Convert audio files from 256kbps tot 1411kbps

I would like to know if i gain any extra music quality (depth, clarity etc.) by converting my music files in Itunes from 256kbps to 1411kbps (WAV)
Apple Lossless format seems to be good to.
I read somewhere that converting in Itunes from 256kbps to a higher kbps format only adds extra bites. The extra quality isn't there however...
Has anyone got an opinion about this stuff?
Greetings Harry (Holland)

No, you don't. The music needs to be originally imported at the higher bitrate to get the benefit of it; this isn't possible for iTunes Store music.

Converting audio file from one format to another format

Hi Friends,
Is it possible to convert the audio file from one format to another format(*.mp3 to *.wav file and vice versa)?
If so, please guide me on the same.
Thanks in advance,
Kavitha Anbazhagan

It's been covered here already, but take a look here:
Converting CDs to iTunes Audiobooks
Just read the parts after the section on importing from CD.

How can I convert audio files from Windows Media player to WMV?

I am unable to add a soundtrack if it is a WMA file. What programs are best to convert files to WMV?

If you are wishing to add the WMA soundtrack to a PrE Project, I would convert/rip the WMA to PCM/WAV 48KHz 16-bit, and then Import that WAV file into the PrE Project. Drag it to a free Audio Track. Though there is a Soundtrack Track, some users have had issues with it. Any free Audio Track, with the necessary channel-count is likely to work better.
For the conversion/ripping, there are many programs that can do this for you. I use Adobe Audition, but the great, free Audacity can do it nicely, as well.
As WMA can have aspets, like 6-channel Audio, wrapped in the WMA, I like doing the conversion, unless I need, say the 6 discrete channels in Audition, for output to DTS Audio with the SurCode DTS encoder program.
Good luck,
Hunt

How do I convert a .wma Audio file from a pc to .mp3 for itunes on a mac

I downloaded music from my PC laptop into an external drive. When I connected the external drive to the mac, the .wma Audio files from the PC will not transfer to iTunes on the Mac.
Thanks for any help.

iTunes on the PC will convert wma. iTunes on a Mac won't.
On your PC, add the wma files to iTunes.
iTunes will convert to whatever you have set in iTunes prefs > General - Import settings.
Then copy the imported files to the external then File > Add to library on the Mac.

Playing an audio file from applet

Hi friends,
I have a problem to be solved .
Please help me.
I have to play an audio file from applet.When the applet loads it shold start playing .There is a progress bar in the applet it shold alsomove corresponding to that.
How can i do that.Give me an idea.
I know nothing about jmf.
I am using j2sdk1.4,windows 2000 server.

Andrew,
Forgive my naivety, but i struggle with JAVA! I am desperately trying to create a JAVA plugin to SERVOY and have to date been successful with a few things. Record, Playback, convert to .spx.
I am really struggling with implementing a rewind and fastforward function of the type you have. I thought it would be easy, but it appears not.
At the bottom is the complete code from my class that is called by the servoy plugin wrapper,
i had thought that adding some simple jump 500 ms would have been easy in something like this:
public AudioStream js_FastForward (AudioStream as) throws IOException {
!!! Line or two here to move the play head forward !!!
     AudioPlayer.player.start(as);
     return as;
Can you give me any pointers to how i code that fast forward bit.
many thanks
David

How-To: Convert audio files to the desired Cisco format (SoX example)

Greetings,
This week I spent a few hours on converting PCM encoded wave files to CCITT ulaw encoded wave files. You know, the format we all use for UCCX, IP IVR and the like.
I have been searching the interwebs and came across a few suggestions, amongst others:
o Adobe Audition
o Audacity
I installed Audition Cs5.5 on my Mac, but it wouldn't let me export CCITT ulaw files.
I also installed Audacity, which would let me export files in the right format, but doesn't support batch conversion of audio files. When you're moving from one voice application to another, this is a huge drawback. For occasional conversion, I would recommend this (graphical) tool.
The solution I have used is the open source software SoX (Sound eXchange) which can be found here: http://sox.sourceforge.net/
It is a cross-platform (Win, Linux, Mac) command line utility that can be use to convert audio files, concatenate them and what not. I just this in conjunction with a perl script I made.
The script is attached, in the hope someone else benefits from it. Should work out of the box on Mac and Linux machines. The script will traverse the $dirname directory (not recursively) and convert what it finds to 8bit, 8kHz, mono, CCITT ulaw format.
By the way, to concatenate files just simply type:
sox half1.wav half2.wav full.wav
This will concatenate half1.wav and half2.wav and name the resulting file full.wav.
HTH
P.s: Disclaimer: You might need to edit the script. There is no implied fitness for a particular purpose, YMMV and I shall not be liable for messed up audio files or what not.
Edit: url added.

Hi,
welcome to the beautiful world of open source :-) By the way, I have not seen anybody programming in Perl for a long time.
Just one comment: G.711 uLaw is just the half of the story. Remember, UCCX supports either G.711 uLaw or G.729 as well. And since G.729 has license restrictions (costs $10000 per year if I remember that correctly), no free software can incorporate it to its "convert to" list (apart from reading it, which is fine).
A piece of advice: CUCM has got that voice translator service running, which does the job as well. All you have to do is to upload your files, and you'll get at least four formats ready and available, including G.729 - and it can be downloaded easily using TFTP later and used in UCCX.

How do I move MPEG audio files from my iPod to my library on my computer???

Can someone tell me how to move MPEG audio files from my iPod to my library on my computer? Somehow all my songs on my iPod are MPEGs and they won't transfer to the library. I really don't want to loose the music, and there doesn't appear to be an option to convert the MPEG to a ACC file while the MPEG is on the iPod. Please help....

iTunes/iPod does not provide a way of copying tracks from an iPod to iTunes except for purchased music. But iTunes can play MP3 files without conversion.
Here are some ways of getting files from an iPod to your PC:
Copy from iPod to PC
It is important not to allow your iPod to sync with an empty library. If it is set to synchronise automatically you will get a message saying your iPod is linked to a different library and asking if you want to sync – it is important to press cancel as syncing with an empty library erases all music from your iPod.
You can also prevent auto sync by holding down shift & ctrl as you plug in your iPod and keeping the keys held down until the iPod appears in iTunes.
Once you are connected, you need to set your iPod to manage music manually.
http://support.apple.com/kb/HT1535
If you have an iPod with iTunes Store purchases on it, you can use it to copy your purchases to other authorized computers.
http://support.apple.com/kb/HT1848
However this is not allowed for other music.
This MacMuse tip tells you how to copy music from your iPod using Windows Explorer, but it is a bit fiddly:

Otherwise you can use third party software to manage the transfer, there are a variety of programs out there, some free and some that will copy ratings and counts as well as the music files. Here is a selection, check them out and see what suits you.

Need to export an AC3 audio file from FCP

Does anyone know how to export (or convert to) and AC3 audio file from FCP? My compressor is not currently working, is there another way? I have Sorenson Squeeze and FCP 5.0.4. Thank you!!!
alex

Upload your audio file to my Public folder and wait 20 mins. I'll compress the audio to .ac3 for you if you're in a crunch. Check back in my Public Folder and I'll have it there for you.

Batch Extract Audio Files from .m4a videos

I saw something about using Terminal to extract audio files from a batch of quicktime movies, but I'm not sure where it was. Anyway, is there a way besides doing each manually? There are quite a few of them. I know my way around Terminal fairly well if necessary.

Okay, I kind of solved it (drag and drop, click, drag and drop, click, etc...) by using ffmpegX, which puts each file into a queue and goes through and converts them all. Still, it would be cool if there was a way to do it all in a single batch because if you drop a batch into ffmpegX, it only does the first one.

how can i convert video files from my mac to watch them on my iphone?, how can i convert video files to watch them on my iphone?

Turns out the answer to that question changes if you ask it more than 4 times, so ask it again....
The answer depends on the type of video files you want to convert. If they are DRM protected commercial videos, no help can be given here. Google.

iTunes/iPod does not provide a way of copying tracks from an iPod to iTunes except for purchased music. But iTunes can play MP3 files without conversion.
Here are some ways of getting files from an iPod to your PC:
Copy from iPod to PC
It is important not to allow your iPod to sync with an empty library. If it is set to synchronise automatically you will get a message saying your iPod is linked to a different library and asking if you want to sync – it is important to press cancel as syncing with an empty library erases all music from your iPod.
You can also prevent auto sync by holding down shift & ctrl as you plug in your iPod and keeping the keys held down until the iPod appears in iTunes.
Once you are connected, you need to set your iPod to manage music manually.

If you have an iPod with iTunes Store purchases on it, you can use it to copy your purchases to other authorized computers.

However this is not allowed for other music.

When I converted a file from PDF to WORD.DOC it opened as Read Only and I'm unable to alter any of the text. How can I solve this problem?

When I tried to convert a file from PDF to WORD.DOC it opened as Read Only and I'm unable to alter any of the text. How do I solve this problem? I don't know how to change it from Read Only.

Dear Sara
Thank you very much for sending the converted file. Yes, I am able to edit it - that will be very useful to me and I appreciate your help.
Referring to your previous message when you said you'd converted via Acrobat and not Acrobat.com, I'm converting via Acrobat.com because that's the only option that is shown (how do I convert via Acrobat? - perhaps that would be more successful). I'm using the Export PDF website, and the OCR is enabled to "Recognize text in English UK". However, I've just tried converting a different LPA pdf form, this time for Health & Welfare https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/245571/LPA114_He alth_welfare_LPA.pdf and again I have the same problem as before. I've altered it from "Read only" and thought I'd then be able to enter text, but "Drawing Tools" is shown in the pane and I'm unable to enter anything onto the form - everything appears to be in images. Also, the lettering on the heading of' page 1 has become jumbled, with the word "Public" overlaying the word "Guardian." Any suggestions as to what it is I'm doing wrong would be welcome - I don't like to be beaten!
Regards,
Judith.

HT1473 how do i save an audio file from a webpage to iTunes?

how do i save an audio file from a webpage to iTunes?

If the web page is designed to let you save files it will often have a download link, or if it is a link to the file directly you can try to right click on the file. If it isn't set up that way then they probably don't intend for the file to be downloaded.
