WebOn the basis of the clock cycle counter information and the audio frame size, the software calculates the Hz used to encode and decode 1 second of audio with the selected Opus configuration. You can compare the selected STM32 system clock with the profiling results and decide if that particular Opus configuration is suitable for your WebJun 2, 2024 · This counter is incremented every CPU cycle (i.e. 168 million times per second). Whenever the CYCTAP bit in the cycle counter is toggled (0->1 or 1->0), we decrement a counter which started at the POSTPRESET value. When that counter hits 0, a PC sampling event is generated. lake animal adaptations https://distribucionesportlife.com
