Write uses the buffer provided to OpenStream. The number of samples to write is determined by the size of the buffer.

Close terminates the stream.

Read uses the buffer provided to OpenStream. The number of samples to read is determined by the size of the buffer.

Initialize initializes internal data structures and prepares underlying host APIs for use. With the exception of Version(), VersionText(), and ErrorTe

Terminate deallocates all resources allocated by PortAudio since it was initialized by a call to Initialize(). In cases where Initialize() has been c

Start commences audio processing.

Stop terminates audio processing. It waits until all pending audio buffers have been played before it returns.

OpenDefaultStream is a simplified version of OpenStream that opens the default input and/or output devices. The args parameter has the same meaning a

HostApis returns all information available for HostApis.

OpenStream creates an instance of a Stream. For an input- or output-only stream, p.Output.Device or p.Input.Device must be nil, respectively. The ar

DefaultHostApi returns information of the default HostApi available on the system. The default host API will be the lowest common denominator host AP

Devices returns information for all available devices on the system.

HighLatencyParameters are mono in, stereo out (if supported), high latency, the smaller of the default sample rates of the two devices, and FramesPerB

DefaultInputDevice returns information for the default input device on the system.

DefaultOutputDevice returns information for the default output device on the system.

LowLatencyParameters are mono in, stereo out (if supported), low latency, the larger of the default sample rates of the two devices, and FramesPerBuff

export streamCallback

Abort terminates audio processing immediately without waiting for pending buffers to complete.

AvailableToRead returns the number of frames that can be read from the stream without waiting.

AvailableToWrite returns the number of frames that can be written from the stream without waiting.

CpuLoad returns the CPU usage information for the specified stream, where 0.0 is 0% usage and 1.0 is 100% usage. The "CPU Load" is a fraction of tota

HostApi returns information for a requested HostApiType.

Info returns information about the Stream instance.

IsFormatSupported Returns nil if the format is supported, otherwise an error. The args parameter has the same meaning as in OpenStream.

PutInt32 puts the three most significant bytes of i32 into i24.

Time returns the current time in seconds for a lifespan of a stream. Starting and stopping the stream does not affect the passage of time.

Version returns the release number of PortAudio.

VersionText returns the textual description of the PortAudio release.
