Answer 1

Have you tried something like this:

AudioFileCreateWithURL //to create the output file
For each input file:
    AudioFileOpenURL //open file
    repeat
        AudioFileReadBytes //read from input file
        AudioFileWriteBytes //write to output file
    until eof(input file)
    AudioFileClose //close input file
AudioFileClose //close output file

This would probably require that the input files are all the same format and would create the output file in that same format. If you need to convert the format, that might be better done after creating the output file.
