lame mp3's not completely gapless on 5G ipod

(1/9) > >>

Hi,

I bought an ipod 5G a few weeks back and decided to Rockbox it because the gaps between songs drive me nuts.  There was a big improvement with the gaps on my LAME 3.97b2 encoded mp3's but they are still not  compeltely gapless.  There is just a slight click or pop between tracks.  I tested some tracks encoded with ogg vorbis and those are completely gapless but I would like to stick with mp3.  Has anyone acheived perfectly gapless mp3's?  Could this just be an issue with the ipod port?

Thanks

I'm using a 5G iPod with all LAME encoded mp3's (using JR Media Center), and they appear to be perfectly gapless on my iPod using Rockbox -- i.e. I've never heard any pops between tracks, and I've listenned carefully for this on several albums with both very loud and very quiet song transitions.  Gapless playback on my iPod was the primary reason I stared using Rockbox, so I have been fairly critical when listenning for this.  As far as I know, at least SOME of these songs used LAME 3.97b2, but some of them were encoded with LAME 3.96.1.

Do you "always" get the pops between tracks, or is it just on certain songs?  What bitrate do you use?  My tracks are all either CBR160, or VBR "standard" (roughly 200kbps.)

I've only tested one album, The Wall, but it happens with every track.  The original files are stored as flac's and I used DBpoweramp to convert to vorbis at q7 and mp3 at V0. So the files have been in the 200 - 240kbps range.  I guess I could experiment with an earlier version of lame and maybe using the command line instead of dbpoweramp.  At least it sounds like I should be able to get it working on my 5G based on your experience.

Thanks,
Perry

"The Wall" is one of the albums I listenned to when checking for gapless playback (this seems to be the industry standard "gapless playback check" album) and I definitely don't have pops between songs.  I'm almost positive that this album was encoded with LAME version 3.97.b2 based on the date that I encoded it and the version of LAME that JR Media Center was using at that time (which was 3.97b2.)

My guess is that your issue has something to do with going to Flac first and then converting to mp3.  I encoded directly off the CD -- are you able to try this?  If encoding directly off the CD works for you, this would at least narrow down the issue.

Yeah, I'm not 100% sure LAME will create the proper gapless information off of FLACs.

But one thing to try is as he suggested, creating the MP3s directly from the CD. The other is that you try the FLACs to see if they're properly gapless for you.
