I assume that new Nero 7 Premium edition include brand new Nero HE-AAC v2 audio codec,am I right. Is v2 of HE-AAC better then Coding technologies AACPlus v1 and v2 AAC, or not.

The new Nero HE-AACv2 encoder will be in the web release.

Nero Digital and aacPlusv2 are both implementations of the same HE-AACv2 standard.

Since the new Nero encoder is not public yet, nobody will be able to answer your question.

Ok,but can you promise me an answer on my question when web release of Nero 7 came out.Thanks.

You can be more than sure that the two encoders will be thoroughly compared
once the new Nero encoder becomes widely available.

No need for anyone to promise it.

Dear Graf, do you have any ideea whan n7 will be released?

the nero homepage states, that nero 7 will be available for online purchase on october the 26th. i assume it will then be possible to download the web release.

Is the Nero encoder (I have it) compatible with the industry standard?

You do not have the HE-AACv2 encoder. You can have the HE-AACv1 encoder though, that one has been available for a while.

All Nero products are fully compatible with the MPEG standards.

Nero 7 is OUT!

Yes it is, no doubt now. Garf was right about very listenable quality @ 32 and 48 kbps

Have you done a blind listening test comparing it to Winamp 5.1 encoder?

No I haven't, ain't got time at the moment.. But I know how my favourite songs sounded before with Winamp AAC encoder and now, they sound different with Nero encoder..they sound definitely better at the same bitrate. I am 99% sure about that

Same for me. Difference between all HE-AAC2 isn´t so big. but Nero is best for me. Top bitrate for PS is aprox 51 kbit/s.

Well, let's not get into a massive TOS8 violation spree here.

But it would of course be appreciated if someone would set up a proper listening test [1], so we can settle the matter.

[1] Proper meaning: performed by more than 1 person.

WARNING

Seems like there are wrong channel mapping in 5.1 encoding using BeSweet! (There are significant audio fluctuations). Can anybody check it too?

There are 3 variants:

1. Wait until Nero fix the problem
2. OR Ask DSPGuru to change channel order for bsn
3. OR Write tiny wrapper around original bsn.dll and change channel mapping in it (i can write such wrapper for -dimzon switch but i need information which channel mapping reqied for Nero7)

Hi!
I got my long-awaited brand new Nero 7.0.1.2.Now I got some questions:

1)For Dimzon:what's the name of the utility you're using (file info) and where I can download it?
2)Converting to aac 48 kb/s I don't see any option for setting parametric stereo.Where is it?
3)Getting the info file (using winamp) about a aac track converted by nero,the profile is always LC instead of HE (effectivly used).Why?

a recent foobar2000 0.9 beta



It's used automagically when it's beneficial.



Because Winamp is buggy.

Workaround

Garf
Plesae can You tell us whats exatly new in new Nero encoder (new psy model, which improvements etc) ?

Does PS part works for 5.1 encoding?

Basically everything was improved. In terms of features Parametric Stereo is new.



Parametric Stereo is not defined for more than 2 channels. There is work in progress at MPEG to define a multichannel version (Spatial Audio). When that is finished, we will support it.

Can newest Nero AAC encoder work from some other program, etc. dBpowerAMP Music Converter, or freeware Mediacoder 0.32

dBpowerAMP Music Converter already support older version of Nero AAC encoder from year 2004.

Yes!

Please explain? When the newest Nero AAC encoder will be adapted with newest dBpowerAMP Music Converter 11.5, on their site there is no information about that.

so what's the difference between the "high" and "fast" modes now?

Nero7 has same API so you can still use dbPowerAmp

Fast mode uses simple scalefactor estimation to gain speed - high mode uses SFE + additional noise shaping processing. Also there are some differences in precision etc...

The difference (quality, speed) between HIGH and FAST is now very small. Both modes react in the same way. Sometimes, I get identical results. It seems that both modes are sharing the same engine (it was very different with previous encoder). Could you confirm?

You can see high mode as fast mode + optimization process.

Garf
Nero7 effective bitrate for HE-AAC in VBR mode is higher then Nero6. Using same sample to comress -vbr_tape i get ~32kbps @ Nero6 and ~40kbps @ Nero7. Why?

It seems that the previous fast mode worked differently than the current one. The previous FAST encoder was used to bloat the bitrate with some stuff (highly tonal samples, harpsichord...) and to keep a great quality with these samples; current encoder has now a much lower bitrate and (much) poorer quality (edit: with these samples, and with both HIGH and FAST modes).

Nero team will not change anything because of one person's listening test result. But I'd suggest making the bitrate bloat / bitrate uncertainty an adjustable parameter that can be altered by the user.

Actually this will be changed, but in a better way.



N7 vbr_tape is using Parametric Stereo core - and a different internal VBR preset.

there are same effect for vbr_streaming and vbr_normal too

Due to different VBR engine bitrates could be different - some people, i.e. complain about smaller avg. bit rate for the normal preset.

for LC avg bitrate is smaller but for SBR avg bitrate is always bigger

And one more question - why your encoder support SBR encoding @ bitrate bigger then 40kbps per channel? LC encoder sound's MUCH better or such bitrates...

What about LC-AAC mode in newest Nero 7 AAC encoder? What is improved here? I mean on 128 kbps, 192 kbps and 256 kbps bitrates.

HE-AAC is not defaulted for those bitrates, is it?

Quality is better. ("What else did you expect?")

That sums it up pretty well. I would much prefer a proper test, as I already said. We will not revise the tuning based on one persons result, and I hope that other people don't base their decisions on just that, either. We did internal tests and decided that the current settings seem to be best, and are an improvement over the old encoder, fast or high mode.

Garf
Does You perform internal listening tests during encoder developmen/tuningt? Can You public results?
Thanx!

Yes, of course...



I don't want to do that. (Well, the encoder is public, that's one result of those tests!)

One more thing. Garf, you said that new AAC encoder can be used in DbPowerAmp 11.5.With that program, I encode WAV files into AAC.

Question is: If I install Nero 7.0.1.2 on my computer, will DbPowerAmp 11.5 automaticly start to encode in newest AAC encoder.

P.S. I installed from their site plug-in who enables Nero AAC support.

Yes it is working alright, I've been using the same for two days already..

And what N7 presets other than vbr_tape does use PS core by default?

cbr 24 kbps
cbr 32 kbps
cbr 48 kbps
vbr_tape
vbr_radio

There is new version of CD-DA extractor http://www.poikosoft.com/
It has a fresh HE-AAC2 from Codingtechnologies.

You can get aacPlus v2 CD-extraction for free with winamp and aacPlus v2-transcoding with the transcoder-plugin.

You should know of http://www.hydrogenaudio.org/forums/index....68

Transcoder never worked for me and many other...
Anyhow, I'm using that ghetto aacplusenc.exe command line tool

Something has changed in Nero 7, if used from an external program it times out after 30 or so encodes even though it is the full version.

It is on our fix list, could be something as simple as the nero stuff needing the active folder set to \nero\, could be anything.
