That causes the transmission to gain a delay of up to 0.5 seconds. The transmission arrives on the receivers with 24000 Hz in mono channel. The transmission is not encrypted. In a dedicated network Speekie can be used with about 50 connected receivers. The more receivers are connected, the more the signal quality decreases and the delay may increase. Interruptions may occur. This mainly is influenced by your network properties.
