+# Lame MP3 与 Wav 互转
+
+## 安装
+
+    sudo apt-get install lame
+
+## 使用
+
+Fixed bit rate 128kbps encoding:  
+
+    lame sample.wav sample.mp3
+
+Fixed bit rate jstereo 128kbps encoding, high quality (recommended):  
+
+    lame -h sample.wav sample.mp3
+
+Average bit rate 112kbps encoding:  
+
+    lame --abr 112 sample.wav sample.mp3
+
+Fast encode, low quality (no psycho-acoustics):  
+
+    lame -f sample.wav sample.mp3
+
+Variable bitrate (use -V n to adjust quality/filesize):  
+
+    lame -h -V 6 sample.wav sample.mp3
+
+Streaming mono 22.05 kHz raw pcm, 24 kbps output:  
+
+    cat inputfile | lame -r -m m -b 24 -s 22.05 -- > output
+
+Streaming mono 44.1 kHz raw pcm, with downsampling to 22.05 kHz:  
+
+    cat inputfile | lame -r -m m -b 24 --resample 22.05 -- > output
