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...

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

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 ?
