I have a question about a possible new iTunesEncode feature (or any other program driving Apple's AAC encoder). Wouldn't it be possible to add a gapless feature? It might sound silly, but after all, nyaochi did it with the latest Fraunhofer MP3 encoder (here and here). I'm not a coding expert -I'm not a coder at all- but I think that doing it wouldn't be an impossible task.
Adding somewhere in the tags the precise offset (constant for Apple's encoder) and calculating the amount of padded sample maybe suffice? I don't really know. faac and Nero AAC are gapless, and apparently Apple is not hurry to implement this feature. It's a pity, because Apple's encoder is pretty good. Gapless playback is not possible on any iPod, but on a computer (playing with foobar2000 as exemple) users would benefits from it. Could we reproduce Nyaochi's ACMenc patch to work with iTunes? Or make something similar? What do you think? |

QUOTE (bond @ Jun 25 2005, 05:09 AM) ok so its seems to be indeed a non-mp4 file, thx!  I think I see what's going on here. It seems that Audible are using a variety of formats. The file I have is directly from Audible.com and uses a proprietary speech-based codec. However, the Audible files from the iTunes Music Store apparently are AAC and have the same bookmark & chapter-stop features. Check this out: QUOTE 2. Audible File Formats
A. Enhanced playback features Audible utilizes a proprietary file format that includes custom features that improve the user experience over regular MP3 formats when listening to spoken word audio. Audible files provide the ability to bookmark and remember your last heard position on each and every file stored on the iPod. You can switch between Audible files, exit and listen to music, and go back and forth and the iPod will remember your last position played and pick up where you left off. Also, Audible files are broken up into different sections, either by timed intervals, chapters, or program segments. These segment markers allow you to quickly advance backward or forward to the next section. . . . Audible files purchased from the iTunes music store are encoded in Apple's AAC format, and provide the same enhanced playback improvements as files with .aa extension downloaded directly from Audible.com.
