[Speex-dev] Can Speex frame size be expand from 160 to 320 for NB?

[Dennis Liu]

Thank you so much for your quick reply.

It looks quite easy to change it. But, how about those codebook and excite
table? I notice them have been fixed as the length of 160.

Thanks again,
Dennis

spx_int16_t my_buffer[320];
speex_encode_int(encoder, my_buffer, bits);
speex_encode_int(encoder, my_buffer+160, bits);

done
