Add samples across all input streams.  
Adds samples across all input streams, i.e.:


output = sum(input[0], input[1], ..., input[M-1])
For all n samples on all M input streams x_m:
output[n] = sum( x_0[n], x_1[n], ..., x_m[n])


As this is a basic template, it's also in the [[:Category:Stub_Docs|"Stub Docs category"]]. Please improve it.

Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI.  Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately. The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.
This flowgraph uses an Add Block to generate the classic "dial tone".<br>

Add samples across all input streams.

For all n samples on all M input streams x_m: 

output[n] = sum( x_0[n], x_1[n], ..., x_m[n])
