RemarksCode is mainly based on information available on the original C source code pa_converters.c from Portable Audio I/O Library.
This class try to be as fast as possible without using unsafe code.
Dither isn't currently supported. Currently supported conversions are 'to' and 'from' conversions between the following most common PCM format:
- Integer 8-bit (byte)
- Integer 16-bit (Int16)
- Integer 32-bit (Int32)
- Single precision 32-bit floating point (float)
Examples
To use it, just call Convert. The compiler will automatically detect
which method to call based on your data types.
// Suppose we have a collection of samples in PCM-16 format // and wish to convert it into IEEE-32 floating point format: int[] pcm16Samples = new int [3] { 1, 2, 3 }; // source float[] floatSamples = new float[3]; // target // Call convert passing the source samples. Converted // IEEE samples in will be stored in the target array. SampleConverter.Convert(pcm16samples, floatSamples);
