Hi, Yes, I think you can use the Adaptive Silence Detection [1], and create a simple media port just to filter the silence before the file writer, and perhaps a simple counter to decide if EOF is reached (after some contiguous silence frames). Here is a sample diagram: input (e.g: audio dev/file reader/conf bridge) -> custom media port (with silence detector) -> file/mem writer.
