Hi, all

Recently, I used straight(matlab version) to extract spectrum envelope from speech wave, for one frame, I draw a picture using 'plot', I am confused what y-axis stands for, what's the unit of y-axis, obviously, it's not DB,the x-axis stands for frequency.

the more details you can check my picture in the attachment!

Look forward your suggestions!

Thanks!
