another headache! When WavPack on Rockbox currently does a seek, it just estimates the position in the file where it wants to go and just starts playing there (even if it's not exactly the right timecode). When you're handling correction files, you have to seek both files (obviously) and you would have to make sure you really had the exact same timecode (and probably hunt around for it). On the PC this is instant; on Rockbox it might be painful. Received on 2006-02-12 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
