关于MCI_RECORD一问

msblaster 2003-09-11 07:23:53

我用
{
MCI_OPEN_PARMS mciOpenParms;
MCI_RECORD_PARMS mciRecordParms;
// Open a waveform-audio device with a new file for recording.
mciOpenParms.lpstrDeviceType = "waveaudio";
mciOpenParms.lpstrElementName = "";
mciSendCommand(0, MCI_OPEN, MCI_OPEN_ELEMENT |I_OPEN_TYPE, (DWORD)(LPVOID)
&mciOpenParms);
UINT wDeviceID = mciOpenParms.wDeviceID;
mciRecordParms.dwTo = 1000;
mciSendCommand(wDeviceID, MCI_RECORD, MCI_TO | MCI_WAIT, (DWORD)(LPVOID) &
mciRecordParms);
}
录制一段wave，但是如何得到记录wave的buffer指针？
我想把wave的内容直接send到internet，希望高人指点。

VC实现录音,放音,保存,打开功能，很详细的说明。

MCI GONG NENG,支持VB，使用MCI功能，另外提供API播放

MCI音频播放，停止，录音程序，实现程序对多媒体设备的直接控制

MCI的应用示例，包括播放WAV、MIDI文件和播放CD及将CD中的曲目转录为WAV文件等

一款很不错的录音程序，附带源代码，自行编译：如遇到内存不能读写错误（103行），请把编译 CPU Type 从“Any CPU”改为“x86”即可。部分代码： public const string WaveAudio = "waveaudio"; public const uint MM_MCINOTIFY = 0x3B9; public const uint MCI_NOTIFY_SUCCESSFUL = 0x0001; public const uint MCI_NOTIFY_SUPERSEDED = 0x0002; public const uint MCI_NOTIFY_ABORTED = 0x0004; public const uint MCI_NOTIFY_FAILURE = 0x0008; public const uint MCI_OPEN = 0x0803; public const uint MCI_CLOSE = 0x0804; public const uint MCI_PLAY = 0x0806; public const uint MCI_SEEK = 0x0807; public const uint MCI_STOP = 0x0808; public const uint MCI_PAUSE = 0x0809; public const uint MCI_RECORD = 0x080F; public const uint MCI_RESUME = 0x0855; public const uint MCI_SAVE = 0x0813; public const uint MCI_LOAD = 0x0850; public const uint MCI_STATUS = 0x0814; public const uint MCI_SAVE_FILE = 0x00000100; public const uint MCI_OPEN_ELEMENT = 0x00000200; public const uint MCI_OPEN_TYPE = 0x00002000; public const uint MCI_LOAD_FILE = 0x00000100; public const uint MCI_STATUS_POSITION = 0x00000002; public const uint MCI_STATUS_LENGTH = 0x00000001; public const uint MCI_STATUS_ITEM = 0x00000100; public const uint MCI_NOTIFY = 0x00000001; public const uint MCI_WAIT = 0x00000002; public const uint MCI_FROM = 0x00000004; public const uint MCI_TO = 0x00000008; // Structures [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)] public struct MCI_OPEN_PARMS { public IntPtr dwCallback; public uint wDeviceID; public IntPtr lpstrDeviceType; public IntPtr lpstrElementName; public IntPtr lpstrAlias; } [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)] public struct MCI_RECORD_PARMS { public IntPtr dwCallback; public uint dwFrom; public uint dwTo; } [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)] public struct MCI_PLAY_PARMS { public IntPtr dwCallback; public uint dwFrom; public uint dwTo; } [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)] public struct MCI_GENERIC_PARMS { public IntPtr dwCallback; } [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)] public struct MCI_SEEK_PARMS { public IntPtr dwCallback; public uint dwTo; } [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)] public struct MCI_SAVE_PARMS { public IntPtr dwCallback; public IntPtr lpfilename; } [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)] public struct MCI_STATUS_PARMS { public IntPtr dwCallback; public uint dwReturn; public uint dwItem; public uint dwTrack; } ; // Functions [DllImport("winmm.dll", CharSet = CharSet.Ansi, BestFitMapping = true, ThrowOnUnmappableChar = true)] [return: MarshalAs(UnmanagedType.U4)] public static extern uint mciSendCommand( uint mciId, uint uMsg, uint dwParam1, IntPtr dwParam2); [DllImport("winmm.dll", CharSet = CharSet.Ansi, BestFitMapping = true, ThrowOnUnmappableChar = true)] [return: MarshalAs(UnmanagedType.Bool)] public static extern bool mciGetErrorString( uint mcierr, [MarshalAs(UnmanagedType.LPStr)] System.Text.StringBuilder pszText, uint cchText); } }
