AIFF til FLAC Vanlige spørsmål om konvertering
How do I convert AIFF audio to FLAC without losing quality?
+
Upload the AIFF file and the converter chooses the FLAC codec and bitrate to match the source. Lossless FLAC (WAV / FLAC / ALAC) preserves every sample bit-identically; lossy FLAC (MP3 / AAC / OGG / Opus) defaults to 192 kbps which is transparent for most ears.
What bitrate will the resulting FLAC file use?
+
Default is 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; below 96 kbps lossy artifacts become noticeable on music.
Will going from AIFF to FLAC reduce my audio quality?
+
If AIFF is lossy and FLAC is lossless (e.g. MP3 → WAV), the FLAC is no better than the AIFF — you cannot recover information already discarded. If AIFF is lossless and FLAC is lossy, the FLAC codec recompresses; at 192 kbps the result is transparent for most content.
Does the AIFF to FLAC converter keep ID3 / metadata tags?
+
Yes — title, artist, album, year, track number, and album art are read from the AIFF container and written into the FLAC container where the format supports tags. All common targets (MP3, AAC, FLAC, OGG) handle tags fine; raw WAV does not.
Can I batch convert hundreds of AIFF files to FLAC?
+
Yes — drop a folder of AIFF 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 AIFF?
+
By default yes — 48 kHz AIFF stays 48 kHz in FLAC. If you need to downsample for compatibility (96 kHz → 44.1 kHz for CD burning), the sample-rate option applies high-quality resampling in the same encode pass.
Can I normalize loudness when converting AIFF to FLAC?
+
Yes — the loudness-normalize option applies ITU-R BS.1770 / EBU R128 normalization to the FLAC, targeting -14 LUFS (streaming standard) or -16 LUFS (podcast standard). Useful when batching tracks mastered at varying levels.
Will my FLAC play on car stereo, iPod, and Sonos?
+
MP3 plays everywhere. AAC plays on Apple, most Android, and Sonos. FLAC plays on Sonos and Android but not on older iPods. WAV plays on everything but is huge. The advanced device-preset dropdown picks a FLAC codec optimized for your target hardware.
Is my AIFF file private during conversion to FLAC?
+
Yes — uploaded AIFF files are processed in isolated workers and deleted within minutes. We never play back, store long-term, or share the audio content. The full retention window is in /privacy/.
How long does converting a 1-hour AIFF to FLAC take?
+
Same-codec re-mux: 10 to 30 seconds. Re-encode to a different codec: typically 10 to 20% of source duration, so a 1-hour AIFF → FLAC finishes in 6 to 12 minutes. Batch jobs parallelize across workers for further speedups.
Why is the FLAC louder or quieter than the AIFF source?
+
No automatic gain change happens unless you enable the normalize option. If you observe a level change, your audio player or media library is likely applying ReplayGain or per-track normalization on playback — not us. Disable that to hear the true FLAC levels.
Can I convert AIFF downloads from streaming services to FLAC?
+
If the AIFF download is unprotected (no DRM), yes. DRM-encrypted streams (Spotify, Apple Music tracks) are encrypted at the bit level and we cannot process them. Bandcamp, SoundCloud downloads, personal recordings, and podcast files convert cleanly.
