No, that's not it. So I tried:
(def audio-context (js/AudioContext.))
(.decodeAudioData audio-context (js/ArrayBuffer. 256) #(println "ok" %)
#(println "error" %))
and it compiled to:
;var zv = new AudioContext;
zv.Rd(new ArrayBuffer(256), function(a) {
return fo.c(mh(["ok", a], 0));
}, function(a) {
return fo.c(mh(["error", a], 0));
});
This has really got me stumped.
