Embodiment 1
[0068] This embodiment provides a multi-segment dynamic range control method, which can be applied to any type of speakers or devices including speakers, for example, earphones, speakers, TVs, mobile phones, tablet computers, smart bracelets, personal digital assistants, notebook computers and other mobile terminals.
[0069] The multi-segment dynamic range control method includes:
[0070] Step S101 , accessing the left channel signal and the right channel signal, and adjusting the gains of the left channel signal and the right channel signal, to obtain a first left channel signal and a first right channel signal.
[0071] In a specific application, the left channel signal and the right channel signal can be obtained from devices or corresponding circuits that have the function of collecting and outputting audio signals, such as voice chips, microphones, and audio acquisition cards. The audio signal of the same channel can be input through a multi-segment dynamic range contr...
Embodiment 2
[0104] This embodiment provides a multi-segment dynamic range control method, which can be applied to any type of speakers or devices including speakers, for example, earphones, speakers, TVs, mobile phones, tablet computers, smart bracelets, personal digital assistants, notebook computers and other mobile terminals.
[0105] The multi-segment dynamic range control method includes:
[0106] Step S201, accessing the left channel signal and the right channel signal, and adjusting the gains of the left channel signal and the right channel signal, to obtain a first left channel signal and a first right channel signal.
[0107] In a specific application, the left channel signal and the right channel signal can be obtained from devices or corresponding circuits that have the function of collecting and outputting audio signals, such as voice chips, microphones, and audio acquisition cards. The audio signal of the same channel can be input through a multi-segment dynamic range contro...
Embodiment 3
[0141] This embodiment provides a multi-segment dynamic range control system, which can be any type of loudspeaker or a software program system in a device including a loudspeaker, such as earphones, speakers, TVs, mobile phones, tablet computers, smart bracelets, personal digital Assistants, laptops and other mobile terminals.
[0142] Such as figure 1 As shown, the multi-segment dynamic range control system 1 provided in this embodiment includes the following virtual devices that are simulated by software programs and have the same functions as physical devices:
[0143] Volume gain controller (Stereo Fader) 101, the first high-pass filter 102, the first equalizer (Equalizer, EQ) 103, the second high-pass filter 104, the first low-pass filter 105, the first dynamic range control circuit ( Dynamic Range Control, DRC) 106, second dynamic range control circuit 107, first signal adder 108, second signal adder 109, second equalizer 110, compressor (Compressor) 111, digital-to-an...
