Acoustic signal processing apparatus wherein pre-set acoustic characteristics are added to input voice signals

摘要

An acoustic signal processing device used in, for example, karaoke systems, includes a signal processor, a digital/analog converter and a mixer. The signal processor converts the input analog acoustic signal into a digital signal and processes the converted digital signal by signal processing for generating a digital signal added to with pre- set acoustic characteristics. The digital/analog converter converts the digital signal generated by the signal processor into an analog signal. The mixer mixes the input analog signal with the analog signal outputted by the digital/analog converter.
