◆ g722_decode_state_t
◆ g722_encode_state_t
◆ g722_decode()
Decode a buffer of G.722 data to linear PCM.
- Parameters
-
s | The G.722 context. |
amp | The audio sample buffer. |
g722_data | |
len | |
- Returns
- The number of samples returned.
◆ g722_decode_free()
Free a G.722 decode context.
- Parameters
-
s | The G.722 decode context. |
