Instant Voice Cloning & STS: Remove Noise

ElevenLabs has added the optional ability to remove background noise from samples uploaded for Instant Voice Cloning, as well as audio supplied for Voice Changer (also known as Speech to Speech).  This utilizes ElevenLabs Voice Isolator technology and there is currently no additional charge for using the optional clean-up step.  It is available when using Instant Voice Cloning and Voice Changer on the ElevenLabs website, as well as the Add Voice API endpoint by setting the remove_background_noise body parameter to true.

This is highly recommended if the audio has noise, but if it is already clean and of high-quality, you may get better results not enabling the background noise removal.
