How do I convert M4A files to IFF format?

Upload your M4A file, select IFF (8SVX) as the target, choose sample rate and bit depth (e.g., 44100 Hz / 16-bit), then click Convert. Our tool decodes M4A's AAC or ALAC audio to PCM and wraps it in an IFF container. Download the resulting .IFF file within seconds.

Why should I convert M4A to IFF instead of using MP3?

IFF/8SVX is an uncompressed PCM format used by Amiga trackers and classic audio software. Unlike M4A's lossy AAC, IFF preserves every sample exactly, making it ideal for chiptune production, retro game audio, and hardware that only reads 8SVX. File size is larger, but compatibility and fidelity are unmatched.

How does the M4A to IFF conversion handle audio quality?

When converting M4A to IFF, the audio is decoded to PCM at its original sample rate and bit depth. If the M4A uses lossy AAC, the compression artifacts are already baked in; converting to IFF won't restore lost frequencies but will preserve the decoded data losslessly. For ALAC (lossless M4A), the conversion is bit-perfect. The resulting IFF file stores audio as uncompressed 8-bit or 16-bit signed samples, exactly matching the source parameters you select.
