Converting ac3 files into mp3

Does anyone know if I can convert ac3 files that are created by compressor for DVD Studio pro into MP3 files?
Cheers

Hi:
You can use MPEG Streamclip to extract the audio tracks from your DVD and re-encode them as AIFF. Then use iTunes to convert to mp3.
I have just tried and Streamclip doesn't take just the ac3 file, you need to take them from the VOB files.
Hope that helps . . . and hope you own the rights of the material !!

Urgent How to convert wav files into mp3?

Can anyone plz tell me how can i convert wav file into mp3 using JMF? tell me any sample programme, any method in JMF........ help me plz

Examples could be found on the JMF Solutions page.
Only I can say about mp3 through network - it's hardly possible. I recommend GSM for compression2transmit. It could be used via GSM content descriptor. I'm not sure, but I suppose MP3 is supported only for files, there's no MP3.RTP or such (if you want to transmit files, it should not cause any problems).
About JavaSound - it does not matter... You still need JMF to be installed on Client, and AppletCapture to be enabled. Futrher - would it be DirectSound, JavaSound, or anything else - just the deal of JMF.
I tried to use JavaSound capture with proceeding AudioInputStream to JMF, but failed to do this.
About your problem - best solution seems like that:
capture sound
put it into processor
set format to GSM
transmit
so then, server receives it and formats it as it likes.
If you want to transmit exactly files, you should use just some of pure java after capturing. java.net, or such thing.

How to convert AMR files into MP3 or WAV?

Hello,
I'm not sure if that's the right place to ask, but I couldn't find any more suitable one, so...
Can anyone recommend a nice convenient application to convert my phone's recordings from AMR format to MP3 or WAV - eg. something I can conveniently listen to on my PC?
Thanks in advance!

Many of my friends recommend iDealshare VideoGo to convert AMR files to MP3 or WAV.
Today i just have a try, and find it really works great in converting AMR to MP3, WAV, WMA, AAC, AIFF etc with high audio quality.
what i like prefer is its drag and drop fuction and batch conversion fuction.
Here is the step by step guide at How to Convert AMR to MP3, WAV?
Hope it also helps for you.

I can't Convert midi files into any other format

A few months ago, I was able to convert midi files into mp3 when one day, I updated iTunes using software update. Ever since the updates I had for my Mac it still hasn't work.
It has this error that won't allow me to convert. I talked to my friend wrldwzrd89 who is one of my friends and he said that it is because Apple had a piece of data missing allowing midis to be converted to mp3, or any other format.
Is this true or do you know the solution?

I can't tell you the exact reason why it doesn't work, but there is an article about this problem and a solution if you have QuickTime Pro:
iTunes: MIDI files cannot be converted in iTunes 6.0.3 and 6.0.4
Not the last sentence in the article. That usually means they're working on a fix.
No guarantee that it will be fixed in the next version however. We'll have to wait and see.
Hope this helps.

Converting mp4 files to mp3 files

could someone tell me how to convert mp4 files into mp3 files? thanks

Now this is clear.
You didn't have an .mp4 file or even a .m4a file. Yours is .m4p.
The "p" stands for protected.
The rules say you can burn your .m4p files to CD. The CD file will be in .aiff format.
Drag the .aiff file into iTunes and then "convert" (using the options in your preferences for bit rate and extension).

How do I batch convert wav files to mp3?

Found this FREE easy to use mp3 converter called All2Lame, here:
http://members.home.nl/w.speek/all2lame.htm
You will also need to download LAME MP3 encoder, and copy the lame.exe & the lame_enc.dll files into the all2lame directory to get it to work:
http://www.rarewares.org/mp3-lame-bundle.php
The program offers a lot of command line type options, so you need to read the documentation to understand all your choices, but here's a 'quickstart' line you can put into the 'switches' line that will make highest quality stereo mp3's using variable bit rate technique:
--vbr-new -V 0 -q 0 --resample 44.1
If you prefer mono to save space, use this line:
--vbr-new -V 0 -q 0 -m m --resample 44.1

Converting wma's into mp3s

Hi,
I have a Zen Xtra with about a third of my files as mp3s and the rest in wma format. I've tried converting the remaining wma's into mp3s using Creatuve Media Source but it says that 'file conversion is not supported.' Even though its not necessary to turn my wma files into mp3s, I would still prefer all the files to be of the same format. Can anyone help me out? Do I need to download an update of Creative Media Source?
Appreciate any help. Thanks.

Try updating to the latest version of MediaSource, 3.30.2, from this site.
DRM stands for "digital rights management"; it's most commonly used on files downloaded from legal download services. However, some versions of WMP add DRM restrictions to ripped music, which may block certain actions. In WMP 0, choose Tools > Options, then the Rip Music tab; make sure the "Copy protect music" box is NOT checked. (It's unchecked by default in WMP 0, but was checked by default in some earlier versions of WMP.) If it is checked, uncheck it, then re-rip the CDs.

Can I turn .wma files into mp3 (or something I can use in itunes)?

iTunes for Mac can't handle WMA files, iTunes for winsloth can.
if you have access to a PC, use iTunes there to convert the files. alternatively, you can get EasyWMA and use that app.
the files need to be unprotected in both cases.

How can I turn garage band files into mp3s?

On my older Macbook i have always been able to easily turn my .band files into mp3s under the Advanced heading in itunes, but with my Macbook Pro, that is not an option. The option has become "Create AAC version". How can I turn my .band files into mp3s so that I can load them onto my web page and my students can pick them up as mp3s and put them on their devices?

The option has become "Create AAC version".
Your iTunes importing preferences are currently set to AAC. If you change your Importing preferences to mp3, the option should then become "Create mp3 version". See the following document for some more details:

You are converting the WAV files to mp3 format before transferring them to the iPod?
You're using iTunes to do this?
Just for the record, the iPod will not play mp3 files below a bit rate of 32kbps nor will it play compressed WAV files.

I need to find a way to convert .WMA files to .MP3 format on Lion

I need to find a way to convert .WMA files to .MP3 format; with Snow Leopard, I could do that using iTunes, but since upgrading to Lion, I can convert the files to a .mov format in Quick Time, but cannot move the file into iTunes in order to convert it to .MP3. If you can suggest a work-around or an app that will work with Lion, would be much appreciated.

Haven't used it myself, but worth a look http://www.macupdate.com/app/mac/27103/all2mp3

I converted aif files to mp3 files in I tunes so I could put them on a flash drive. Now when I transfer an album to the flash drive I get both the aif files and the mp3 files in the flash drive. How do I get the iTunes to only copy the smaller file?

My suggestion to use the smart playlist was more along the lines of making one list with rules to show everything in your library as long as it was kind "mpeg" (= mp3).
Smart playlists cannot be edited manually, only by changing the rules. You can use them as the basis for another smart playlist though.
There is added overhead to using smart playlists, so don't go overboard.

How to convert .doc file into .rtf file in Java?

Hello All,
I want to convert doc file into rtf format in java and for the same i am not getting any help so pls suggest some solution for that.
Thanks and Regards

MS-Word formats (DOC) are notorious for not being standardized from one version to another, so what ever you get will be version specific. If you must do the conversion, I suggest you do a MS-Script in Word to do it or one of the .Net languages. As stated the Word format from version to version is not standardized.
