Mechanical Impedances are the counterforces seen by the cantilever (depending on the construction...) due to bearing stiffness. When these (mechanical) resistances are low, the compliance is high and the stylus can follow complex modulations. Simplified =) It is basically like a spring/damper...

That is the grade of sophistication i was talking about, thank you for the effort!

This is exactly like going through a pile of Test-Records :P You are working (labouriously) with what is given, but this is about what you could have :cool: Which is why i thought a well put-together list of tracks and their uses could simplify the matter in the future.

Hey guys, Are you tired of searching for "that" specific test record you need for "this" one test you want to conduct? Does going desperately through your pile of test LPs get you weird looks from your friends and family? Have you always dreamed of having that "one" test record that would...

I'd say that is because of the placement of the Speakers. A tweeter in your footwell is not exactly well positioned. And you rarely (ever?) find bigger speakers positioned in a way that would justify a coax solution. To not drift off-topic too much: I was at the show, and besides having a...

Out of curiosity: Which tracks from which Ortofon records are you exactly talking about @Balle Clorin ?

I did some work on my auto-crop script for the 1007 Records @JP . It now brings together both variants into one, which can be chosen as prompted. i know, this is not for everyone, but since many use 1007 Records, this should make life easier for those =) ''' This script will take your...

Depending on how accurate you want to be, just use an App like "RPM Speed and Wow". I have a 360° Disc that i used in the past. I just put it on the record, push the LP to the Pin in the 0° Position and make a measurement. Then you do 90° Steps and do the newton iteration from there (always take...

I am playing around with this Script to classify Test Records, i love the idea! I am getting spikes though which render the plot useless. I can sometimes find a "sweet spot" (by offsetting and limiting revs for the measurement) with no spikes, but on some records there are just too many. I will...

I absolutely understand why ;), then again - for me this is one of the most, if not THE MOST important parameter. I also had my fun with this. Taking numerical values at given points was my route for easier comparability and coping :p

How do you cope with having to setup the lot of them perfectly before making a final measurement with high confidence? Asking for a friend... ;)

I actually have around 20 versions of this since i tried a lot of stuff, and i can't remember which one got me closest before i justswitched to sweep start detection. As i said, this was not tailored for your script, so there were also approaches were i was looking for the start of the pilot...

That was before i had the right 2-C RIAA correction in place, which made a lot of things a lot more complicated. It should be easier now. We'll see what we can do about it in the future =)

You are absolutely right. I forgot that I changed the method at some point because of accuracy problems with the end of pilot recognition method! (I was working with spectral energy density) Its been quite some back and forth with those scripts. Pardon me =)

Hmmm. But that is what I do? The script detects the pilot tone, in this case 1kHz, and looks where the pilot tone ends. After doing this at the beginning and running I to problems (using spectral density for detection) I switched to 20Hz recognition. This is where it cuts first. THEN it uses...

With the way i acquired signals in the beginning of my tests i had quite the problems with this end-of-sweep detection. Mainly because the SNR was getting super low in the end until i repurposed a phono stage to match the 2 constant encoding of the 1007 Records. from that time is the approach to...

Automated pre-processing of recorded Test-Tracks Hey guys, i was working on something similar like the Measurement Script used here and faced the problem of being lazy. Cutting the recorded test tracks for my purpose by hand was just too much of a hassle, so i wrote python scripts to automate...

Last Unit i have a receipt for was around 7000€ - there was one or two options included and this was almost 10 years ago though.

The cable was already missing one of the connectors when I got it (I did not buy it!) That's why I carved the other one open to get matching connectors on it;) that's when I discovered this.

You are right ofc, but the measurement method aside, It would be interesting to check for any backwards effects, which in my opinion is the whole reason for the Bi-Wiring story. Then again, I am not stating it is acoustically better or not, this is out of pure academic interest. But I...
