Info panel
The area at the bottom right is the info panel. It offers context-sensitive help and displays engine statistics.
Stats
This tab displays information about the current state of the Playtime engine.
Tempo buffer size (in blocks)
The current size of the tempo buffer in blocks.
The tempo buffer size determines how many audio blocks Playtime may look ahead in order to pre-render audio clips with the correct tempo and sample rate. It is influenced by the "Tempo latency" setting.
See Tempo latency.
Pre-buffered blocks playing (min)
The smallest encountered number of pre-buffered blocks among currently playing audio clips.
Pre-buffered blocks playing (avg)
The average number of pre-buffered blocks among currently playing audio clips.
Pre-buffered blocks playing (max)
The largest encountered number of pre-buffered blocks among currently playing audio clips.
Pre-buffer fallbacks so far
The number of times in which any audio clip’s dynamic pre-buffer couldn’t provide the desired pre-rendered audio content, but the static pre-buffer was able to provide it instead.
It’s normal that this rises when playing audio clips, especially when using "Immediate" start timing.
Pre-buffer misses so far
The number of times in which any audio clip’s dynamic pre-buffer couldn’t provide the desired pre-rendered audio content and even the static pre-buffer failed to provide it.
If this rises from time to time, it’s usually no reason to worry. Often the non-provided audio content lies within the count-in section of a clip, which is most likely silence anyway. However, if this continuously rises, it’s not good and you will might experience audio dropouts or even completely silent clips. In this case, increasing REAPER’s audio device buffer size and/or decreasing the sample rate might help. You can also try to increase Playtime’s tempo latency.
