Detailed Description

Audio sink using PORTAUDIO

Input samples must be in the range [-1,1].


Constructor & Destructor Documentation

audio_portaudio_sink::audio_portaudio_sink ( int  sampling_rate,
const std::string  device_name,
bool  ok_to_block 
)
audio_portaudio_sink::~audio_portaudio_sink ( )

Member Function Documentation

bool audio_portaudio_sink::check_topology ( int  ninputs,
int  noutputs 
) [virtual]

Confirm that ninputs and noutputs is an acceptable combination.

Parameters:
ninputsnumber of input streams connected
noutputsnumber of output streams connected
Returns:
true if this is a valid configuration for this block.

This function is called by the runtime system whenever the topology changes. Most classes do not need to override this. This check is in addition to the constraints specified by the input and output gr_io_signatures.

Reimplemented from gr_basic_block.

int audio_portaudio_sink::work ( int  noutput_items,
gr_vector_const_void_star input_items,
gr_vector_void_star output_items 
) [virtual]

just like gr_block::general_work, only this arranges to call consume_each for you

The user must override work to define the signal processing code

Implements gr_sync_block.
