AEC APIs
重要
The AEC API v1.0 is the lastest stable AEC APIs. All new applications should use AEC API v1.0.
AEC API Categories
- AEC APIs:
aec_size()
- get AECContext size (byte)aec_init()
- init aec moduleaec_ctrl()
- get and set aec parametersaec_proc()
- excute aec function
API Reference
Header File
Functions
-
uint32_t aec_size(uint32_t delay)
Get AECContext size (byte)
- 参数
delay – delay samples
- 返回
uint32_t: size(byte)
-
void aec_init(AECContext *aec, int16_t fs)
Init aec.
This API init aec function :
Set aec parameters
Init fft parameters
Usage example:
AECContext* aec = NULL; //malloc aec memory aec = (AECContext*)os_malloc(aec_size()); //init aec aec_init(aec, 16000);
- 参数
aec – aec parameters
fs – frame sample 8K/16K
- 返回
none
-
void aec_ctrl(AECContext *aec, uint32_t cmd, uint32_t arg)
Control aec.
This API control aec function :
Set aec parameters
Get data addr
Usage example:
AECContext* aec = NULL; //malloc aec memory aec = (AECContext*)os_malloc(aec_size()); //init aec aec_init(aec, 16000); //set mic delay aec_ctrl(aec, AEC_CTRL_CMD_SET_MIC_DELAY, 10);
- 参数
aec – aec parameters
cmd – control command in enum AEC_CTRL_CMD
arg – value
- 返回
none
-
void aec_proc(AECContext *aec, int16_t *rin, int16_t *sin, int16_t *out)
Control aec.
This API control aec function :
Set aec parameters
Get data addr
Usage example:
AECContext* aec = NULL; //malloc aec memory aec = (AECContext*)os_malloc(aec_size()); //init aec aec_init(aec, 16000); //aec excute work aec_proc (aec, rin, sin, out);
- 参数
aec – aec parameters
rin – reference data
sin – source data
out – output data
- 返回
none
