AAC ut WAV Translatio
How do I convert AAC audio to WAV without losing quality?
+
Upload the AAC file and our converter chooses the WAV codec / bitrate combination that matches the source. Lossless target (WAV = WAV / FLAC / ALAC) preserves every sample; lossy target (WAV = MP3 / AAC / OGG) defaults to 192 kbps which is transparent for most ears.
What bitrate does the WAV file use?
+
Default 192 kbps for lossy WAV; pass-through for lossless WAV. Override to 320 kbps for audiophile or 96 kbps for voice / podcast. The choice trades file size against audible fidelity at very low bitrates.
Will going from AAC to WAV reduce my audio quality?
+
If AAC is lossy and WAV is lossless (e.g. MP3 → WAV), the WAV file is no better than the AAC — you can't recover information that's already been thrown away. If AAC is lossless and WAV is lossy, expect the WAV codec to recompress; at 192 kbps this is transparent for most content.
Does the AAC to WAV converter keep ID3 / metadata tags?
+
Yes — title, artist, album, year, track number, album art are read from AAC and written into the WAV container (where the WAV format supports tags, which all common ones do).
Can I batch convert hundreds of AAC files to WAV?
+
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 WAV keep the same sample rate as AAC?
+
By default yes (48 kHz AAC → 48 kHz WAV). 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 AAC to WAV step?
+
Yes — the loudness-normalize option applies ITU-R BS.1770 / EBU R128 normalization to the WAV output, targeting -14 LUFS (streaming standard) or -16 LUFS (podcast standard). Useful when batch-converting tracks with varying mastering levels.
Will the WAV play on my car stereo / iPod / Sonos?
+
MP3 plays universally. AAC plays on Apple, most Android, Sonos. FLAC plays on Sonos and 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 AAC file private during conversion?
+
Yes — uploaded AAC files are processed in isolated workers and deleted within minutes. We never play, store, or share the audio content.
How long does converting a 1-hour AAC to WAV take?
+
Same-codec re-mux: 10-30 seconds. Re-encode to a different codec: typically 10-20% of source duration, so a 1-hour AAC → WAV finishes in 6-12 minutes.
Why is the WAV file louder / quieter than the AAC 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 AAC streaming downloads to WAV?
+
If the AAC download is unprotected (no DRM), yes. DRM-encrypted streaming files (Spotify, Apple Music) are encrypted at the bit level and we can't process them. Sources from Bandcamp, SoundCloud download, and personal recordings convert fine.
