# By default, lame uses constant bit rate (CBR) encoding. 
# You can also use average bit rate (ABR) encoding, 
# e.g. for an average bit rate of 123 kbps:
lame --abr 123 input.wav output.mp3
		
		

		
# or variable (VBR) encoding, e.g. between 32 kbps and 192 kbps:
lame -v -b 32 -B 192 input.wav output.mp3
