gnuradio.audio

Blocks to connect to audio sources (mic-in) and sinks (speaker-out) ports on a computer.

The underlying hardware driver is system and OS dependent and this module should automatically discover the correct one to use.

gnuradio.audio.source(int sampling_rate, std::string const device_name="", bool ok_to_block=True) → source_sptr

Creates a source from an audio device.

Constructor Specific Documentation:

Creates a source from an audio device at a specified sample_rate. The specific audio device to use can be specified as the device_name parameter. Typical choices are:

• pulse, hw:0,0, plughw:0,0, surround51, /dev/dsp

Parameters:

• sampling_rate –
• device_name –
• ok_to_block –
