چکیده

We have developed an alternate method of representing harmonic amplitude envelopes of musical instrument sounds using principal component analysis. Statistical analysis reveals considerable correlation between the harmonic amplitude values at different time positions in the envelopes. This correlation is exploited in order to reduce the dimensionality of envelope specification. It was found that two or three parameters provide a reasonable approximation to the different harmonic envelope curves present in musical instrument sounds. T he representation is suited for the development of high-level control mechanisms for manipulating the timbre of resynthesized harmonic sounds.

Discrimination of Golab apple storage time using acoustic impulse response and LDA and QDA discriminant analysis techniques

ABSTRACT- Firmness is one of the most important quality indicators for apple fruits, which is highly correlated with the storage time. The acoustic impulse response technique is one of the most commonly used nondestructive detection methods for evaluating apple firmness. This paper presents a non-destructive method for classification of Iranian apple (Malus domestica Borkh. cv. Golab) according...

There’s More to Groove than Bass in Electronic Dance Music: Why Some People Won’t Dance to Techno

The purpose of this study was to explore the relationship between audio descriptors for groove-based electronic dance music (EDM) and raters' perceived cognitive, affective, and psychomotor responses. From 198 musical excerpts (length: 15 sec.) representing 11 subgenres of EDM, 19 low-level audio feature descriptors were extracted. A principal component analysis of the feature vectors indicated...

Feature-Based Synthesis: Mapping Acoustic and Perceptual Features onto Synthesis Parameters

Substantial progress has been made recently in finding acoustic features that describe perceptually relevant aspects of sound. This paper presents a general framework for synthesizing audio manifesting arbitrary sets of quantifiable acoustic features of the sort used in music information retrieval and other sound analysis applications. The methods described have broad applications to the synthe...

Affective Sound Synthesis: Considerations in Designing Emotionally‐Engaging Timbres for Computer Music

In this paper, we examine the essential role of instrument timbre in communicating and eliciting emotion in music, and consider how this knowledge can inform the design process of sound synthesis towards achieving maximum expression. In the composition and performance of acoustic music, timbres are carefully chosen to capture and communicate the emotional undercurrent of the musical material. I...
