摘要： A system and method for audio synthesizer utilizing frequency aperture cells (FAC) and frequency aperture arrays (FAA). In accordance with an embodiment, an audio processing system can be provided for the transformation of audio-band frequencies for musical and other purposes. In accordance with an embodiment, a single stream of mono, stereo, or multi-channel monophonic audio can be transformed into polyphonic music, based on a desired target musical note or set of multiple notes. At its core, the system utilizes an input waveform(s) (which can be either file-based or streamed) which is then fed into an array of filters, which are themselves optionally modulated, to generate a new synthesized audio output.

摘要： A string signal generator generates a string signal representing vibration of a string corresponding to a specified pitch in response to a note-on instruction such that the string signal rises and then attenuates in response to a note-off instruction. The string signal generator distributes the generated string signal to a plurality of loop circuits of a string resonance simulator. The plurality of the loop circuits correspond to a plurality of pitches and circulate resonant signals of the corresponding pitches, each loop circuit having a delay element for delaying the resonant signal by a time depending on the corresponding pitch, and an attenuation element for variably attenuating the resonant signal according to an attenuation coefficient. A controller respectively provides attenuation coefficients to the attenuation elements in the plurality of the loop circuits based on the note-on instruction, the note-off instruction, a damper-pedal-on instruction, and a damper-pedal-off instruction.

摘要： A musical tone generation apparatus is basically configured by a main sound source device installing an extension board. Herein, the main sound source device is configured by a CPU, memories, operators, a music synthesizer, a mixer, an effector and a sound system, while the extension board is configured by fabricating a CPU (or sequencer), memories and a music synthesizer (or effector). When the extension board is installed in the main sound source device, function setting data regarding new functions installed on the extension board is automatically transferred to the main sound source device so that a user is capable of adequately setting and controlling the new functions by using the operators. If the extension board corresponds to a tone color extension board that provides extended tone colors which differ from preset tone colors being installed in the main sound source device in advance, the main sound source device is capable of generating musical tones using the extended tone colors. In that case, it is possible for the sequencer to enable reproduction of a specific sound pattern such as an arpeggio and a phrase to be suited to the extended tone color(s). If the extension board corresponds to an extended effect board that provides extended effects such as harmony, reverb, chorus and echo, the main sound source device is capable of adequately imparting them to musical tones or other sounds.
摘要翻译：音乐发生装置基本上由安装扩展板的主声源装置构成。这里，主声源装置由CPU，存储器，操作器，音乐合成器，混音器，效应器和声音系统构成，而扩展板通过制造CPU（或音序器），存储器和音乐合成器（或效应器）。当扩展板安装在主声源设备中时，关于安装在扩展板上的新功能的功能设置数据被自动传送到主声源设备，使得用户能够通过使用主音源设备来适当地设置和控制新功能运营商。如果扩展板对应于预先提供与主声源装置中安装的预设音色不同的扩展音色的音色扩展板，则主声源装置能够使用扩展音色产生乐音。在这种情况下，定序器有可能使诸如琶音和短语之类的特定声音模式能够再现适合于扩展音色。如果扩展板对应于延伸效果板，其提供诸如和声，混响，合唱和回声的延长效果，则主声源装置能够充分地赋予它们音乐或其他声音。

摘要： The invention relates to methods for use in a wavetable based sound synthesis, wherein a first processor stores wavetable data and wherein a second processor generates an output audio signal frame-by-frame based on samples of the wavetable data. One method comprises at the first processor selecting samples of the stored wavetable data, which are expected to be required at the most at the second processor for generating a next output audio frame. The selection is based on a model of a pitch-shift evolution during a single frame and on the number of samples which have been used so far by the second processor. The selected samples are made available to the second processor. Another method allows the second processor to make use of the provided samples. The invention relates equally to corresponding processors, to a corresponding wavetable based sound synthesis system, to a corresponding device and to corresponding software program products.
