Hi Lavry. When the "big guys" clip their converters it seems like it's an artistic choice that makes the sound more edgy and creating the illusion that the musicians are playing more edgy "with a bad attitude" than they really are. My gues would be that the sound they are getting needs the AD chip clipping to get like that and a limiter(or other circuitry) probably can't do it. |

This is a great example of the insane mental gynastics that some people go thru to convince themselves that something that sounds like sh*t actually sounds good. |

As stated earlier, I did that tape like saturation because I wanted to offer a "compromise" for those that just wanted to push thing to the clip point and beyond. As far as I know, clipping does a lot more than make things edgy. Some people say it ruins the image, but that is a sonic comment, and I rather stay on technical side of the issue. The comment about the AD doing the clipping: Remember that a clipped signal contains huge bandwidth and clipping in the wrong place can cause a lot of aliasing. Processing the signal either before or after the AD can be done with much less aliasing. Also, with sigma delta AD's you really do not want to get to a limiting point. The user does not know it, but the front end of the AD (the modulator) is still in its active region even if the digital output is already clipping. That extra margin is there to try an avoid the sigma delta modulator from losing it's tracking. If you push too much signal and run over that margin, you have to re establish proper operation. It is similar to having to reset your gear. In fact some chips do reset the modulator and it takes time, thus pretty noticeable... BR Dan Lavry |

As in "clipping". A big "left handed compliment"! BK |
