Detailed Description
\ Audio sink using PORTAUDIO
Input samples must be in the range [-1,1].

Member Function Documentation
| bool audio_portaudio_sink::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.

The user must override work to define the signal processing code
