A novel and simple approach to analysis-synthesis, called ‘Residuals using Simple Separation’ (RUSS) is presented, which enables sophisticated manipulation of sounds in an intuitive working environment built from readily available audio processing tools. The aim of the research was to enable audio practitioners to work with sampled sound without requiring detailed engineering knowledge, the ability to understand complex mathematical concepts, or expensive signal processing. This paper describes how this goal has been achieved using a simple, ‘two component’, model for both the decomposition and subsequent synthesis of sound. The initial decomposition process shows how almost any sample can be simply converted into a ‘harmonic’ or ‘tonal’ portion containing the majority of the pitched parts of the sound, and a ‘residual’ or ‘noise’ portion which contains the remainder of the spectral content. Once a sound has been separated into these two easily-comprehended orthogonal parts, then rapid changes can be readily made to many normally inaccessible features of sampled sounds, using widely available conventional sound synthesis functionality (which would be unable to achieve these types of modification without using the techniques described). As well as describing the required decomposition processes, and providing many examples of synthesized sounds produced using the technique described, this paper also details the minor enabling additions that need to be added to conventional sound synthesis in order to make working with samples easy and obvious. The end result is that many of the practical barriers to the creative and innovative use of sampled sounds are significantly reduced.

Recently, hybrid format audio technologies have been proposed as audio systems of new media such as broadcasting, virtual reality and cinema. However, when playing hybrid-format audio with multi-channel loudspeakers, rendering the object sound source by panning is no different from pre-rendered channel-based audio. Therefore, it is necessary to find a way to immersive reproduce the object sound source. We propose a method to maximize the immersiveness by hybrid playback of loudspeakers and headphone. It is verified through comparative evaluation that this method can obtain a meaningful performance improvement over the loudspeaker only method and also proved that it is possible to provide more immersive sound through application of hybrid playback in VR Attraction system.

This paper describes an easily-run test that allows the short-term peak power and maximum SPL capabilities of amplifiers, electronic systems, loudspeakers, and sound reinforcement systems to be evaluated over the complete audio range. It is based on the use of a series of eleven octave-bandwidth tone-burst wave files at standard octave-center frequencies of 16 Hz to 16 kHz. The tone burst wave-shapes are very similar to those found in typical music program material. For a specific peak power or peak SPL frequency-response test, each tone burst is sequentially applied to the device under test and the maximum output is assessed at each frequency either subjectively or objectively. This differs from the author’s past work on the same topic that essentially accomplished the same test using a series of 31 third-octave bandwidth tone bursts. This new proposed test method uses far-fewer tone bursts and as a result the test is much easier and quicker to accomplish.
