How do I convert AIFF audio to AC3 without losing quality?
+
Upload the AIFF file and our converter picks a AC3 codec / bitrate combination matched to the source. Lossless target (AC3 = WAV / FLAC / ALAC) preserves every sample; lossy target (AC3 = MP3 / AAC / OGG / Opus) defaults to 192 kbps which is transparent for most ears.
What bitrate does the AC3 file use?
+
Default 192 kbps for lossy AC3; pass-through (no bitrate dial) for lossless AC3. Override to 320 kbps for audiophile output, or 96 kbps for voice / podcast where smaller files matter more than fidelity at the extremes.
Will going from AIFF to AC3 reduce my audio quality?
+
If AIFF is lossy and AC3 is lossless (e.g. MP3 -> WAV), the AC3 file is no better than the AIFF — you cannot recover information that was already thrown away. If AIFF is lossless and AC3 is lossy, the AC3 codec recompresses; at 192 kbps this is transparent for most content.
Does the AIFF to AC3 converter keep ID3 / metadata tags?
+
Yes — title, artist, album, year, track number, and embedded album art are read from AIFF and written into the AC3 container where the AC3 format supports tags (which all common ones do).
Can I batch convert hundreds of AIFF files to AC3?
+
Yes — drop a folder of AIFF files in and we process them in parallel. Pro 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 AC3 keep the same sample rate as AIFF?
+
By default yes (48 kHz AIFF -> 48 kHz AC3). If you need to downsample for compatibility (e.g. 96 kHz -> 44.1 kHz for CD burning) the advanced sample-rate option handles this with a high-quality polyphase resampler.
Can I normalize loudness in the AIFF to AC3 step?
+
Yes — the loudness-normalize option applies ITU-R BS.1770 / EBU R128 normalization to the AC3 output, targeting -14 LUFS (streaming standard) or -16 LUFS (podcast standard). Useful when batch-converting tracks with varying mastering levels.
Will the AC3 play on my car stereo / iPod / Sonos?
+
MP3 plays universally. AAC plays on Apple, most Android, and Sonos. FLAC plays on Sonos and modern 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 AIFF file private during conversion?
+
Yes — uploaded AIFF files are processed in isolated workers and deleted within minutes. We never play, store, or share audio content. See /privacy/ for the data retention window.
How long does converting a 1-hour AIFF to AC3 take?
+
Same-codec re-mux: 10-30 seconds. Re-encode to a different codec: typically 10-20% of source duration, so a 1-hour AIFF -> AC3 finishes in 6-12 minutes on the standard pipeline.
Why is the AC3 file louder / quieter than the AIFF 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 is probably applying ReplayGain or per-track normalization on playback — not us.
Can I convert AIFF downloads to AC3?
+
If the AIFF download is unprotected (no DRM), yes. DRM-encrypted streaming files (Spotify, Apple Music) are encrypted at the bit level and we cannot process them. Sources from Bandcamp, SoundCloud, and personal recordings convert fine.
