Safety guards and vacuum extraction is in place on all key machinery.Health and safety briefings take place with all employees on a regular basis.Looking after them is part of our journey. As part of the Auden team, our craftsmen share our desire to build great guitars. We are sure that our workshop is at the forefront of employee welfare and we are committed to continuous improvement in this area. When you buy an Auden guitar you can be sure that high standards of Health & Safety management are in place at every stage in the process. As part of our journey with Auden Guitars we were shocked to see that many international guitar brands seem to ignore this. Cutting and sanding machines, hardwood dust and lacquer spraying all have a risk to human health. The process of building any guitar contains many hazards. This work has implications for research in musical timbre, automatic media annotation, human talker identification, and computational auditory scene analysis.A new standard for guitar building Building Guitars The computer model's performance is robust with regard to the variations of reverberation and ambient noise (although not with regard to competing sound sources) in commercial compact disc recordings, and the system performs better than three out of fourteen skilled human listeners on a forced-choice classification task. The performance of the model is compared directly to that of skilled human listeners, using both isolated musical tones and excerpts from compact disc recordings as test stimuli. It explicitly extracts salient acoustic features and uses a novel improvisational taxonomic architecture (based on simple statistical pattern-recognition techniques) to classify the sound source. The model is based on current models of signal processing in the human auditory system. A computer model of the recognition process is developed that is capable of "listening" to a recording of a musical instrument and classifying the instrument as one of 25 possibilities. Previous research on the perception and production of orchestral instrument sounds is reviewed from a vantage point based on the excitation and resonance structure of the sound-production process, revealing a set of perceptually salient acoustic features. In order to explore the process, attention is restricted to isolated sounds produced by a small class of sound sources, the non-percussive orchestral musical instruments. This thesis proposes a theory of sound-source recognition, casting recognition as a process of gathering information to enable the listener to make inferences about objects in the environment or to predict their behavior. Robust listening requires extensive contextual knowledge, but the potential contribution of sound-source recognition to the process of auditory scene analysis has largely been neglected by researchers building computational models of the scene analysis process. In contrast, computer systems designed to recognize sound sources function precariously, breaking down whenever the target sound is degraded by reverberation, noise, or competing sounds. The ability of a normal human listener to recognize objects in the environment from only the sounds they produce is extraordinarily robust with regard to characteristics of the acoustic environment and of other competing sound sources.
