AIFC to WAV Converter

Convert AIFC to WAV Online

AIFC (also written AIFF-C) is the extended form of Apple's AIFF audio format — most often it's what macOS writes when you import a CD or record with QuickTime, and some apps and players choke on the extension even though the audio inside is fine. This converter reads the AIFC container and writes a standard RIFF WAV that opens cleanly in Windows, DAWs, editors, and just about any player. WAV is uncompressed PCM, so if your AIFC holds uncompressed audio the result is a bit-for-bit copy of the samples in a more portable wrapper.

How to Convert AIFC to WAV

1. Upload Your AIFC File: Drag and drop your .aifc file onto the page or click "+ Add Files" to browse. You can queue several files and convert them with the same settings.
2. Set Audio Channel and Sample Rate: Leave both on "Original" for an exact copy, or use the Audio Channel dropdown to fold stereo down to mono and the Audio Sample Rate dropdown to resample (for example, down to 44.1 kHz).
3. Pick the WAV Codec (Optional): Expand the options to choose the Audio Codec — the default PCM 16-bit gives you a standard CD-quality WAV; pick PCM 24-bit or 32-bit for more headroom, or trim the clip with the Trim control.
4. Convert and Download: Click "Convert" and download your WAV. No sign-up, no watermark.

Frequently Asked Questions

Will converting AIFC to WAV reduce the audio quality?

If your AIFC stores uncompressed PCM — which is the case for most files macOS generates, including CD imports — the conversion is lossless and the WAV holds the same samples. If the AIFC was encoded with a lossy codec such as μ-law or IMA ADPCM, decoding it to PCM WAV makes the file portable but cannot restore detail that the original compression discarded.

Why won't my AIFC file open in some apps when it plays fine on my Mac?

AIFC is tightly tied to Apple's ecosystem, so QuickTime, Music, and Finder handle it natively while many Windows players, web players, and some DAWs don't register the .aifc extension. Converting to WAV gives you a RIFF file that those programs recognize without any extra codec.

What sample rate and bit depth will the WAV use?

By default the converter preserves the source — a typical AIFF/AIFC ripped from a CD is 44.1 kHz, 16-bit, and that carries straight through to the WAV. You can override both: the Audio Sample Rate dropdown resamples, and the Audio Codec option lets you write 16-, 24-, or 32-bit PCM.

Is a WAV bigger than the AIFC it came from?

If the AIFC was already uncompressed PCM, the WAV is roughly the same size — both store raw samples, so a stereo 44.1 kHz/16-bit minute is about 10 MB either way. If the AIFC used a compression codec, the decoded WAV will be noticeably larger because it expands back to full PCM. Keep in mind WAV files are capped at 4 GiB by the format's 32-bit size field.

Are my files private when I convert them here?

Yes. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public. In our testing, a 3-minute stereo AIFF-C ripped from a CD converted to a 16-bit WAV of about 31 MB with the samples unchanged.

Need the AIFF extension instead of AIFC, or want to go the other way? See WAV to AIFF for the reverse, or AIFF to WAV if your file uses the plain .aiff name.
