The objective of this paper is to investigate the accuracy of the process known as Automatic Feature Identification (AFI), when attempting to morph two or more tones together to create a `mongrel' sound in the process known as timbre morphing. Morphing is examined using the processes endemic to the morphing package called Mongrel which concentrates on AFI and enhanced feature identification. The automatic processes are examined, and the resulting morphs from the process are tested on a sample base of musical and non-musically trained listeners to check for accuracy of representation in the sounds derived.
