Hi Chris,what "limiting strichnes" controls and whats the best value ??? Maybe I should rename it to 'Limiting aggressiveness'. Basically, if you set it higher, it limits much stronger - at the risk of causing artifacts (even if in the end it doesn't result in a lower peak level!) If it doesn't limit hard enough, you'll get spikes, which will have to be removed by Hard Limit, causing both some artifacts and a drop in output level. I've found that at '10%' it limits nearly as good as at 100% (so causes nearly no extra Hard Limit artifacts), except for 'difficult sounds' such as xylophones - those rare sounds can then be handled by Hard Limit, causing a (very small) drop in volume instead of artifacts, which is good. I haven't really tried different values, so maybe 9% or 11% is better, or maybe even 5% is as good as 10%... So I still need to tweak this value. |

Nothing interesting has changed. There was a minor issue with the new 'S' handling algorithm. I've fixed that now, result is a slightly (upto about 1 dB) bigger volume drop of mid frequencies during loud 'S' sounds, but less distortion. I don't know if the current setting (100%) is good or now - still need to check it. (Feedback is of course welcome; it's probably also a matter of taste).

hmm .. +200 is still ok... must check it tomorrow again.. edit: What is this 'artifact' at ~58kHz, it's there for some time. |

I don't see anything? How/where/when?

ST Standalone, Vac 192kHz output, RDS Off, ... Mostly caused by lows. edit: Highs are somehow too much closed by loudness.. Maybe this is intentionall but there is room to 100% to be nicely clipped by loudness and hard limit to around 98% - currently avarage for loud 's' is 90%. (fm mode - testing) |

Eh, what do you mean exactly? The highs should fill up everything to around 100% just like any other frequency - and as far as I've seen they do. How did you see/measure this 90%? That would be quite a big drop... |

1. Actually sometimes i see it in ST graph too.  2. Picture with loudest 'S' sound, (any highs same). This is even with Composite limiter at 105%. so boosted bit... It's around 90% .. insted to be around 97-98 (can't know that now) .. it's going into volume drop. Seems "HARD LIMIT" is doing part of this too.  (fm-mode!) |

edit: What is this 'artifact' at ~58kHz, it's there for some time. Can also see it a bit. Seems like a 3rd Harmonic of the 19KHz , meaning 57KHz Changing RDS output to 0% doesn't solve it. Can you try that Mr Bojcha if it is the same? |

Hi Luke.. It's more 58kHz .. you can see (and measure) on pic.. http://img824.imageshack.us/img824/8797/24492270.jpg |
