| REVISION HISTORY |
| |
| Description: Modified to return the LPC coefficients in-place, so the |
| interface to tns_decode_coef is changed. |
| |
| Description: Modified to return the q-format of the LPC coefficients. |
| |
| Description: Modified so that only the function is declared here. extern |
| references to constant tables removed. Also, new copyright header included. |
| |
| Description: Modified to include extra parameter, so tns_decode_coef can use |
| scratch memory techniques. |
| |
| Description: |
| (1) Modified to include the lines... |
| |
| #ifdef __cplusplus |
| extern "C" { |
| #endif |
| |
| #ifdef __cplusplus |
| } |
| #endif |
| |
| (2) Updated the copyright header. |
