Possibly the closest you get atm is setting up Snd
(https://ccrma.stanford.edu/software/snd/) as an inferior scheme
process, and control it from emacs via existing major or minor-modes, or
build further to integrate more tightly into eg. dired.  Everything in
Snd is controllable and accessible from a running scheme.

Linking in libsndfile, which is rather x-plattform i beleive, would
provide builtin access for reading (and writing) the various sound-file
formats around.

A project id like to get going is setting up a database type app for
sound - something similar to various photo-managers - where info from a
sound gets stored and managed - diskfile, region, format, tags and
metadata of all sorts - - and made available through a general
interface.  Send a query to find certain regions from some files, and
ask a running sound-editor to show them.  Edit them, update metadata
info, headers etc. on a set of matches (ie. add a tag or similar) etc.

Ideally an interchange format (SDIF?) would make exported data usable by
all sorts of clients, import into your DAW, export a region into a
soundeditor and get the edited version back w. updated metadata...

Emacs would be an ideal environment to access all this.
