* OUT lp_coeff[0,max_order-1][0,max_order-1] LP coefficients for each order
* *** IMPORTANT:
* *** lp_coeff[0,max_order-1][max_order,FLAC__MAX_LPC_ORDER-1] are untouched
- * OUT error[0,max_order-1] error for each order
+ * OUT error[0,max_order-1] error for each order (more

* Example: if max_order is 9, the LP coefficients for order 9 will be
* in lp_coeff[8][0,8], the LP coefficients for order 8 will be
