A simple application that shows how to play and record sounds under Windows

Introduction

This is a simple application that shows you how to play and record sound under windows.
It uses the old multimedia API. A better solution may be to use DirectSound.

Quick Guide to the Code

Start with the two functions in CFisterDlg called OnPlay and OnRecord. Follow them down to the depth you need to use the classes.

Short description

CSoundIn is a wrapper class that will let you retreive sound from the soundcard. The main functions are Start() and Stop()

CSoundOut is a wrapper class that will let you play sound on the soundcard. The main functions are Start() and Stop()

CSoundFile is a wrapper class of a single wave file, it can either be a file reader or a file writer object. See the constructor.

CSoundBase is a very small class that encapsulates the wave format.

CBuffer is a very small class that encapsulates a simple one dimentional buffer.

The project has a number of different callback functions:

  • One callback function makes the Play button change it's label to stop when it has finished playing the file. CDialogDlg enherits
    CPipe 
    and overloads a function that CPipe can call when it has finished playing the wave file.
  • Another callback function make it possible for CSoundIn to callback to CPipe when it has filled the input buffer. Thus CPipe can give CSoundIn a new buffer to fill.
  • A clone of the above principle is also used in CSoundOut, which enables it to callback to the owner when it is finished playing the sound in a given buffer.

Problems that I encountered

I have spent almost 2 days debugging the following stupid problem. When CSoundIn and CSoundOut inherit from CSoundBase and CWinThread the order in which they are listed must be as shown below. If not, the callback functions, which are started by the WinThread message handler, will not be able to access the member variables of the CSoundIn object.

class CSoundIn : public CWinThread, public CSoundBase

During these two days of fustration I also tried to implement the callback as regular callback functions called by the device driver. This is possible using ::waveInOpen(...). But since this callback function is not allowed to call any of the ::waveInXXX(...) functions it is not of much use.
