I am having problems debugging the code in
http://www.sonicamigos.com/etejkowski/code.html
for windows since i do not have a log of what the values look like for
a particular wave file. If anyone sees the sample.mov under their
quicktime directory could someone run the code on a mac, log the
values and send them to me please?
I hope I am not asking too much,
the log function that is not there and that you probably will need to
add under the Log method is
'Log s
// This method logs a string into the debug.txt file
Dim file As FolderItem
Dim fileStream As TextOutputStream
file= GetFolderItem("debug.log")
if file.Exists then
fileStream=file.AppendToTextFile
else
fileStream=file.CreateTextFile
End if
fileStream.WriteLine s
fileStream.Close
thanks for your help, if you choose to use any other wave file or
movie please let me know which and send it to me too,
Many thanks,
luis
