Echoe is a modern audio-first file sharing and collaboration platform built for music production workflows, replacing Dropbox, WeTransfer, and endless email revisions. Share deliveries and demos with uncompressed WAV/AIFF streaming in the browser, organize tracks into folders and playlists, collect timestamped feedback, manage versions, and stay notified of activity — all in one place. A fully featured free tier is available, with paid plans for larger storage.
