I am having hard time trying to port some Java code to C# for my simple project. The Java code makes use of format.isBigEndian and checks if the audio file data is signed or not. My C# project makes use of NAudio for handling audio files.
Here is the Java code
public void LoadAudioStream(AudioInputStream inputStream) {
AudioFormat format = inputStream.getFormat();
sampleRate = (int) format.getSampleRate();
bigEndian = format.isBigEndian();
AudioFormat.Encoding encoding = format.getEncoding();
if (encoding.equals(AudioFormat.Encoding.PCM_SIGNED))
dataIsSigned = true;
else if (encoding.equals(AudioFormat.Encoding.PCM_UNSIGNED))
dataIsSigned = false;
}
and the C# code that I am working with..
public void LoadAudioStream(WaveFileReader reader)
{
var format = reader.WaveFormat;
sampleRate = format.SampleRate;
//bigEndian = ??
var encoding = format.Encoding;
if (encoding.Equals( /*????*/))
{
dataIsSigned = true;
}
else if (encoding.Equals( /*?????*/))
{
dataIsSigned = false;
}
}
How can I check if the Audio file data is big-endian or not? and lastly is there a way to check if the AudioFormat is PCM signed or unsigned ?
PCM WAV files use little endian. The most common bit depth is 16 bit, and this will be signed (ie short or Int16 in C#).
