Options

Sounddevice ROS Publisher Node

1. You can list available devices by first running:

   rosrun sounddevice_ros sounddevice_ros_publisher_node.py -l

2. You can select your desired input device by using the -d flag:

   rosrun sounddevice_ros sounddevice_ros_publisher_node.py -d <device id or substring>

3. You can set the sample rate by using the -r flag:

   rosrun sounddevice_ros sounddevice_ros_publisher_node.py -r <sample_rate>

4. You can set the number of channels by using the -c flag (default is 1):

   rosrun sounddevice_ros sounddevice_ros_publisher_node.py -c <num_channels>

   rosrun sounddevice_ros sounddevice_ros_publisher_node.py -s True [Filename]

7. If you want to set the subtype for soundfile saving, you can use the -t flag:

   rosrun sounddevice_ros sounddevice_ros_publisher_node.py -t PCM_24

Sounddevice ROS Subscriber Node

1. You can set the filename that the audio will be saved to (default is a random temp filename):

   rosrun sounddevice_ros sounddevice_ros_subscriber_node.py [Filename]
