^yo ano yun 60/40? and yes, i'll be protecting my eyes..i use magnifying glasses para di ko na kelangan lumapit pa..
anyway, since nasa usapan na din tayo ng audio formats, im surprised na wala pa ko naririnig o nag mention dito ng HE AAC formats..kung maliit na ang mp3 o aac formats nyo, mas malaki pa ililiit nyan(labo hehe) pag convert nyo to HE AAC hehe..yun nga lang, its another lossy format so expect a bit of messed up clarity on your audio..
ako, i use HE AAC v2..mas maliit pa sya..was able to convert a 5mb mp3 file to 800kbs haha..yun ang equivalent ng 128kbps mp3 sa HE AACv2..experimented on my 8GB iTouch and was able to stuff almost my entire library into it..problem is, im using a 2nd gen ipod touch and the processing and battery life took the damage playing those files..same will happen if you play the files in your android device..
