Hi,
Looking for spectral-flow-detection in some kind of omsupervp library. Does somebody knows which version ?
Thanx
K
Thx guys,
found it !

Hi Karim,
Is this not the scope of the transient detection with the segmentation type on spectral differencing -/+ ?
I’ve checked the supervp -ht in the terminal and compared the list of flags in the lisp code of the transient-detection function (OMsuperVP)…
(transient-params (format nil “-OT -td_thresh ~D -td_G 2.5 -td_band ~D,~D -td_nument 10.0 -td_minoff ~Ds” treshold minfreq maxfreq minoffset))
Well, FIRST there is no sign of the -td_minren :
minimum relative energy difference an attack has to produce to be
detected as an attack. The relative energy difference is calculated
as the energy difference between the transient bins after the
attack and before the attack normalized by the total energy
difference.
Which nearly corresponds to the A.S. online doc :
Positive and Negative Differencing
Positive spectral differencing detects a quick increase of energy, as in the case of an attack for instance.
Negative spectral differencing detects a quick decrease of energy, as in the case of the end of a note. </i>
nevertheless in the output sdiff file from the process with the transient-detection function (.omp file attached) there’s a reference to :
1TYP
{
1MTD XTRD {rel_energy_diff, rel_maxamp}
1FTD 1MRK
{
XTRD transient_descriptor;
}
}
Is it a mixed process ?
I Hope it helps

I haven’t seen your monologue :))
the repetition of these posts are still a mess !
Dear Nadir,
Yes it’s something like that but implementated in Om. Thx anyhows. I got it.

Dear Karim,
You’re welcome.
What implementation in OM it is ?
N.
It is a written lisp code starting from the omsupervp lib. It’s a kind of fix i made.
