Does iTunes normalize audio when converting to AAC?

Most of my mp3s are not normalized. I want to normalize these tracks before converting them to AAC. Does iTunes normalize audio when converting to AAC? Or do i need to normalize my mp3s first, then convert them to AAC? Thanks!

What exactly do you mean by "normalize"? Do you mean leveling the volume?
iTunes uses the soundcheck feature to do this. It doesn't automatically happen when you convert a song to a different file type.
Apply it in iTunes using the edit/preferences/playback menu (Windows).
Turn it on on the iPod using the settings/soundcheck/on menu.
After applying it in iTunes, sync your iPod to reflect the changes made.
There are 3rd party programs that do this more effectively (at least in my opinion).
For Windows there is mp3Gain/aacGain.

Does iTunes sync metadata when syncing photos to an iPad/iPhone? I am using Aperture v3 as my photo library.

Does iTunes sync metadata when syncing photos to an iPad/iPhone? I am using Aperture v3 as my photo library.

This might sound weird, but here's an idea which worked for me re music that was newly added to itunes and showed up in my ipod but wouldn't play - I simply played the tracks in itunes first, just a second of time or so will do it, not the whole track, then connect the ipod and sync again and this time they played - hope this helps.

ExportPDF does a poor job when converting pdf tables to MS Excel tables - Any advice?

ExportPDF does a poor job when converting pdf tables to MS Excel tables.
The resulting file had several lines merged into one and had strange font sizes and line heights and widths.
If needed, I can send both files to show what happened.
I am using Adobe Reader 10.1.4, with Adobe ExportPDF (unknown version, bought Oct 4, 2012), MS Excel for Mac 2011, version 12.2.2 (120421) on a MacBook Air with Mac OS X version 10.7.4.

I have the same problem. I would like to convert bank statements to Excel but am only interested in the transaction history. Is it possible to select only certain parts of the document as a template for other conversions?

No Audio When Converting Videos For iPod

whenever i convert video files for my ipod they do not have audio. i have tried several programs, and none work. i have read other discussions about this, and found that MPEG Streamclip worked for other people, however whenever i try to convert using this program, it says "Error: Can't Prepare The Movie" Can anyone tell my why i can't convert these videos? i cannot figure it out. thanks alot.

I am not sure what you mean when you ask what the "compression formats" are.The compression formet refers the manner in which the media was encoded and, by extension, how the media must be decoded. I.e., it determines which codec (encoder/decoder or compressor/decompressor) is to be used with the media file.
If you can tell me where to find those i could tell you what they are. I can, however, play the video in itunes, quicktime, and MPEG Streamclip.Simnce the files are playable in QT, the most common place to look for codec information is in the "Show Movie Info" window following the "Format:" entry. E.g., it might say:
Format: MPEG2 muxed, 640 x 480orFormat: Apple MPEG4 Decompressor, 320 x 240, millions
AAC, Stereo, 48,000 kHz
i also am not sure if there is audio in the source file.Do you hear any audio when the original file is played? If not and there is no audio track (or "muxed") information, then there may not be any sound for you to convert in the first place.
how do i find out if it is muxed?If it is "muxed," the format entry we say so. In this case blocks of audio data and blockes of video data are interspersed in a single data stream (track). This is the normal way MPEG-1 and MPEG-2 audio/video data is synchronized. In addition, these formats commonly lose their audio content when converted using QT Pro, iTunes, iMovie, FCE, FCP, or other QT based "frame-to-frame" synchronized workflow. (In the case of MPEG-2 in MPEG Streamclip or QT, the QT MPEG-2 component must also be installed in order to convert the video data alone.)
most of my videos that won't convert for an ipod are downloaded from the internet. how can i find out if they are corrupted or incomplete?Internet files should always be considered suspect -- especially if they come from a peer-to-peer source. Messages that indicated QT cannot open an otherwise fully compatible QT format is often the best indication that there is a corruption problem or that the files were improperly closed at one point or another.
most of my videos that won't convert for an ipod are downloaded from the internet. how can i find out if they are corrupted or incomplete?Normally ypu would post them to a web site or FTP storage area and post the URL. If files were downloadedd from a particular web site (e.g., a QT movie trailer), simply post the URL for the particular web page.

Lose audio when converting avi to mp4 on quicktime

I've read the discussions on this but can't find a fix so far.
When I try and convert an avi file to mp4 using either quicktime or MPEG Streamclip, I lose the audio. I don't believe I need to download the quicktime mpeg-2 component for mac osx given I have 10.9.1, but perhaps I do (there is debate on this and I'm confused)?
I tried downloading MPEG Streamclip 1.9.3b8 but it seems to want that component to attach itself. Should I therefore buy it - will it work?
Alternatively, should I buy quicktime 7 pro? I really don't want to.
Can somebody help...please?

So I made a successful and audio distortion free ACC/AAC mpeg4 (.MP4) video from Sony Vegas for the Ziio. You are given a choice of audio (I chose 92kbps). The problem is solved. No more distortions. And all this time I was doing twice the work by importing the MPEG- files into Any Video Recorder and converting to .MP4. That was the distortion result. Hope this helps if you're doing the same kind of work by combining video and audio. Otherwise, it's up to you...

How to preserve embedded artwork when converting to AAC 128kbps for iPod?

Hi
I am using the new 'convert higher bit rate songs to 128 kbps ACC' option in iTunes 9.1.1 (12). All of my artwork is embedded in Apple Lossless files, but on conversion to AAC for the iPod this embedded artwork gets stripped out of the file. Instead I am getting about 12 ithmb files in the iPod_Control/Artwork/ folder totalling about 6GB which probably corresponds to all the embedded artwork for all the tracks, i.e. 20000 tracks x 300KB = 6GB, and an ArtworkDB file, which presumably is for CoverFlow.
Because I use PodWorks to backup my iPod Music to my Mac I would like all of the artwork to stay embedded in the AAC files, so that it gets uploaded to the Mac. Artwork stays embedded when you make an AAC version of an Apple Lossless track in iTunes normally, but not it would seem when transferring to the iPod. And if this new method of encoding on the fly to the iPod can't preserve embedded artwork then it makes little sense to clog up the iPod with 6GB of artwork!
I am wondering if there is any setting I am missing to get this working, or if this is something Apple still need to get around to sorting,
Thanks
Nick

Please!!
I'm not silly...
As I said, selecting View actual size shows the image with sometimes drastically impaired quality (regardless of the window size).
I also said I have preferences set to view at 100%
It now seems as if this is only happening with scans I've made here.
Images downloaded from the internet are converting indentically, no problem. But my scans are being resized when converting.
I wonder if anyone with a bit of technical know-how can give me some clues as to why this is happening. It would seem to be something to do with the file itself.
(There was another post on here with the same problem but for some reason its been 'archived' though the last posting was this month and the query was not answered. So I've posted the question again.)

When converting to AAC?

I just got my iPod Nano and I have about 1700 mp3's now I'd like to convert them a little at a time to AAC because converting them all at once will take all day. But when I convert say 100 and then try again if I already converted a song it doesn't skip it it will RE-convert it using up valuable time. Any ideas how to tell iTunes to skip tunes already converted? Or do I have to keep track of each and every song?

AAC is usually better quality than MP3 at the same bit rate.
AAC 128 kbps is usually at least as good as 160 kbps MP3 but ~25% smaller file size.
When converting, you should always start with the highest quality possible. Since AAC and MP3 are both lossy, when converted to this format the first time, you lose quality. Convert them again and you lose more quality.
If you are going to use AAC, convert from the CD.
If they are already MP3 and you do not have the original, leave them as MP3 as you will simply reduce the quality.

Hi braambotha,
The most likely cause of this issue is that the PDF wasn't tagged properly to indicate the table cells, so Excel has no idea where to place the content in the converted file. Do you know how that PDF was created, and in what application?
You may have better luck saving directly to Excel from within Acrobat. You're welcome to try Acrobat for 30 days to see if it suits your needs. For more information, see www.adobe.com/products/acrobat.html.

ITunes 10.7.0.21 (and earlier) on Windows 7 64bit crashes when converting to AAC

iTunes crashes very consistently whenever I try to convert songs to AAC format. Sometimes I can get one or two songs to convert before it crashes, sometimes it's on the first song.
I have had this problem for over a year now, on every version of iTunes since I first installed it. I have tried reinstalling iTunes over itself, uninstalling it and installing it again, etc. I've been through Google and Apple Support Communities multiple times and none of the suggestions have helped.
I am hoping someone has had this problem and found a solution that they can share with me.

I had the same problem. New iPhone 5, had to install iTunes 10.7 on windows 7 64 bit. The install worked, but it crashed immediatly after startup (no window, nothing.) I tried repairing the install, and still nothing. When I read the post above, I saw that it was Quicktime related, and remembered I was also prompted to upgrade Quicktime too, which I chose NOT to do. So I went back and upgraded quicktime.. and VOILA.. it WORKS. iTunes now runs, and I'm in the middle of restoring my old iPhone to my new one. (fingers crossed)

Why all the duplicates when converting to AAC?

I need to convert all of my songs in iTunes to AAC. Unfortunately, as I do this iTunes is creating duplicates and these get synced to the iPod, leaving me with two of each song.
Why is this happening and, more importantly, can I prevent it and/or get rid of the dupes?

StarDeb55 - I'm using iTunes on Windows to do this, so that's why I posted it here. I should have have changed the OS listed in my post.
Thanks to everyone for the help. I'm doing a batch at a time and then deleting the old files. It's pretty easy when I sort by "date modified" and then just delete a bunch at a time.

Losing Audio when converting videos to work on IPOD

Hello,
I have loads of small home videos I took using a pretty basic Hewlet Packard Camera. They are just MPG files and when I dragged them over into ITUNES then tried to sync them into my IPOD it did'nt work.
I followed the instructions and used the option in the advanced settings to convert them into an IPOD version which seemed to work. However when I sync'd then over to my IPOD they transferred across and look fine but have no audio.
Does anyone know if it's possible to sort this or are the video clips just not completely compatible.
Thanks
Craig.

Try using MPEG Streamclip to convert the videos; more information on this issue is available in this article.

No audio when converting ipod videos

Hello Apple,
When I try to convert my video for Ipod use, I can see the video, once converted but I don't get any audio!!!
What can i do to resolve the problem?
Thanks for your help,

Multiplexed video ("muxed" where the video and audio is combined on one track) cannot be converted for use on the iPod by using either iTunes or Quicktime. As you have found, if you do this, there is no audio track.
You must use a 3rd party converter.
I have used MPEG Streamclip with good results (albeit on a Mac). There is a Windows version.

Missing Audio when Converting from MPEG1 Muxed to Ipod using QT Pro 7

I just got my video iPod over Christmas. After reading up on QT Pro 7, I purchased it over the weekend, and have attempted unsuccessfully the past two nights to convert home videos (taken with my Sony digital camera) to iPod format. My home movies play fine when I open them in Quicktime; however, when I export to the iPod format (and also when I export to mpeg4 format), I only get the video and not the audio.
I've confirmed that my key for QT Pro 7 is successfully loaded, so that's not the issue.
I've also confirmed that the format of the original video taken from my camera is "MPEG1 Muxed". Several internet discussion boards seem to indicate that missing audio is a common problem for people using Sony cameras and Quicktime. If this is the case, I'd prefer to simply refund my money and buy one of the other video to iPod converters available on the web.
So, either help me solve this problem, or help me get a refund. I'm fine either way.

Trouble with audio when converting MPEG to iPOD Video

I am following the Quick Time Pro instructions for exporting my mpegs to iPOD video format, but when I do not get any sound. I am using Kazaa to download my mpegs. Is that the issues? I don't want to pay for videos on iTunes already formated for my 5G iPod. Can you help

QT Pro does not handle "muxed" formats (MPEG1, MPEG2, VOB, some AVI, AVI MJPEG, etc.). Use an MPEG based third party application like Videora Converter.
