You meant digital filters per se? They're fundamental to sound reproduction, especially during D/A conversion. Most commercially available DAC products employ them, although hide deep in ICs or discrete ones. Even entry level chips like PCM512x/PCM5102 [1] offer selection between two filters plus de-emphasis. In fact you can create one on PC using SoX or similar, apply to data stream and then push to ALSA for example. Another typical use case that you might find relevant is digital room correction. My aim is to create facilities for a basic filter management: list all available filters (or filter sets) and select the current one. I think it makes sense to include these to MPD protocol as digital filters affect how sound is perceived by users no less than volume levels (which are handled by MPD protocol already). And such extensions will enable music players to simplify user experience.
