Opus implemented on ARM processor
Hello,
I’m currently using the Opus encoder in an embedded device with a small ARM Cortex M4, compressing audio in real time and it works great. My implementation is similar to the application note from Texas instrument “Implementing OPUS Voice Code for TM4C129x Device”.
The next step in my application is to add voice activation capability in real-time while compression is in progress. Reading through the Opus’s documentation, I noticed the implementation of a VAD component in the Opus library. I was wondering if someone could redirect me to relevant docum...
