Question: Is there a free online recording studio that allows me to record high-quality audio and video with multiple participants?

Podcastle is an all-in-one web-based content creation studio that handles up to 10 people with high-quality audio and video. It's got features like AI noise reduction, a video editor with custom branding and a hosting hub for publishing your content. Podcastle has an easy-to-use interface that's good for creating podcasts, audiobooks, internal communications and more.

Another good option is Waveroom, which can handle up to 5 people, including the host, recording high-quality tracks.
