FLAC till AIFF Vanliga frågor om konvertering
How do I convert FLAC audio to AIFF without quality loss?
+
Upload the FLAC file and our converter chooses the AIFF codec / bitrate combination that matches the source. Lossless target (AIFF = WAV / FLAC / ALAC) preserves every sample; lossy target (AIFF = MP3 / AAC / OGG) defaults to 192 kbps which is transparent for spoken-word audiobooks and most music.
What bitrate does the AIFF file use?
+
Default is 192 kbps for lossy AIFF; pass-through for lossless AIFF. Override to 320 kbps for audiophile or 64-96 kbps for spoken-word audiobooks (transparent for voice, halves the file size).
Will going from FLAC to AIFF reduce my audio quality?
+
If FLAC is lossy and AIFF is lossless (e.g. MP3 → WAV), the AIFF file is no better than the FLAC — you can't recover information that's already been thrown away. If FLAC is lossless and AIFF is lossy, expect the AIFF codec to recompress; at 192 kbps this is transparent for most content.
Does the FLAC to AIFF converter keep ID3 / metadata tags?
+
Yes — title, artist, album, year, track number, album art, and chapter markers (important for audiobooks) are read from FLAC and written into the AIFF container where the AIFF format supports tags. M4B audiobook structure round-trips into M4B and AAX → M4B output.
Can I batch convert hundreds of FLAC files to AIFF?
+
Yes — drop a folder of FLAC 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 AIFF keep the same sample rate as FLAC?
+
By default yes (48 kHz FLAC → 48 kHz AIFF). 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 FLAC to AIFF step?
+
Yes — the loudness-normalize option applies ITU-R BS.1770 / EBU R128 normalization to the AIFF 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 AIFF 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 FLAC file private during conversion?
+
Yes — uploaded FLAC 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 FLAC to AIFF 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 AIFF file louder / quieter than the FLAC 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 FLAC downloads to AIFF?
+
No — DRM-encrypted FLAC (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.
