<a href="http://opus-codec.org" target="_blank">opus-codec.org</a> site. The site indicated that the test files are intended for verifying that the Opus decoders are operating properly. I assume I could also use them to verify my encoder implementation, right?
For example, use testvector01.dec as input to my encoder and compare its output bitstream with the corresponding testvector01.bit bitstream file.<o:p></o:p></p>
