<\/p>\nIn previous releases, the streaming and probe point queue memory was always allocated to the maximum size. This “problem” has been solved by adding a new configuration to the virtual cores. From the S release onwards, the user can configure whether live streaming is required and how many probe points are needed. According to these settings, xAF will allocate the memory for the ProbePoint queue.<\/p>\n
If unchecked, no memory is allocated in the AudioCore class, i.e. no instance of the ProbePoint queue is created. A value of 0 will only allocate memory for state variable streaming, resulting in 2 * 16 * 4 = 128 bytes (safety factor * max state variables * sizeof(float)). For each enabled probe point, the queue is increased by the largest block length used in the xAF instances, multiplied by sizeof(float).<\/p>\n
<\/p>\n
The streaming data is queued in the audio cores owned by ProbePointQueue and must be unqueued by the platform according to its preference.<\/p>\n
Option 1:<\/span> Create a separate thread that is called whenever the CPU is not busy with audio processing. The tricky part here is to ensure that this thread gets the right priority to send its data, which is not an issue for state variable data, but could become a challenge with audio probe points.<\/p>\n Option 2:<\/span> Call dequeue immediately after AudioCores calc has been executed. This is the preferred option from a Windows perspective, as the timing is difficult to handle on Windows while using blocking socket calls.<\/p>\n An example for both options can be found in the VstInOutRouter in the awx_winpc repository<\/p>\n","protected":false},"excerpt":{"rendered":" In previous releases, the streaming and probe point queue memory was always allocated to the maximum size.
