WAV to Opus Conversion FAQ
How do I convert WAV audio to Opus without losing quality?
+
Upload the WAV file and the converter chooses the Opus codec / bitrate combination that matches the source profile. Lossless Opus (WAV / FLAC / ALAC) preserves every sample exactly; lossy Opus (MP3 / AAC / OGG / Opus) defaults to 192 kbps which is transparent for almost all music content. 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.
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.
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 a long WAV recording upload successfully?
+
Free accounts cap at 100 MB per file, and WAV runs to roughly 10 MB per minute in stereo because nothing about it is compressed — every sample is stored at full width. Ten minutes is already at the limit. Premium lifts the cap considerably, and the format has its own 4 GB ceiling above that, which is why long sessions arrive split into numbered parts; upload them together and they are treated as one job. WAV is enormous — roughly 10 MB per stereo minute at CD quality — and the classic format has a 4 GB ceiling and no room for proper tags.
What bitrate does the Opus file end up at?
+
Default 192 kbps for lossy Opus; pass-through for lossless Opus. Override to 320 kbps if you want maximum lossy fidelity, 128 kbps for size-constrained podcast distribution, or 96 kbps for voice-only sources where the smaller file matters more than studio detail.
Will going from WAV to Opus actually reduce my audio quality?
+
If WAV is lossy (MP3, AAC) and Opus is lossless (WAV, FLAC), the Opus is no better than the WAV — you cannot recover information already discarded by the lossy WAV codec. If WAV is lossless and Opus is lossy, expect the Opus encoder to recompress; at 192 kbps the loss is imperceptible to most ears.
Does the WAV to Opus converter keep ID3 / metadata tags?
+
Yes — title, artist, album, year, track number, album art, BPM, replay-gain are read from the WAV container and written into the equivalent fields on the Opus container. ID3v2 (MP3), Vorbis comments (OGG, FLAC), MP4 atoms (AAC, M4A), RIFF INFO (WAV), iXML chunks all map cleanly. Opus is an IETF standard from 2012 that merged Skype’s SILK speech codec with Xiph’s CELT music codec into one design.
Can I batch-convert hundreds of WAV files into 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 finishes in minutes rather than tens of minutes. Folder structure is preserved in the output ZIP.
Will the Opus keep the same sample rate as the WAV?
+
By default yes (a 48 kHz WAV produces 48 kHz Opus, a 44.1 kHz WAV produces 44.1 kHz Opus). For specific compatibility — e.g. downsampling 96 kHz studio masters to 44.1 kHz Opus for CD burning, or upsampling 22 kHz voicemail to 44.1 kHz Opus — the sample-rate dropdown applies high-quality SOX-style resampling.
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) or a custom value. Useful when batch-converting tracks with varying mastering levels into a single Opus playlist.
Will the Opus play on my car stereo / iPod / Sonos / Bluetooth speaker?
+
MP3 plays universally on every device made in the last 20 years. AAC plays on Apple, most Android, Sonos, and modern car stereos. FLAC plays on Sonos and recent Android, less well on older iPods. WAV plays on everything but the file is huge. The device-target dropdown picks a safe Opus codec for the platform you specify.
