示例1: GetSampleMinMax
private static uint GetSampleMinMax(int startSample, int sampleCount, Sound sound, int bitsPerSample, int audioChannels)
{
var bytesPerSample = (bitsPerSample >> 3) * audioChannels;
var audioByte = startSample * bytesPerSample;
var length = bytesPerSample * sampleCount;
var ptr1 = IntPtr.Zero;
var ptr2 = IntPtr.Zero;
uint refLen1 = 0;
uint refLen2 = 0;
[email protected]((uint) audioByte, (uint) length, ref ptr1, ref ptr2, ref refLen1, ref refLen2);
var destination = new byte[length];
Marshal.Copy(ptr1, destination, 0, length);
audioByte = 0;
var max = short.MinValue;
var min = short.MaxValue;
for (var currentSample = 0; currentSample < sampleCount; currentSample++) {
for (var currentAudioChannel = 0; currentAudioChannel < audioChannels; currentAudioChannel++) {
var amplitude = (bitsPerSample == 16)
? BitConverter.ToInt16(destination, audioByte + (currentAudioChannel * 2))
