First, you must have “lame” program. If the programe “lame”is currently not installed. you can install it by typing in consule : sudo apt-get install lame

second, after the program “lame” is currently installed. you can use it for decrease mp3 bitrate.

format :

lame -b [bitrate] input.mp3 output.mp3

CPU features: MMX (ASM used), SSE, SSE2
Resampling: input 24 kHz output 16 kHz
Using polyphase lowpass filter, transition band: 5484 Hz - 5677 Hz
Encoding input.mp3 to output.mp3
Encoding as 16 kHz 32 kbps j-stereo MPEG-2 Layer III (16x) qval=3
Frame          | CPU time/estim | REAL time/estim | play/CPU |    ETA
4613/4613 (100%)|    0:08/    0:08|    0:09/    0:09|   20.604x|    0:00
