WAV to AIFF Conversion FAQ
How do I convert WAV audio to AIFF without losing quality?
+
Upload the WAV 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. WAV normally stores raw uncompressed PCM — every sample kept exactly, at whatever bit depth and sample rate was captured. AIFF stores uncompressed big-endian PCM — the Apple-side equivalent of WAV, with the same bit-for-bit fidelity.
Is WAV to AIFF genuinely lossless?
+
Yes. Both formats keep every sample, so decoding the AIFF returns a bit-identical copy of the audio inside the WAV. Nothing is quantised, nothing is discarded, and the conversion can be repeated indefinitely without accumulating artefacts. What changes is the file size and which software will open it.
Can I tag the AIFF with artist and album information?
+
Yes, and it is a genuine gain over WAV, which has nowhere dependable to store any of it. AIFF 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. AIFF is the studio interchange format on macOS, handles metadata better than plain WAV, and imports into Logic and Pro Tools instantly.
Will the AIFF play in my car or on older hardware?
+
Often not. WAV is decoded by essentially everything, including car head units and elderly players; AIFF needs software that knows the codec, which standalone hardware frequently does not have. If the destination is a car stereo or a portable player, that is a strong argument for staying on WAV. AIFF is as large as WAV with worse support outside the Apple world, so it is a poor choice for distribution.
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 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 WAV to AIFF reduce my audio quality?
+
If WAV is lossy and AIFF is lossless (e.g. MP3 → WAV), the AIFF is no better than the WAV — you cannot recover information already discarded. If WAV is lossless and AIFF is lossy, the AIFF codec recompresses; at 192 kbps the result is transparent for most content.
Does the WAV to AIFF 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 AIFF container where the format supports tags. All common targets (MP3, AAC, FLAC, OGG) handle tags fine; raw WAV does not. AIFF is Apple’s Audio Interchange File Format from 1988, built on the same IFF chunk design as AVI’s RIFF.
Can I batch convert hundreds of WAV files to AIFF?
+
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 AIFF keep the same sample rate as WAV?
+
By default yes — 48 kHz WAV 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 WAV 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 an AIFF codec optimized for your target hardware.
