Audio APIs

================

|
The Audio API v1.0 is the lastest and stable Audio APIs. All new applications should use Audio API v1.0.
|
||
|
|
|
||
|
|
Audio Interface
|
||
|
|
----------------------------
|
||
|
|
|
||
|
|
The BK Audio Driver supports following functions:
|
||
|
|
|
||
|
|
- adc function
|
||
|
|
- dac function
|
||
|
|
- eq function
|
||
|
|
|
||
|
|
The adc and dac function can be operated independently. However the eq function need to use with dac function together.
|
||
|
|
|
||
|
|
Audio API Categories
|
||
|
|
----------------------------
|
||
|
|
|
||
|
|
Most of Audio APIs can be categoried as:
|
||
|
|
|
||
|
|
- Common APIs
|
||
|
|
|
||
|
|
The common APIs are prefixed with bk_aud, the APIs may be common for adc and dac interfaces, e.g. bk_aud_driver_init() etc.
|
||
|
|
|
||
|
|
- Adc function APIs.
|
||
|
|
|
||
|
|
The APIs provide support for adc function. e.g. bk_aud_adc_init() etc.
|
||
|
|
|
||
|
|
- Dac function APIs.
|
||
|
|
|
||
|
|
The APIs provide support for dac function. e.g. bk_aud_dac_init() etc.
|
||
|
|
|
||
|
|
- Eq function APIs.
|
||
|
|
|
||
|
|
The APIs provide support for eq function. e.g. bk_aud_eq_init() etc.
|
||
|
|
|
||
