In addition, according to the delivery system of this embodiment, also can carry out a plurality of chanteurs being sung the synthetic multiple record of sound (perhaps identical chanteur sing sound) in the later stage.In existing systems; Owing to be with singing sound and musical sound 1 voice data and the mode of in server, storing after as mixing; So append under other situation of singing sound in the later stage, at first voice data is decoded and be transformed to voice signal, carry out encoding after the mixing at the voice signal of singing sound with other; Therefore, produce the tonequality deterioration.But, in this embodiment, preserve as different data with musical sound, so sing to what when playing, hope multipleization that file is decoded and synthetic getting final product owing to singing sound.Therefore, do not produce the tonequality deterioration that causes by multiple record.
Below, use process flow diagram, the action of the delivery system of this embodiment is described.The process flow diagram of the action when Fig. 7 is the expression register.The process flow diagram of the action when Fig. 8 is expression mixing data delivery.
At first, as shown in Figure 7, utilize the operating portion 15 of Caraok device 7 to sing the appointment of the register and the melody of sound if hope the chanteur of public singing sound, then CPU11 accepts register (s11).At this moment, CPU 11 also accepts from operating portion 15 input chanteurs' brief introduction and message etc.
If CPU 11 has accepted register, then specified music data is read and the performance (s12) of playing Karaoka, and, generated and sing file (s13) based on from the singing voice signal of microphone 16 via the chanteur of A/D transducer 17 inputs.In addition, based on the melody numbering of the melody of being played, speed, volume etc., generate synchronizing information (s14).CPU 11 after the performance of melody finishes, with generated sing file and synchronizing information is uploaded (s15) to central part 1.Central part 1 with uploaded sing file and synchronizing information is recorded in (s16) among the HDD 33.Like this, chanteur's the file of singing is logined in central part 1.The CPU 31 of central part 1 uses each chanteur's information of singing file of being uploaded, html file is upgraded, and the WEB page that user PC 4 is visited upgrades (s17).
Then, as shown in Figure 8, the user (user of user PC 4) of request mixing data delivery is for the guide look with reference to the chanteur, and sings the demonstration request (s21) of file.Should show request to central part 1 transmission, central part 1 is accepted WEB and is shown request (s22).The CPU 31 of central part 1 carries out the WEB display process (s23) of html file to user PC 4 transmission.On the display 49 of user PC 4, show based on the WEB page (s24) of 1 html file that sends from central division.Like this, on display 49, show the guide look of singing file shown in Figure 5.
The user is through with reference to the guide look of singing file that is shown on the display 49, thereby selects to hope the chanteur that listens to, and carries out the delivery request (s25) of mixing data.CPU 41 extracts the user-selected filename of singing file from html file, and to central part 1 notice.Thus, accept delivery request (s26).
Then; The processing (s27, s28) of in central part 1 (perhaps charging server etc.) and user PC 4, charging; If the charge processing finishes; Then the CPU 11 of central part 1 sings file and synchronizing information is read with pairing from HDD 33, sings the decoding of file, generates based on what sing file and sings the sound voice signal.In addition, it not is necessary that charge is handled, and can omit the processing of s27 and s28 yet.Then, the music data of the melody numbering of being put down in writing in the synchronizing information is read from HDD 33,, music data is carried out sequencing handle, and sound source 38 is controlled according to speed of being put down in writing in the synchronizing information and volume.Thus, identical speed, volume reproduced Karaoke and played with the recording of singing sound the time, and the sound of singing through the output chanteur carries out synchronous playing (s29) simultaneously.But, play the identical file of singing in the past, and be stored under the situation among the HDD 33 as the mixing data, if read the mixing data, then do not need to carry out again synchronous playing from HDD 33.In addition, also can utilize the free time of the processing of central part 1, generate each mixing data in advance.In the case, even exist at the same time under the situation of a plurality of delivery request, also can carry out sending of mixing data immediately.Certainly, in the case, also be kept among the HDD 33, so can change the mixing balance in the later stage owing to singing file.
Then, the singing voice signal of synchronous playing and the note signal of Karaoke melody are carried out mixing, generate mixing data (s30), make user PC 4 download (s31).At this moment, the download time of singing file that is downloaded of 31 couples of the CPU of central part 1 is carried out count increments (s32).
The CPU 41 of user PC 41 downloads mixing data (s33) from central division, and in HDD 43 (perhaps RAM 42), preserves.Then, CPU 41 carries out the decoding of mixing data, sings the broadcast (s34) of sound and musical sound.
The generation of mixing data and send to concentrate accordingly with 1 first melody and carry out also can be downloaded as flow data successively.In addition, also can be free under the situation of sending with low bitrate, under the situation of sending, charge with high bit rate (bit rate during recording).
In addition; Shown in Fig. 3 (C) and Fig. 3 (D); The broadcast of in synchronizing information, respectively singing file as expression regularly information and record expression from the information of playing the beginning elapsed time, or sing under the situation of the mistiming (, being the time that begins to count from performance) between the file, in the CPU 31 of central part 1 for the file of singing at first; The sequencing that is accompanied by music data is handled, and output is based on the voice signal of respectively singing file.Under the situation that synchronizing information constitutes as MIDI data (the expansion rail of music data), through reading the MIDI data of this synchronizing information by sequencer, thereby can export based on the voice signal of respectively singing file.
Here, the user operating portion 45 is operated, carried out under the situation of change indication of mixing balance (s35), CPU 41 is to central part 1 request of changing (s36).In the change request, include the information that the mixing balance of singing sound and musical sound is indicated.If the CPU 31 of central part 1 has accepted change request (s37), then according to the information of the expression mixing balance that is comprised in this change request, the mixing balance of change frequency mixer 39 regenerates mixing data (s38).Then, the mixing data after CPU 31 will generate are once more sent (s39) to having carried out change requesting users PC 4.In user PC 4, the mixing data of sending are once more play (s40), till playing end, carry out above processing (s41) repeatedly.
In addition, for the mixing data of sending once more, can be from the sending once more of the melody of having made the change request midway, also can from melody begin at first send once more with mixing balance after changing.
As noted above, in this embodiment, form by different sources with musical sound owing to sing sound, so can control volume independently, can easily change the mixing balance.
In addition, the user also can carry out the change indication of effect, the indication of speed change in the change indication of above-mentioned mixing balance.Under the situation of the indication of carrying out the speed change, the CPU 31 of central part 1 handles with the sequencing that speed is after changing carried out music data, and also sings the change of the broadcasting speed of file.In the case, CPU 31 (perhaps not shown DSP) carries out following processing, that is, when keeping singing the interval of sound, on time shaft, make voice signal flexible.Keeping singing the processing that in the interval of sound voice signal is stretched, for example carry out in the following manner.
That is, CPU 31 will generate the new time shaft waveform (middle waveform) that a plurality of time shaft waveforms are synthesized into based on the voice signal cutting of singing sound of singing file for being the time shaft waveform of unit with the sampling period.Middle waveform is also synthetic through the time shaft waveform of front and back smoothly being changed (cross-fade), thereby generate.And, if waveform in the middle of between original time shaft waveform, inserting then can stretch on time shaft when keeping singing the interval of sound.Under the situation that voice data is compressed, waveform is replaced the processing of original time shaft waveform in the middle of utilizing.For example,, then can be stretched as 2 times (broadcasting speed is 1/2),, then can compress (making broadcasting speed become 2 times) if carry out replacement Treatment if whenever insert processing at a distance from 1 sampling.If whenever insert processing at a distance from 2 samplings, then can be stretched as 1.5 times, if whenever insert processing, then can be stretched as 1.33 times at a distance from 3 samplings.
In addition, CPU 31 indicates under the situation of tone change the user, carries out the tone change (replacing of note numbering (note number)) of music data, and carries out pitch (pitch) change of singing voice signal.The pitch change can realize through the resampling that carries out voice signal.In addition, also can carry out the frequency characteristic change of voice signal.
In addition, in this embodiment, show the chanteur and use Caraok device 7 to sing the example of the operation of file login, but also can constitute, the function of additional microphone and recording in central part 1 uses central part 1 login to sing file.More simply, also can use the user PC 4 of the function that has realized Caraok device 7 and realize.In the case, the software of user PC 4 is realized textural elements such as sequencer and sound source, constitutes Karaoke and plays the terminal.
