Perform all testing in a Sandbox environment
Reach out to your account representative if you need Sandbox access. All dev testing should occur in that environment while prepping for audio replacement.
While Replacing audio on a Streem video is made easy through our API, reverting back to the original audio is incredibly difficult. Developers should consider audio replacement as permanent and irreversible. A video file may have it's audio replaced several times and this would be the case on each. once replaced, the prior audio is no longer available.
