Opus да WMA Частыя пытанні па канверсіі
How do I convert Opus audio to WMA without quality loss?
+
Upload the Opus file and our converter chooses the WMA codec / bitrate combination that matches the source. Lossless target (WMA = WAV / FLAC / ALAC) preserves every sample; lossy target (WMA = MP3 / AAC / OGG) defaults to 192 kbps which is transparent for spoken-word audiobooks and most music.
What bitrate does the WMA file use?
+
Default is 192 kbps for lossy WMA; pass-through for lossless WMA. Override to 320 kbps for audiophile or 64-96 kbps for spoken-word audiobooks (transparent for voice, halves the file size).
Will going from Opus to WMA reduce my audio quality?
+
If Opus is lossy and WMA is lossless (e.g. MP3 → WAV), the WMA file is no better than the Opus — you can't recover information that's already been thrown away. If Opus is lossless and WMA is lossy, expect the WMA codec to recompress; at 192 kbps this is transparent for most content.
Does the Opus to WMA converter keep ID3 / metadata tags?
+
Yes — title, artist, album, year, track number, album art, and chapter markers (important for audiobooks) are read from Opus and written into the WMA container where the WMA format supports tags. M4B audiobook structure round-trips into M4B and AAX → M4B output.
Can I batch convert hundreds of Opus files to WMA?
+
Yes — drop a folder of Opus 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.
Will the WMA keep the same sample rate as Opus?
+
By default yes (48 kHz Opus → 48 kHz WMA). If you need to downsample for compatibility (e.g. 96 kHz → 44.1 kHz for CD burning) the advanced sample-rate option does this with high-quality resampling.
Can I normalize loudness in the Opus to WMA step?
+
Yes — the loudness-normalize option applies ITU-R BS.1770 / EBU R128 normalization to the WMA output, targeting -14 LUFS (streaming standard), -16 LUFS (podcast standard), or -23 LUFS (audiobook standard). Useful when batch-converting tracks with varying mastering levels.
Will the WMA play on my car stereo / iPod / audiobook app?
+
MP3 plays universally. AAC plays on Apple, most Android, Sonos. FLAC plays on Sonos and Android, less well on older iPods. M4B audiobooks play with chapter navigation on iOS Books, Audiobookshelf, and Smart Audiobook Player. The advanced options include device presets.
Is my Opus file private during conversion?
+
Yes — uploaded Opus files are processed in isolated workers and deleted within minutes. We never play, store, or share the audio content. Especially important when working with personal audiobook libraries.
How long does converting a 10-hour audiobook Opus to WMA take?
+
Same-codec re-mux: 10-30 seconds. Re-encode to a different codec: typically 10-20% of source duration, so a 10-hour audiobook finishes in 60-120 minutes. Chapter markers survive the round-trip and split cleanly.
Why is the WMA file louder / quieter than the Opus source?
+
No automatic gain change happens unless you turn on the normalize option. If you do see a level change, your audio player or media library may be applying ReplayGain or per-track normalization on playback — not us.
Can I convert DRM-protected Opus downloads to WMA?
+
No — DRM-encrypted Opus (Audible AAX with personal activation, Apple Music) is encrypted at the bit level and we can't process it. Sources from public-domain audiobook archives, your own recordings, or Bandcamp downloads convert fine.
