如何剪切mp3文件的某个时间并将其转换为N音频的波形而不在硬盘中保存任何文件? (我想要
byte array
的结果!)
参考以下代码:
string nMP3Folder = "FOLDER PATH";
string nMP3SourceFilename = "SOURCE MP3 FILENAME";
string nMP3OutputFilename = "YOUR OUTPUT MP3 FILENAME";
using (Mp3FileReader rdr = new Mp3FileReader(nMP3Folder + nMP3SourceFilename))
{
int count = 1;
Mp3Frame objmp3Frame = reader.ReadNextFrame();
System.IO.FileStream _fs = new System.IO.FileStream(nMP3Folder + nMP3OutputFilename, System.IO.FileMode.Create, System.IO.FileAccess.Write);
while (objmp3Frame != null)
{
if (count > 500) //retrieve a sample of 500 frames
return;
_fs.Write(objmp3Frame.RawData, 0, objmp3Frame.RawData.Length);
count = count + 1;
objmp3Frame = rdr.ReadNextFrame();
}
_fs.Close();
}
