When you hear yourself with a delay from the return stream, there are a few things you have to check:
- You need to use a headphone, to avoid the laptops microphone to pick up the studio’s return stream, LUCI has no echo cancelling.
- It could be that the Laptop microphone is routed by the OS to the laptop’s speaker: please uncheck the Microphone’s Property “Listen to this device”.
- The studio is sending a stream back to you containing the broadcasted audio with your stream mixed in, so you hear yourself with some delay. The studio needs to set up a mix-minus audio routing configuration, where you only get the audio broadcasted, but without your own voice.
- On Mobiles we have a special setting called Xtalk compensation
With this option the cross talk (leakage) on the headset will be cancelled. If you use a headset or MIKI cable and the radio-station hears themselves back too loud, turning this “Xtalk compensate” on is advised. This will cause LUCI to output inverted audio on the L and R headphone output, thereby cancelling any cross-talk back into the microphone input.
