Super class PortAudioStreamBaseMBS

Flags

Constant Value Description
kFlagsClipOff 1 Disable default clipping of out of range samples.
kFlagsDitherOff 2 Disable default dithering.
kFlagsNeverDropInput 4 Flag requests that where possible a full duplex stream will not discard overflowed input samples without calling the stream callback. This flag is only valid for full duplex callback streams and only when used in combination with the paFramesPerBufferUnspecified (0) framesPerBuffer parameter. Using this flag incorrectly results in a paInvalidFlag error being returned from OpenStream and OpenDefaultStream.
kFlagsNoFlag 0 No flags.
kFlagsPlatformSpecificFlags &hFFFF0000 A mask specifying the platform specific bits.
kFlagsPrimeOutputBuffersUsingStreamCallback 8 Call the stream callback to fill initial output buffers, rather than the default behavior of priming the buffers with zeros (silence). This flag has no effect for input-only and blocking read/write streams.

This class has no sub classes.
