software > Right-Click MP3
Introduction
Right-Click MP3 is a nice little tool to encode .wav into mp3. It adds a shell extension so that when you right-click a .wav files,
you get the option to encode it in .mp3.
You can specify the bitrate up to 320kbps. It's has been years and I'm still satisfied with this 8 years old program (dates back 1999).
The version I tried is v1.65. It uses BladeEnc v0.82 to encode in CBR or Xing v1.5 to encode in VBR
