Converting from Quicktime/Midi audio files to MP3 format

Before I upgraded to Tiger, I could use itunes to convert into mp3 form all the Quicktime Midi files that my chorus director emailed to me. Then I burned them on to cds so that everybody in the chorus could play their part in their car on the way to work and learn it really well.
Well, now when I go through the exact same steps that are on the website (go to preferences, go to advanced, change encoder to mp3, etc etc) and itunes says that it cannot convert the file to mp3 because of "unknown error (-50)."
Any ideas on how to get around this other than trashing my Tiger and going back to Panther?

I bought and downloaded quicktime Pro and used it to convert my MIDI files. First you have to find your MIDI file on your HD. Then drag it into QuickTime. Then "export" the file and in the export window select aiff as the format. Save it to your HD. Then drag the aiff file into iTunes and it will play in iTunes (6.0.4 is the version I'm using) It will also burn to a CD from within iTunes. If you only want to play the file from within iTunes, you can skip the QuickTime conversion, and simply drag and drop the MIDI file from your HD into iTunes - iTunes will play it but won't allow the file to be burnt to a CD.

  • How can I convert all of my iTunes files into mp3.format?

    These are songs that I downloaded from my cds, but I want to be able to put them back on my desktop in MP3 format to put on a non-itunes compatible portable music player. Thanks!

    Set iTunes Preferences Advanced Import to MP3
    Select all the tracks you're referring to
    CTRL-Click onto this selection - "Convert to MP3"
    After that you may want to delete the non-MP3 source files

    Probably the easiest way to do this is to download a free media convertor. Most will be able to convert video into audio files.

  • It's 2013 and I want to convert AIFF audio files to MP3s

    It’s 2013 and I want to convert .AIFF audio files to .MP3 files on my Mac.
    I created some sound files as .MOVs for a band’s website but that format doesn’t work for some Windows OS users who refuse to fetch a QuickTime plugin for their Explorer or Firefox internet browser…("don’t make them think; it either works or it doesn’t.")
    I have been told that MP3 audio files are still the most common audio files on the web and I want the band’s music to be in the most-accessible format.
    Thanks,
    Ron
    Also, this is my first Apple Support question and I would appreciate being pointed to the most appropriate forum(s).

    Thanks, Joe, that was very useful!
    For other people with my problem I should add some of the missing puzzle pieces —
    1) A while ago I loaded the songs from the band’s CD onto a previous, now dead, Mac laptop (with a previous Mac OS) and used QuickTime 7 to create down-sampled (and smaller) .mov files. Then I deleted the original .aif files from that computer.
    2) Now (back to the present) I wanted the .aif audio files on my new computer to convert them, but the computer doesn’t have a CD/DVD drive. My solution was to use my partner’s iMac.
    3) I inserted the CD into the iMac’s drive, clicked "no" to iTunes’ dialog asking if I wanted to import them, created a folder on the desktop, then opened the CD folder on the desktop and copied the songs into the newly-created folder.
    4) I copied the new .aif files to a thumbdrive then deleted the .aifs from the iMac.
    5) I put the copied thumbdrive .aif songs onto my MacBook Pro Retina (where I had changed iTunes Preferences to MP3) then I 'dropped' the sound file icons onto the iTunes icon in the dock.
    5) In iTunes I right-clicked on the songs and chose "Create MP3 Version".
    6) Next, I right-clicked on the MP3s in iTunes and chose "Show in Finder". This opened another folder (~/Music/iTunes/iTunes Media/Music/Unknown Artist/Unknown Album/), revealing the MP3s.
    7) I created duplicates of the MP3s and moved them to my band's media folder (and will put them on the website after renaming them and editing their webpage for the new audio filenames).
    8) Finally, I will delete the .aif and .mp3 songs from my iTunes, using iTunes' interface to ensure it doesn’t get confused.
    Sheesh. but I’m still happy to not have a CD/DVD drive on my MacBook Pro. I very rarely use CDs and a drive on the laptop would add bulk and weight while being mostly useless.

  • How to create QuickTime movie from JPEG and Audio file

    My Sony Cybershot allows me to record audio files for each picture. When I'm reviewing the images, I can listen to the audio. However, these files are stored separately as a JPEG and a WAV file (having identical filenames, diff extensions.
    Is there an easy way to merge these two files into a QT Movie?
    Can this be automated?
    Does anyone know of an app or script that can do this?
    Many thanks,
    Shayne

    None specific for your task that I know of.
    You'll first want to convert the silly .wav audio file (match the capture settings) to a more modern format which will also reduce its file size by a factor of ten.
    http://www.apple.com/applescript/quicktime/
    For some AppleScripts. Many no longer work with Tiger and QuickTime 7, however.
    It may take some time but if you have hundreds to make it (Automator) can help speed up your workflow.

  • Trouble converting downloaded m4a files to mp3 format

    This has never happened to me before. I downloaded a full album and 3 of the 13 songs get an error saying "the file format is not valid" when I try to convert the files to mp3 format. How do I go about fixing this?

    +if I do that, it will create the MP3 files all in the same iTunes Music folder as the AAC files,+
    Yes, if the AACs are by artist/album
    +and worse, it will probably duplicate each song in the playlist.+
    No, the conversion process does not touch any playlists.
    +The only thing I can think of is to either (A) have a blowaway copy of iTunes on the Windows PC, copy all the AAC files to it, import them, and convert them, or (B) allow my real iTunes to duplicate them all, make the MP3 CDs, sort by create date or file type, and delete the MP3 duplicates from the library.+
    B sounds easier than A. You can also consider doing the conversions with a non-iTunes program such as Switch, which allows you to specify the destination folder for the new file.

  • Does anyone know a good converter from quicktime movies to dvd format?

    Does anyone know a good converter from quicktime movies to dvd format?

    I'm guessing that your using One Step DVD . This will only work with one movie at a time.
    Create a new project and all you should have to do is drag your movies from your movie folder onto your iDVD project. You can add as many movies as you like but obviously you can't exceed the maximum total DVD size.
    Encoding can take a long time depending on the original file format, but you should be able to use pretty much any file format you can play with Quicktime.

  • How get one channel of data from two-channel audio file?

    I need to either convert a 2-channel audio file to 1-channel or else get just one channel of data (does this lose some sound?) for a calculation. How would I do that?

    In terms of a loop over byte[] data, double[] left, double[] right...
    8-bit mono
    for (int i = 0; i < data.length; i += 1) {
         left[i] = (double)data;
    16-bit monofor (int i = 0; (i*2) < data.length; i++) {
    left[i] = ((double)data[2*i] << 8) + (double)data[(2*i)+1]);
    8-bit stereofor (int i = 0; (i*2) < data.length; i++) {
    left[i] = (double)data[2*i];
    right[i] = (double)data[(2*i)+1];
    16-bit stereofor (int i = 0; (i*4) < data.length; i++) {
    left[i] = ((double)data[2*i] << 8) + (double)data[(2*i)+1]);
    right[i] = ((double)data[(2*i)+2] << 8) + (double)data[(2*i)+3]);

  • Convert REM Files to MP3 Format?

    I have downloaded several songs via the Amazon MP3 application on my Blackberry Curve 9300.  Little did I know that the songs were downloaded as rem files and not mp3 format?  I cannot upload the files to my desktop or laptop computers nor my Kindle. 
    Amazon said since I downloaded most of the songs over 3 months ago, they cannot move them over to my Cloud Player.  How do I convert rem file to mp3 format?  I do not want to have to purchase these songs again.

    That process above won't work. Waste of time.
    Your files were downloaded as MP3 files, but you have content encryption placed on your Media Card, and then the REM extension is added to the filename, because you have protected those files.
    You must turn off the encryption first, and then you can copy the files and they will be usable.

  • Converting .wav files to mp3 format.

    Hi,
            I am trying to convert a wav file into mp3 format using the below code. I am not seeing any errors in the console but at the same time the mp3 file is created without any content. Any ideas on how to address this issue ?

    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.

  • Ideas for making CD from one long audio file

    Hi. Any angels out there willing to suggest the easiest way to make a CD of songs from one long audio file? I'm a teacher and recorded my little 4 year old students singing all their favorite songs. Now I want to turn it into a CD for parents. Should I create new files for every song, cut and paste that part of the audio file into its own song file, save, then throw them all into wave burner? Seems laborious but can't figure another way. Thanks if you've got an idea!

    I've only used WB once, so I THINK this is the way to do it:
    Import the whole single track into WB, and use the scissor tool to cut the file where you want the new track to begin. Wherever you cut WB will make a new track. Then you can tweak the beginning and end of tracks, or do fades accordingly. When you burn it will create a CD with these tracks.

  • 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

  • HT3775 How can I play an audio file in 3GP format?

    Is that file played in a tab in the current window or in a separate pop-up window?
    Are you allowing pop-up to modify the window size (dom.disable_window_move_resize = false)?
