Heads up before converting to Opus
What this specific conversion changes about your audio.
Converting WAV to Opus discards audio data
WAV is lossless, but Opus is lossy — this conversion permanently throws away part of the signal to save space. Keep your WAV file as the master and use the Opus copy for sharing or playback.
Best practices for Opus
Small choices that keep your output sounding right.
- Play the first converted file before batch-converting the rest, so you catch a wrong setting early.
- For Opus, choose a bitrate that fits the use: 192–256 kbps keeps most music transparent, 320 kbps for archival-grade lossy.
When NOT to convert to Opus
Cases where a different format serves you better.
When you need an editable master
If you might re-edit or re-export later, keep the lossless WAV original and skip flattening it to Opus. Lossy targets are for delivery, not for archiving the source of truth.
When the file must play on older devices
Opus is not supported everywhere (Wide). For old phones, car stereos, or legacy software, MP3 or AAC is a safer choice than Opus.
