  • Patent number: 9398623
    Abstract: A wireless access point superimposes establishment information used for establishing a wireless communication channel between a communication terminal and the own device on a sound signal, and emits a sound wave corresponding to the sound signal to a speaker. The communication terminal acquires the sound signal representing the sound wave detected by a microphone, and extracts the establishment information from the acquired sound signal. The communication terminal transmits the extracted establishment information to the wireless access point to establish the wireless communication channel between the communication terminal and the wireless access point, and conducts a communication through the established wireless communication channel.

  • Patent number: 7087829
    Abstract: A music work filed for application through on-line transmission or the like is subjected to viewing/listening by audiences through plural kinds of media. The audiences make access to an internet homepage on an internet server 4 of the holder of the audition through a PC (personal computer) 1 or 2, and performs trial-listening of the music work. The audiences also view and/or listen to a live performance in a performance hall. Alternatively, the audiences may view and/or listen to a video performance of television broadcast. Evaluation data based on the results of viewing/listening is input on the internet homepage by the audiences through a PC 6 or a portable communication terminal device 7 on evaluation items conforming to the characteristics of the media. A music work is selected based on the above evaluation.

  • Patent number: 6801898
    Abstract: According to a time-scale modification method or apparatus, wave segments each having a prescribed cutting length are sequentially cut from original digital signal waves stored in a waveform memory and are then spliced together by way of cross-fading, so it is possible to realize time-scale modification (i.e., compression or expansion with respect to time) in accordance with a designated time-scale modification factor. Herein, time-scale modification parameters such as a cross-fade duration, a search start time and a search end time are produced in response to the designated time-scale modification factor. In addition, a cutting start position is used for cutting a next wave segment following a present wave segment. The cutting start time is determined within a period of time between the search start time and search end time in such a way that it is placed to provide a best similarity between the wave segments having prescribed portions which are connected with each other by way of cross-fading.

  • Patent number: 6583348
    Abstract: A server apparatus is provided for conducting an evaluation of a music piece with an external terminal apparatus. In the apparatus, a communication unit is used to exchange information with the external terminal apparatus. A first transmitting section transmits first prompt information to the external terminal apparatus through the communication unit, the first prompt information being effective to prompt a first evaluation of a music piece. A second transmitting section transmits inquiry information to the external terminal apparatus through the communication unit, the inquiry information inquiring whether or not to proceed with a second evaluation of the music piece. A receiving section receives request information from the external terminal apparatus in response to the inquiry information through the communication unit, the request information requesting the second evaluation.

  • Patent number: 6487536
    Abstract: A time-axis compression/expansion system compresses or expands a multichannel signal at a specified compression/expansion rate. Waveform segments are sequentially cut out from each channel signal. A cutting starting point of a leading end portion of a waveform segment following each preceding waveform segment of the cut out waveform segments is determined commonly between the channel signals, based on two portions of a waveform of a synthesized signal formed by synthesizing the channel signals within a range of predetermined search parameters of the waveform of the synthesized signal. The two portions correspond to a time period over which cross-fading is to be carried out and are most similar to each other. The preceding waveform segment and the following waveform segment cut from each channel signal are spliced together by cross-fading a trailing end portion of the preceding waveform segment and the leading end portion of the following waveform segment.

  • Patent number: 5974387
    Abstract: Sampled sound data is compressed with a vector quantizing technique and then transmitted via a communication line. Received sound data is decoded, compressed with an ADPCM technique, and then stored into a memory. In response to a request for reproduction, the ADPCM sound data is read out, decoded, and then sounded. As another example, in a karaoke device, sample sound data is supplied after being compressed with the vector quantizing technique, in addition to MIDI-form music performance data. A music sound is reproduced on the basis of the MIDI-form music performance data, and at the same time a sound is reproduced by decoding the vector-quantized sound data. As another example, in a karaoke device, data obtained by compressing sampled sound data with the vector quantizing technique is mixed with data obtained by compressing sampled data with the ADPCM technique, and in reproduction, a predetermined decoding process is executed after identifying with which of technique is compressed data to be reproduced.
