This one is a bit difficult to explain .
I am recording from the integra straight into the audio recorder over usb .( no line input device )
I route the signal ( from the sample recorder dropdown ) through a track thats has klanghelm VU meter on it ( and thus record the output ) , the average db VU is of no relevance here
When renoise pre-mixer headroom (song options ) is set to -6db , the input signal is lowered by 6db before going into klanghelm vu meter .
NOw ,I adjust the input trim on the plugin ,and it peaks at -6dbfs (full scale that is , NOT VU) so no hard clipping whatsoever , while the record dialog /recorded signal obviously clips
When setting track headroom to 0db , renoise recording signal mimicks the klanghelm vu meter ( peak level )..iow it's correct .
So , have to say I'm a bit confused myself , the recording is the output of the plugin( klanghelm ) but without headroom .
Here are 2 screenshots , focus on the number in the right hand corner , that's the db ffull sclae mode .= above odb is clipping .
The db VU meter is of no importance , only the peak db value
