    \title{Descriptor Driven Concatenative Synthesis Tool}
    \subtitle{\LARGE{Abstract Draft}}
    \author{Sam Perry}
    \date{}
    \maketitle
    \begin{abstract} 
    A command-line tool is proposed for the exploration of a new form of audio
    synthesis known as ``concatenative-synthesis'': A form of synthesis that uses
    perceptual audio analyses to arrange small segments of audio based on their
    characteristics.  The tool is designed to synthesise representations of an
    input sound using a database of source sounds. This involves the
    segmentation and analysis of both the input sound and database, matching of
    input segments to their closest segment from the database, and the
    re-synthesis of the closest matches from the database to produce the final
    result.\\
    The aim was to produce a tool capable of generating high quality sonic
    representations of an input, and to present a variety of examples that
    demonstrated the breadth of possibilities that this style of synthesis has
    to offer. There are a number of other projects that use this form of
    synthesis, however this project aims primarily to explore the further
    potential offered through the offline processing of large databases, of
    which considerably less research exists.\\
    Overall, results demonstrate the wide variety of sounds that can be
    produced using this method of synthesis. A number of technical issues were
    outlined that impeded the overall quality of results and efficiency of the
    software. However, the project clearly demonstrates the strong potential
    for this type synthesis to be used for creative purposes.

    \title{Independant Project\\Descriptor Driven Concatenative Synthesis Tool}
    \subtitle{\LARGE{Results Analysis}}
    \author{Sam Perry\\U1265119}
    \date{}
    \maketitle
    \section{Overview}
    This document aims to provide reasoning for the sonic characteristics of
    the audio produced in this project. Samples have been provided to
    demonstrate the breadth of possibilities for the concatenator script.
    Samples use a range of databases of varying sizes and aim to show both the
    strengths of this script and areas that could be developed further to
    improve results.
    \section{Sample Analysis}
    Samples are organized in folder named by their source\char`_target databases.
    \subsection{Guitar\char`_Guitar}
    Source Database: University of Iowa Sample Database - Guitar\\
    Target Database: David Chaplin's Guitar Samples\\
    These samples were generated with the intention of matching the clean
    guitar to a clean guitar database. It was thought that in an ideal
    situation this would produce a result similar to the original but with the
    tonal qualities of the sampled guitar. The result is far from this as the
    current descriptors do not provide a description that is sufficiently
    accurate. However, The General contour of the clean guitar can be heard and
    the ``plucky'' qualities of the sampled database are definitely present.
    \subsection{Guitar\char`_Violin}
    Source Database: University of Iowa Sample Database - Violin\\
    Target Database: David Chaplin's Guitar Samples\\
    Overall, result produced were smooth and for the majority of the samples
    used, are similar to that of a stringed instrument. The occasional glitch
    detracts from this and there are a number of reason for these small glitches.
    At around 3 seconds, a high pitched screech can be heard that does not fit
    in with it's neighbouring samples. When comparing this to the event in the
    original file, it can be seen that this is a sharp decay and pause that is
    analysed as an inharmonic signal with very different characteristics to
    it's neighbouring samples. Use of a viterbi algorithm would most likely
    help to minimise these types of error, alongside better handling of
    inharmonic samples.
    \subsection{Guitar\char`_Xylophone}
    Source Database: University of Iowa Sample Database - Xylophone\\
    Target Database: David Chaplin's Guitar Samples\\
    This example demonstrated interesting timbral qualities due to the rich
    variety of harmonic percussive sounds in the Xylophone database. By
    matching primarily on pitch and spectral content, a mixture of transient
    grains are concatenated with reasonable results.
    \subsection{Multiple\char`_Vocal}
    Source Database: Alex Harker Vocal Database\\
    Target Database: David Chaplin's Guitar Samples, Rayman Spoken Word
    Database\\
    This database provided interesting results in terms of timbre as the outcome
    is a mixture of vocal techniques. This sounds entirely synthetic which is
    expected, and there are glitches as with all the results. However, the results
    appear to be perceptually related to both the source and target databases.
    Vocal qualities can be heard through the clicks, hums and other elements
    that are combined. Continuity between grains is a significant problem as
    selected grains do not flow in the same way that natural vocals might.
    Again, comparing matches in a post matching process such as a viterbi
    decoding stage would help to counter this effect.
    A stretched version of Clean\char`_1 was included to demonstrate the results of
    setting different values for matching and synthesis overlaps. By setting the
    matching overlap to 8 and the synthesis overlap to 4, the synthesis was
    stretched by a factor of 2.
    \subsection{Spoken\char`_Xylophone}
    Source Database: University of Iowa Sample Database - Xylophone\\
    Target Database: Rayman Spoken Word Database\\
    This example was generated during development and has been included as it
    demonstrated an effective mix between the qualities of the two databases.
    The pitch and envelope of the vocals can be heard whilst the timbre of the
    Xylophone database is also clear. Glitchy pitch shifted grains can be heard
    in the background as this was a problem with the project at the time and
    has since been fixed by altering handling of inharmonic grains in the
    picth shifter.
    \subsection{Vocal\char`_Marimba}
    Source Database: University of Iowa Sample Database - Xylophone\\
    Target Database: Danny Darko Acapella Vocals Sample\\
    This sample highlights a number of problems with the current implementation
    of this algorithm.
    There is a considerable amount of noise as a result of the intensity
    scaling. This has increased quite sounds with low signal/noise ratios and
    as a result this can be heard clearly in the results.
    The clicks produced through poor performance of the pitch shifter have also
    degraded the signal during synthesis. Replacing the pitch shifter with a
    more effective algorithm would most likely improve results.
    \subsection{Vocal\char`_Wind}
    Source Database: University of Iowa Sample Database - Xylophone\\
    Target Database: Danny Darko Acapella Vocals Sample\\
    These examples are significantly less satisfying. Inharmonic noise from the
    player taking breaths mixes poorly to generated a layer of breathy noise.
    This is further emphasized by the pitch shifting of this noise. This
    demonstrates an inherent problem with pitch shifting technique used to
    transform grains, in that inharmonic audio is also transformed. This would
    be greatly improved with the use of a better pitch shifting algorithm.
    \section{Overall Performance}
    Overall, it was difficult to generate results of a high quality due to the
    current issues with the algorithm used. During development, much time was
    spent increasing the speed of the algorithm to make it possible to create a
    high enough quantity of results. On reflection, spending more time on
    improving output quality may have yielded better results. However,
    overall it is clear that this style of synthesis shows real potential for
    generating a wide range of interesting sound and as a prototype or proof of
    concept, the script achieves a reasonable quality of result.

 \textbf{\huge Questionnaire on the effects of electronic processing in music}
 \end{center}\vskip1em
 \noindent This survey forms part of a study into the effects of audio
 processing on perceptions of musical quality.  You will be presented with a
 selection of 40 audio examples. For each example, you will be asked to provide
 a rating for the example's musical quality. This refers to your opinion on the
 overall skill of the performer/composers. You will also be asked to provide a
 rating for the ``artificialness'' of the example. This refers to the amount of
 influence you believe electronic processing has had on the creation and
 production of this piece. Finally, you are asked to provide a rating for how
 much you like the example. This is purely subject to personal preference.  A
 section is also provided at the bottom of the questionnaire for any further
 comments on examples or the questionnaire in general. Thank you for your
 participation.
