C# mci SoundRecord录音

概述C# mci SoundRecord / 录音

下面是内存溢出 jb51.cc 通过网络收集整理的代码片段。

内存溢出小编现在分享给大家，也给大家做个参考。

        private SoundRecord m_Record = new SoundRecord();        private voID MainForm_Load(object sender,EventArgs e)        {                 this.m_Record.OpenRecord(); // 打开录音            this.m_Record.StartRecord(); // 开始录音        }        private voID BtnStopAndSave_Click(object sender,EventArgs e)        {                       this.m_Record.StopRecord(); // 停止录音            this.m_Record.SaveRecord(@"C:\Users\windo\Desktop.wav"); // 保存录音            this.m_Record.CloseRecord(); // 关闭录音        }

上面的代码只是一个简单的录音并保存的过程，不过该类本身就很简单 而且我也附

    public partial class SoundRecord    {        [Dllimport("WinMm.dll",CharSet = CharSet.auto,CallingConvention = CallingConvention.Cdecl)]        private static extern int mciSendString(string lpstrCommand,string lpstrReturnString,int uReturnLength,int hwndCallback);              private const int ERROR_SUCCESS = 0;        private const string MODE_UNKNowN = "unkNown";        private static bool mciSendString(string strCommand)        {            return mciSendString(strCommand,null,0) != ERROR_SUCCESS;        }    }    public partial class SoundRecord    {        private int m_channels;             private int m_sample_spersec;        private string m_format_tag;        private int m_bits_per_sample;        public SoundRecord()        {            this.Channels = 2;            this.FormatTag = "pcm";            this.BitsPerSample = 8;                      this.SampleSpersec = 11025;               }        // 采样位数        public virtual int BitsPerSample        {            set            {                if (mciSendString("set wave bitpersample " + value))                    this.m_bits_per_sample = value;            }            get            {                return this.m_bits_per_sample;            }        }        // 采样频率        public virtual int SampleSpersec        {            get            {                return this.m_sample_spersec;            }            set            {                if (mciSendString("set wave samplespersec " + value))                    this.m_sample_spersec = value;            }        }        // 声道        public virtual int Channels        {            get            {                return m_channels;            }            set            {                if (mciSendString("set wave channels " + value))                    this.m_channels = value;            }        }        // 格式标签        public virtual string FormatTag        {            get            {                return this.m_format_tag;            }            set            {                if (mciSendString("set wave format tag " + value))                    this.m_format_tag = value;            }        }        // 打开录音        public virtual bool OpenRecord()        {            return mciSendString("open new type waveaudio alias movIE");        }        // 开始录音        public virtual bool StartRecord()        {            return mciSendString("record movIE");        }        // 停止录音        public virtual bool StopRecord()        {            return mciSendString("stop movIE");        }        // 保存录音        public virtual bool SaveRecord(string savefilename)        {            return mciSendString("save movIE " + savefilename);        }        // 关闭录音        public virtual bool CloseRecord()        {            return mciSendString("close movIE");        }        // 暂停录音        public virtual bool PauseRecord()        {            return mciSendString("pause movIE");        }        // 恢复录音        public virtual bool ResumeRecord()        {            return mciSendString("resume movIE");        }        // 执行状态        public virtual string Status        {            get            {                string strBuffer = new string('',12);                if (mciSendString("status movIE mode",strBuffer,12,0) != ERROR_SUCCESS)                    return MODE_UNKNowN;                if ((strBuffer = strBuffer.Remove(strBuffer.IndexOf(''))).Length <= 0)                    return MODE_UNKNowN;                return strBuffer;            }        }    }
