Use the "..." buttons to select your Lame.exe and the directory where encoded/decoded should be stored.
If you want to you also can change the Encoder's Thread Priority:
  • Idle: Lame only encodes/decodes when you do nothing with your computer. On the first sign of activity, Lame will pause.
  • Normal: Lame runs as a normal thread and shares available resources with other programs.
  • High: Lame will use more resources than other normal threads, but it'll still work in "cooperation" with them. (you may get lags in the Progress GUI)
  • Realtime: the highest priority available. Lame will use nearly all resources to do the job. (you will get display lags and it could also be hard to cancel Lame 'cause LAMEr's GUI runs just on normal priority)
If you check the "Always use source path(s) for de-/encoded files" box, each output will be placed into the directory where the source file is located.
