Abstract

The invention relates to the technical scheme of karaoke microphone audio signal processing, especially relates to a multitrack karaoke system. A audio signal of a microphone undergoes processing such as amplification, frequency shift, voltage limit, noise gating, delay, reverberation, sound effect and the like, and then is divided into five channels for separate 10-band equalization, gain adjustment and DA conversion and is sent to an adder. A digital audio signal is decoded by a DTS decoder and similarly divided into five channels for separate 10-band equalization, gain adjustment and DA conversion and then sent to the adder to be mixed with the microphone signal so as to output 5-channel signals. A bass channel after decoded by the DTS decoder outputs bass channel signals through separate 3-band equalization, gain adjustment and DA conversion. Therefore, the 5.1-sound-track karaoke system is formed.

Description

technical field [0001] The invention relates to a sound system, a karaoke sound system, especially a multi-channel karaoke sound system. Background technique [0002] Present KTV, karaoke sound system or stereo 2 channels, or the 2.1 channel system of stereo 2 channels plus subwoofer channel, can't show the scene sense of space on the hearing. [0003] The 5:1-channel home theater that supports 3D images has entered the family, and the real sense of space in the scene of 3D movies provides people with an unparalleled sense of hearing. However, the existing 5:1 channel home theater has no karaoke function, and can only play music and 3D movies. It cannot experience the real sense of space and shocking effect of karaoke like watching 5:1 channel movies, let alone realize it. 3D screen 5:1 channel KTV wonderful three-dimensional audio-visual feeling. Contents of the invention [0004] According to the 5:1 channel karaoke system described in claim 1, the purpose of the prese...
