Mixing for Vinyl and Streaming at the Same Time: One Master or Two?

One mix, and usually two delivery files: that is the honest answer for an indie record going to vinyl and streaming at once. The mix itself should be the same for both, built so that it cuts cleanly, with the low end in the centre, sibilance under control and real headroom. The master then forks: a streaming master aimed at about minus 14 LUFS with true peaks under minus 1 dB, and a vinyl pre-master that the cutting engineer can work from, which is often quieter, sometimes slightly darker, and sequenced to side lengths. You rarely need two different mixes. You do need to decide before mixing that vinyl is happening, because four of the decisions below are mixing decisions, not mastering ones.

What vinyl physically cannot do

A record groove is a mechanical copy of the waveform, and it has limits that a file does not. Very low frequencies that differ between the left and right channels make the groove move vertically, which can cause the needle to skip; loud high frequencies, especially vocal sibilance and bright cymbals, make the cutting head work harder than the groove can hold, and distort. Level and playing time trade off: the louder a side is cut, the wider the grooves, the less music fits. Gotta Groove Records, a pressing plant, publishes the practical numbers: a 12-inch side at 33 rpm is ideal up to about 18 minutes and possible up to about 22 with compromises, a 12-inch at 45 rpm is ideal up to 12 minutes, a 7-inch at 45 rpm up to about four and a half minutes, and bright or heavy material shortens all of those. The plant also asks that the mastering engineer talk to the cutting engineer before work begins, not after test pressings.

What streaming physically does

Streaming platforms turn every track to a reference loudness before playback. Spotify plays at about minus 14 LUFS by default (minus 11 on its Loud setting, minus 19 on Quiet), applies a limiter to quiet tracks that get turned up, asks for true peaks under minus 1 dB and under minus 2 dB if the master is louder than minus 14 LUFS, and wants one stereo master per track. Apple Music's Sound Check works to a similar reference around minus 16 LUFS. The consequence is that a master crushed to be loud gains nothing on streaming and loses impact. Vinyl, which has no normalisation, rewards the same thing for a different reason: a master with headroom and real dynamics cuts louder and cleaner than a limited one, because the limiter's flat tops are what the cutting head dislikes.

The four mixing decisions that serve both

Put the low end in the middle. Kick, bass and anything below about 120 Hz should be mono or close to it; wide sub-bass is a vinyl problem and does nothing on a phone speaker either. We check every mix in mono and listen for the bass disappearing or doubling. Control sibilance in the mix, not only in mastering: a de-esser on the lead vocal, and on bright hi-hats and tambourines where they are harsh, so the cutting engineer is not fighting a problem the mix could have solved. Keep headroom and leave the bus limiter off: peaks around minus 3 to minus 6 dBFS, no brickwall on the mix, so mastering sets the final level once for streaming and once for the cut. Keep the mix's phase honest: wide stereo tricks from phase trickery, pseudo-stereo plug-ins and hard-panned low-frequency sources all cause trouble on a lathe and collapse in mono. None of these four makes the record sound smaller. They make it cut.

Sequencing is a mixing-stage conversation

Side lengths change the running order, and the running order changes what a mix has to do. The loudest, brightest and heaviest songs cut best at the start of a side, where the groove speed is highest; quieter and darker songs tolerate the inner grooves better. If the album's emotional sequence puts the biggest song last, the band and the mastering engineer need to agree whether to accept a slightly quieter cut, move the song, or split the record across more sides. That conversation belongs in the mixing stage, because a song that will end a side may want a mix with slightly less top end and a tighter low end than it would get as a stand-alone single. Tell your mixer the intended sides before the first mix.

When you really need two masters

Always two deliverables; rarely two different-sounding masters. The streaming master is the final, level-set stereo file. The vinyl pre-master is usually the same balance at a lower level, without the final limiting, sometimes with a touch of high-frequency control and a mono check below about 100 Hz, delivered with the side sequence and the gaps, so the cutting engineer can apply what the lathe needs. A different-sounding vinyl master is justified when the record is very dense and bright, when a side is long, or when the band wants a deliberately different vinyl character; in each case it should be a decision made by listening, not a rule. What you should not do is send the loud streaming master to the plant and hope. Spotify's one-master rule is for Spotify; the plant needs its own file.

What this means for a Tapetown mix

When a band tells us vinyl is planned, we mix with the sides in front of us, keep the low end centred and the headroom intact, and deliver the mix with a note on the sequence and the gaps. If we also master, you get a streaming master and a vinyl pre-master, with the cutting engineer's requirements agreed before we send anything. If the label has its own mastering engineer, we send them the mixes with the same note and talk to them directly if they want.

What it costs

Professional mixing in Europe is commonly quoted at roughly 400 to 1,200 euro per song, with mastering on top, and a vinyl pre-master is normally a small addition to a mastering quote rather than a second mastering job. Tapetown quotes per project after hearing the rough mix, because scope, song count and the formats change the price. Tell us the formats when you write through the contact page and the quote includes them.

FAQ

Do I need a different mix for vinyl?

Almost never. You need a mix that cuts well, with the low end in mono, sibilance controlled and headroom kept, and then two delivery files from mastering: a streaming master and a vinyl pre-master.

What loudness should a streaming master be?

Spotify plays at about minus 14 LUFS by default and asks for true peaks under minus 1 dB, or under minus 2 dB if the master is louder than minus 14 LUFS. Apple Music's Sound Check works around minus 16 LUFS. A master around minus 12 to minus 14 LUFS with real dynamics is a safe target for indie records.

How long can a side of vinyl be?

About 18 minutes is the comfortable limit for a 12-inch at 33 rpm, up to 22 with compromises; 12 minutes for a 12-inch at 45 rpm; about four and a half minutes for a 7-inch at 45. Bright, heavy or bass-heavy music shortens those figures.

Should the mixing engineer talk to the cutting engineer?

Yes, or the mastering engineer should, before the cut. Pressing plants ask for exactly this, because a conversation about sibilance, low-end width and side lengths before work starts avoids a round of test pressings later.
