Tony,
You probably should write an application instead of a plug in (AU). Since you are specifically reading files and producing text, you might just use CoreAudio features like AudioFile and ExtAudioFile to read your audio files, and then do all of the rest of the processing in your application. If you are not going to listen to the audio while this process is happening, then you don't need an AU. Also, you're not going to find any AudioUnit hosts that deal with a plugin that only accepts files and only produces a numerical text report.
There are a lot of features in CoreAudio besides AudioUnits, and most of them are available to any application.

Please forgive me f I asked a stupid question. I am new to write an AU.
I am expecting to build an AU for detecting beats from audio files. I
want it to be able to output a text files which would list the time
points when the beats has been detected. Recording to the
documentation, the output from an AU could be audio stream or midi
effect, but it never mentions a text file. I am thinking of calling
standard C++ library function within the AU to generate the text files
as output instead of an audio stream. Is this possible to do it?
many thanks .
Tony
