Is there anything else in the iRiver that limits the full capabilities of the UDA1380TT ? As libmad decodes MPEG audio to 24-bit accuracy, it would be nice to be able to use that feature. Any thoughts? The obvious drawback is the 50% increased memory usage for the PCM buffer, but it does remove the need for Rockbox to dither the 24-bit output of libmad to 16-bits. Also, I'm sure this is an FAQ, but I haven't found the answer - is it technically possible to record from the FM radio on the iRiver H140? I understand the iRiver firmware doesn't allow it. Thanks, Dave. _______________________________________________ http://cool.haxx.se/mailman/listinfo/rockbox Received on 2004-12-31 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
