Why convert
Opus — the voice-message format of Telegram and WhatsApp; good even at low bitrates. AIFF — Apple's uncompressed audio, the Mac counterpart of WAV. Needed for editing when a program asks for AIFF.
What changes in the file
Quality will not improve: what Opus compression threw away is gone; the file just gets bigger.
Which settings to pick
A lossless format with little to tune: you can trim the recording and change the volume.
