MarsSeed [1] filed a deletion request for lib32-spandsp [2]: This "DSP library for telephony", originally submitted to AUR in 2013 for feature-parity of lib32-gstreamer with repo's counterpart, is not needed anymore by that package. Nor, reasonably, by any 32-bit-only application. Also it is too new for such a scenario. (First released in 2007; Linux has supported x86-64 since 2001, and anyhow this is a niche software component.)
