A good clip preserves enough lead-in to explain who or what the speaker is discussing. In Audio Trimmer, start slightly before the sentence and stop after the thought finishes, not in the middle of a breath or word.
Listen to the exported file, not just the preview. Check that the context remains fair, the audio plays from start to finish, and the original recording is saved separately. Get permission before sharing private speech.
