About AIFF to SMP Conversion

AIFF (introduced 1988) and SMP are both audio formats, but they differ in important ways. AIFF is Apple's uncompressed audio format — equivalent to WAV in quality. SMP is a widely used file format.

When you convert AIFF to SMP, the goal is to convert between formats quickly. Converting AIFF to SMP maintains high quality with CocoConvert's optimised encoder settings. Understanding these technical differences helps you choose the right format for your workflow.

Your AIFF file is decoded and re-encoded as SMP. The conversion involves 4 steps: (1) your aiff file is uploaded and validated, (2) the file is decoded (parsed into its raw data), (3) the data is re-encoded in smp format, (4) the converted file is ready for download.

CocoConvert's converter handles the entire pipeline server-side using FFmpeg, Sharp, and qpdf — battle-tested libraries used by streaming platforms and enterprise tools. Files are encrypted in transit and deleted within 24 hours.
