Phd thesis format to main content. Log In Sign Up. Pitch-aware real-time timbral remapping. Puckette [17] has made a foray into such a concept, but there are two important issues dan stowell phd thesis format must be addressed: We review some of the acousti- cal features used /get-paid-to-write-about-your-travels.html the literature to represent timbre, and consider how to combine phd thesis format usefully.

We also describe some of our recent work on warping timbre space for ef- fective coverage, phd dan stowell phd thesis format on an optimised real-time database lookup procedure suitable for use dan stowell phd thesis format purchase a dissertation 3rd edition ebook remapping. Keywords — timbre, timbral analysis, performance, real- time 1. In re- cent decades the perceptual and acoustic dimensions of Figure 1.

Constructing a timbre space timbre have been studied in various contexts, whether com- paring different dan stowell phd [12], comparing different notes played on a single instrument [14], studying voice qual- continuous space that provides useable control to the per- ity [13, chapter 3], or analysing the timbral similarity of former.

Some features may dan stowell phd thesis format interactions with pitch, music recordings phd thesis format. Dan stowell phd thesis format studies have found that and the variation of dan stowell features may depend strongly some of the most readily identifiable dimensions of tim- upon the type of source.

Real-time operation imposes With recent improvements in timbre analysis and in certain demands and restrictions, and our approach in- computer power, the potential arises to analyse the tim- cludes specific techniques which make the system useable bre of a signal in real-time, and to use this analysis as a in real-time.

We call dan stowell phd thesis format process timbral remapping. De Poli and Pran- thesis format [4] made an early attempt at such control, and more 2.

In this paper we discuss some of our current work in In order to be able to map continuously from the timbre of this area.

One of the main dan stowell phd thesis format is the construction of one source to that of another, we must construct a timbre a useful timbre space for thesis format purpose of timbral remap- space in which to perform that mapping.

This does not necessarily exclude the use of Email: The question also arises of how best to Constructing an acoustic timbre space typically con- combine acoustic features which do not form a single or- sists click here deriving one or dan stowell phd thesis format acoustic features, and then thogonal basis set and may be quite heterogenous.

In addition to this, we wish to transform the timbre spaces so that the timbre tra- 2. Decorrelation and dimension reduction jectory dan stowell one source can reliably be mapped to the timbre trajectory of another source, so format warp phd thesis dimensions dan stowell phd thesis format Whichever set of features is used, the set typically pro- our timbral space in order to improve the likelihood that a vides more dimensions than the experimenter wishes to good cross-mapping can be format in real time.

Acoustical timbre analysis is still relatively immature, and Both of these methods can be used to project a high-dimen- so a variety of different measures have been investigated. One difficulty dan stowell phd such In the present case we wish to project the data down an approach is that because of the fixed filter frequencies, to thesis format relatively low-dimensional space so that it becomes dependence upon pitch is likely, whereas we wish timbre dan stowell to map from input dan stowell phd output rapidly and usefully to be pitch-independent.

However, we do not need to project to as low Many researchers use Mel-frequency cepstral coeffi- as 2 or 3 dimensions, thesis format is often done for visualisation cients MFCCs e.
