  The era specifying means 31 announces the music of the music ID provided as the attribute information of the music DB 51 of FIG. 2A when the music to be played karaoke is read from the music DB 51 based on the music ID. It is a program that reads and identifies the age.

  The processing setting means 32 includes an equalizing setting unit 32A, a panpot setting unit 32B, a simulated noise addition setting unit 32C, a simulated echo setting unit 32D, and a setting table 32E. This is a program for setting the reproduction feature according to the announcement age specified by the specifying means 31. The reproduction characteristics according to the announcement age means characteristics such as frequency characteristics, left and right channel localization, noise, echo, etc. in predetermined reproduction means (for example, vacuum tube radio and jukebox) at the time of announcement. Setting is performed by an equalizing setting unit 32A, a panpot setting unit 32B, a simulated noise addition setting unit 32C, and a simulated echo setting unit 32D. Note that the reproduction feature may be set to all of the above or any one of them.

  That is, the equalizing setting unit 32A processes a frequency characteristic that is a reproduction characteristic according to the announcement date of the performance signal, and the panpot setting unit 32B is a localization (a sense of spread of the sound image) that is a reproduction characteristic according to the announcement date of the performance signal. The simulation noise addition setting unit 32C simulates and adds the noise sound of the analog record board, which is a reproduction feature according to the announcement age, to the performance signal, and the simulation echo addition setting unit 32D has a characteristic according to the announcement age. Add echo effect to audio signal only. Hereinafter, it demonstrates concretely.

  As shown in FIG. 2 (C), the reproduction characteristic of the music listening environment with frequency characteristics according to the announcement era is specifically the warm tone of monaural vacuum tube radios and jukeboxes in the 1960s. Yes, it is a reproduction feature of the echo effect of the early tape-type echo machine where analog record noise can be heard and wow and flutter are conspicuous.

  In the 1970s, it was a sound reproduction feature of a large stereo device that was widely used in ordinary homes during the high growth period, and improved frequency characteristics and a sense of localization (horizontal spread) compared to the 1960s. . In the 1980's, it is a reproduction feature of a CD sound source and a mini component sound (so-called “donshari”).

  Based on these, the setting of the reproduction characteristics of the music listening environment in equalizing is that the pass frequency of the equalizer should be 40 Hz or more and 15 kHz or less in the 1960's, and the low range of 100 Hz or less and the high range of 10 kHz or more will be lowered slightly. Reproduce the frequency characteristics of vacuum tube radios and jukeboxes at that time. In the 1970s, the equalizer passes through 20 Hz to 20 kHz, and the high frequency is reproduced flat. In the 1980s, the low frequency and high frequency are emphasized by setting the pass frequency of the equalizer to 10 Hz to 40 kHz. After the 1990s, the equalizer pass frequency is 10 Hz or more and 80 kHz or less, and the overall reproduction is flat. The setting values set by the equalizing setting unit 32A are reflected in the setting table 32E and set for the mixing amplifier 14.

  As shown in FIG. 2 (C), the setting of the reproduction characteristics of the music listening environment in the localization of the left and right channels according to the announcement age is concretely the performance signal of the left and right channels of the karaoke performance in the 1960s. It is close to monaural playback where the stereo position is set near the center to eliminate the sense of stereo spread. In the 1970s, it is about the middle of monaural and stereo. In the 1980s, it is full stereo. This is a playback feature with full stereo surround. The setting values set by the pan pot setting unit 32B are reflected in the setting table 32E and set for the mixing amplifier 14. For surround addition, a technique well known in the field of acoustics can be used, and in the present embodiment, it can be realized by a DSP provided in the mixing amplifier 14 which is a digital mixer.

  As shown in Fig. 2 (C), the reproduction characteristics of the music listening environment in the noise depending on the era of the announcement are specifically set to a sound that simulates the analog sound of "Chile Chili" noise (so-called LP noise). It is added at a predetermined volume level throughout. The predetermined volume level may be, for example, a level in which noise is conspicuous before a karaoke performance is started or in a quiet part of music, and is not so noticeable in a part where the volume of karaoke performance is high. The level is increased in the 1960s, the level is decreased in the 1970s, and so-called LP noise does not exist in the 1980s and 1990s due to the appearance of CD. The setting values set by the simulated noise setting unit 32C are reflected in the setting table 32E, and an instruction is given to a simulated noise adding unit 33 described later.

  As shown in FIG. 2 (C), the setting of the reproduction characteristics of the music listening environment in the echo effect according to the announcement age is accompanied by a wow and flutter peculiar to the early echo machine using the free running of the tape. The echo is simulated and given to the voice signal of the song. In the 1960s, the tape-type echo effect is set to a large flutter, in the 1970s, the flutter is reduced, and in the 1980s and 1990s, there is no flutter. The setting values set by the simulated echo setting unit 32D are reflected in the setting table 32E and set for the mixing amplifier 14.

  The simulated noise adding means 33 is added by reading the simulated noise data 55 stored in the storage section 30 according to the instruction of the simulated noise addition setting section 32C of the processing setting means 32, reproducing the loop and outputting it to the mixing amplifier 14. . When the sound source 26 is provided with a tone color such as LP noise and the simulated noise data 55 is MIDI data, the simulated noise addition setting unit 32C reads out the MIDI data of the LP noise and performs a music performance control unit. The process to output to 25.

  In addition, the setting of the addition of the reproduction feature in the processing setting means 32 may be performed not only on the performance signal but also on the voice signal of the singing adapted to the karaoke performance and mixed with the processed karaoke performance signal. In this case, the target of the echo effect having the characteristic according to the announcement age by the simulated echo addition setting unit 32D is added only to the audio signal.

  The background video display processing means 34 is based on the age specified by the age specifying means 31 during the karaoke performance, based on the age-specific video DB 54 of the storage unit 30 (the streets in which the atmosphere according to the age remains) Is read as a whole of the background video and is played back by the video display control means 24. The same applies to the case where the video by age is video data taken at each age (the video at that time) as the whole of the background video.

  By the way, as described above, when the video corresponding to the age is a part of the file data of the background video, the background video display processing means 34 displays the normal background video corresponding to the performance music in the video DB 52 of the storage unit 30. In addition, the video of the corresponding age is read from the video database 54 by age, a part of the video by age is inserted into the normal background video, and output to the video display control means 24 for display. In the background video display processing unit 34, normal background video read from the video DB 52 of the storage unit 30 may be processed according to the age (for example, monochrome display or sepia display).

  FIG. 3 is an explanatory diagram for selecting a retro playback setting for karaoke performance according to the release date by the remote input / output device of FIG. 1, and FIG. 4 is an explanatory diagram for each specifying process for retro playback.

When the retro reproduction is desired according to the user's preference, the retro reproduction is set by touching the display portion. When the “transfer” operation button 17E is touched by the setting of 17B, a retro reproduction flag is attached to the music ID of the selected music and transmitted to the karaoke main body 12. In the karaoke main body 12, as shown in FIG. 3B, the music ID accompanied with the retro play flag is reserved and registered in the reservation queue 41 of the RAM 23.

  The performance is started in the order of reservation registration in the reservation queue 41 shown in FIG. 3B, and when the performance of the music B whose retro reproduction flag is “ON” shown in FIG. When read from the song DB 51 based on the song ID, the age specifying means 31 reads and specifies the announcement age of the song with the song ID from the attribute information shown in FIG. Here, as shown in FIG. 4A, the music is specified as music of the 1960s.

  Based on the announcement date “1960s” of the music specified by the age specifying means 31, the processing setting means 32 refers to the setting table 32E shown in FIG. 4A and the equalizing setting unit 32A sets the set value “EQ− 4 ”is set for the mixing amplifier 14, the panpot setting unit 32B sets the setting value“ PA-4 ”for the mixing amplifier 14, and the simulated echo setting unit 32D mixes the setting value“ EC-4 ”. In addition to setting for the amplifier 14, the simulated noise addition setting unit 32 </ b> C instructs the simulated noise adding means 33 to add simulated noise at the set value “N−2”.

  On the other hand, the background video display processing means 34 reads the video of the age-specific video ID corresponding to the 1960s from the age-specific video DB 54 of the storage unit 30 as shown in FIG. By sending it out, the karaoke performance and the retro reproduction of the voice signal of the singing in accordance with the karaoke performance are performed together with the background video.

  In this way, a performance signal corresponding to the announcement date of the music is emitted and a background video is displayed, and the playback characteristics of the performance signal in the music are determined according to the announcement age of the music listening environment for the background video. The reproduction feature can be matched. In addition to performing karaoke performances as well as singing audio signals, the reproduction characteristics of the music listening environment of the announcement era can be further matched by performing retro reproduction. Further, when selecting a song for karaoke performance and making a reservation registration in the reservation queue 41, it is possible to form a music listening environment according to the user's preference by setting the processing setting to be valid or invalid for each song. It can be done.

  The karaoke apparatus of the present invention can be used in industries such as manufacture, use, and sale of karaoke apparatuses having basic karaoke functions.
