This article mainly introduces the relevant knowledge of "how to use DirectX.DirectSound to play voice in C#". The editor shows you the operation process through an actual case. The operation method is simple, fast and practical. I hope this article "how to play voice with DirectX.DirectSound in C#" can help you solve the problem.

Characteristics of DirectX.DirectSound

1. Multiple voice messages can be played at the same time

2. Can be divided into left and right channels for playback.

3. The voice being played can be released at any time.

This component handles the flow:

1. Create a playback thread

Public void StartDirectXSoundThread (Control _ con) {IsStart = true; if (control = = null) control = _ con; Task task = new Task (() = > {while (true) {try {if (! IsStart) break If (! IsPlaying ()) {if (soundlist.Count > 0) {if (! IsPlayVoice) {IsPlayVoice = true Control.Invoke ((MethodInvoker) delegate {SoundPlay (soundlist [0]); soundlist.RemoveAt (0);}) } catch (Exception ex) {LogHelper.Debug (ex) } finally {} Thread.Sleep;}}); task.Start ();}

2. Release the playback thread

Public void StopDirectXSoundThread () {IsStart = false;}

3. Determine whether to play or not. Judge whether or not to play by the conditions of PlayPositionplayback null 0 and playback buffer.

Private bool IsPlaying () {bool Ret = false Try {if (IsCreate) {if (secBuffer! = null) {if (secBuffer.PlayPosition! = 0) {Ret = true } catch (Exception ex) {LogHelper.Debug (ex);} return Ret;}

4. Play audio

Public void SoundPlay (string _ wavpath) {try {if (_ wavpath.IndexOf ("\\")

< 0) { _wavpath = SoundPath + _wavpath; } if (_wavpath.IndexOf(".wav") < 0) { _wavpath += ".wav"; } if (!File.Exists(_wavpath)) { LogHelper.Info("无" + _wavpath + "文件！"); } else { secDev.SetCooperativeLevel(control, CooperativeLevel.Normal); BufferDescription buffdes = new BufferDescription() { GlobalFocus = true }; secBuffer = new SecondaryBuffer(_wavpath, buffdes, secDev); secBuffer.Play(0, BufferPlayFlags.Default);//设置缓冲区为默认播放 } IsCreate = true; IsPlayVoice = false; } catch (Exception ex) { LogHelper.Debug(ex); }} 左右声道通过secBuffer.Pan属性进行控制，值含义见下图： a、Center中心通道，左右通道同时播放，默认值0 b、Right右通道，值10000 c、Right左通道，值-10000

5. Clear the playing audio, and the playing audio can be released by the Dispose () method.

Public void ClearPlay () {if (secBuffer! = null) {soundlist.Clear (); secBuffer.Dispose (); IsCreate = false;}}
