Description
BACKGROUND OF THE INVENTION
The present invention relates to electronic means for music generation and more particularly has as its object the provision of such instrument with a sound engine comprising an architecture enabling the application of thousands of stored unitsof music digital data to rapid production of analog speaker-driving forms, utilizing practical solid state circuit means.
The invention is described below with reference to electronic piano usage, but is also usable in a number of other electronic musical instrument roles to provide, singly or combined, the sounds of a variety of instrument, elements of human voiceand other sound sources and in analogous instrument contexts not involving music or voice, but involving comparably varying waveform data.
Multiple Partial (Fourier) Synthesis is a technique well known in engineering practice. Any arbitrary periodic waveform (e.g., musical instruments' sound) may be reproduced by summing up a series of sine waves of appropriately determinedfrequencies, amplitudes, and relative phases. This technique allows great flexibility, much more so than subtractive synthesis (which starts out with a complex waveform and filters out unwanted spectral content) or wave-table synthesis (which can onlyreproduce whatever is in the table).
It is the object of the present invention to establish effective instrumentation using Fourier synthesis.
SUMMARY OF THE INVENTION
The musical apparatus of the invention inputs a stream of digital signals which represent a sequence of audio notes to be ultimately produced. The apparatus creates a sequential list of partials and impresses time-varying amplitude envelopes onthem, such that the sequential list completely characterizes the desired audio signal. A multiple partial synthesis, sometimes referred to as a Fourier Synthesis, is formed.
Each partial from the sequential list is digitally generated by stepping through a ROM containing a single cycle forming the frequency of that partial and combining it with the amplitude envelope for that partial resulting in a signal with thedesired frequency, amplitude, duration and attack and decay rates. All the partials are summed into a digital data stream which is converted to an analog form, filtered and made available for use, for example by an audio amplifier and speakers producingsound.
With reference to the preferred embodiment a sine wave is digitally stored and sensed at an appropriate rate of change of phase angle per sample frequency ...

20: The Younger Generation Enjoys The Rich Sound Of Vinyl On The New Audio Turntables
2009-08-29 00:00:00The CDs out there have a pristine sound, but records provide a better sound. Younger kids like the cover art on the records as well, according to James Patterson, age 17, who doesn't even remember when they LPs were popular in the past. He found some old LPs up in the attic at his grandparents home by the Beatles and the Rolling Stones, then his uncle grabbed him a player on eBay and he know displays it in his room.<br /><br />Replica turntable systems are available from various manufacturers. They look like the past machines but have today's technology used in them. A few top manufacturers include Memorex, jWin, Teac, and Crosley. Various functions are included, which includes USB connections, stacking up multiple LPs, and even recording from the LPs to CD as well.<br /><br />Raman of Classic Buys says that Nostalgia turntables are among the best seller audio electronics during gift giving Christmas season. Nostalgia turntables from popular brands like Crosley, Teac, Memorex and Thomas Pacconi are the top picks.<br /><br />Shoppers are looking for the best brands and great features when they purchase audio turntables today according to The Magma Group president. They prefer to go with systems that are four in one, playing the radio, ...
