Need help?How to Convert WAV to AIFC Online
- Upload Your WAV File: Drag and drop or click "Add Files" to select WAV files from your computer. Batch is supported — drop in an entire folder of recordings or session bounces and convert them in one pass.
- Pick Audio Codec: Default for AIFC is PCM 16-bit Big Endian (true lossless, the AIFF-family native encoding on classic Mac). Switch to PCM A-law or PCM mu-law for an 8-bit telephony-style 2:1 compression, or PCM 24-bit Little Endian for studio masters. The codec choice is what makes AIFC different from plain AIFF — AIFF is PCM-only, AIFC carries the codec ID in the COMM chunk.
- Set Audio Channel, Sample Rate, and Trim (Optional): Keep "Original" to preserve the source, or drop stereo to mono and downsample from 48 kHz to 44.1 / 22.05 / 8 kHz to shrink files further. Use the trim section (start time + duration) to extract a clip without re-recording.
- Convert and Download: Click Convert. Files process on our servers and download individually or as a ZIP — no sign-up, no watermark.
Why Convert WAV to AIFC?
WAV (developed by IBM and Microsoft in 1991) and AIFF (Apple, 1988) are the two classic uncompressed PCM containers. AIFF-C — usually written AIFC — was added in 1991 as an extension that keeps the AIFF container but allows the audio chunk to use a named codec instead of raw PCM. Per the AIFF-C specification, the codec ID lives in the COMM chunk and can be NONE (uncompressed PCM, big-endian), alaw, ulaw, ima4 (IMA ADPCM 4:1), fl32/fl64 (32/64-bit float), or various legacy Apple codecs (MAC3, MAC6, ACE2, ACE8). Common reasons to convert WAV → AIFC:
- Mac-native pro audio workflows — Logic Pro, GarageBand, Final Cut Pro, and ProTools on macOS all read AIFC. Delivering AIFC instead of WAV keeps byte-order endianness aligned with the AIFF lineage that these tools were built around.
- Compression inside an AIFF-family container — If a downstream tool only accepts the AIFF/AIFC container but you need a smaller file, AIFC with mu-law or A-law gives you a 2:1 reduction (16-bit PCM down to 8-bit log-companded samples) without leaving the container.
- Float audio for mastering chains — Some mastering plugins and DAW bounce stages expect 32-bit float. AIFC carries
fl32natively where plain AIFF would force a re-container into WAV or CAF. - Game audio for older Mac/iOS toolchains — Classic Mac game pipelines and older iOS audio toolchains (pre-Core Audio standardization on CAF) shipped AIFC sound effects with IMA ADPCM compression. Legacy ports still expect this format.
- Archival of telephony-grade voice — Voicemail systems, IVR prompts, and older field-recorder dumps that originate as mu-law or A-law fit naturally into AIFC without re-encoding the samples.
- Cross-platform interchange when AIFF is the agreed container — Studios that standardize on AIFF for delivery sometimes accept AIFC for compressed variants of the same content (announcement beds, telephone-on-hold loops) so everything is in one container family.

AIFC Codec Quick Guide
| AIFC codec ID | Description | Compression | When to pick |
|---|---|---|---|
NONE (PCM 16-bit BE) |
Big-endian uncompressed PCM | 1:1 (lossless) | Default — true AIFF-family lossless, indistinguishable from WAV PCM bit-for-bit |
| PCM 24-bit LE | 24-bit linear PCM | 1:1 (lossless) | Studio masters from 24-bit DAW bounces |
alaw (PCM A-law) |
8-bit log-companded, ITU-T G.711 | ~2:1 lossy | European telephony, IVR prompts, voicemail |
ulaw (PCM mu-law) |
8-bit log-companded, ITU-T G.711 | ~2:1 lossy | North American / Japanese telephony, voicemail, announcement beds |
ima4 (IMA ADPCM) |
4-bit adaptive PCM | ~4:1 lossy | Classic Mac/iOS game sound effects, short loops |
fl32 / fl64 |
32/64-bit IEEE float | 2:1 / 4:1 larger than 16-bit | Headroom-preserving masters; processing chains expecting float |
Frequently Asked Questions
Is AIFC actually different from AIFF, or is it just a renamed extension?
It is different at the file-format level, even though the container looks the same. Standard AIFF supports only uncompressed big-endian PCM. AIFC ("AIFF-C", added to the AIFF spec in 1991) keeps the same FORM container but stores a 4-character codec ID in the COMM chunk — so the same .aifc file can hold PCM, A-law, mu-law, IMA ADPCM, or 32/64-bit float audio. If you only need lossless PCM and you want maximum compatibility, convert to AIFF instead.
Why is the default codec PCM Big-Endian instead of mu-law or IMA?
Because AIFC's whole reason to exist is to extend AIFF with optional codecs while still defaulting to AIFF's native encoding. Big-endian 16-bit PCM is what the AIFF lineage uses; an AIFC file with codec NONE is byte-for-byte equivalent in audio data to an AIFF file (the wrapper differs). Pick a lossy codec (mu-law, A-law, IMA) only when you specifically need the size reduction.
Will Windows Media Player or VLC play the AIFC?
VLC plays AIFC reliably on Windows, macOS, and Linux. Windows Media Player has historically been inconsistent — newer Windows 11 Media Player builds open most AIFC files, but the codec-specific variants (A-law, mu-law, IMA4) sometimes fail. If you need a guaranteed Windows-native playback path, convert WAV to MP3 or stick with WAV.
Will the conversion be lossless?
Lossless if you keep the default codec (PCM 16-bit Big Endian) — that's a sample-format and byte-order change only; no audio data is discarded. Lossy if you switch to A-law / mu-law (8-bit companded) or IMA ADPCM (4-bit adaptive). The codec column in the AIFC Quick Guide above marks which are which.
My source WAV is 24-bit / 96 kHz. Will AIFC preserve that?
Yes, with PCM 24-bit Little Endian selected. The sample rate carries through unchanged unless you explicitly downsample via the Audio Sample Rate dropdown. Note that classic AIFC tooling sometimes expects big-endian PCM, so very old Mac applications may not parse a 24-bit LE AIFC — modern DAWs handle both.
Why would I pick AIFC over FLAC if I want compression?
You usually wouldn't. FLAC is lossless and typically achieves ~50-60% of the original size; AIFC's lossy mu-law / A-law only reaches ~50% with audible quality loss. AIFC compression makes sense only when the receiving tool requires the AIFF container family. For general lossless compression, convert WAV to FLAC is the better choice.
Can I batch-convert a folder of WAV stems to AIFC?
Yes — drop the whole folder in at once. Each WAV converts independently on our servers with the same codec, sample rate, and channel settings, and the files download individually or bundled as a ZIP. Useful for delivering session stems to a Logic / ProTools editor on Mac.
What if I need the reverse direction later?
XConvert has the round-trip page at AIFC to WAV. Going AIFC → WAV is lossless when the AIFC was PCM-based; if the AIFC used a lossy codec (A-law, mu-law, IMA), the WAV will be the decoded PCM but the lossy step that produced the AIFC is permanent.
