Hello, could you tell us what happened to the slopes for sound power, reflections and their DIs?

It is justifiable that you wouldn't have reference slopes because the research on the subject is lacking, but if there was a way to make it so that we could superpose slopes with our own parameters on the CEA chart that would be very helpful.

Annotations, trend lines and recommended zone a la vituix are back. There is now a menu that allow you to configure and style the graphs. Currently in test on the dev site.

Not necessarily: it depends if the % are linear or not and what it does model.

If it encode amplitude you are correct, if it encode power it could be 50%.

Merci Pierre - the Rogue Amoeba support team has been great with quick and helpful responses. I will ask them about the characteristics of the control.

Why if ASR and EAC both reviewed a speaker, EAC one is always considered the default? I would like to see the pref score for non default spin as well

You can see the score in the 1st tab. Edit: funny that not always the 1st tab has the scores calculated.

But I am also curious to know how the default score is chosen.

On spinorama.org where speaker measurements appear, under the 'Data & EQ' tab in the 'AutomaticEQ (IIR)' section, we find an instruction like this:

Set preamp gain to: -3.0dB.

I am using Rogue Amoeba's Audio Hijack's Parametric EQ plug-in, and I have inserted a Volume plug-in ahead of each PEQ instance. Volume adjustments appear as percentages and not as decibels. A 3 dB drop would reduce a 100% volume setting to 70.7%, so my corresponding volume setting would be 71%, correct?

Thank you for this great resource!

But maybe you’re right.
Just check it out: Listen to a piece of music or to pink noise.
Use the Dezibel X App for free.
Look, if your 71% setting is (e.g. in the peaks) 3 dB lower than 100%
Or is it just 1.5 dB?
Then use 50%

Default score is coming from the default_measurement in the metadata file. Since it is a manual process, it may not be the best choice.
The logic is supposed to be:
- if we have only 1 high quality measurement, that's the default. (and medium is better than unknown).
- if we have 2 or more high quality measurements, the oldest one is selected (premium to the first reviewer if you want).
Between 2 NFS measurements, i do not know if one is better than the other. It could also depend a lot on the sample.

P.

P.S.: remember that the score is only valid +/- 0.6 at least and thus last decimal is not really significant.

what I meant is something like this

I would like to see as much information as with the default one

Great website by the way, appreciate your effort!

ok ok

2 changes:
- in the ranking table, you get the score data for each measurement
- in the speaker view, you get the score data for each mesaurement even if not the default

great, thanks. your website just gets even better. would you like some more feedback?

I would like to ask why spinorama.org does not show distortion graphs. E.g. recently Amir measured C8C, but the distortion graphs are not included.

Distortion measurements are not part of the spinorama.

Yep, and what's more the way the distortion measurements are taken and presented are not standardized and so you can't really compare them between different sources.

 

[slaweks]

You could always treat them as something additional, as a link with a disclaimer.

 

[kyuu]

I think that's best handled as is: follow the link to the original review if you want to see information that's not part of the spinorama. Pierre can do whatever they feel is best, of course, but I don't think it necessarily makes sense as an additional workload.

Preference Rating is not part of Spinorama either, is it?

True enough, but it is computed from the Spinorama data.

There is no distorsion data mostly because Amir does not share them in the zip file he put in every review. I dont have the energy to scan them manually.
There are 2 options:
1. write a bit of ML that extract the data automatically from the picture. (not that easy to do reliably)
2. have a set of people that do the scanning (with webplotdigitizer for ex) and then it is easy for me to add the data.

sure. I can easily add stuff with Claude (or Gemini).

@pierre , only the "show annotations" box works on Firefox, neither the "show trend lines" or the "show recommended zones" tick boxes work. All three show by default, but it's impossible to remove trend lines or recommended zones.
