Hi chris, I borrowed an ipod shuffle 3gen (what apple calls "iPod shuffle 2nd generation Early 2008") from a collegue but that one seems to be up to date too. All the volume adjustment fields are "00 00 00"
Does the "revision" as shown by udev represent the firmware version? > ID_VENDOR=Apple > ID_MODEL=iPod > ID_REVISION=2.70 If iTunes shows the firmware version somewhere in device information you could compare it to the output of udevinfo --path /sys/block/sda --query env or /sbin/udevadm info --path /sys/block/sda --query env > I'm still playing around with ReplayGain and SoundCheck > In particular I'm trying to see if there is a 1:1 ratio between RG and > SC or not. > I found they iTunes-SC values clearly unsatisfying so I'm trying SC > calculated from RG now but I'm not done yet :) Well, you know that Richard and I implemented replaygain to sc conversion in april/early may, don't you? The current CVS version of gnupod will take in this order RVA2/XRVA tags, or "replay_album/track_gain" from APE tags or id3 TXXX tags or iTunes soundcheck values (as found in iTuneNORM comment tags) plus RVAD tags (iTunes way of encoding the -100%..+100% volume slider) Check out the the mailing list's archive http://www.mail-archive.com/[email protected]/index.html#00222 Implementing the conversion from soundcheck or any other volume adjustment value to something the ipod understands is very easy. I'd do it a 5 minutes if we find out how to distinguish between old ipod shuffles that interpreted the volume field as "100 minus volume adjustment in percent" and those who interpret it as "signed integer for volume adjustmend in dB". Currently gnupod writes a value of 100 into that field. Now according to the new semantics of that field this would mean a gain of +100dB. Obviously the "new" iPod shuffle ignores those values or your ear drums would simply go "pop". Now what we don't know is how and "old" iPod who expects that 0..200 value will react to the values outside that range. Something like "00 00 03" would probably be interpreted as "-97%" instead of "+3dB" but how will it interpret a value of "FF FF FB"? Your guess is as good as mine. > Finding itunes 7.4 was really easy > but where might I well find an old firmware for a 2nd generation shuffle? > Anyone have an idea? Google? Just look for "ipod" and "firmware" and the first hit was this: http://www.felixbruns.de/iPod/firmware/ Or just google for "ipod firmware downgrade" and I am pretty sure you'll find what you need. cheers -henrik _______________________________________________ Bug-gnupod mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/bug-gnupod
