Determining ScriptNode Block Size?

[clevername27]

Am I doing this right?

1. Wrapping the whole network in a dynamic block.
2. Attach a widget to the block size parameter.
3. Compile the network and plugin.
4. Load the hard-coded network.
5. Run the plugin.
6. As I'm running it, try different block sizes.
7. When I find the optimal block size, replace the dynamic block with a fixed block.
8. Profit?

Thanks, I'm a little lost here…

@clevername27 You got it right. I've used this technique recently to compare the CPU consuption when using different block sizes.

@Matt_SF can you share a little about what you found. What is the impact over lower or higher block sizes on the cpu?

[Matt_SF]

@oskarsh In my case, I've used it in a simple compressor. But In my plugin, I have 16 channels, which can all use the same compressor.

Processing the signal using a block size of 1 uses a bit more CPU (around 2% instead of 1-1.5% in my case), but if all 16 compressors are activated, this can be quite a lot.

What I thought I could do is offer the user a "Hi-Quality" switch so he can choose how he wants the FX to behave, and save CPU.

@Matt_SF Ok that sounds interesting!

make sure you set your networks to suspend on silence this usually drastically improves the CPU for these kinds of fx.

@oskarsh yes indeed!
