Est. Budget: $400.00
We're need a DirectShow filter that implements audio mixer. The filter should have up to 8 input pins and one output pin and should work with PCM / IEEE audio data. Filter interface needs to have amplification controls for the inputs and for output (use floating point values). Seeking must work correctly in graph edit tool. Custom output format can be set.
Filter with full source code required then all work is done. Binary version for testing.
