WAV to Opus Transformation FAQ
What bitrate will the resulting Opus file use?
+
A lossy Opus is encoded at 192 kbps by default. The Audio Quality setting also offers 320 kbps for the best quality and 128 kbps for a smaller file. A lossless Opus (WAV, FLAC) ignores the bitrate and keeps every sample.
How much quality do I lose converting WAV to Opus?
+
Some, and it is permanent — this is the one direction where information is genuinely thrown away. WAV holds every sample exactly; Opus discards what a psychoacoustic model predicts you will not hear. At 192 kbps and above that prediction is good enough to be transparent on most material and most equipment. Keep the WAV as your master, because you cannot get back to it from the Opus. WAV normally stores raw uncompressed PCM — every sample kept exactly, at whatever bit depth and sample rate was captured. Opus scales from 6 kbps mono speech to 510 kbps stereo music in the same bitstream and switches modes automatically.
Can I tag the Opus with artist and album information?
+
Yes, and it is a genuine gain over WAV, which has nowhere dependable to store any of it. Opus carries title, artist, album, year, track number and embedded cover art in the container itself, so a music library files it correctly without a manual pass. Opus is the best-sounding lossy codec at low bitrates by a clear margin, and it powers WhatsApp voice notes, Discord and WebRTC.
Will the Opus play in my car or on older hardware?
+
Often not. WAV is decoded by essentially everything, including car head units and elderly players; Opus needs software that knows the codec, which standalone hardware frequently does not have. If the destination is a car stereo or a portable player, that is a strong argument for staying on WAV. Opus is almost never supported by standalone hardware — assume software playback only, and expect car stereos to ignore it.
Will going from WAV to Opus reduce my audio quality?
+
If WAV is lossy and Opus is lossless (e.g. MP3 → WAV), the Opus is no better than the WAV — you cannot recover information already discarded. If WAV is lossless and Opus is lossy, the Opus codec recompresses; at 192 kbps the result is transparent for most content.
Can I batch convert hundreds of WAV files to Opus?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
Will the Opus keep the same sample rate as WAV?
+
By default yes — 48 kHz WAV stays 48 kHz in Opus. If you need to downsample for compatibility (96 kHz → 44.1 kHz for CD burning), the sample-rate option applies high-quality resampling in the same encode pass.
Can I normalize loudness when converting WAV to Opus?
+
Not in this step. The converter has no loudness setting and leaves the level as it is. To even out the volume, run the finished Opus through a Normalize tool on this site.
Will my Opus play on car stereo, iPod, and Sonos?
+
MP3 plays almost everywhere. AAC plays on Apple devices, most Android phones and Sonos. FLAC plays on Sonos and Android but not on older iPods, and WAV plays on nearly everything but makes large files. There are no device presets on this page, so choose the target format your player supports.
Is my WAV file private during conversion to Opus?
+
Yes. Uploaded WAV files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted Opus are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
