Abstract [en]
Since the usage of qualitative research methods in the field of pitch-shifting are not to be found by the author, our audible perception of different pitch-shifters haven’t been well investigated. The aim of this essay is to investigate the perceived audible differences in timbre between different pitch-shifting algorithms, and to develop a descriptive language to be used when evaluating such. This was done by using a method, inspired by ADAM, consisting of the two main parts of attribute elicitation, using listening tests, and the development of common attributes and scales by a group discussion. The tests resulted in approximately 50 descriptive attributes, and 20 words describing some perceived defects in the sound, caused by the pitch-shifters. After the group discussion 5 scales, uni- and bipolar, were created by the attributes. The conclusion is that it is possible to develop a descriptive language for the evaluation of pitch-shifting algorithms, although some further research is required to establish such a language.
