Abstract
A digital audio signal generating apparatus suitable for the application to electronic musical instruments, sound effect generators for amusement machines and the like. This digital audio signal generating apparatus has a signal processing section and a memory used to perform a speech synthesis, wherein the signal processing section utilizes a vacant area of the memory to perform a delay processing to add a reverberation sound. Thus, the number of required memories can be reduced and the arrangement of the apparatus can be simplified.
Claims4
An apparatus for generating a digital audio signal comprising:
- memory means for storing a digital audio signal;
- control means for controlling a reading the digital audio signal from the memory means;
- signal processing means for performing a predetermined processing, including reverberation processing, of the digital audio signal read by the control means;
- temporary memory means used by both the control means and the signal processing means;
- and
- means for setting a delay area in vacant areas of the temporary memory means so as to perform a delay processing when a reverberation sound is added to the digital audio signal processed by the signal processing means.
