Introduction

At first time,this is update.This project introduces how to use waveInopen and waveOutopen to recording and play the waveform audio.This is MFC application using VC++.The purpose is to help to understand waveform audio function,so that i don't build completely a program recording.

What will you find in my demo:

1. I use C to write some function:

    DoRecord(): to begin record.

    DoRecord_end(): to end record

    DoPlay(): to play the recording voice.

2. In function DoRecord():

    I show you how to use WaveInOpen with CALLBACK_FUNCTION waveInproc. I also show you how to use waveInPrepareHeader,waveInAddBuffer and waveInStart to begin recording your voice.Specially, i introduce how to use waveInproc.

3. In fucntion DoPlay():

    I show you how to use WaveOutOpen,waveOutPrepareHeader,waveOutWrite.

Demo:

  1) Click Record to begin recording your voice.

  2) Click Record_end when you finish your recording.

  3) Click Play to hear your voice.

Future: 

  I will add some function to allow to save your recording to a file wav. And some other function to allow to choose the format of wave audio.

  I will show some other technique to use CALLBACK like CALLBACK_EVENT,CALLBACK_WINDOW or CALLBACK_THREAD to process the voice recording.

  I will add some other function socket or rtp so you can transfer your recording or to voice chat with other.
