【Open-Source】Reverb at Echo Control para sa Mixing Console Microphone Batay sa T5L

——Mula sa DWIN Developer Forum

Ikinalulugod naming ipakita ang isang award-winning na open-source na case mula sa DWIN Developer Forum ngayon: reverb at echo control para sa paghahalo ng console microphone batay sa T5L chip. Gumagamit ang aming engineer ng 800x480 na resolution na display para makipag-ugnayan sa reverb development board sa pamamagitan ng UART 4 ​​ng T5L, na nagbibigay-daan sa tumpak na pagsasaayos ng mga kritikal na parameter ng audio gaya ng reverb, echo, wet sound, dry sound, acoustic, decay at delay para sa superior audio effects.

(1) Ang pangunahing programa para sa screen ay ang mga sumusunod:

void main(){

INIT_CPU();//System Initialization

PORT_Init();//Initialize ang IO port

T0_Init();//Initialize ang timer 0

T2_Init();//Initialize ang timer 2

my_UART4_Init(115200);

uart_init();//Initialize ang serial port

ws2812_writ_byte(8);//Initialize ang LED light

RetMicSet();

delay_ms(1000);

habang(1){

Uart_Handle_all();

OneMsHandle();//1Ms sa bawat oras

TenMsHandle();

Read_0xF00();//Awtomatikong pag-upload ng data

}

}

}

(2) Ang mga parameter na nauugnay sa reverb ay ang mga sumusunod

#kung 1

intreverb_parameter_val(u16 basa,u16 tuyo,u8 diffusion,u8 decayfactor,

u8 is_bypass, u8 idmode)

{

#if tinukoy(TCFG_MIC_EFFECT_ENABLE)&& TCFG_MIC_EFFECT_ENABLE

#kung 1

u8 mode_id = idmode+5;

Plate_reverb_TOOL_SET *parmt = &eff_mode[mode_id - mic_mode_seq0].plate_reverb_parm;

parm->parm.wet=basa;

parmt->parm.dry=dry;

parmt->parm.diffusion=diffusion;

parmt->parm.decayfactor=decayfactor;

parmt->is_bypass=is_bypass;

plate_reverb_update_parm(&parmt->parm, parmt->is_bypass);

#elif 1

u8 mode_id = idmode+5;

//memcpy(&eff_mode[mode_id - mic_mode_seq0].echo_parm,&packet->data[1], sizeof(EF_ECHO_TOOL_SET));

EF_ECHO_TOOL_SET *parmt = &eff_mode[mode_id -mic_mode_seq0].echo_parm;

parmt->parm.delay=delay_ms;

#elif 0//PARM_DEBUG

log_debug("delay%d, decayval %d, filt_enable %d, lpf_cutoff %d, wetgain %d, drygain %d\n",

parm->delay, parm->decayval,parm->filt_enable, parm->lpf_cutoff, parm->wetgain, parm->drygain);

#endif

#endif

bumalik 0;

}

 

(3) Ang mga parameter na nauugnay sa echo ay ang mga sumusunod:

int Echo_parameter_val(u16 basa,u16 tuyo,u16 delay,u16 decayfactor,

u16 is_bypass, u16 idmode)

{

#ifdefined(TCFG_MIC_EFFECT_ENABLE) at&TCFG_MIC_EFFECT_ENABLE

#ifTCFG_MIC_EFFECT_SEL==MIC_EFFECT_REVERB_ECHO

u8 mode_id = idmode+5;

EF_ECHO_TOOL_SET*parmt = &eff_mode[mode_id - mic_mode_seq0].echo_parm;

parmt->parm.wetgain=wet;

parm->parm.sixty=dry;

parmt->parm.delay=delay;

parmt->parm.decayval=decayfactor;

parmt->is_bypass=is_bypass;

echo_updata_parm(&parmt->parm, parmt->is_bypass);

#endif

#endif
