What is your LP recording process?

A friend at work sent me his. IMHO it's a little insane - but he's happy in the same way I do cross stitch I guess.

____________________________________
My LP mastering process.

Step 1. Clean the record first with a dry carbon fibre brush. This removes much of the fine dust that's on the surface as well as some that's buried in the grooves.

Step 2a. Clean the record with the Nitty Gritty record cleaning machine. This machine automatically applies a wet cleaner composed of distilled water with additives such as isopropyl alcohol, and then vacuums the solution removing the dissolved dirt and grime from deep within the grooves.

Step 2b. Apply an even spray of AM or equivalent anti static solution. Load LP onto the Nitty Gritty cleaner for one rotation in vacuum mode.

Step 3. Obviously play and record the LP to a 24/96 WAV file.


Hardware used

1. Rega P5 turntable. This is a high quality low resonance precision turntable and tone arm combination.
http://www.rega.co.uk/html/p5.htm
2. A high quality Audio Technica moving coil cartridge.
3. Krell KSP-7B preamp. This is a 1995 vintage high quality commercial preamp that's famous for its very high quality phone stage.
4. Roland 24 bit 96KHz capture device. This is a reasonably cheap but high quality audio interface using balanced inputs.

Production software used.

Some post production software (Audacity) is used to remove clicks and pops, however, this process is performed manually and always in the 24/96 domain. No software is used to automatically remove clicks and noise as this compromises the fidelity and adds unwanted distortions.
The manual click editing can take up to 20 hours of work per record.

DVD authoring

DVD Audio creator is used to create a 24 / 96 LPCM DVD master. This is playable on all DVD-R players and is much higher fidelity than conventional RB CD.


Listening.

Load DVD and enjoy.
My playback system employs an external high quality 24/96 DAC which is connected via the SPDIF output on the DVD player.
The playback amplifier is a pre + PA and is custom designed and built to the highest possible specifications. The speaker system is Infinity IRS modified with RAAL ribbon tweeters and a redesigned crossover using the highest quality passive components.

Cost of setup

1. Turntable and cartridge > approx $3000 new
2. Krell preamp > $2000 second hand on ebay
3. Nitty Gritty cleaning machine > $1000 new
4. Edirol audio interface > $400 new
5. Infinity speakers > 10,000 new (in 1995) plus $2000 for recent upgrades.
6. Custom built amplification > approx $3000 worth of components and hardware.
7. Cables and accessories > $350

All looks fine to me :)

But even done at It's best, the record will still sound better, but the CD/DVD produced will sound better than the retail CD equivalent provided the record It's ripped from is of good quality and a good production.

It does save wear on your precious record collection and that is a very good thing :D

I did that sort of stuff up until a couple of years ago. The de-clicking process finally killed all the pleasure for me. The 20 hours+ thing is no joke. Psycho-acoustics being what they are; a person will accept a few clicks and pops when playing an LP, but NOT when they are on a CD re-mastered from an LP. And the only way to get rid of those clicks is to locate and remove them individually. Professional audio editing software like Wavelab can make this task a lot easier with it's waveform replacement tool, but it's still a mind-numbing task.

Woah! There's someone like my friend at work! Errgh! Scary.

Yeah Dave was surprised when I knew about audacity and used it. I was stunned when he told me he was using it for this purpose. 2 hours for 40 seconds? Um, no thanks.

He disses the concept of commerical software to do this (like my Dad uses). He prefers to locate and remove individually as you mentioned.

I agree with your friend Cat', removal of pops & clicks with software automations is less than ideal even with Wavelab, the manual way is the only way.

My friend is very good at creating digital disks from vinyl, he has a unbelievable turntable that is custom built right down to the arms, but I prefer just to play my vinyl, sounds better.

He does get closer to capturing the original sound, more than everything I have heard, but it seems like it is impossible to get everything as it is on the LP.

I'll have to show my friend this thread. that sounds interesting datafast69

He also told me about this bargin LP he bought at Red Eye really cheaply which was some kind of direct recording from some famous sound lab (he thinks the people in the store may not have known what it was and so did not price it accordingly).

I'll have to ask him to write down his rave as I don't quite get it.

I was using my Pioneer turntables, a Behringer mixer and my PC.

Simply cleaned the record, played through turntable to mixer, through to PC via stereo Line in.

Got the levels right on mixer and then recorded with Wave Lab as one single WAV file.

Once this was done, would listen to file, remove any echo or click that didn't belong and then split into separate files and remove any between track gaps.

Process took as long as it took to hear the album x 3 and a bit.

*Play for two minutes to get levels right.
*Play all the way through whilst recording.
*Play recording to clear any artefacts in file.
*Play again to break into single tracks.

That's a good setup your friend has.
This is pretty easy to use but won't be as good as manual editing.

I've done LPs where you could barely hear the music for the noise and even surprised myself with the end result.

Did everyone notice the "wife acceptance factor"? (He's not married and we give him crap for not even trying to get a girlfriend : he's a really nice guy who is very very funny).

How would everyone else rate this for their setups?

Last year I got hold of some really rare recordings. A group of five of us pitched in and did a group buy on some lps that came up on ebay and I did the transfers. Since they are rare and out of print, I figured these recordings would go far and wide so it would be worth going to some extra effort. I had the records cleaned professionally and then did the transfers on a Technics SL1200 with a Grado cartridge. The cartridge cost me more than the turntable. I also used a Shure pressure gauge to set the stylus weight.

The thing that really lets down the aforementioned setup is the Edirol soundcard. The converters are a quality bottleneck in that system, both at capture and monitoring. I used an RME Fireface. They are not the highest quality converters, but they stand up well against the really nice boutique converters considering the price difference.

Edirol isn't too bad.
It's better than a lot of others.

Its better than a gamer level card but as far as quality audio cards go, it is the bottom of the barrel. A lot of low end soundcards use the same converters, and even when you start looking at gear costing up to $2000 like Digidesign hardware, there are very few standouts because they all use the same off the shelf chips; Sharc, Cirrus, AKM and TI being the most common, all fairly similar, nothing special.

Yeah.....way back when the first PCI cards came out I wanted to make a custom card using Burr Brown converters but couldn't find anyone to make drivers for me.
