Provided is an information-providing system whereby a variety of information can be provided using a sound to a portable terminal device used by a user. The information-providing system includes a sound output device outputting, as a sound wave, identifying information modulated into a sound signal, an identifying-information resolution server, connected to an information-communication network, for identifying, based on the identifying information, address information for accessing a content server connected to an information-communication network; and a portable terminal device including a sound receiving section for receiving the sound wave outputted by the sound-emitting device, a demodulating section for demodulating the identifying information from the received sound wave, a resolution section for sending the demodulated identifying information to the identifying-information resolution server and acquiring the address information, and an accessing section for accessing the content server using the acquired address information.

Provided are a musical performance-related information output device and a musical performance system capable of superimposing musical performance-related information on an audio signal without damaging the general versatility of the audio signal. The musical performance-related information output device includes a musical performance-related information acquiring section that is adapted to acquire musical performance-related information related to a musical performance of a performer, a superimposing section that is adapted to superimpose the musical performance-related information on an analog audio signal such that a modulated component of the musical performance-related information is included in a band higher than the frequency component of the analog audio signal generated in accordance with the musical performance manipulation of the performer, and an output section that outputs the analog audio signal on which the superimposing section superimposes the musical performance-related information.

An audio signal processing device includes multiple input reception units to which analog audio signals, on which watermark information indicating identification information is superimposed, are input, an extraction unit that is adapted to extract the identification information from each of the analog audio signals input to the multiple input reception units, and a display unit for performing display depending on the identification information extracted by the extraction unit in correspondence with the input reception unit to which the analog audio signal, from which the identification information is extracted, is input, or signal processing unit for performing signal processing depending on the identification information extracted by the extraction unit for the analog audio signal, from which the relevant identification information is extracted, and outputting the processed analog audio signal.

Audio signal processing device, audio signal processing system, and audio signal processing method

A signal processor stores at least one microprogram having m steps in total smaller in number than n steps which are to be executed within one sampling repetition period. A count corresponding to each of the n steps are generated. M steps of the at least one microprogram stored is executed a plurality of times within the one sampling repetition period to thereby execute the n steps.

Signal processor capable of executing microprograms with different step

Electronic musical instrument comprises a musical tone synthesis device, a memory and pitch control device. The musical tone synthesis device processes input signals based on at least one parameter, and synthesizes and outputs musical tones with pitches in accordance with the values of the parameters. The memory stores initial values of the parameters which generate a musical tone having a target pitch. The pitch control device detects a difference between the target pitch of the musical tone and a pitch of the musical tone outputted form the musical tone synthesis device. And, the pitch control device outputs a value of the parameter which will eliminate the difference to the musical tone synthesis device.

A musical tone synthesizing apparatus synthesizes musical tones by simulating the tone generation construction of an acoustic musical instrument. The acoustic musical instrument comprises of a tone generating element and a tone generating operator for exciting the tone generating element, thereby creating reciprocally propagating vibration within the tone generating element. The musical tone synthesizing apparatus has a parameter producing portion which automatically produces a plurality of control parameters used for controlling a simulation of the acoustic musical instrument in response to operational information representing the operation applied to the acoustic musical instrument by a performer, musical tone synthesizing portion which synthesizes a musical tone of the acoustic musical instrument, wherein the operation of the musical tone synthesizing portion is controlled in accordance with the control parameters. The parameter producing portion includes, for example, keyboard apparatus having a keyboard. By adjusting the touch of key in keyboard, it is possible to variously control the musical tone by easy operation. Accordingly, the control parameters to be need for synthesizing a musical tone are easily inputted to the musical tone generating portion. In addition, the musical tone generating portion can generate a musical tone with easy operation regardless of the ease where complicated controlling the control parameters is needed.
