Audio Player Demo with Dynamic Crosshairs

How to associate callback functions to audioplayer object?

Description

Introduction:

This package encloses a small application dedicated to speech signal processing
at 8 kHz or 16 kHz. This application reads standard *.wav or *.pcm files through
UI dialog box, plots and plays the signal with vertical dynamic crosshairs.

This application illustrate how to associate callback functions with audio player
object like dynamic crosshairs and how to pass parameters to these functions.

It could be used as a basis for more sophisticated graphical user interface (GUI)
dedicated to speech processing.

• MATLAB release: MATLAB 7.4 (R2007a)
• Other requirements: PC with loudspeakers

I'm using just the 'f_update_crosshairs_x' function but it helped me a lot.

Unfortunately, it does not work on my mac.
