Euclidean Algorithm for Sound Generation

Euclidean algorithm is known by humanity for more than two thousand years. During this period many applications for it were found, covering different disciplines and music is one of those. Such algorithm application in music first appeared in 2005 when researchers found a correlation between world music rhythm and the Euclidean algorithm result, defining Euclidean rhythms as the concept.In the modern world, music could be created using many approaches. The first one being the simple analogue, the analogue signal is just a sound wave that emitted due to vibration of a certain medium, the one that is being recorded onto a computer hard drive or other digital storage called digital and has methods of digital signal processing applied. Having the ability to convert the analogue signal or create and modulate digital sounds creates a lot of possibilities for sound design and production, where sonic characteristics were never accessible because of limitations in sound development by the analogue devices or instruments, nowadays become true. Sound generation process, which usually consists of modulating waveform and frequency and can be influenced by many factors like oscillation, FX pipeline and so on. The programs that influence synthesised or recorded signal called VST plugins and they are utilising the concepts of digital signal processing.This paper aims to research the possible application of Euclidean rhythms and integrate those in the sound generation process by creating a VST plugin that oscillates incoming signal with one of the four basic wave shapes in order to achieve unique sonic qualities. The varying function allows modulation with one out of four basic wave shapes such as sine, triangle, square and sawtooth, depending on the value received from the Euclidean rhythm generator, switching modulating functions introduces subharmonics, with the resulting richer and tighter sound which could be seen on the spectrograms provided in the publication.

The smartphone generation of community radio listeners: Is FM sustainable?

This article examines the current environment of audio transmission services in the UK with particular regard to the community radio sector. Community radio stations in the UK are having to consider the extent to which their audiences choose to listen on an FM analogue signal and whether this is sustainable for them. The number of new platforms that a listener is using to access audio programming now includes DAB, SSDAB, TV carriers and online services. There are also developments to the actual receivers that may be used, in particular the use of smartphones to listen via online Wi-Fi or 4G. Currently there are no plans for an FM turn off in the UK and a hybrid system of transmission and reception is the most likely outcome for the foreseeable future. The consequences of this environment for the broadcasters, the listeners and the audio content are discussed in turn. A sample group of twelve community radio stations have been studied to assess current practices. This group are the remaining stations from the original Access Pilot community radio stations that went on air in 2002 and so are the oldest and most established of the UK stations. This article provides baseline definitions where relevant and uses recent data from national audience research, regulatory and other bodies to assess what people are listening to and how, along with examples from public service and commercial radio, as well as community radio.
