AIFF files and Disc Recording

  • I'm having a tough time with a proof of concept I was asked to do.
    Part of the project is to selectively extract audio from video files
    and burn the audio to a CD. I used the sample project
    QTExtractAndConvertToAIFF to extract the audio portion out of a
    QuickTime movie. Seems to work. I can play the AIFF in the QuickTime
    Player and iTunes. So, I moved on to use the sample project AudioBurn
    to burn the converted AIFF file to a CD.

    AudioBurn won't allow me to select the output files from
    QTExtractAndConvertToAIFF so I can't burn them. I took an mp3 file
    and converted it to AIFF with iTunes. I can select that file and burn
    it to an audio CD. When I open the files with QuickTime Player the
    inspector window tells me that all the files are 16 bit, Big Endian
    41.100 khz samples. What is different about the one from iTunes and
    the others from QTExtractAndConvertToAIFF is:

    iTunes export says it's "16-bit Integer (Big Endian), Stereo, 44.100
    kHz" with a sampling rate of "1414.48 kbits/s"
    QTExtractAndConvertToAIFF says it's "16-bit Integer (Big Endian),
    Stereo (L R), 44.100 kHz" with a sampling rate of "1414.58 kbits/s"
    The QTExtractAndConvertToAIFF files are also about 6kb bigger than
    the iTunes export.

    Notice the QTExtractAndConvertToAIFF ones say "Stereo (L R)" and the
    sampling rate is slightly different.
    Every combination of settings I try with QTExtractAndConvertToAIFF
    using PCM gives me a file with the same info.

    I can't find much written up on using the AudioConverter. Can anyone
    tell me the right combination of settings to get an AIFF file
    suitable for burning on to a CD ?

    Thanks,
    Matt
  • Geez. Remember when the lists used to be a brain trust where we'd
    help each other out ? Now it's an avenue for solicitation. I asked
    for some help (see below) and I get a bright blue email with huge
    type offering Mac development service for $12/hour in India. I'll
    have to read my post again but I'm pretty sure I never asked for bids.

    This is almost as good as the head hunter who baited me with a
    project and then called the dozen or so references I gave to solicit
    business from them saying they represented me.

    So, for all you list trollers, no I am not interested in outsourcing
    my projects... ever! Don't write. Don't call. Don't send letters.

    And that conclude my rant for today.

    Thank you kindly
    Matt

  • Ironically, if they took on this project, the first thing they would
    do is come back to this list and post a similar question but with
    fewer useful details...
