Much can be said about the use and function of Compressors and limiters. I am using two BOSS PRO CL-50 units which are very nice units with very good distortion figures. A comment was made to me from Europe the oter day about just how brilliant the audio was coming out of SAM V4. I surly have to agree with. This company has audio processing that is pretty hard to duplicate with off the shelf equipment. Congratulations must go to there South Africain Programmer who has done the job. The sounds even from tired old MP3 tracks is astounding.
