WAV to AAC Transformation FAQ
How do I convert WAV audio to AAC without losing quality?
+
Upload the WAV file and the converter chooses the AAC codec and bitrate to match the source. Lossless AAC (WAV / FLAC / ALAC) preserves every sample bit-identically; lossy AAC (MP3 / AAC / OGG / Opus) defaults to 192 kbps which is transparent for most ears. WAV normally stores raw uncompressed PCM — every sample kept exactly, at whatever bit depth and sample rate was captured. AAC is lossy but more efficient than MP3, and it handles up to 48 channels natively rather than being bolted onto a stereo design.
How much quality do I lose converting WAV to AAC?
+
Some, and it is permanent — this is the one direction where information is genuinely thrown away. WAV holds every sample exactly; AAC discards what a psychoacoustic model predicts you will not hear. At 192 kbps and above that prediction is good enough to be transparent on most material and most equipment. Keep the WAV as your master, because you cannot get back to it from the AAC.
Can I tag the AAC with artist and album information?
+
Yes, and it is a genuine gain over WAV, which has nowhere dependable to store any of it. AAC carries title, artist, album, year, track number and embedded cover art in the container itself, so a music library files it correctly without a manual pass. AAC sounds noticeably better than MP3 below 128 kbps and is the default audio track in MP4, YouTube, Apple Music and broadcast.
Will a long WAV recording upload successfully?
+
Free accounts cap at 100 MB per file, and WAV runs to roughly 10 MB per minute in stereo because nothing about it is compressed — every sample is stored at full width. Ten minutes is already at the limit. Premium lifts the cap considerably, and the format has its own 4 GB ceiling above that, which is why long sessions arrive split into numbered parts; upload them together and they are treated as one job. WAV is enormous — roughly 10 MB per stereo minute at CD quality — and the classic format has a 4 GB ceiling and no room for proper tags.
What bitrate will the resulting AAC file use?
+
Default is 192 kbps for lossy AAC; pass-through for lossless AAC. 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 WAV to AAC reduce my audio quality?
+
If WAV is lossy and AAC is lossless (e.g. MP3 → WAV), the AAC is no better than the WAV — you cannot recover information already discarded. If WAV is lossless and AAC is lossy, the AAC codec recompresses; at 192 kbps the result is transparent for most content.
Does the WAV to AAC converter keep ID3 / metadata tags?
+
Yes — title, artist, album, year, track number, and album art are read from the WAV container and written into the AAC container where the format supports tags. All common targets (MP3, AAC, FLAC, OGG) handle tags fine; raw WAV does not. AAC is Advanced Audio Coding, standardised in 1997 as MPEG-2 Part 7 and designed explicitly to replace MP3.
Can I batch convert hundreds of WAV files to AAC?
+
Yes — drop a folder of WAV 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 AAC keep the same sample rate as WAV?
+
By default yes — 48 kHz WAV stays 48 kHz in AAC. 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 WAV to AAC?
+
Yes — the loudness-normalize option applies ITU-R BS.1770 / EBU R128 normalization to the AAC, targeting -14 LUFS (streaming standard) or -16 LUFS (podcast standard). Useful when batching tracks mastered at varying levels.
Will my AAC 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 an AAC codec optimized for your target hardware. AAC is patent-encumbered, and a handful of very old players still refuse it where they would accept an MP3.
Is my WAV file private during conversion to AAC?
+
Yes — uploaded WAV 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/.
