How do I convert AC3 audio to AAC without losing quality?

Upload the AC3 file and the converter chooses the AAC codec / bitrate combination that matches the source profile. Lossless AAC (WAV / FLAC / ALAC) preserves every sample exactly; lossy AAC (MP3 / AAC / OGG / Opus) defaults to 192 kbps which is transparent for almost all music content.

What bitrate does the AAC file end up at?

Default 192 kbps for lossy AAC; pass-through for lossless AAC. Override to 320 kbps if you want maximum lossy fidelity, 128 kbps for size-constrained podcast distribution, or 96 kbps for voice-only sources where the smaller file matters more than studio detail.

Will going from AC3 to AAC actually reduce my audio quality?

If AC3 is lossy (MP3, AAC) and AAC is lossless (WAV, FLAC), the AAC is no better than the AC3 — you cannot recover information already discarded by the lossy AC3 codec. If AC3 is lossless and AAC is lossy, expect the AAC encoder to recompress; at 192 kbps the loss is imperceptible to most ears.

Does the AC3 to AAC converter keep ID3 / metadata tags?

Yes — title, artist, album, year, track number, album art, BPM, replay-gain are read from the AC3 container and written into the equivalent fields on the AAC container. ID3v2 (MP3), Vorbis comments (OGG, FLAC), MP4 atoms (AAC, M4A), RIFF INFO (WAV), iXML chunks all map cleanly.

Can I batch-convert hundreds of AC3 files into AAC?

Yes — drop a folder of AC3 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. Folder structure is preserved in the output ZIP.

Will the AAC keep the same sample rate as the AC3?

By default yes (a 48 kHz AC3 produces 48 kHz AAC, a 44.1 kHz AC3 produces 44.1 kHz AAC). For specific compatibility — e.g. downsampling 96 kHz studio masters to 44.1 kHz AAC for CD burning, or upsampling 22 kHz voicemail to 44.1 kHz AAC — the sample-rate dropdown applies high-quality SOX-style resampling.

Can I normalize loudness in the AC3 to AAC step?

Yes — the loudness-normalize option applies ITU-R BS.1770 / EBU R128 normalization to the AAC output, targeting -14 LUFS (streaming standard) or -16 LUFS (podcast standard) or a custom value. Useful when batch-converting tracks with varying mastering levels into a single AAC playlist.

Will the AAC play on my car stereo / iPod / Sonos / Bluetooth speaker?

MP3 plays universally on every device made in the last 20 years. AAC plays on Apple, most Android, Sonos, and modern car stereos. FLAC plays on Sonos and recent Android, less well on older iPods. WAV plays on everything but the file is huge. The device-target dropdown picks a safe AAC codec for the platform you specify.

Is my AC3 file private during conversion?

Yes — uploaded AC3 files are processed in isolated workers and deleted within minutes. We never play, store, or share the audio content. The pipeline runs on hardware we control end-to-end; no third-party services receive your file.

How long does converting a 1-hour AC3 to AAC take?

Same-codec re-mux (e.g. AAC inside M4A -> AAC inside MP4): 10-30 seconds. Codec change (e.g. FLAC -> MP3 or WAV -> AAC): typically 10-20% of source duration, so a 1-hour AC3 -> AAC finishes in 6-12 minutes on the standard pipeline.

Why is the AAC file louder or quieter than the AC3 source?

No automatic gain change happens unless the normalize option is turned on. If you do hear a level shift, your audio player or media library may be applying ReplayGain or per-track normalization on playback — turn that off and the AAC sounds bit-identical to the AC3 (for lossless) or perceptually identical (for transparent lossy).

Can I convert AC3 downloads from Bandcamp / SoundCloud into AAC?

If the AC3 download is unprotected (no DRM), yes. DRM-encrypted streaming files (Spotify offline, Apple Music) are encrypted at the bit level and cannot be processed. Sources from Bandcamp purchases, SoundCloud go downloads, podcast feeds, and personal recordings all convert cleanly into AAC.
