Lame encoding from .wav to .mp3

I am no audio expert but given that the "ripping and encoding" tool I used to use "Grip" is no longer available within the Ubuntu repositories, I have had to resort to something else. Grip as an application has not been updated much since it was released and this along with other applications need to be continually bettered and updated. I liked "Grip" a lot and was saddened that it is no longer available in the Ubuntu repositories.
