Example: David Gooding lecture.
Keep the conversation worth listening to.
You may already have the interview, lesson, or explanation you wanted. Try restoring that recording before arranging another take. Diffio processes recorded speech and lets you compare the result in your browser.
Judge the parts that matter.
Start with a passage where the background is distracting. Compare the clarity of the words and the sound of the voice. The source recording affects the result, so listen before deciding to export.
