Detailed Description
audio source using OSX
Input signature is one or two streams of floats. Samples must be in the range [-1,1].

Member Function Documentation
| bool audio_osx_source::check_topology | ( | int | ninputs, |
| int | noutputs | ||
| ) | [virtual] |
Confirm that ninputs and noutputs is an acceptable combination.
- Parameters:
-
ninputs number of input streams connected noutputs number 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.
| bool audio_osx_source::IsRunning | ( | ) |
| bool audio_osx_source::start | ( | ) | [virtual] |
Called to enable drivers, etc for i/o devices.
This allows a block to enable an associated driver to begin transfering data just before we start to execute the scheduler. The end result is that this reduces latency in the pipeline when dealing with audio devices, usrps, etc.
Reimplemented from gr_block.
| bool audio_osx_source::stop | ( | ) | [virtual] |
Called to disable drivers, etc for i/o devices.
Reimplemented from gr_block.
