I have read a lot of different post, and I can't made up my mind, because the situation seems to be quickly moving.

1. what is the way to follow to obtain gapless AAC ? With witch countainer ?

2. Can I obtain gapless MPC with EAC + iTunes ? (method of the script)

3. When I have my gapless AACs, which hardware player can play them "gaplessly" ? which software player can play them "gaplessly" ?

4. There are some portable players which play AAC. Are there DVD player wich can play AAC like yet MP3 ?

5. And what about replaygain ?

6. Why cannot we have a command line encoder as mpc or mp3 or ogg ?

Thanks for a newbee

edit : 2 question more

Nero AAC with MP4.



iTunes has no gapless support AFAIK.



foobar2000 is the only one I know. Maybe winamp with FAAD too?



Current DVD players don't. However given that one of the biggest manufacturers of decoder chips announced that it's future line will have AAC support, it's pretty safe to say they will appear in the near future.



foobar2000. Maybe winamp with FAAD decoder but I don't use that.



?!

Both NEncode and FAAC will do AAC encoding from commandline.

ok thanks.

If i understand correctly, only Nero AAC is a gapless codec.
I've heard about codec incompatibilities ; Nerao AAC could be played on every player, with tags and gapless capabilities ?

Also FAAC is gapless, free, but has a bit lower quality than Nero (at least at 128kb/s).

There were problems with Nero AAC with the iPod, but that was the fault of Apple, I think there is already a firmware update avaible that solves these problems. But you won´t have gapless playback because the player has to support that function.

strange that AAC as so much problem of compatibilities between codecs, players or countainer...

What a pity, MPC was so good, and now it's (almost) dead ; it had perfect tag capabilities, perfect replaygain capabilities, was gapless, and so on...

and that manufacturer is???

I'm also dissapointed that mp4 and m4a support is growing so quickly and the only hardware aac player worth it is my phillips expanium 503. Even phillips dropped aac support after this model, so if there's no aac support, i see even more difficult gapless playback.

Are there any portables supporting gapless playback for any format (besides cd)?

Sigma Designs. The same jerks that tried to steal XviD's code some years ago.

The Rio Karma plays back lame-encoded MP3 and Vorbis gaplessly.

Does it really support the LAME tag (needed for gapless MP3) fully?!

The basic stuff works everywhere. Mostly "extras" like some Apple tags (album covers) and gapless support is not generally present, but this is true for e.g. mp3 as well.

That's what has been reported in a thread here.

If i've heard correctly, AAC is the audio part of MPEG 4 project.

MPEG4 is video there is in DVD now no ?

so why DVD players can't play AAC ?

But maybe I've misunderstood...

current DVD players use AC3 audio and MPEG2 video

some new DVD players can play a subset of MPEG4 video, but most dont support MPEG4 audio yet

If I understand well, MPEG 4 is the next VIDEO codec of DVDs ?
So maybe AUDIO MPEG4 (AAC no ?) will be readable in any DVD player next years...




I think that gapless support is not an extra capabilitie...
Some album need gapless playback !
If you cannot use a unique codec for all your audio collection, it becomes a pain to encode : you must think what kind of music is this ? Need I gapless support ? Need I hardware support ?

I would to find the better codec (for my usage), and I don't want to change of codec depending of the CD I plan to encode.

You will need to check what hardware you have first and foremost then. It's not because the format (can) support gapless that the total of the ripping/encoding/playback hardware can guarantee gapless support.

Is Ahead planning on bundling a “supported” command line encoder with Nero? Maybe with encoding quality switches and tagging support? Not that nencode.exe and tg.exe aren’t enough, but it would be a “nice to have”.

If you are stuck on AAC but need gap-less support you could always encode one file per album.
