Abstract

The present invention relates to a sound source search system. The sound source search system according to the present invention comprises: sound signal input means for inputting a sound source including a rhythm; A sound source database in which the melody of the sound source is stored; And sound source searching means for detecting a melody from a sound source input from the sound signal input means and searching the database for the sound source including the melody to return the same or similar sound source.

Description

{A Audio Search System}

The present invention relates to a sound source search system, and more particularly, to a sound source search system that allows a user to listen to a song or a music song containing a melody by inputting melody instead of a search word.

In order to search for a song on the Internet, it is necessary to know the song lyrics or the name of the song, so that it is difficult to search for a song or music including the melody.

Particularly, some of the songs are well known to the public, but it is difficult to search by the runaway of the search data if the lyrics or the lyrics of the song are not known.

An object of the present invention is to provide a sound source search system capable of searching for and providing a sound source including a rhythm when a rhythm is inputted by voice or the like.

Another object of the present invention is to provide a music sound source capable of easily searching for a desired music piece by a general user by performing a search by transposing the input melody into a plurality of tones in order to overcome the difference between the inputted melody and the tune of the tune inputted into the database. To implement a search system.

According to another aspect of the present invention, there is provided a sound source search system including: a sound signal input means for inputting a sound source including a rhythm; A sound source database in which the melody of the sound source is stored; And sound source searching means for detecting a melody from a sound source input from the sound signal input means and searching the database for the sound source including the melody to return the same or similar sound source.

The database is provided with a search key, which is a search word for search for a sound source, as a search key.

The sound signal input means is a smartphone, and the sound source searching means receives a search request from the smartphone through the Internet, and returns the search result to the smartphone via the Internet.

And the sound source searching means includes transposition means for transposing and inputting the inputted search use rhythm.

According to the present invention as described above, it is possible to easily search for songs and music that are only part of the melody.

1 is a system configuration diagram of a sound source search system according to an embodiment of the present invention.
FIG. 2 is a flowchart illustrating a sound source searching process by the sound source searching system of the embodiment of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a sound source search system according to the present invention will be described in detail with reference to the accompanying drawings.

The sound source search system of the embodiment of the present invention includes: a sound signal input means for inputting a sound source including a rhythm; a sound source database storing various music sound sources and bibliographic information about the sound source; And sound source searching means for detecting a melody and searching for a musical sound source including the melody in the database and returning the same or similar sound source.

The sound signal input means of the present embodiment may include a sound input device such as a microphone of a microphone smartphone connected to a PC, and a sound signal may be input to a voice, a musical instrument sound, or the like.

In the present embodiment, the sound source searching means comprises a sound detecting means for detecting a sound from a sound source to be input, a transposing means for transposing the sound detected by the sound detecting means to a predetermined tone, and a rhythm detected by the rhythm detecting means, A music comparison means for comparing the melody of the music piece with the melody of the music piece in the database, and a music piece providing means for returning and providing a similar music piece when the similar music piece is detected.

The sound source searching means of the present embodiment can operate on a web by a search server and a client structure. The client can be mounted on a PC or a smart phone. The search server searches the corresponding sound source from the database It is possible to provide it as a client.

In the present embodiment, the melody detection means may be applied to an application program installed in a PC or a smart phone. When the melody detection unit is provided in a search server and the sound source itself is transmitted to a search server on the Internet through a PC or a smart phone, And it is possible to change according to the embodiment.

Since the tone shifting means of the present embodiment is often different in tone from the tone inputted into the database, the tone shifting means of the present embodiment can easily detect a desired tone by transposing or modulating even when the tone of the input tone source is different .

On the other hand, it is also possible to provide a modulation means for converting the tone of the melody with a sound signal of a certain frequency in addition to the transposition.

In addition, it is possible for the music comparison means to detect a music source including a musical composition including the same musical composition and a musical composition including a musical composition having a predetermined percentage or more, by comparing the musical composition requested to be searched with the database and displaying the similarity It is possible to provide it.

The music providing means of the present embodiment can provide the client with bibliographic information for the same or similar music piece, for example, a song name, a composer, a melody for search, and lyrics (only if available) in a list form.

In addition, it is possible to provide the entirety of the music piece to the client for a fee or free of charge according to the service policy at the request of the client.

The PC or the smartphone of the embodiment of the present invention can display the data provided by the music providing means on the display means and can play and listen to the melody for searching in the user's displayed list, It is possible to request and listen to the entire musical piece to enjoy it.

The database of the embodiment of the present invention stores bibliographic information of various pieces of music such as a song name, a composer, a melody for search, lyrics, and the like, and the melody for search includes one or two well-known melodies And a melody for searching may be provided for a predetermined time or a predetermined section as needed.

The retrieval loudspeakers stored in the database are transposed to a predetermined tone and stored for convenience of retrieval.

In addition, the database can convert the elements of the search-use loudspeaker into digital data according to a predetermined rule and store the elements such as the duration time beats of the loudness and the change of the pitch of the loudness. Change, and duration of each note are compared to find similar melodies for search.

In addition, the database can detect the entire piece of music corresponding to the searching sound source according to the request of the sound source searching means and provide the sound source searching means.

In the embodiment of the present invention, the sound source search system may be provided with a means for further inputting data for a composer or a part of the lyrics in addition to the melody, thereby enabling to search and provide a melody corresponding to the melody more quickly and accurately Do.
