Although not posted on the website yet, here is the install:

ftp://ftp.nero.com/nero55100.exe

With MPEG-4 AAC support
Limited to 50 encodings and 30 days of decoding.

Other changes I don't really know, just wait for the changelog to appear on the site.

Have fun.

Menno

Ok, rules for highest quality encoding:

1. Go to "preferences / plug-in look up / defConvertor" and set resampling to SINC , quality 100 for other purposes (combo box that allows selection between "playback" and "other purposes" - this will enable highest quality resampling available in NERO

2. Switch to "high" encoding quality for MPEG-4 AAC plug-in Default is "medium" which is also good quality, and 30-40% faster - but with small degradations

I shall download it and i shall check it out. Congratulations, finally out .

Decoder is, of course, able to read QT6, FhG MP4 and all other MPEG-4 compatible AAC audio files that are more-or-less compatible with the MPEG-4 specs

You can also open .mp4 files in WaveEditor, play them with NeroMix - and directly burn them to CD as WAV files, or export them (during encoding) to MPEG-2 ADTS files for Expanium and similar devices.

Maaan, encoding speed is finally reasonable.

Which 'AAC profile' should I use for 128kbps cbr?

Ouch, are you sure you want to use 128kbps CBR AAC?.. Or just for testing (me don't know, ivan has answer )
edit: I say that because it's known the for best results you should use VBR.

Use LC always - because compatibility with future hardware and I suppose no LTP decoders will be supported in near future.

thanks for the heads up on this

I've tried LTP, but IN_MP4 plug-in reports 'MPEG-4 AAC LC'. What I'm doing wrong?

K, thx.

Ya, you're right, i'll check the lower vbr profiles. I need the bitrates to be close to 128kbps.

I have another problem using CBR modes. If I choose for example 320 kbps, in_mp4 and Nero AAC decoder reports 262 kbps, and this happens with all bitrates (64 kbps and decoder reports 56 kbps).

I must be blind because I can't find anything that is named "defConvertor"...

Edit: Aha, found it... "Converters" was the name... Guess I'm blind...

is there someway to disable nero to do on-the-fly encoding ? i really hate all the seeking my cd-drive is making.

also
will there ever be a command encoder again that can be used with alternative rippers ?

VBR Normal HI ADTS plays perfectly in my eXpanium EXP-301. No artefacts noticed yet, it's late and this short testing session ends here. If we can't have a command-line encoder, will it be possible to batch-convert files in later versions?

"Extras/File encoding...", perhaps?

Well.. this is something that needs to be discussed with executive management

Hey Ivan, I'm ripping a DVD movie and I would like to convert the ac-3 audio to AAC, what is the quality setting do you think I should use?

I've just tested it with some problems:

1. The *.mp4 file created by Nero using Normal preset and Low Complexity was unplayable in winamp (using the in_faad.dll which comes with Pystel encoder).

2. The encoder doesn't seem to have an option to output as *.aac, which is the only extension my Expanium will accept.

3. The decoder doesn't accept *.aac files created by Pystel.


On the plus side however, the encoder is twice as fast as Pystel 2.15 (on the same track using -normal VBR preset, with high quality in Nero); this makes it much faster than Vorbis or lame VBR (but still miles slower than musepack).

Also, the decoder doesn't seem any slower than the mp3 decoder in Nero (I get 9% CPU usage for both when burning at 12 speed) which means I can burn audio CDs at 48x on the fly:)

You can solve all your problems using MPEG4IP tools. (You have to extract the AAC track from the MP4 file/Put the AAC track in a MP4 file).

For the first, you can also use the updated in_mp4.dll that uses FAAD2 decoder.

What a long strange trip it's been!

I'd tried the MP4 plugin. The quality is good till "Radio VBR quality". The "Tape" quality is not acceptable as the human voice has been changed and I hear flanging/ringing effects.

Edit: The CBRs, although qualities are lower, it's less artifacts being detected. Overall the plugin is really a great great job. I wonder whether it's possible to put SBR technology in it for the next release of the plugin?

Halleluja!

Kyrie eleison!

Try the latest in_mp4 plug-in, or export files as .AACs (see the next answer)

MP4 files generated are accepted with in_mp4, Envivio plug-in (RealOne, WindowsMedia, QT5), QuickTime6, etc, etc..



It has - take a look "export to ISO 13818-7 AAC file" - I have Expanium and these files work perfectly with it



That is, unfortunately, true

Right, you have to use resampling with the lower quality presets of PsyTEL/Nero. The difference between them is that Nero now uses resampling outside of the codec, if I understood Ivan correctly. So have a look around in the app where you can find an option that lets you resample the WAV before/while encoding. A sample rate of 32 kHz is a good start, maybe even 24 kHz would work now (PsyTEL crashes with this frequency) together with the -tape preset, although its cutoff is probably still at 13 kHz, so Mr. Nyquist would have to raise his finger again.



The low bitrates (CBR) have been fixed by Ivan, maybe he should look again at -tape and -radio (both VBR). And aacPlus, well you know...

32 kHz sampling rate is used for tape and radio presets - resampling is performed by NERO ("Ahead RAW Audio Convertor")plug-in)

24 kHz is used.. let's see.. for 56 kbps stereo CBR and 28 kbps mono CBR.

FYI, the latest faad and mp4 Winamp2.x plugins (CVS as of 12 Dec) are available here. The link will be valid for all subsequent updates.

EDIT SORRY!!! Now corrected.

Link not working for me (right now at least ).

Good idea... shall I give you the number of my bank account? By the way, it would be great if there was some kind of change log or whatsnew.txt or even a manual where one could compare the changes you've made from PsyTEL v2.15 to Nero's plugin. Or is this top secret? The same would come in handy for every new release of Menno's plugin, so we wouldn't have to guess what happened since the last time.



Maybe this would also be better for -tape, combined with a cutoff at 12 kHz? Because VeryBlur is right, AACEnc reaches its limits at these low bitrates, and 13 kHz lowpass with 32 kHz sample rate is still a bit too optimistic in my opinion. I wish I knew how FhG tuned their evaluation build... I guess they used Temporal Noise Shaping more than usual, because I can hear related artifacts on two occasions in the c't test file, but only if I switch on my "TNS detector".

The decoder code used in Nero is the same as the code in CVS.
I think a 2.0 version of the FAAD2 library is not far away, I'll distill the CVS changelog for a good changelog by that time.

Menno

Hmm - list is very very big, let's see:

1. Almost completely redesigned psychoacoustic model, with better PNS implementation

2. Better bit-reservoir management and bit allocation

3. Completely new TNS algorithm

4. New "fast" encoding mode - which is 15.4x real-time on P4 1.8

5. Much more MMX/SSE/SSE-2 optimizations

6. Direct support for MP4 file format

7. Medium quality preset, with 32-bit floating point arithmetics, quallity is only little bit worse than "high" - but the speed is 30% higher (sometimes even more)

8. Overal speed optimizations of the algorithm - 100% faster execution speed

9. Many glitches and bugs fixed

I'll think about tape and 12 kHz cut-off with 24 kHz sampling rate...

ye, link insn't working

Well done Ivan Nice work.

To me, it's a real shame it's wrapped up inside Nero though. Plus I'm gonna have to pay for it, ontop of the fee for Nero 5.5!

The speed improvements are great, up to 2x realtime on my pc!


I do have a complaint about the quality though.. Remember the NiN sample you posted with the background noise in there, it sounded like it was stuttering and badly mp3'd... I did a little trial and noticed it has happened in other places.

Nero encode
Psytel encode

They both sound like ass because they're -radio.. I'm sure the people here could hear the difference up to -streaming though I imagine.

Also, how come when encoding a file, the speed indicator works its way up from 0? It takes about 5 seconds to get up to full speed (that isn't exactly an earth shattering bug though!)

Thanks...

There was a spelling error http://homepage.ntlworld.com/jfe1205/faad_plugins.zip

Very interesting, thank you... I think I'll extract this list to a text file and keep it in my PsyTEL directory.

Ivan,

I found a bug on the MP4 plugin for Nero. When I finished encoding a song using 40kbps CBR, after that I switch the mode to 96kbps CBR, the sampling rate for the encoded output is the same as 40kbps CBR i.e. 22kHz. I thought 96kbps CBR should be using 44kHz sampling rate instead? Hopefully this information could help to improve the quality of the plugin.

bump, a little help here???

give it a try yourself. I would think the -streaming preset or 128 CBR would be ok.

I second that... maybe 96kbps is good also...

Yes - It seems that this is a bug - workaround is to remove file and add it to the file list again- 96 CBR has default sampling rate of 32 kHz btw.

yup...


????????????

what e hell... funny...

i thougt.. the general idea.. was to make a "transparent" plugin..

is this a technical issue..?? or another of aheads bad ass desissions..!!

I tested that, there is no problem with decoding PsyTEL files, it works prefect, but only if they are muxed in mp4. You cannot load *.aac So it has nothing to do with the encoder, it is about the file-format. If you want to decode aac with nero mux it to mp4 first with mp4creator:
mp4creator -create=infile.aac outfile.mp4
Anyway it would be nice if it would support .aac file-format, too.

yup...


in other words..

i need to mux. around 30 CD`s.. for this wonder to work..

think not.. back to BAO.

does mp4creator support wildcards like this
mp4creator -create=*.aac *.mp4
?

Speek's Psytel encoder frontend can do this automatically for you. It supports mp4creator, so it is the quickest and easiest way to do batch operations like this.

edit: Here's the link - Speek's AAC Frontend

Jordan

Speek's "Ivan & Menno" can't create .mp4 files, only .aac. It doesn't support mp4creator.
edit: this is wrong outdated information, read on .

my probesm it all my AAC files i wsih to make to .mp4

doing it by one commandline for each is gonna be hell

If you read the description on his site, you will discover that it does support mp4creator. It was updated a few weeks ago to support mp4creator. You even replied to that thread, SK1. This allows you to change your aac files to mp4. To do this, put mp4creator and Speek's frontend in the same directory. Using Speek's frontend, add all your aac files, make sure mp4 is selected in the encoder section, and press convert. I just tested it right now and it works perfectly. No typing into the command line endlessly .

Edit: Thread Link - AAC -> MP4 batch codec available

Jordan

edit: ah I reread the next post, not what you needed...well, never mind about that, but hey this is still very handy though

If you mean to rename your extensions, Grab Oscar's File Renamer here, its free. It'll do it all at once, a very handy piece of freeware.
