Ivan you bad boy.

is there o way to encode some tags inside te mp4 file.
just liek with nero.

tracn number & total track number
Artist
Album
title

would be perfect

I think Nero is right in not exposing too many features. They have a name to hold up high and on the long run too many switches with unknown and probably negative effects can only hurt them. I thinks such things belong in a beta-test.

Furthermore, I, as a user, do not want to be thinking about lowpass, PNS and whatever kind of switches there are. I do not even want to know what they are and I expect the encoder to make such decisions by itself. This is after all a consumer product, not an experimental encoder. If with the help of switches better quality can be achieved than the encoders defaults in a large amount of cases, the defaults are poorly chosen and Nero devs are not doing their job right.

The only things I, as a user, do want to have a saying in are filesize (bitrate) and compatibility because these things directly affect the usability of the product for me.

I just tried out this on a Windows machine. Very pleased with what I have heard so far.

Man I wish there was better audio support on OS X for all of this cool stuff. Only negative about being on a Mac.

This topic got so long so fast that it's pretty much unusable.
I hope somebody creates a Wiki of what's important to users.
Anyway, congrats to Ivan, Garf, Menno and the rest of the Nero people involved.
My one request is better ability to control size of HE-AAC output; q 0.225 seemed fairly close to 48kbps nominal, but averages have been at 54 kbps in some of my trials.
For musicphones storage room will be a constraint for a couple more years, so the HE-AAC size should be more closely constrained than LC-AAC.

Every AAC compliant device can play the files, however, a pure LC AAC decoder will decode a HE AAC file, but only the LC AAC part of the file. So you will get degraded quality, compared to decoding with a HE AAC decoder. For devices/decoders like that it is better to create LC AAC files instead of wasting bits (and decreasing bandwidth a lot) by using HE AAC.
Same sort of story applies for HE AACv2.

Can it be configured with EAC to create .m4a files directly when extracting tracks fom audio cd?

Could Ivan or Garf please tell us how to embed album art into the encodes?

Currently with Foobar - but command line tagging will come very soon.

I just checked the site and you guys at Nero have updated it with a PDF manual, which is quite welcome.

Would it be possible, though, to provide a Linux i386 binary? If necessary, you could, perhaps, create the encoder as staticly linked, to avoid having problems with libraries shipped with the diversity of distributions.

Thanks, Rogério Brito.

Yes, just stipulate the extension as M4A instead of MP4. Same with foobar.

Ivan, thanks for all your teams work and giving this out for free.

My only suggestion is that if possible, support ALAC with the same enc/dec -- while we know it's an Apple format, it would be pretty kickass you have to admit. Hopefully licencing doesnt get in the way of that potential road.

Sorry if this has alrready be answered.
I just quickly passed by the 16 pages but didn't find an answer.

i can't playback the mp4 files in winamp.

first i tried with my original 5.12 with some mp3 plugin form audiocoding

i deleted it and reinstaledl a fresh copy of winamp v5.21 lite
got i new mp3 plugin from rareware.org (still from audiocoding but maybe newer)

but i still get the same errors:

"maximum numbers og scalefactor bands exceeded"
"Gain control not yet implanted"
"Pulse coding not allowed in sjort blocks"
"Scalefactor out of range"
"quantised valie out of range"

i used the folloowing command line in CDex

-br %3 -2pass -if %1 -of %2

%1 = input filename
%2 = output filename
%3 = bit rate in bits/sec

and i have not modified the file in anyway since the extraction


-- Edit --
has sombody teste if these .mp4 files work on a ipod?

I got some from the psytel encoder, that my ipods just skips by whenever it tries to play them.
Playback is fine in winamp though.

UPDATE

i triede getting the full winamp 5.21 with nullsoft's own mp4 pugin.
Didn't help
Still no playback, but now there is no error msg.

-- edit --

Found te bug. is has nothing to due with the encoder.
If i extract the .wav and run the commandline myself, the files playbacks perfectly.

The only thing that I'm thinking it might be is the %3, seeing how the nero encoder passes the -br parameter as bits per second, so 128 kbps would be -br 128000 . You could be getting encodes that are at .128 kbps (128 bits per second), and winamp is puking. Do the files play in foobar2000 or any other player?

My nero aac standalone encoded files play fine in winamp.

Oh, and getting a new mp3 plugin from rarewares shouldn't matter at all; this is aac / mp4 / m4a, not mp3.

ALAC

• is completely proprietary
• is completely non-standard
• is non-free
• is very badly supported in general
• has inferior performance and features compared to other formats which ARE completely free, non-proprietary and well-supported

Each one of those would be enough to switch to something else. There is exactly ZERO chance that we will ever support it in any way (not that we even could, because as I already stated, it's proprietary). Please, take a look at FLAC or Wavpack and leave alone the horrible abomination that is ALAC.

What version of CDex did you use?

I tried 1.60 from rarewares with different bitrates but couldn't get Winamp to barf.

If that is of any help, our PNS and IS powered modes at 64 and 80 kbps are done, and they have been sent to tuning process

So expect maximum squeeze of LC-AAC for those bit-rates in the next couple of weeks

Off-topic posts split here. No more of that, please.

if this off topic let me know.


but i remember distinctly the lowpass in 16kbps hev2 being just under 15khz, what happened to this to make it a pitiful 10khz? they both sound pretty good for the bitrate, but i much prefer the higher frequency of the older nero.

Great news! Thanks for the superb work! Can't wait for it.

Awesome, thanks! This is really appreciated

one question, maybe allready asked, why is it that it does nothing and then it suddenly finishes? would be better to see a sinning simbol, or something. or at least one:

"Working, please wait ..."

Any help with the album art? I want to encode all my FLAC files for my shiney new iPod!

Our very own "optimus" (Stanley Huang in Shanghai), whose home in HydrogenAudio has been http://www.hydrogenaudio.org/forums/index....topic=36870&hl= , has released a new version of his Media Coder, 0.3.9, with built-in support for this Nero encoder. View the changelog and click for a Sourceforge download mirror from http://mediacoder.sourceforge.net/changelogfullpack.htm .
I think Stanley deserves his own MediaCoder home here in HA.
Ver 0.3.9 works beautifully for me; output is *.m4a. The program places just the neroEncAac.exe file in its default codecs folder, but you can copy over from the Nero download the neroEncAac_sse2.exe and point to that file in "File>Settings" -- if that works with your CPU.
Thanks, Stanley!

I already added a nice progress display a few days ago

Many thanks, but where this version is available?

Available on the next update.

my version is 1.51 but my bug was caused by the ID3 tag that CDex adds to the file.
Disable the id3 tag and the files should playback perfectly.

Super high level question:

Is there a set of test results to compare this encoder against LAME, in particular at high bitrates? Can we safely use the last published set of results for Nero's encoder?

It has had several important bugfixes as well as quality improvements[1] since then. I know we always say this but it's true!

[1] <nitpick>TOS 8 violation!</nitpick>

On a P3 933Mhz, the nero encoder acheived 5.4x (36 secs) while CT+dimzon CLI (25 secs) one encoded at 7.8x (timed with a stop watch...)

3:16 song, CBR 64kbps HE-AAC

Gonna try with a longer track on my A64 3200+ (SSE2) later

If you want to reconvert yo aac (or m4a or mp4) audio to wav mono use ffmpeg with the aac codec and do:

ffmpeg.exe -i 2.mp4 -ac 1 test.wav easy

How do we add album art?

I found an interesting sample (it’s an artificial sound of a vehicle) taken from the Star Wars Episode III movie. I was able to ABX it all the way up to Q 1 (~420kbps) using some cheap Philips speakers (didn’t have my headphones around). The problem is located in the left channel, at the beginning of the track (0 - 0.4 sec), where there is some sort of distortion on those high frequency (~12khz) short “clicks”. If you find it hard to ABX, try a lower quality setting (for example Q 0.4) which will accentuate the problem, making it easier to spot.

You can find the 48khz stereo track which I used for the encodings (downmixed from a 5.1 channel, ac3 track) here.

Would the fact that it's coming from AC3 be an issue?

I am about to try using Foobar 0.9.1 to transcode some wv files to m4a using the new Nero codec. Trouble is I have no idea about command line stuff.

Can any of you chaps tell me the command line for Foobar to transcde my wv files to ~ 128 m4a files.

Sorry to be a bof (boring old fart)

Cheers

Thanks Garf.
I saw that

but didn't know what this bit meant

In my ignorance I thought that "something" had to be placed between the "if" and the "of"

Cheers

if = input file
of = output file

you'll notice there's an "-" inbetween, which means "standard input". This system avoids writing a temporary file and is supported by foobar2000.

So, it means, take input from standard input, output to %d (filled in by fb2k)

Cheers Garf!!

Just a little suggestion, to have minimum OS requirements listed on http://www.nero.com/nerodigital/eng/Nero_Digital_Audio.html
Specifically, so that folks like myself and others earlier in the thread who likewise downloaded the programme will know a unicode-capable OS is required. Looking at http://www.nero.com/nerodigital/eng/Nero_D...quirements.html gives a misleading impression.

Cheers.

Just wondering, compared to the moon-related one, is the Nero Month longer or shorter?
Or are we even in the second conditional already?

I think that "1 Nero Month" and "When it's done" is pretty much the same, at least for the customer.

I was wondering if a dev could take a look at a tagging problem that I've been having:

http://www.hydrogenaudio.org/forums/index....showtopic=44454

Basicaly, if I take a Nero-encoded file and tag it with AtomicParsley Foobar can't read it, but if I encode the same wav with iTunes then tag with AP, all is well.

Of course, if tagging gets bundled into the executable, this problem goes away and I won't have to try to rely on programs that try to "douche" foobar2000 tags.

We will issue a new update in the few days, which will among other things also include a command line tagger.

sorry for the perhaps lame question but is there a free frontend we could use?

its called command prompt

dbPowerAmp, Foobar2000, and apparently one is in development over at doom9.org. Look upward in this thread for more info.

Will this solve all the 'non-compliant tagging' disputes that several developers in the AAC/M4A world seem to blame eachother for?

And is it true Nero writes the tag at the end of a file?

Will that commandline tagger enable the single mp4 feature such as CUE sheet, album art, etc? The feature stated in the first post of this thread is:

"* Store Entire Audio Album in a Single .mp4 File with all the Features of an Audio CD embedded inside, but at a fraction of the space!"
