Karaoke antiphonal singing method and system based on the internet
Technical field
The present invention relates to Internet technology, particularly a kind of Karaoke antiphonal singing method and system based on the internet
Background technology
In the music application of internet; Online K song (is exactly in Qu Ku, to choose song; System plays captions and accompaniment; The user is with singing, system synchronization is synthetic and play back through the sound card audio amplifier) be an application direction that receives praises from customers, and to have emerged in large numbers many be the research and development of products merchant and the operator of core with online K song.But at present, the product form of online K song still rests on the technical approach of single performance, and the song of carrying out on the internet of users' expectation does not have proven technique scheme and product to realize to the chorus of joining in the chorus.Trace it to its cause, mainly contain two big technical bottlenecks:
Voice latency.The Karaoke antiphonal singing has strict more network delay requirement with respect to real-time phonetic.Real-time phonetic can allow between the both call sides to exist bigger delay (<1000ms) with packet loss (<5%), only need both sides can understand mutually within a certain period of time to look like separately and get final product.But the Karaoke antiphonal singing is owing to stress instantaneity more, and its network delay can not surpass half and clap (96BPM is about 300ms down), and considers the integrality of song, and packet loss can not surpass 1%.With regard to present internet and Virtual network operator present situation, generally to reach this technical indicator and be difficult to.
Accompaniment and lyrics resource.The antiphonal singing both sides need to hear synchronous accompaniment when singing, see lyrics synchronized, and be on the synchronous time shaft.That is to say needs that identical accompaniment and lyrics content are arranged on both sides' computer, and this is also relatively more difficult in practical application.
Summary of the invention
The technical matters that the present invention will solve provides a kind of Karaoke antiphonal singing system and method based on the internet, can delay under the bigger complex environment, for the user provides desirable antiphonal singing effect.
For solving the problems of the technologies described above, the Karaoke antiphonal singing method based on the internet of the present invention may further comprise the steps:
The first step, one be connected in the internet the song in Qu Ku, chosen according to the vocal accompaniment user of vocal accompaniment user terminal, the accompaniment of playing this song;
Second goes on foot, and the vocal accompaniment user terminal carries out reverberation and audio mixing processing with the accompaniment of this song with the part that the vocal accompaniment user sings, and the accompaniment that forms this song adds the track of vocal accompaniment;
The 3rd step, the track that the vocal accompaniment user terminal adds vocal accompaniment with the accompaniment of this song encode the back through the transfer server that is connected in the internet be forwarded to one be connected in the internet the chorus user terminal;
The 4th step, said chorus user terminal, when chorus after the user chooses the accompaniment of this song to add the track of vocal accompaniment, the track that the accompaniment of this song is added vocal accompaniment is decoded and is play;
In the 5th step, the track that said chorus user terminal adds the accompaniment of this song vocal accompaniment carries out reverberation and audio mixing processing with the part that said chorus user sings, and the accompaniment that forms this song adds to accompany and adds the track of chorus;
In the 6th step, said chorus user terminal adds track that vocal accompaniment the adds chorus back of encoding with the accompaniment of this song and is dealt into the online client terminal of listening to of all internets through a mass-sending server zone that is connected in the internet;
In the 7th step, the online client terminal of listening to of said internet when listening to after the user chooses the accompaniment of this song to add vocal accompaniment to add the track of chorus, adds track that vocal accompaniment adds chorus with the accompaniment of this song and decodes and play.
In the 6th step, the mass-sending server does not add the track that vocal accompaniment adds chorus with said chorus user terminal with the accompaniment of this song and sends to said vocal accompaniment user terminal, chorus user terminal.
For solving the problems of the technologies described above, the Karaoke antiphonal singing system based on the internet of the present invention comprises through internet continuous vocal accompaniment user terminal, transfer server, chorus user terminal, mass-sends server, listens to client terminal;
Said vocal accompaniment user terminal; The accompaniment of the song that the user that is used for accompanying selects is play; And the accompaniment of this song and the part that the vocal accompaniment user sings carried out reverberation and audio mixing processing; The accompaniment that forms this song adds the track of vocal accompaniment, and the track that the accompaniment of this song adds vocal accompaniment is sent to said transfer server through the internet;
Said transfer server is used for the track that accompaniment with the said song that receives adds vocal accompaniment and is forwarded to said chorus user terminal;
Said chorus user terminal; The track that the accompaniment of the song that the user that is used for chorusing selects adds vocal accompaniment is decoded and is play; And the accompaniment of this song added the track of vocal accompaniment and part that said chorus user sings carries out reverberation and audio mixing processing; The accompaniment that forms this song adds the track that vocal accompaniment adds chorus, and the accompaniment of this song is added track that vocal accompaniment the adds chorus back of encoding is sent to said mass-sending server through the internet;
Said mass-sending server is used for accompaniment with the said song that receives and adds track that vocal accompaniment adds chorus and be dealt into all online client terminals of listening to through internet group;
The said client terminal of listening to is used for that the accompaniment of listening to the song that the user selects is added track that vocal accompaniment adds chorus and decodes and play.
Said mass-sending server adds the track that vocal accompaniment adds chorus with the accompaniment of the said song that receives and does not send to said vocal accompaniment user terminal, chorus user terminal.
Karaoke antiphonal singing method and system based on the internet of the present invention to the complex situations of present internet present situation and practical application, are decomposed into the vocal accompaniment and two steps of chorusing with traditional song antiphonal singing; And the processing mode through " vocal accompaniment earlier, back chorus, virtual time axle "; Adopt asynchronous that the one-way data transmission manner avoids that network delay causes; Audio mixing and axle control unified time through two different times reach final chorus effect, and vocal accompaniment person is under this application model; Can not hear chorus person's sound; And chorus person can hear vocal accompaniment person's sound, and vocal accompaniment person is responsible for accompaniment is provided, and chorus person need not to have accompaniment in this locality.The technical bottleneck that the present invention has avoided voice latency and accompaniment lyrics resource to cause; There is not rigid requirement for antiphonal singing both sides voice latency and accompaniment resource; Can postpone under the bigger complex environment; Realize comparatively desirable antiphonal singing for the user provides desirable antiphonal singing effect, broken through present network K song and can't realize that two people carry out the antiphonal singing perhaps restriction and the bottleneck of chorus in the strange land, can produce to have interactive and recreational product more and use form.
