mp3 - Extracting MDCT coefficients for steganalysis? -


mp3stego (http://www.petitcolas.net/steganography/mp3stego/) hides data within mp3 files during inner_loop , uses part2_3_length modify bits.

i'm wondering whether worth extracting mdct coefficients , examining them histogram compare mp3 file no hidden data in it. however, encoding process of mp3s mdct happens before inner_loop.

would there use of extracting coefficients if case? if so, best way of doing print out data file during encoding process?

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.
