Why convert
WAV — uncompressed sound from recorders and studio software; the files are large. Opus — the voice-message format of Telegram and WhatsApp; good even at low bitrates.
What changes in the file
Lossy compression removes part of the sound; at 256–320 kbit/s it is barely audible.
Which settings to pick
Use 128–192 kbit/s for music; 64 is enough for speech.
