MB STUDIO shows the indication of the memory and handles used by MB STUDIO. This is not the general free memory of the computer, but the free memory available for MB STUDIO. They are important values that help understand if some component or function is consuming too much memory. To make a comparison, a car engine will turn off when the petrol runs out just as MB STUDIO will stop working when the free memory is used up.
The H: handles are numbers that the system uses to manage an object or other structure, they must never exceed 10,000 otherwise MB STUDIO will restart automatically. A: Indicates the number of audio features in use (usually should not exceed 50). V: indicates the number of video functions in use (usually should not exceed 5)
Free memory is allocated by Windows. This value does not refer to your computer's memory, even if you have 64 GB of memory in your Windows computer, it initially assigns 3.5 GB to MB STUDIO (i.e. 3548 MB). When the indicator drops below 300 MB the indicator turns red to indicate that memory is running low.
While using MB STUDIO it is absolutely normal to see free memory decrease and increase. However, if the memory continues to constantly decrease until it runs out then something is wrong with MB STUDIO (a DSP/VST or VLC component consumes too much memory).
