Abstract
The invention is applied in the field of audio processing and provides a sound accompaniment output control method, a sound equalizer and audio play equipment. The method comprises the following steps of: receiving a volume-adjusting command of a user; according to the volume adjusted by the user, identifying a sound accompaniment parameter which corresponds to the current volume; reading the sound accompaniment parameter which corresponds to the current volume; and outputting the sound accompaniment parameter which corresponds to the current volume to a power amplifier. According to the magnitude gain of the sound accompaniment volume, the output of the sound accompaniment is controlled by selecting the corresponding sound parameter; when the volume of the sound accompaniment is low, the user can still have the live feeling; and when the volume of the sound accompaniment is high, the distorted frequency points are reduced, so that the sound is more clear and pure, the audio layer feeling is stronger and the sound effect of the audio play equipment is improved.
Description
Technical field
The invention belongs to field of audio processing, relate in particular to a kind of sound accompaniment output control method, sound equalizer and audio-frequence player device.
Background technology
The acoustic processing technology that is applied in the existing system for TV set has many, for example Chang Yong high pitch, bass etc.These treatment technologies have been realized the lifting of sound quality by whole sound frequency range is handled, and have satisfied user's hearing enjoying on certain degree.
The sound of different frequency ranges has different characteristics, suitably strengthen or reduce the gain of a certain frequency, can realize different sound effects, for example the sound of 20HZ～60HZ frequency range influences the spatial impression of tone color, the sound of 60HZ～100HZ frequency range influences sound mixedly shouts sense, it is the frequency zones of bass, the sound of 300HZ～500HZ frequency range can show the thickness and the strength of voice, the dynamics of 800HZ frequency range performance sound tone color, the sound of 4K～8K frequency range influences the definition that the people speaks most, lightness, the sound of this section of 12K～16K frequency range can influence whole color sense
Because the amplitude of the input signal of television sound is different, the sound accompaniment amplitude difference of video disc is bigger, in order to solve the differentiation of television audio input range, utilize the equalizer of the television set tone of keeping company whole, when small volume, can satisfy, but when different volumes, can reduce sound effect greatly, distortion is too many, can not better meet user's hearing enjoying.
