In addition, the delivery system according to the present embodiment, sings file owing to only uploading in central part 1, so can will sing sound and musical sound stores respectively in server, and does not make uplink time increase.Because the data (music data) of the data (singing file) Yu musical sound of singing sound are separately stored in the HDD 33 of central part 1, so can also easily realize changing mixing balance or modification effects individually in the later stage.
In addition, delivery system according to the present embodiment, also can carry out in the later stage multiple chanteur being sung the multiple record that sound (or identical chanteur sing sound) synthesizes.In existing system, owing to being the mode that will sing sound and musical sound and store in server as the voice data of 1 after mixing, so when the later stage add other sing sound, first voice data decoded and be transformed to voice signal, encode after other the voice signal singing sound is carried out mixing, therefore, tonequality deterioration is produced.But, in the present embodiment, due to will sound be sung and musical sound is preserved as different data, so wish that the file of singing of multiplex is decoded and synthesizes to when playing.Therefore, the tonequality deterioration caused by multiple record is not produced.
Below, use process flow diagram, the action of the delivery system of present embodiment is described.Fig. 7 is the process flow diagram of action when representing register.Fig. 8 is the process flow diagram of action when representing mixing data delivery.
First, as shown in Figure 7, if wish that the chanteur of public singing sound utilizes the operating portion 15 of Caraok device 7 to carry out singing the register of sound and the appointment of melody, then CPU11 accepts register (s11).Now, CPU 11 also accepts the brief introduction and message etc. that input chanteur from operating portion 15.
If CPU 11 receives register, then specified music data read and carry out Karaoke and play (s12), and based on the singing voice signal of the chanteur inputted via A/D transducer 17 from microphone 16, file (s13) is sung in generation.In addition, based on the melody numbering, speed, volume etc. of played melody, generate synchronizing information (s14).CPU 11, after the performance of melody terminates, sings file and synchronizing information is uploaded (s15) to central part 1 by generated.Central part 1 sings file and synchronizing information is recorded in (s16) in HDD 33 by uploaded.Like this, the file of singing of chanteur is logged in central part 1.The CPU 31 of central part 1 uses each chanteur's information singing file uploaded, and upgrades, and upgrade (s17) the WEB page that user PC 4 accesses html file.
Then, as shown in Figure 8, the guide look of the user (user of user PC 4) of request mixing data delivery chanteur in order to reference, and carry out the display request (s21) singing file.This display request sent to central part 1, central part 1 accepts WEB display request (s22).The CPU 31 of central part 1 carries out the WEB Graphics Processing (s23) transmitted to user PC 4 by html file.On the display 49 of user PC 4, show the WEB page (s24) based on the html file sent from central part 1.Like this, display 49 shows the guide look singing file shown in Fig. 5.
User by referring to the guide look singing file shown on display 49, thus selects the chanteur that hope is listened to, and carries out the delivery request (s25) of mixing data.CPU 41 extracts the user-selected filename singing file from html file, and notifies to central part 1.Thus, delivery request (s26) is accepted.
Then, at central part 1(or charging server etc.) and user PC 4 in carry out charge process (s27, s28), if charge process terminates, then corresponding is sung file and synchronizing information reading by the CPU 11 of central part 1 from HDD 33, carry out the decoding singing file, generate and sing speech tone signal based on what sing file.In addition, charge process is not necessary, can omit the process of s27 and s28 yet.Then, the music data of melody described in synchronizing information numbering is read from HDD 33, according to speed described in synchronizing information and volume, sequencing process is carried out to music data, and sound source 38 is controlled.Thus, reproducing to play Karaoka play with the speed identical with when singing the recording of sound, volume, synchronously playing (s29) by exporting the singing sound of chanteur simultaneously.But, play in the past and identically sung file, and when being stored in HDD 33 as mixing data, if read mixing data from HDD 33, then do not needed to re-start synchronous broadcasting.In addition, also can utilize the free time of the process of central part 1, generate each mixing data in advance.In the case, even if when there is multiple delivery request at the same time, also sending of mixing data can be carried out immediately.Certainly, in the case, be also kept in HDD 33 owing to singing file, so mixing balance can be changed in the later stage.
Then, mixing is carried out to the synchronous singing voice signal play and the note signal of playing Karaoka melody, generates mixing data (s30), user PC 4 is downloaded (s31).Now, the CPU 31 of central part 1 carries out count increments (s32) to the download time singing file be downloaded.
The CPU 41 of user PC 4 downloads mixing data (s33) from central part 1, and to HDD 43(or RAM 42) middle preservation.Then, CPU 41 carries out the decoding of mixing data, carries out the broadcasting (s34) singing sound and musical sound.
The generation of mixing data and send to concentrate accordingly with 1 first melody and carry out, also can download as flow data successively.In addition, also can be free when sending with low bitrate, charge when sending with high bit rate (bit rate during recording).
In addition, as shown in Fig. 3 (C) and Fig. 3 (D), in synchronizing information as represent the broadcasting timing respectively singing file information and record represent elapsed time from playing information or mistiming of singing between file (for file of singing at first, the time counted from playing) when, in the CPU 31 of central part 1, along with the sequencing process of music data, and export based on the voice signal respectively singing file.When synchronizing information is formed as MIDI data (the expansion rail of music data), by being read the MIDI data of this synchronizing information by sequencer, thus the voice signal based on respectively singing file can be exported.
Here, user, operating portion 45 is operated, carry out mixing balance change instruction when (s35), CPU 41 to central part 1 carry out changes asks (s36).In change request, the mixing included singing sound and musical sound balances the information indicated.If the CPU 31 of central part 1 receives the request of changing (s37), then according to the information of the expression mixing balance comprised in this change request, change the mixing balance of frequency mixer 39, regenerate mixing data (s38).Then, the mixing data after again generating to be sent (s39) to the user PC 4 having carried out the request of changing by CPU 31.In user PC 4, the mixing data of again sending are play (s40), till broadcasting terminates, repeatedly carry out above process (s41).
In addition, for the mixing data of again sending, again can send from the midway of the melody of having made the request of change, also can from melody at first again send with the mixing balance after changing.
As noted above, in the present embodiment, owing to singing sound and musical sound is formed by different sources, so volume can be controlled independently, mixing balance easily can be changed.
In addition, in the change instruction that user also can balance in above-mentioned mixing, the instruction of the change instruction of effect, speed change is carried out.When carrying out the instruction of speed change, the CPU 31 of central part 1 carries out the sequencing process of music data with the speed after change, and also carries out the change of the broadcasting speed singing file.In the case, CPU 31(or not shown DSP) carry out following process, that is, while the interval of sound is sung in maintenance, make voice signal stretch on a timeline.The process making voice signal flexible on a timeline while keeping singing the interval of sound, such as, carry out in the following manner.
That is, CPU 31 will be the time shaft waveform in units of the sampling period based on the voice signal cutting singing sound singing file, generate the new time shaft waveform (middle waveform) obtained by multiple time shaft Waveform composition.Middle waveform is by synthesizing the smoothing conversion of time shaft waveform (cross-fade) of front and back, thus generate.Further, if insert middle waveform between original time shaft waveform, then while the interval of sound is sung in maintenance, can stretch on a timeline.When compressing voice data, carry out utilizing middle waveform to replace the process of original time shaft waveform.Such as, if carry out insertion process every 1 sampling, then can be stretched as 2 times (broadcasting speed is 1/2), if carry out replacement Treatment, then can carry out compressing (making broadcasting speed become 2 times).If carry out insertion process every 2 samplings, then 1.5 times can be stretched as, if carry out insertion process every 3 samplings, then 1.33 times can be stretched as.
In addition, CPU 31 is when user indicates tone to change, and the tone carrying out music data changes (replacing of note numbers (note number)), and the pitch (pitch) carrying out singing voice signal changes.Pitch changes and can realize by carrying out the resampling of voice signal.In addition, the frequency characteristic also can carrying out voice signal changes.
In addition, in the present embodiment, show chanteur and use Caraok device 7 to carry out singing the example of the operation that file logs in, but also can be configured to, the function of additional microphone and recording in central part 1, use central part 1 to log in and sing file.More simply, also can use the user PC 4 of the function achieving Caraok device 7 and realize.In the case, the textural elements such as the software simulating sequencer of user PC 4 and sound source, form Karaoke and play terminal.
In addition, for singing listening to of file, showing the example using common home-use personal computer, but Caraok device 7 can certainly be used to listen to.
In the present embodiment, as shown in Fig. 3 (B), describe the example that synchronizing information is made up of head, velocity information, information volume (Vol.), timing information (velocity variable).But, in synchronizing information, except above-mentioned information, also can comprise that microphone echoes, reverberation, compression, the change of voice etc. efficacy parameter.In the case, when singing the register of sound, log in the synchronizing information comprising efficacy parameter.Specifically, such as, in the process timing that the synchronizing information of the s14 of Fig. 7 generates, the efficacy parameter now set by Caraok device 7 is reflected in synchronizing information.Play Karaoka play time, use this efficacy parameter, microphone to be echoed etc. and reflect in voice signal.Thus, the effect set when singing sound recording can be reflected in Karaoke performance, the user sent accepting mixing data can enjoy the performance having more presence.
In the present embodiment, carry out charge process when mixing data delivery, but also can carry out charge process when chanteur uploads and sings file.That is, sing file and synchronizing information when uploading during register in the s11 of Fig. 7 and in s15, charge to chanteur.Thus, the system of following purposes can be realized, that is, such as hold chanteur can pay the Karaoke match participated in time, upload self sing file time from each chanteur's collection cost as initial charge.
