That’s an intriguing idea. The psychoacoustic maskers do give you a window to slip in extra data, but the trade‑off is brutal—every tweak in the quantization steps shows up in the spectral envelope, and a quick psychoacoustic analysis can flag anomalies. If you’re going to use it, keep the payload small, spread it across multiple granules, and test it against a range of decoders to make sure the hidden bits don’t trigger the bit‑error checks. It’s a neat playground, but a lot of fine‑tuning is needed to stay below the detection threshold.
