Hey hey, first of all, I love these filters! Thank you Rory and Victor! I have one issue, normally I work with linear scale amp (0-32768). In this mod every signal passed through mvclpf will only produce output of amplitude 1, which is unexpected and not very useful in that context. With 0dbfs =1 set in the header everything works just fine. Is this a limitation of the code as it was adopted or can it be changed to accept both scales easily. I do like the audio control inputs! Thanks again!

unds like the output should be multiplied bu 0dbfs, and possibly inout divided? On Thu, 14 Jan 2016, Ffanci Silvain wrote: > Hey hey, > first of all, I love these filters!

yes, it looks like the case. I will modify the code. ======================== Dr Victor Lazzarini Dean of Arts, Celtic Studies and Philosophy, Maynooth University, Maynooth, Co Kildare, Ireland Tel: 00 353 7086936 Fax: 00 353 1 7086952 > On 14 Jan 2016, at 13:49, jpff |

I'm confused by this, why shouldn't it just be [-1.0,1.0]? If users want to use different values, they could scale themselves. If a user is using 0dbfs = 1, then they can avoid a multiply and divide. On Thu, Jan 14, 2016 at 9:50 AM, Victor Lazzarini |

I think it is better not to constrain. This was also the case with moogvcf, and we fixed it. I think we should try and work with signals in the 0dbfs range as much as possible. ======================== Dr Victor Lazzarini Dean of Arts, Celtic Studies and Philosophy, Maynooth University, Maynooth, Co Kildare, Ireland Tel: 00 353 7086936 Fax: 00 353 1 7086952 > On 14 Jan 2016, at 14:54, Steven Yi |

And al over thephysical models we do this On Thu, 14 Jan 2016, Victor Lazzarini wrote: > I think it is better not to constrain.
