Subject:ReadAudio Posted by: des griffiths Date:11/20/2006 5:54:57 AM There seems to be an issue with ReadAudio. Take these two cases: // Case 1 float[] sampleDataL = new float[ 20 ]; file.ReadAudio( sampleDataL, 0, 1, SfSampleType.Unknown ); float[] sampleDataR = new float[ 20 ]; file.ReadAudio( sampleDataR, 0, 2, SfSampleType.Unknown ); // Case 2 float[,] sampleData = new float[ 2, 20 ]; file.ReadAudio( sampleData, 0 ); The second case seems to work fine, however the first case works only for the left channel; the right channel read starts reading data into sampleDataR[1] instead of sampleDataR[0]. This can be more easily seen when the first sample value of the right channel of the input file is not 0 to begin with. (Note: this is true when the input file is 16-bit - I haven't tried any other bit-depths). Richard.

There seems to be an issue with ReadAudio. Take these two cases:

// Case 1
float[] sampleDataL = new float[ 20 ];
file.ReadAudio( sampleDataL, 0, 1, SfSampleType.Unknown );
float[] sampleDataR = new float[ 20 ];
file.ReadAudio( sampleDataR, 0, 2, SfSampleType.Unknown );

// Case 2
float[,] sampleData = new float[ 2, 20 ];
file.ReadAudio( sampleData, 0 );

The second case seems to work fine, however the first case works only for the left channel; the right channel read starts reading data into sampleDataR[1] instead of sampleDataR[0]. This can be more easily seen when the first sample value of the right channel of the input file is not 0 to begin with.
