pyssc

A Sennheiser Sound Control Protocol (SSC) Client Implementation for Python

Introduction

The Sennheiser Sound Control Protocol is a specific adaption of Open Sound Control. Pyssc is a simple client implementation that allows users to discover SSC Devices in their networks and subsequently communicate with those Devices via SSC.

Installation

Pyssc is published to pypi.org/pyssc.

pip install pyssc

Usage

Initially you will have to find out the IP Addresses of your SSC Devices. If you don't know them you can try and find them using zeroconf.

import pyssc as ssc
found_setup = ssc.scan()

When you know all the IPs you can store the setup as a JSON file.

found_setup.to_json('setup.json')

Here's an example setup JSON:

{
    "Device 1": "fe80::2a36:38ff:fe60:7515",
    "Device 2": "fe80::2a36:38ff:fe60:784f",
}

Once you have defined your setups as a JSON you don't need to scan anymore. Simply import your setup at the beginning of your session.

found_setup = ssc.Ssc_device_setup()
found_setup.from_json('setup.json')

Now you can send and receive SSC either to and from a single device

device_1 = found_setup.ssc_devices[0]
ssc_transaction = device_1.send_ssc('{"audio":{"out":{"mute":true}}}')

or the whole setup.

found_setup.send_all('{"audio":{"out":{"mute":true}}}')

Please note that Unix systems require you to specify the network interface. The default value here is "%eth0". On Windows you can specify an empty String as the Value for "interface".

ssc_transaction = device_1.send_ssc('{"audio":{"out":{"mute":true}}}', interface = "")

To find out which commands work for your specific SSC Device please refer to the SSC Documentation.
