SplitChannels(Stream, WavAudioInfo, Nullable<TimeSpan>)

Get samples per channel. The first channel (mono if it is the only channel) is usually the left.

Declaration

public static double[][] SplitChannels(this Stream wavSource, WavAudioInfo wavInfo, TimeSpan? duration)

Parameters

Type	Name	Description
Stream	wavSource	The wav Source.
WavAudioInfo	wavInfo	The wav Info.
Nullable<TimeSpan>	duration	The duration.

StreamCopy(Stream, Stream)

Copy one stream to another.

Declaration

public static void StreamCopy(this Stream source, Stream target)

Parameters

Type	Name	Description
Stream	source	The source.
Stream	target	The target.

Examples

using (FileStream iFile = new FileStream(...))
using (FileStream oFile = new FileStream(...))
using (DeflateStream oZip = new DeflateStream(outFile, CompressionMode.Compress))
StreamCopy(iFile, oZip);

Depending on what you are actually trying to do, you'd chain the streams differently. This also uses relatively little memory, because only the data being operated upon is in memory.
