WAV to Opus Processing FAQ

How do I convert WAV audio to Opus without losing quality?

Upload the WAV file and the converter picks a Opus codec / bitrate combination matched to the source. Lossless target (Opus = WAV / FLAC / ALAC) preserves every sample; lossy target (Opus = MP3 / AAC / OGG / Opus) defaults to 192 kbps which is transparent for most ears.

What bitrate does the Opus file use?

Default 192 kbps for lossy Opus; pass-through for lossless Opus. Override to 320 kbps for audiophile, 256 kbps for high-quality music, or 96 kbps for voice / podcast. The choice trades file size against audible fidelity at very low bitrates.

Will going from WAV to Opus reduce my audio quality?

If WAV is lossy and Opus is lossless (e.g. MP3 → WAV), the Opus file is no better than the WAV source — you cannot recover information that was thrown away by the original lossy encode. If WAV is lossless and Opus is lossy, expect the Opus codec to recompress; at 192 kbps this is transparent for nearly all material.

Does the WAV to Opus converter keep ID3 / metadata tags?

Yes — title, artist, album, year, track number, embedded album art are read from the WAV container and written into the Opus container (every common audio format supports tags). Tags survive even when the underlying codec changes.

Can I batch convert hundreds of WAV files to Opus?

Yes — drop a folder of WAV files in and we process them in parallel. Premium has more parallel workers and no per-file size cap, so a 500-file batch typically finishes in minutes rather than tens of minutes. Tags and folder structure are preserved.

Will the Opus keep the same sample rate as WAV?

By default yes — 48 kHz WAV → 48 kHz Opus, 96 kHz → 96 kHz. If you need to downsample for compatibility (96 kHz studio masters → 44.1 kHz for CD burning), the advanced sample-rate option uses a high-quality resampler (libsoxr or sox-equivalent) with no audible aliasing.

Can I normalize loudness in the WAV to Opus step?

Yes — the loudness-normalize option applies ITU-R BS.1770 / EBU R128 normalization to the Opus output, targeting -14 LUFS (streaming standard) or -16 LUFS (podcast standard). Useful when batch-converting a mixed library whose tracks have wildly varying mastering levels.

Will the Opus play on my car stereo, iPod, or Sonos?

MP3 plays universally on every device built in the last 20 years. AAC plays on Apple, most Android, and Sonos. FLAC plays on Sonos, Android, and most modern car head units; less well on older iPods. WAV plays on everything but is huge. The device-preset option picks the safest Opus codec for the target.

Is my WAV file private during conversion?

Yes — uploaded WAV files are processed in isolated workers and deleted within minutes of completion. We never play, store, fingerprint, or share the audio content. The full data-retention window is documented at /privacy/.

How long does converting a 1-hour WAV to Opus take?

Same-codec re-mux (e.g. FLAC stream inside one container moved to another): 10-30 seconds. Re-encode to a different codec: typically 10-20% of source duration, so a 1-hour WAV → Opus finishes in 6-12 minutes.

Why is the Opus file louder or quieter than the WAV source?

No automatic gain change happens unless you explicitly enable the normalize option. If you see a level difference at playback time, your audio player or media library may be applying ReplayGain or per-track normalization on its own — that is the player, not our pipeline.

Can I convert WAV streaming downloads to Opus?

If the WAV download is unprotected (no DRM), yes. DRM-encrypted streaming files (Spotify offline, Apple Music) are encrypted at the byte level and we cannot decrypt or process them. Sources from Bandcamp, SoundCloud, archive.org, and personal recordings convert without issue.
