If you are OK with moderately high bitrates, you might prefer something simpler like an ADPCM scheme. It's pretty damn easy to implement ADPCM, certainly a lot less math heavy than MDCT-based schemes, and they achieve good quality at a somewhat higher bitrate (I have no data, but I'd guess 200-250%~ish.)
