AIF files are audio samples, while Kontakt uses NKI files to describe playable sampler instruments. Convert an AIF to NKI when you need to load a sample as an instrument in Kontakt; the result is not simply the same audio in a different container.
What the AIF format is
AIF (also called AIFF) is an audio file format used for storing digital sound, commonly as uncompressed PCM audio. Digital audio workstations, audio editors, and recording tools create AIF files, which are often used as source samples for editing, mixing, or sampling.
What the NKI format is
NKI is Native Instruments Kontakt’s instrument format. It stores instrument settings such as sample zones, key ranges, and playback parameters; it may reference audio samples stored separately. Use NKI when you want to load a sample as a playable instrument in Kontakt. An NKI file generally requires Kontakt or a compatible Kontakt-based product.
How to convert AIF to NKI
Online on 101convert.com
- Open the AIF-to-NKI converter on 101convert.com and upload your AIF file or files.
- Choose NKI as the output format and start the conversion.
- Download the converted NKI file when processing finishes.
Multiple files can be converted in one batch. The page shows a per-file size limit.
Offline with desktop software
Native Instruments Kontakt can create an NKI from an AIF. Open Kontakt, create an empty instrument, and open its Mapping Editor. Drag the AIF into the editor, assign its root key and key range, then use File → Save as to save the instrument as an NKI. Menu names can vary by Kontakt version. Choose a save option that includes the sample if you need to move or share the instrument; a patch-only save can leave the NKI dependent on the original AIF file. Full Kontakt is needed to author and save user instruments; Kontakt Player is not a general-purpose NKI editor.
Quality and compatibility
NKI describes an instrument rather than encoding audio. The AIF sample’s audio quality is unchanged if it is referenced without resampling, but playback depends on the NKI’s mapping and instrument settings. Keep the source AIF with the NKI unless the samples were packaged into the saved instrument. Kontakt version compatibility can also affect whether an NKI loads correctly.
