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

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 ..."


I already added a nice progress display a few days ago

Many thanks, but where this version is available?

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.

What version of CDex did you use?

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


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!

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

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
Quote
-ignorelength -q 0.5 -if - -of %d

but didn't know what this bit meant
Quote
-if - -of


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)

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.

Sounds really promising, wish I could give it a try. How long till the UNIX version? Can you elaborate on that?
Thanks a lot for the generous offer.

Either

1 Nero Month.

or

When it's done


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.

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!"
