Abstract
Apparatus and method for reproducing a MIDI file are provided. In the apparatus and the method, notes and note reproduction times are extracted from the MIDI file and a difference between a start point and an end point in a Loop section of relevant sound source data according to the note reproduction time is detected and stored. The above stored difference between the start point and end point of the sound source data which will be reproduced is compensated and outputted, so that sound quality distortion in the Loop section is eliminated or reduced.
Claims12
An apparatus for reproducing a MIDI file, the apparatus comprising:
- means for extracting notes and note reproduction times from the MIDI file;
- means for storing sound source data;
- means for storing information of a start point and an end point in a Loop section of relevant sound source data according to the note reproduction time;
- and
- means for reproducing and outputting the relevant sound source data according to the start point and the end point on the basis of the note and note reproduction time.
The apparatus for reproducing a MIDI file, the apparatus comprising:
- a MIDI parser for extracting notes and note reproduction times from the MIDI file;
- a MIDI sequencer for sequentially outputting the note reproduction times;
- a sound source storage for storing sound source samples on the basis of a wave table;
- and
- a frequency converter for compensating a difference between a start point and an end point of sound source data which will be reproduced to reproduce and output the sound source data according to the note and note reproduction times from the MIDI sequencer.
A method for reproducing a MIDI file, the method comprising:
- extracting notes and note reproduction times from the MIDI file;
- detecting and storing a difference between a start point and an end point in a Loop section of relevant sound source data according to the note reproduction time;
- and
- compensating for a difference between the stored start point and end point of sound source data which will be reproduced and outputting the compensated sound source data.
