The Buffer Size Viewer dialog lets you inspect the buffer sizes which your
host application is using.
If you are using Spectron at low latencies or with large numbers of bands, you may experience unusually high CPU usage. Spectron allows you to tweak several buffer sizes in order to optimize CPU usage for your host application settings. Some host applications make it very easy to see what your buffer sizes are, but it can be more difficult to determine in others. For that reason, Spectron provides this dialog to let you find out exactly what buffer sizes are being sent to the plugin.
To use this dialog, simply launch it by clicking the View Buffers button on the General tab of the Options screen. Then use the following controls:
Captured buffer sizes: This listbox shows the buffers you have captured thus far. The number on the left is the input buffer size, and the number on the right is the output buffer size. Note that the input and output buffer sizes will be equal in the Pro Tools, VST, AU and MAS versions of Spectron, but in the DirectX version if delay compensation is enabled then the sizes may differ. When tweaking buffer sizes, you're interested in the number on the left, which is the host application's buffer size.
Start/Stop: Push Start to begin capturing buffer sizes. Now each time a buffer is sent to the plugin, it will be added to the list of captured buffer sizes for you to see. Push Stop to stop capturing buffer sizes. Note that buffers are sent in very rapid succession to the plugin, and after 100 buffer sizes are captured, the capturing will automatically be stopped.
Clear: Clears the list of captured buffer sizes.
Copy: Copies the list of gathered buffer sizes to the Windows clipboard, useful for pasting into a support email if necessary.
