In our scenerio, we have a setting that whenever the bot's frequency is within the accceptable range of the radio, the CW sound (example: SOS but it would play ... --- ...) on the radio. One problem is that if multiple bots playing sound at the same time (for our case, 8 bots), it would be very chaotic.
Dr. Stonedahl suggested to only allow 2 bots within a specific range, so that not many bots would be playing sound at the same time. Changing the volume of the bots based on how off they are from the radio filter is also an option. One of our group member suggested using existed framework to merge the audio lines into one stream. Do your group have the same problem? Is there any idea on mixing sound?
