AAC chun AIFF Ceisteanna Coitianta maidir le Comhshó
How do I convert AAC audio to AIFF without losing quality?
+
Upload the AAC file and the converter chooses the AIFF codec and bitrate to match the source. Lossless AIFF (WAV / FLAC / ALAC) preserves every sample bit-identically; lossy AIFF (MP3 / AAC / OGG / Opus) defaults to 192 kbps which is transparent for most ears.
What bitrate will the resulting AIFF file use?
+
Default is 192 kbps for lossy AIFF; pass-through for lossless AIFF. 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 AAC to AIFF reduce my audio quality?
+
If AAC is lossy and AIFF is lossless (e.g. MP3 → WAV), the AIFF is no better than the AAC — you cannot recover information already discarded. If AAC is lossless and AIFF is lossy, the AIFF codec recompresses; at 192 kbps the result is transparent for most content.
Does the AAC to AIFF converter keep ID3 / metadata tags?
+
Yes — title, artist, album, year, track number, and album art are read from the AAC container and written into the AIFF 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 AAC files to AIFF?
+
Yes — drop a folder of AAC 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 AAC?
+
By default yes — 48 kHz AAC stays 48 kHz in AIFF. 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 AAC to AIFF?
+
Yes — the loudness-normalize option applies ITU-R BS.1770 / EBU R128 normalization to the AIFF, targeting -14 LUFS (streaming standard) or -16 LUFS (podcast standard). Useful when batching tracks mastered at varying levels.
Will my AIFF 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 AIFF codec optimized for your target hardware.
Is my AAC file private during conversion to AIFF?
+
Yes — uploaded AAC 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 AAC to AIFF 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 AAC → AIFF finishes in 6 to 12 minutes. Batch jobs parallelize across workers for further speedups.
Why is the AIFF louder or quieter than the AAC 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 AIFF levels.
Can I convert AAC downloads from streaming services to AIFF?
+
If the AAC 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.
Is formáid comhaid fuaime neamh-chomhbhrúite é AIFF (Formáid Comhaid Idirmhalartaithe Fuaime) a úsáidtear go coitianta i dtáirgeadh gairmiúil fuaime agus ceoil.
