AAC encoder for XP

Although i don't use iTunes to fill up my iPod, i do like the AAC encoding it does (maybe it's just subjective, but i think AAC sounds better than MP3..).
Now my question: does anyone know a free, portable AAC encoder with cbbd capabilities?
Thanks.
Francis

As nobody else is willing to answer my question, I'm gonna do it myself:
Why don't you try PowerEnc by benware

AAC encoding, using Shuffle-saved iTunes for a Nano, file fidelity question

Love the little shuffle but don't understand possible limitations. I only have a Shuffle but may add a Nano. I'm trying to understand file encoding, decoding, etc..
When I upload a CD into iTunes (iTunes having been loaded upon initial Shuffle set-up) are the files automatically encoded as AAC files or are they saved in iTunes as the full-sized files (I don't recall the correct encoding for full CD-quality fidelity), or are they saved already encoded as AAC files?
While the fidelity of the AAC file is acceptable for in the noisy car or while running/skiing I would like to know whether adding a Nano to my quiver would allow me to utilize the 1000+ CD's I've already uploaded into iTunes, and whether the files in my current iTunes would load into the Nano as the higher-fidelity files. I would like to use the Nano to play tunes through my high-end stereo system and realize CD-like fidelity, not compromised AAC-level fidelity. Anyone familiar with all this? I would appreciate any help.

Probably currrently set for 128kbps AAC... go to Preferences>Advanced>Importing
where you can set the encoder to be whatever you want as well as the bitrate.

That's dependent on how they were imported...(see above)

You can keep your music in the library as AIFF or Apple Lossless and
set iTunes to convert the higher rate files to 128kps AAC on loading to the shuffle.

Free AAC Encoder plug-in for Media Live Encoder

Good morning,
I'm developing a little streaming project and I can't afford paying the MainConcept AAC Encoder plugin(U$ 249), recommended at FMLE's page.
Haven't somebody heard of any other free plugin for that?
Thanks in advance!

Unfortunately there are licensing costs that need to be paid to MPEG-LA for AAC encoding so this is not something that can be provided for free.

What's the recommended import encoding for best 'practical' ipod use?

I just really found out that you can change the import encoding for different quality sound and such and I'm wondering what is the best or most practical quality setting for use on my IPOD? Also how about the best, period? It would be nice to have my favorite albums on my ITUNES in the best quality I can have them.
Most of my songs are AAC encoded, 128 kbps, 44.1khz, low-complexity, stereo.
A while ago I was messing around and changed preferences settings and so some music is encoded as MPEG-1 Layer 3, 160kbps, joint stereo, ID3-v2.2.
How would you import?
Thanks!

Meg has a good memory. I do rip in AAC@256 VBR. After experimenting around for about 2 years or so, I have found that this setting yields the best audio quality for my tastes. You have to keep in mind what kind of equipment you are using. If you are using Apple earbuds & internal computer speakers, then it's doubtful that you will be able to tell much difference. I use Shure SE310 earphones & Bose Companion 5 speakers with my computer, so I can most definitely tell lower audio quality files. The last thing to remember is that ripping at a higher bitrate or with a Lossless format will increase the size of your files & thus use more room on your iPod. My AAC@256 files are 2x the size of the same files ripped @128. This doesn't matter to me as I recently purchased a 160GB Classic a few months ago. Hope this helps.

How can I import CD's with differing custom settings? IWhen I want to change settings the AAC encoder window does not appear because Itunes has adopted the first custom settings as default.

I imported a CD with custom settings for stereo bit rate, sample rate and channels. When I tried to import a second CD with different settings I could not get to the AAc encoder window that gave the settings options. The custom settings I had chosen for the first CD had become the default "custom" settings.

Hi there,

AAC Encoder at 320 kbps...

Hello all,
I'm new to the forum. I've had to erase my hard drive and ipod of everything so I've lost over 3,000 songs and have to re-import all of my music
The question is: I am assuming AAC Encoder at 320 kbps is the absolute best sound quality that I am going to get? I will be playing my music through my vehicle speakers and I want near CD sound quality!!!
The other question is: What can you tell me abou the other selections of encoders for importing?... I've searched the forums and haven't found anything, nor did I find a itunes manual.
Thank you all!!!

WAV and AIFF both are uncompressed audio formats.
WAV is mainly used on the Windows platform and AIFF on the MAC platform.
These formats can be read and edited by virtually all players and audio editors.
There's one disadvantage. They produce huge files of about 10 MB/minute of audio.
To reduce file sizes, people invented compression techniques.
Some of them succeeded in creating a codec (encoder/decoder) that will retain all audio information but reduce the file size to about half the size of WAV and AIFF.
Examples of these are Apple Lossless and FLAC (not supported by iTunes).
Your iPod (except the iPod Shuffle) supports WAV, but it will quickly fill up with those huge files.
Like Chris suggested, you should rip a song at different bit rates and try to determine what is best for your situation.
It all depends on your ears (hearing) and your playback system.
In my car, I can't even hear improvements above 128 kbps AAC.

Does AAC Encoder apply when importing or when transfering to iPod?

I have iTunes set to import using AAC Encoder. CD songs in the iTunes libary on my PC are m4a fles, while downloaded mp3 files remain as mp3 files.
Are the mp3 songs converted to AAC when transferred onto my iPod? Or does the AAC Encoder only apply when importing into the libary on my PC, in which case why do mp3 files stay as mp3 files?
Reason for asking is concern that converting from mp3 to AAC reduces sound quality.

Graham,
The import setting you select in your iTunes Preferences applies specifically to songs you add directly from a CD.
It does not affect songs that are added to your library that are already mp3's (or any other format for that matter).
Have a look at: http://docs.info.apple.com/article.html?artnum=301509
When you synch the files to your iPod they will remain whatever they are in iTunes - nothing changes in the transfer.
iTunes can convert files (see http://docs.info.apple.com/article.html?artnum=93123 if you're interested in details on that) but you are right, there is a loss of audio fidelity.

AAC Encoder Broken After Update to Quicktime 7.6

I have iTunes 7.3.1.3 and Quicktime 7.3.1.70.
After updating Quicktime to 7.60.92.0 every thing seemed fine. However, trying to import songs using the AAC encoder causes an error: "The current encoder settings for bit rate and sample rate are not valid for this file".
I can import songs using the other encoders just fine; it's just the AAC encoder that doesn't work. In fact, converting any existing library tracks with the AAC encoder causes this error - not just new new tracks.
After a little web searching I found others with the same problem after updating to Quicktime 7.6.
So I uninstalled Quicktime 7.6 and reinstalled Quicktime 7.3. Problem solved.
Anyone else have this issue, especially updating to Quicktime 7.6 only with an earlier version of iTunes?
I have never had an issue updating Quicktime separately from iTunes before.
At this time I do not want the aggravation of updating iTunes too.

Does it have to do with the fact that I installed quicktime 7 when I already had the 10.6.3 update?
Yes. Install the update again or this software.

Please prefix 'mp4:' to the stream name to record H264/AAC/HE-AAC encoded data at FMS using DVR...

I was able to modify the main.asc file in the application/livepkgr directory to include:
* DVRSetStreamInfo :
* This prototype was created to allow DVR recording funtionality to FLME to FMS
Client.prototype.DVRSetStreamInfo = function (info)
    var s = Stream.get( "mp4:" + info.streamname + ".f4v" ) ;
    if (s)
        if (info.append)
        s.record ("append") ;
        else
        s.record () ;
        s.play (info.streamname) ;
I get three status messages in the FLME encoding log:
Requested DVR command has been successfully issued to Primary FMS server for stream livestream1
Requested DVR command has been successfully issued to Primary FMS server for stream livestream2
Please prefix 'mp4:' to the stream name to record H264/AAC/HE-AAC encoded data at FMS using DVR feature
Now I have a few issues:
1. How to I fix the issue with the 3rd status message "Please prefix 'mp4:' to the stream name to record H264/AAC/HE-AAC encoded data at FMS using DVR feature" since the code above is prefixing the "mp4:" to the stream name.
2. In the applications/livepkgr/streams directory there is a file called "undefined.f4v" which is telling me the code above isn't passing the info.streamname variable.
3. Also, what do I need to do to playback this .f4v file. I've tried opening it with Adobe Media Player, but it doesn't recognize it.
I'm obviously using multi-bitrate streaming and that is working flawlessly. My goal is to record this livestream to later playback as an mp4 file.
Any ideas?
UPDATE:
I know on page 15 of the FMS 4.5.1 developers guide, "Configure DVR (HDS)" under "Publish a DVR stream", it states "To Publish a DVR stream from FLME, DO NOT check Record OR check DVR Auto Record. Publish the stream just as you publish any live stream. In the next section "Play DVR streams" is states that I can use SMP (Stobe Media Playback), which I am. So that brings up two more questions:
1. Why is my SMP Player not displaying the DVR funtionality (See image):
In my SMP configuration, my streamType is "LiveOrRecorded" - default. There is a streamType = "dvr", but will I lose live funtionality?
2. If I want to later on, package the stream into an mp4 file and play it back later for those who missed the live stream, what is the best approach for that?
Message was edited by: giostefani

Two things: You need to have "DVRCast" application on server-side i.e. "dvrcast_origin" for DVR recording to work and secondly for mp4 recording your stream name should be "mp4:<streamname>.mp4" while publishing.

Zen doesn't play .m4a encoded with Nero AAC encoder = Creative, please create a firmware f

The Zen doesn't play AAC encoded with Nero's AAC encoder, which is unfortunate since it's the best one out there. It does, however, support iTunes-encoded AAC. There was a brief discussion on it elsewhere, but I'd like to focus the discussion here on:. Request for firmware fix by Creative, so the Zen will read the files: ple2. A fix to get the files to play in the current firmware?Many of the references in this forum to wishlists, tools etc. are dead links, so hopefully?this thread will generate some answers for those of us out there with sizeable Nero AAC-encoded?music libraries.

Very Good!!
I'd just like to report that m4a files made with winamp and then repackaged with your application have a problem in fast forward and rewind. That is, (Sorry for my English, please try to understand) when you fast forward to a point, the player correctly jumps to the desired point, but, after that, the playback bar starts again from 00:00:00, even if the player is in the middle of the song.
Anyway, this doesn't corrupt playback quality and doesn't create audio gaps; moreover, it just happens with the zen, while winamp works correctly.

About the AAC Encoder

I chose to use the AAC encoder. But after I encode a song, it appears to be .m4a .I thought it should be .aac .What is happening?

Nothing unusual: iTunes uses .m4a as extension for unprotected AAC files + .m4p for those that are purchased/protected.

Audition AAC encoder information

Hi,
I am doing some research in perception codecs, and need some information about the AAC encoder. I cannot find any information about this, and Adobe support sent me to the forums for an answer. This question is therefore primarily directed to the developer staff.
- Which vendor supplies the encoder
- What version of the encoder is used
Any other information that relates to the AAC encoding in Audition is greatly appreciated!

Great prompt SteveG(AudioMasters). Also, thanks for also jumping in ryclark.
The basic answer is that on Windows we use Media Foundation (Microsoft Media Foundation (Windows)), and Audio Toolbox (Audio Toolbox Framework Reference) on OS X. So the underlying encoder is owned by the operating system and can technically change from OS version to OS version.
That's specifically for current releases of Audition. In Adobe Media Encoder, the AAC encoding is licensed from a third-party and is different than what is in Audition.

AAC Encoder in iTunes 7.5: significantly improved!

Upon the reported 'problems' with the AAC-encoder in iTunes 7.5, I did a short analysis upon a self-created reference track (amongst others, containing lots of silence) @ 320 kbit, (supposedly) CBR AAC and MP3 encoding, and compared these to the previous version of iTunes. Here's what I found:
AAC:
1. Silences are encoded much more efficiently, leading to a reduction in file size (in this case) of about 50%
2. The residue (the AAC-Waveform 'subtracted' from the original waveform) is four times smaller compared to the iTunes 7.4 encoder. (Although this is no real measure of the encoder's quality, regarding psychoacoustics and all that!).
3. Furthermore, the amplitudes of pre-echoes, a significant compression artifact, are also reduced to 50% compared to the previous encoder.
As for the indicated bit-rate, it's just the average for the entire file. Regarding the above, even if it indicates less then 320, you still get more.
MP3:
1. The better encoding of silence has also been applied in the MP3-encoder, however only leads to a reduction of file size of about 25% (this is probably the maximum the less efficient MP3-format allows).
As for the rest, the MP3-waveform from the 7.5 encoder (including all its artifacts) has remain ex-act-ly the same compared to 7.4, really, to the last bit. So the benefit only concerns storage here...

The codec is closed source, so there's not a change log (that I know of) to look at. Probably the best source of information on the status of iTunes AAC would be in the way of listening tests on Hydrogenaudio.

Encoding for content in KM

Hi All,
I'm modifying and updating an existing file in KM. I use DOM to parse the file and update it as follows:
Element rootElem = doc.getDocumentElement();
<code to update rootElement>
Finally, I want to convert the Document or rootElement to IContent and update it in the repository. I use the following code:
IContent newContent = (IContent)MimeUtils.getContentFromString(rootElem.toString(),"text/xml");
IContent newFile = new Content(newContent.getInputStream(),"text/xml",newContent.getContentLength(),"ISO-8859-1",null);
resource.updateContent(newFile);
The file is updated with the above code, however the encoding "ISO-8859-1" does not seem to be set. There are spanish characters in the file and upon opening the updated xm file in the browser, I get "Invalid character" errors for the spanish characters..
Is there an alternative method to set the encoding for the created "Content" object? Appreciate any pointers on this. Thanks!
~Prachi

resolved by creating content from the string "<?xml version="1.0" encoding="ISO-8859-1"?>" + rootElement.toString()

Live Video encoder for Mac. Does it exist?

Looking to d a live video stream. Would like to use Vp6 I do not think Adobe had a Flash video encoder for the mac.
As always, thanks for your time and help.

There is no Airscan :-)
but you can scan wirelessly on any your OS compatible network scanner of MFP printer with a scanner.
This has to be connected to your network either via WiFi or Eth cable.
