How do I convert AC3 audio to Opus without losing quality?

Upload the AC3 file and our converter chooses the Opus codec / bitrate combination that matches the source. Lossless target (Opus = WAV / FLAC / ALAC) preserves every sample; lossy target (Opus = MP3 / AAC / OGG) 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 or 96 kbps for voice / podcast. The choice trades file size against audible fidelity at very low bitrates.

Will going from AC3 to Opus reduce my audio quality?

If AC3 is lossy and Opus is lossless (e.g. MP3 → WAV), the Opus file is no better than the AC3 — you can't recover information that's already been thrown away. If AC3 is lossless and Opus is lossy, expect the Opus codec to recompress; at 192 kbps this is transparent for most content.

Does the AC3 to Opus converter keep ID3 / metadata tags?

Yes — title, artist, album, year, track number, album art are read from AC3 and written into the Opus container (where the Opus format supports tags, which all common ones do).

Can I batch convert hundreds of AC3 files to Opus?

Yes — drop a folder of AC3 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 Opus keep the same sample rate as AC3?

By default yes (48 kHz AC3 → 48 kHz Opus). 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 AC3 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 tracks with varying mastering levels.

Will the Opus play on my car stereo / iPod / Sonos?

MP3 plays universally. AAC plays on Apple, most Android, Sonos. FLAC plays on Sonos and Android, less well on older iPods. WAV plays on everything but is huge. The advanced options include device presets for these common targets.

Is my AC3 file private during conversion?

Yes — uploaded AC3 files are processed in isolated workers and deleted within minutes. We never play, store, or share the audio content.

How long does converting a 1-hour AC3 to Opus take?

Same-codec re-mux: 10-30 seconds. Re-encode to a different codec: typically 10-20% of source duration, so a 1-hour AC3 → Opus finishes in 6-12 minutes.

Why is the Opus file louder / quieter than the AC3 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 AC3 streaming downloads to Opus?

If the AC3 download is unprotected (no DRM), yes. DRM-encrypted streaming files (Spotify, Apple Music) are encrypted at the bit level and we can't process them. Sources from Bandcamp, SoundCloud download, and personal recordings convert fine.
