I'm pretty sure that gramofile uses record to capture audio. Gramofile adds 
post processing with a number of standard filters to reduce noise, such as 
what you get from a scratched LP.

IIRC, lame is a front end to bladeenc. I haven't used lame, but I've been 
quite happy with bladeenc. It's a simple, command line program, called 
thusly:

 bladeenc [global switches] input1 [output1 [switches]] input2 ...  

I don't remember what the switches do; all I use is:
 
 bladeenc INPUT1 OUTPUT1 -br 256000

You can set the sampling rate to what you prefer. Our music collection is 
mostly classical, and we weren't happy with the lower rates. On the other 
hand, we couldn't tell the difference between 256000 and 3xxxxx (I forget 
what CD quality is, but it starts with a 3, and has six digits!). Saves a 
little space without noticeable loss of quality.
