public class UlawFormatConversionProvider

extends TEncodingFormatConversionProvider

This provider (currently) supports these conversions:

• PCM 8 Signed -> ulaw
• PCM 8 Unsigned -> ulaw
• PCM 16 signed big endian -> ulaw
• PCM 16 signed little endian -> ulaw
• alaw -> ulaw

and vice versa.

FrameRate, SampleRate, Channels CANNOT be converted.
