Corduroy Vinyl Production

Since the music world has been producing music mainly for CD for the past fifteen years or so, there are now few mastering engineers who know the 'secrets' of mastering for vinyl. Masters produced for CD are often incompatible with LP masters. We at Corduroy think it's important you know the differences, so you can prepare suitable masters for Vinyl cutting. Please read the following carefully, and if you have any further questions, please phone Nick Phillips on (03) 9553 5063.

Vinyl Discs have limitations on side lengths which vary according to the recording technique used. The longer the sides, the quieter the music has to be cut, but we will always try to make your music as loud as possible. The following table lists the typical dB levels available for the various formats of discs.

TWELVE INCHES

33 rpm dB NOTES 45 rpm dB NOTES

14 mins +4 Loud dance / hip-hop 10 mins +4 Loud dance / hip-hop

18 mins +2 Great length for rock'n'roll 12 mins +4 Great

20 mins +1 Good 14 mins +2 Maximum recommended

22 mins 0 OK 16 mins 0 Suggest 33 rpm

24 mins -1 Maximum recommended

SEVEN INCHES

33 rpm dB NOTES 45 rpm dB NOTES

5 mins +2 Loud single 3 mins +3 Good & loud single

6 mins 0 Normal EP volume 4 mins +1 Good

7 mins -1 Maximum recommended 5 mins 0 Maximum recommended

8 mins -2 Getting quiet 6 mins -1 Suggest 33 rpm

* "7" records over 5 minutes on 33rpm are not recommended as the sound quality is sacrificed. Unless a lo-fi sounding record is what you are after, we recommend you steer clear of this."

Masters are accepted on CD or DAT. Accompanying the master must be a clearly legible TOC or cue sheet showing the Start and Finish times of each track, the Artist and Title, track names, Label and Catalogue Number (if used) and if you like, any inscriptions required on the vinyl runout grooves - limit 10 characters

Unless specifically instructed otherwise, we will cut your master exactly as it is presented. We can of course EQ, limit, compress, re-edit and if necessary burn a pre-mastering CDR or cut a dub plate for your approval, at an extra cost.

There MUST be at least 30 seconds of silence between sides A & B. The written start and finish times must not include this silence. Making a pause command is not enough.

CDR: The best way to do this is to record a 30 sec "silence" track and insert it between sides A& B, so it shows up as "silence" on the TOC and we will know when side A ends.

DAT: Your DAT must show absolute time on the recording, and Start ID's must be offset at least 600 m/s before the start of sides A & B. The program must start at least one minute into the DAT.

Any special instructions (eg fade track 3) must be included with the TOC or cue sheet. All tracks should be level matched and EQ'd to your taste. Unlike CD's, vinyl levels are relative. There's nothing to be gained by squeezing a master though a digital maximiser such as a TC Electronics Finaliser set on 'maximum' to produce a constant digital level of O dB, unless you particularly like that sort of sound.

When a recording is "in phase", the stylus moves nicely from left to right. When it's "out of phase", the stylus moves up and down, causing it to jump out of the groove given half a chance. In the "good old days" of expensive studios, most good consoles had a 'phase correlation meter' on the output. Since phase is irrelevant to CD, this expensive extra is usually unavailable to todays engineers, leading to major headaches when trying to cut vinyl from digitally recorded or mixed masters.

Especially critical is the bottom end - when this is out of phase, the recording can be near impossible to cut. Extremely "subby" dance mixes usually present the biggest problem but are OK if the bass & kick are in phase. It's not such a problem for lo-fi garage recordings, unless the feedback gets REALLY trebly and piercing, which will be removed during cutting anyway. Well-recorded acoustic stuff is no problem at all. Most problems come from live recordings made from the desk, or from stereo samples where a plug-in DSP has removed a solo instrument or leaving the rhythm track. Using Stereo widening Plugins is often disastrous, and may cause the inner tracks to sound dull. Mono samples panned near to the centre don't have the same problem.

How can I tell if my mix is out of phase?
If you don't have a phase correlation meter on your desk or in your hardware, try reversing the phase of one side of your mix and listen to the result in Mono, panning both sides to the centre. If the mix is entirely in phase and the levels match, then the result will be almost silence. Reverbs and flanged/phased sounds won't entirely cancel because they rely on being a bit out of phase to work. As long as the result is mainly high frequency, there won't be a problem. If heaps of bottom end still comes through, there will be a problem and the record may need a remix in order to be cut at all.

Hint: Many mixers invert the phase of the signal from the Aux sends, so you can send one side of the mix from an Aux send, return it to another channel and then mono it as above to check the phasing.

Be sure to bring phasing up with whoever is mixing your next recording and we won't have to spend 6 hours and $200 in acetates waxing those phat beats.

We can accept artwork on disk, hard copies or final film work (even plain paper is fine for one colour jobs). Photoshop/Quark/Illustrator files are all OK on either Mac or PC, but please make sure they're completely ready to output to film.

If you're providing film for us to print the labels, ensure that the film is screened at no more than 60%, or 30% recommended for solid. If you cannot do this, we will arrange the printer to do this for you, but again you will be charged extra for this service. Labels with solid art stick to the pressing plates, often causing damage and necessitating a recut, which costs you time and us money.

Our printers can tackle anything you throw their way. Contact us for details or email Nick a nick@corduroy.com.au

7" -- 92mm diameter
12" -- 102mm diameter

When laying out your label artwork, be sure to allow 3mm of bleed around your artwork, and ensure that the 2 sides are set out at least 10mm apart from cut to cut. For best results it's best not to rule a line around the diameter of the label as sometimes this can be visible on the finished label. The same applies to the hole in the centre of the labels. Please just use a small dot or cross to mark the middle of your artwork.

We can typeset labels for you if you like but a charge of $44 will apply.
