This is a spinoff from the Turntable speed stability thread. Here we can discuss the technical details and logistics of a future test LP creation and group buy. Especially:

- Signals of the tracks at both sides
- Tools for signal generation
- Selecting the mastering/pressing company
- Organizing group buy
- Options (half speed mastering, etc)
- Any other ideas

We could have a brainstorming what type of test signals are available on other test discs, what of them are useful, what is missing. I believe it should be a measuring tool, so e.g. L/R channel identification and the like are unnecessary.

Default Test LP group buy

We could do with a group buy of a new test record. Many of the existing ones are badly mastered or pressed

No sign that's the case here.......and, more generally IME, most test records start life fine and good. Perhaps with the exception of attention to hole size/centring.........

In case anyone is interested 180g hi-quality vinyl costs about $11@ at a min quantity of 100. One might also at least get someone's ear that the hole size/centering is important. If 20 folks are considering buying one test LP at $40-50 plus shipping a group buy of just what we want might make sense.

Just a thought, 20 members each get 5 copies at about $65 or so with postage.

I would have thought Jason might want to offer this in the store? Worth asking him anyway. The setup GZ use New mastering system GZ Vinyl seems particularly useful as you can visualise the grooves before cutting.

But yes I would stump up, given I am too young to have a stash of originals like you

I'm reminded of the film, 'A Might Wind' where they had a record pressed without a centre hole to save cost on a budget label.............

A Mighty Wind Official Clip - The Record Had No Hole - 2003 | Fandango MOVIECLIPS

But it would be an option to miss out the hole drilling stage, I suppose....

For my sins I'm a musician in a band, and last year we had a run of 1000 vinyl records pressed. Mastering was by Pete Norman at Finyl Tweak, and it really was a great job. It matters where it's done and who does it, for sure.

I should have put a few test tones in there..........

On the plus side, I still have 996 virgin copies of the same record for test purposes

I'd be happy to get my hands on a nice test disc. Freq sweeps, resonance tests, stereo separation tests and other things would be very nice to have. And 45rpm is of great importance to me also, 12" 45rpms <3

One time I talked to a local vinyl manufacturer VinylPlant and I got a quote for 12.16€ per disc for 100 and 4.98€ for 300. Includes DMM stampers, test presses, printed labels and sleeves, packing and packaging etc. The quote was for a nice music release, If fancy color printing and other goodies is to be discarded the cost could decrease a bit. Shipping is pushing the cost per disc to 20...30€ range regardless.

I have no idea about their machines technical specs though.

EDIT: GZvinyl seems to beat everything though, very fancy tech and prices ~

Test LP group buy
Maybe a DIY test LP is a keen idea. Worthy of its own thread, of course. If we can discreetly get other audio forums interested there should be enough demand to make the price reasonable.

One nice thing about an open source test LP is that we could publish the original signal files, as well as the mastered files - if that's a help.
