Date: Sun, 29 Dec 2002 18:26:22 -0700 I usually read this group via gmane... We'll see if this comes thru! It appears that the recording as currently implemented reverses channels left for right and right for left when using analog LineIn. I have a JBR20 with 1.28 in ROM and have tried several daily builds of Rockbox up to 21dec (CVS had logged no changes since then). This can be detected and reproduced by anyone using just the JBR, factory supplied earphones (or a couple of other pair I tried) and Rockbox. Set up to record from LineIn. Plug headphones into LineIn jack. Set record level to max. (You should notice meter movement when speaking loudly, directly into earphone earpiece.) Start recording. Speak directly into each earpiece individually (eg "Left, left, left" into the left earpiece, then "Right, right, right" into right earpiece). Stop and save recording. Plug earphones into earphone jack. Listen to recording. If you record with the factory firmware, the recording of speaking into the left earpiece will play to your left ear, and right to right. Using Rockbox, the result is reversed. Playback firmware makes no difference. (I did find one pair of headphones that was wired in reverse. This caused the bug to appear as if it in the factory firmware. The defect is definitely in Rockbox and that one pair of phones, according to trusted test disks.) sdb Received on 2002-12-30 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
