A computer program makes a computer perform: a measuring process of measuring a beat candidate value, which is the number of beats of content per unit time; a reference setting process of setting a beat reference value according to a user's input; and a determining process of determining a beat definite value set in the vicinity of the beat reference value, from among the measured beat candidate value.

Computer program, information reproduction device, and method

An information reproduction apparatus which can perform repetitive reproduction is provided. In the apparatus, information recorded in an information storage medium is read. The read information is decoded. The decoded information is stored in a predetermined region of a storage device. During reproduction, information is sequentially read out and outputted in order of precedence at the time of writing the decoded information while the decoded information is stored in the predetermined region. When a start position of repetitive reproduction is designated, a repetition reproduction range is set. The repetition reproduction range is a range that would include the decoded information to be reproduced at one repetition reproduction. The decoded information is maintained in the repetition reproduction range. When an instruction to start the repetitive reproduction is provided, the decoded information in the repetition reproduction range is outputted and the decoded information subsequent to the repetition reproduction range is acquired.

Information reproduction apparatus and information reproduction method

Both of one audio information and another audio information are recorded on a same information record medium. An audio information reproducing apparatus is provided with: a detecting device for detecting said one audio information and said another audio information from the information record medium and also detecting a time period required for one beat of the detected another audio information; and an accumulating device for accumulating said one audio information detected from the information record medium to thereby continue reproducing and outputting said one audio information through the accumulating device. The audio information reproducing apparatus is also provided with a controlling device for controlling the detecting device to detect said another audio information and the time period required for one beat, within a time duration that the accumulated one audio information is being reproduced and outputted through the accumulating device.

Method of and apparatus for reproducing audio information, program storage device and computer data signal embodied in carrier wave

An information reproduction apparatus which can perform repetitive reproduction is provided. In the apparatus, Information read from an information recording medium is decoded by the plurality of decoding devices. Then a source of an output of the information reproduction apparatus is switched among outputs of a plurality of the decoding devices. If a start position to start repetitive reproduction is designated, another decoding device except one decoding device whose output is currently switched as the source is controlled so as to be able to begin to decode the information on and after the start position. Then if a start instruction is provided, the source is switched from the output of the one decoding device to the output of the another device. Further, the another decoding device is controlled to decode the information on and after the start position, and the one decoding device is controlled to be able to begin to decode the information on and after the start position.

An apparatus for sampling partial audio information from audio information and storing it in a memory device provided with: a sampling device for sampling the partial audio information from the audio information in the sampling time which is a integral multiple of a time interval between each beat and the next in the audio information, and a storing device for storing the sampled partial audio information in a memory device.

Apparatus and method for sampling and storing audio information and apparatus for outputting audio information

Apparatus and method for sampling and storing music, and apparatus for outputting music

An audio information reproducing apparatus reproduces one audio information and reproduces another audio information after said one audio information. The apparatus is provided with: a detecting device for detecting one time period required for one beat of said one audio information, and also detecting another time period for one beat of said another audio information; and a reproducing device for reproducing said another audio information continuously to said one audio information while controlling the detected another time period to be coincident with the detected one time period. Alternatively or additionally, the apparatus is provided with: a detecting device for detecting one beat timing which is a timing of a beat of said one audio information and also detecting another beat timing which is a timing of a beat of said another audio information, so that the reproducing device controls the detected another beat timing to be coincident with the detected one beat timing.

A method of and an apparatus for processing communication data transmitted from a data center such as a sing-along data center to a terminal communication apparatus such as a communication type sing-along apparatus via a communication line. The method and apparatus are such that a data file may be stored in a first memory provided in the terminal communication apparatus when said data file has been transmitted from the data center while the terminal communication apparatus itself is not in operation, a version of the data file stored in the first memory is compared with a version of an existing data file formerly recorded in a second memory provided in the terminal communication apparatus when said terminal communication apparatus is in operation and said second memory is in ON state, the data file formerly recorded in the second memory is replaced by the data file recorded in the first memory if it is determined that the version of the data file recorded in the second memory is older than the version of the data file recorded in the first memory.

Method of and apparatus for processing data transmitted through a communication line

A magnetic recording and reproducing device in which an optimum recording bias current, optimum recording level and optimum recording equalization characteristic are automatically set wherein a desired MOL balance dependent upon a difference of a magnetic characteristic is achieved. A recording bias is varied at predetermined time intervals. A variable low-frequency oscillator supplies a low-frequency signal upon which the recording bias current is superposed for recording upon a magnetic medium. The maximum value of a reproduced signal of the recorded signal is detected and the recording bias current set to supply an optimum recording bias current corresponding to the maximum value of the reproduced signal. The low-frequency oscillator is set to oscillate at an optimum frequency dependent upon at least one of the type of the magnetic medium and a magnetic characteristic thereof.

Magnetic recording and reproducing device

A process for calculating the amount of recording tape or time left remaining on a tape reel includes sensing the rotational period of both the supply and take-up reels, and performing operations on this data to derive the value for the remaining/transported tape amount, the operations performed depending upon the direction of tape travel. In addition, the process may include disregarding data obtained during times of highly variable tape speed, such as when changing tape transport direction, etc. The invention may be used in connection with a reversible-type tape recorder capable of reproduction or recording in both tape transport directions.

Process for detecting transported and residual tape amounts

A tape recorder for use in situations where repetitive reproduction is required, such as in language teaching, is provided with an automatic repeat function. The inputs to the device include the length of tape to be repeated, the number of repetitions, and the overlap tape length between adjacent repeated tape portions, provided to allow more continuity. The functions, e.g. playback and rewinding, of the tape recorder are controlled according to the output of a tape counter and the above input parameters. The use of the invention allows for repeated reproduction without the formation of silent, e.g. blank portions on the tape between adjacent recorded portions.
