Embodiment Construction

[0016] Refer to figure 1 , Is the structural block diagram of the audio sequencer of the present invention.

[0017] An audio sequencer, including: a music event data buffer 1, an event interpreter 2;

[0018] A piece of music is converted into music event data with a specific code through a specific software. This music event data is sequentially put into the music event data buffer 1, and the event interpreter 2 reads the music event data from the music event data buffer 1. , And interpret these data, generate interpretation data,

[0019] The audio sequencer of the present invention also includes an instant data buffer 3, a command interpreter 4, and a control device 5;

[0020] After the instant data buffer 3 receives the instant command data transmitted from the outside, the command interpreter 4 fetches the instant command data from the instant data buffer 3 and interprets these instant command data; the event interpreter 2 or the command interpreter The interpretation data...

Abstract

The invention relates to the field of audio synthesis, and specifically discloses an audio sequencer. The audio sequencer of the present invention includes: a music event data buffer, an event interpreter, an instant data buffer, a command interpreter, and a control device. The control device issues a control command so that the processing priority of the immediate data buffer is higher than that of the music event data buffer. According to the present invention, the user can instantly change the music being played.

Description

Technical field [0001] The invention relates to the field of audio synthesis, in particular to an audio sequencer. Background technique [0002] With the rapid development of the multimedia field, people's requirements for multimedia are getting higher and higher. For example, in terms of ringtones related to mobile phones, the transition from a single ringtone to a polyphonic ringtone has been completed. This involves the audio synthesis system, which is mainly composed of audio sequencer, music synthesizer, and sound source circuit. For commonly used audio sequencers, usually a piece of music will be placed in the music event data buffer of the audio sequencer through a sequence of data in a format, and then the music playback data will be sequentially output for instructions for synthesizing music. Then it is played out through the music synthesizer and sound source circuit. In this way, if the user wants to change a piece of music, he can only change the content of the origin...
