摘要： The present synthesizer generates an underlying spectrum, pitch and loudness for a sound to be synthesized, and then combines the underlying spectrum, pitch and loudness with stored Spectral, Pitch, and Loudness Fluctuations and noise elements. The input to the synthesizer is typically a MIDI stream. A MIDI preprocess block processes the MIDI input and generates the signals needed by the synthesizer to generate output sound phrases. The synthesizer comprises a harmonic synthesizer block (which generates an output representing the tonal audio portion of the output sound), an Underlying Spectrum, Pitch, and Loudness (which takes pitch and loudness and uses stored algorithms to generate the slowly varying portion of the output sound) and a Spectral, Pitch, and Loudness Fluctuation portion (which generates the quickly varying portion of the output sound by selecting and combining Spectral, Pitch, and Loudness Fluctuation segments stored in a database). A specialized analysis process is used to derive the formulas used by the Underlying Spectrum, Pitch, and Loudness and to generate and store the Spectral, Pitch, and Loudness Fluctuation segments stored in the database.

摘要： The present invention is a musical synthesizer that can respond to a pitch wheel control by generating realistic slide-step-slide and slide-step portamento pitch curves. The musical synthesizer responds to a pitch wheel control in a context sensitive manner. When a first note-on occurs the pitch wheel behaves in the standard fashion. However, when a second-note on occurs, if the pitch wheel is still being held after the second note-on then the effects of the pitch wheel are disabled. The result is a clean slide-step portamento curve. In addition, the effects of the pitch wheel are delayed slightly relative to the raw pitch wheel signal. The result is that if the pitch wheel is released slightly before a second note-on occurs then the delayed pitch wheel signal will still be at substantially the previous held value when the second note-on occurs. The result is a clean slide-step portamento curve. In another embodiment when a second-note on occurs, if the pitch wheel is still being held after the second note-on, effects of the pitch wheel are disabled and, in addition, the pitch curve is forced to make a small ramp beginning towards the pitch of the second note-on. The result is a clean slide-step-slide portamento curve.

摘要： A hearing aid has a built in or internal test tone generator for providing test tones and noise for diagnostic tests to a user through the receiver of the hearing aid. Alternatively an external test tone generator may be coupled to the hearing aid and selectively coupled to the receiver of the hearing aid for the diagnostic tests. A memory internal to the hearing aid may store real world sounds for diagnostic tests to simulate actual usage of the hearing aid.

摘要： A detachable digital binaural processing hearing aid comprised of a digital signal processor (DSP), two microphones, two receivers, a bi-directional communications link between each microphone/receiver and the digital signal processor, an analog-to-digital converter, and a digital-to-analog converter. In one embodiment of the present invention, the user has the option of disabling the digital signal processor by either physically removing an external digital processing unit or by disabling a digital processor to permit an analog processor to provide audio enhancement. The user is also given the option of selecting from a variety of digital filters/compressors that generate binaural signals that are sent to both ears of the user. In a second embodiment, each hearing element comprises a digital signal processor and a communication link to the other hearing element. Two examples of the communication link are an electrical wire connecting the two hearing elements and a electromagnetic transceiving system where each hearing element has a transceiver that transmits a signal representing the sound at one ear of the user and receives a signal representing the sound at the other ear of the user.

摘要： A parametric signal modeling musical tone synthesizer utilizes a multidimensional filter coefficient space consisting of many sets of filter coefficients to model an instrument. These sets are smoothly interpolated over pitch, intensity, and time. The filter excitation for a particular note is derived from a collection of single period excitations, which form a multidimensional excitation space, which is also smoothly interpolated over pitch, intensity and time. The synthesizer includes effective modeling of attacks of tones, and the noise component of a tone is modelled separately from the pitched component. The input control signals may include initial pitch and intensity, or the intensity may be time-varying. A variety of instruments may be specified.

摘要： In a large exhaust duct from a lean burn combustion source, such as a boiler, diesel engine or gas turbine, multiple injectors can be used to inject a reagent, such as an aqueous solution of urea or ammonia, into the exhaust for use in the catalytic reduction of NOx in a process known in the art as selective catalytic reduction (SCR). When operating at low injection rates, such as during low combustor loads, the injectors are operated individually for short periods of time in a sequential manner.

Each of the digital signal processing means is designed to provide optimal results in a particular listening environment.
