Opus chun FLAC Ceisteanna Coitianta maidir le Comhshó
How do I convert Opus audio to FLAC without losing quality?
+
Upload the Opus file and our converter chooses the FLAC codec / bitrate combination that matches the source. Lossless target (FLAC = WAV / FLAC / ALAC) preserves every sample; lossy target (FLAC = MP3 / AAC / OGG) defaults to 192 kbps which is transparent for most ears.
What bitrate does the FLAC file use?
+
Default 192 kbps for lossy FLAC; pass-through for lossless FLAC. 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 Opus to FLAC reduce my audio quality?
+
If Opus is lossy and FLAC is lossless (e.g. MP3 → WAV), the FLAC file is no better than the Opus — you can't recover information that's already been thrown away. If Opus is lossless and FLAC is lossy, expect the FLAC codec to recompress; at 192 kbps this is transparent for most content.
Does the Opus to FLAC converter keep ID3 / metadata tags?
+
Yes — title, artist, album, year, track number, album art are read from Opus and written into the FLAC container (where the FLAC format supports tags, which all common ones do).
Can I batch convert hundreds of Opus files to FLAC?
+
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 FLAC keep the same sample rate as Opus?
+
By default yes (48 kHz Opus → 48 kHz FLAC). 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 FLAC step?
+
Yes — the loudness-normalize option applies ITU-R BS.1770 / EBU R128 normalization to the FLAC output, targeting -14 LUFS (streaming standard) or -16 LUFS (podcast standard). Useful when batch-converting tracks with varying mastering levels.
Will the FLAC 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 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.
How long does converting a 1-hour Opus to FLAC take?
+
Same-codec re-mux: 10-30 seconds. Re-encode to a different codec: typically 10-20% of source duration, so a 1-hour Opus → FLAC finishes in 6-12 minutes.
Why is the FLAC 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 Opus streaming downloads to FLAC?
+
If the Opus 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.
