1 /*
2 * twamr-tseq-enc is a test program for our AMR encoder: it reads raw
3 * 16-bit PCM (matching 3GPP *.inp) as input and writes 3GPP *.cod
4 * format as output, allowing libtwamr encoder to be tested with the
5 * official test sequences.
6 *
7 * Both input and output are read/written in the host machine's
8 * native byte order.
