# Audio Echo allows you to output the 'speaking voice' and the 'cue voice' to different output devices, ie one headphone and one speaker. The purpose behind this is so that the user can use a headphone to read the cue output directly to them so no one else hears it, then use a loud speaker for the speaking voice for everyone to hear. Unfortunately this is an advanced feature and is not easy to setup and requires specific hardware, so please bear that in mind. Audio is made up of two separate audio signals, one that is for the 'left' channel and one for the 'right' channel. By default Echo, and everything else, outputs to both channels. You can enable 'Directional Audio' in the audio settings of Echo, you can then chose which channel you want to send each voice through. To seperate the channels you will need an [audio splitter cable](https://www.amazon.co.uk/HosaTech-YMP-137-3-5mm-Stereo-Breakout/dp/B000068O5E/ref=sr_1_7?crid=1GAL99VANVPGO\&dib=eyJ2IjoiMSJ9.PSi88q6Gy1uW3Davw5yiI4cGrsJ7bl2_s94g8_rSM1dPK6znR--Azjmk9wUeqRiXkCKb3W7EAX2IYpdEUL706sVP2H6DKUHB2Vd85mHgHPKKZyVK1n3xx65PPi4Iydkjoxw_Piq6lgT4mx-hCTi6aNnjDqAcvWnCFHC82uM0B3qmw3BFk6xJo8GfurnKJQYgc0vzPwNA6Hz9Z5n569cHRD_B1PsRgCPmzJxIKse6ELTD0C2ZtQIDAxZlqwfhNuKgVD9G0L0dsCiEHJFFKxSkz9sH3Anyb9zEUSayHP3cPvQ.j_HJYUNrK-CVUgzma_tXogfYmzFrvHprokJioVmHPow\&dib_tag=se\&keywords=stereo%2Bbreakout%2Bcable%2B3.5\&qid=1722593708\&sprefix=stereo%2Bbreakout%2Bcable%2Caps%2C102\&sr=8-7\&th=1).
