⚠️ Currently rewriting from scratch using gstreamer (on the dev branch)

Check out the real-life GTA: San Andreas radio set for an example use of this library

A virtual FM band playing simultaneous sounds over virtual frequencies.

 Track 0 Track 1 Track 2 Track 3 Track N | | | | | |--------------|--------------|--------------|---- - - - --| <------------------------------------------------- - - - --> virtual frequency 

Technically, it's a mixer with multiple tracks that takes care of the volume of each track (fade in / fade out) while moving along the virtual frequency.

curl https://raw.githubusercontent.com/raphaelyancey/Virtual_FM_Band/master/install.sh | bash

Read the install.sh script for details.

In a nutshell, it:

• Installs required packages
• Clones this repository
• Installs Python dependencies

• Handle streams as input
• Add static noise between stations
• Make swmixer play the files in loop
• Do not play if the file is not to be heard anyway
• Random start position

After installing the required Python packages, execute this script in a Python shell.

import pyaudio p = pyaudio.PyAudio() info = p.get_host_api_info_by_index(0) numdevices = info.get('deviceCount') for i in range(0, numdevices): if (p.get_device_info_by_host_api_device_index(0, i).get('maxOutputChannels')) > 0: print "Output Device id ", i, " - ", p.get_device_info_by_host_api_device_index(0, i).get('name')

Make sure you specified the correct device index in the .env file. To list the device indexes, see https://stackoverflow.com/a/39677871/2544016.
