Riverside is a web-based platform for recording high-quality audio and video from remote participants. Unlike Zoom or Skype, Riverside records each person's microphone locally at high bitrate, capturing studio-quality audio. It handles synchronization, uploading, and management of recordings. Primary use: podcasts and interviews with remote participants where quality matters. The workflow: create a session, send link to guests, everyone joins and records locally, Riverside syncs and uploads everything.
