[Csnd] brick wall limiter

Hello Csounders, Does anyone have any examples of a good brick wall limiter. I've been experimenting with the dam opcode, but I can't get the signal to fall fast enough. Is seems like commercial limiters have a near instant "fall time". Am I missing some trick to accomplish this?
Thanks Thomas

i've always wanted to try non-linear transfer functions like 2*atan(x)/3.1415927 for 0dbs=1.0 k. On 01/13/12 14:43, Victor wrote: > Clip opcode ? > > > Sent from my iPad > > On 13 Jan 2012, at 19:41, Thomas Hass |

I'm not an expert, but I believe the commercial limiters use some sort of "look-ahead" to calculate what needs to happen in terms of attack and release.

Hi Thomas, I don't use limiters very much, but I remembered these filters by Eric Spjut: http://www.csounds.com/spjut/index.html Also, have you tried compress: http://www.csounds.com/manual/html/compress.html steven On Fri, Jan 13, 2012 at 2:41 PM, Thomas Hass |

Yes, I've been experimenting with compress quite a lot. I've gotten decent results with dam used in combination with the transfer function that Kelly described. However, the best I can manage so far is to ease the clipping until dam brings the signal down to a suitable level. I'll keep experiment with dam and compress and report back if I get any better results. Thanks for all the pointers! Thomas

Can someone explain the numbers in this formula? I've found it quite useful but I'd like to know why use these specific numbers.

Arctangent is a trigonometric function that by its nature produces an angle in the range -pi/2 to +pi/2, where pi is the ratio between circumference and diameter of a circle. Dividing by pi and multiplying by two gives a result in the range -1 to 1, which is convenient. The number 3.1415927 is a reasonable approximation of pi, whose true value is an irrational number. |
