Hi Dan - before i get to ball breakin,thanks for putting up with us - hope to learn a shitload. I've read that certain Plug-Ins perform better at high sampling rates - contrary to your report on your website re: Nyquest. are these people just full of non-sense ??? and just imagining ?? or do plug-ins benefit from hi sample rates ??? tenx |

Actually, Dan has supported the need for non-linear processing at higher sample rates to minimize problems with aliasing. There has been an AES Journal article on the subject. The problem is well known. BK |

I was originally confused by Nyquest theory because it's natural to assume that if the frequency of a sample can be represented, meaning that the actual frequency of the sound is maintained, then the sampled sound must sound the same as the original. Which, of course, is not necessarily the case. |

My questions would be: How many samples are used to represent a 20K Hz frequency sound at 44.1 Khz sample rate? |

Does that number of samples accurately describe all of the characteristics of that 20K Hz sound in its original continues form? |

Does it seem likely that in a good listening environment, most people could hear the difference? |

If you read my paper “Sampling Theory” you will see that I made an clear distinction between the sample rates used for storage and transmission of digital audio, and LOCLIZED sample rates, for a specific task. BR Dan Lavry |

Dan, is there a link where I could find your papers? Thanks, Nathan |

It seems that with Wavelets, plug-in manufacturers should be able to emulate the non-linear characteristics of analog gear very well. |

Do you think that this is happening? |

The popular opinion seems to be that plug-ins do not accurately emulate the non-linear charecteristics of analog gear. |

It also seems like much of modern commercial music is sterile sounding. |

Do you think this may be caused by the use of plug-ins that only emulate gear in a linear manner and/or may not be adaptive to the waveform like analog gear is adaptive to the signal? |
