Stem Mastering & Mixing:

Space16 | Online Stem Mastering

Online Stem Mastering is perfect for those tracks that need a little more control in the mastering process

Stem Mastering is different to normal 2 track mastering, instead of sending us a single file you send us up to 8 Tracks (Mono or Stereo) of grouped instruments to use for mastering e.g. Bass, Kick, Other Drums, Lead 1, Lead 2,  Vocals, FX (Sweeps etc).. Stem mastering is also different to our Full Mixing Service which we work with unprocessed parts and effects separately.

This means our mastering engineer has more control over the master of the record and specific parts of the track that may need attention. Please do note that Stem Mastering is not the same as Mixing, as mixing balances all separate instruments individually along with reverbs, delays and processing etc so we don’t do things such as major volume automation (although we may do some slight bits if required) but we don’t add effects, or tune vocals etc.

It’s certainly worth considering stem mastering if you feel your music lacks real punch, width or clarity as it gives us more control to get things as you want them.

We always use high quality analogue equipment for stem mastering such as Manley, Summit Audio, Culture Vulture, Maselec , PMC & Genelec Monitors as well as hand picked plugins that we have tried and tested extensively.

Stem Mastering is called many different things including stem sub mixes and separation mastering

  • Differences between stem mixing & stem mastering,
  • Stem mixing is a method of mixing audio material based on creating groups of audio tracks and processing them separately prior to combining them into a final master mix. Stems are also sometimes referred to as submixes, subgroups, or busses.
  • Stem mastering is a technique derived from stem mixing. Just like in stem-mixing, the individual audio tracks are grouped together to allow for independent control and signal processing of each stem and can be manipulated independently from each other.
  • We offer stem mastering at
  • £45 / €50 / $70  per track
  • (Upto 8 Mono or Stereo tracks)

What you need to do is bounce down each instrument or group of instruments from the same start and end position so when we import them they all start and finish where they should. Also your instrument stems should sound as close as possible to your original project when they are put back together or recombined. If you are using a limiter on your master and it’s part of your sound we recommend you also send us an original version with your limiter on so we can hear how its affecting it.

We like communication between ourselves and our clients, therefore we really appreciate notes about what you like and what you think can be improved about your mix e.g. Synths don’t sound wide enough. The bass is muddy with the kick. I like the way the snare sounds and the lead synths cut through the mix. Just so we don’t take away what you like as well as improving those you don’t like.

After having my masters done at a couple of other places and not being to impressed. I sent my tracks off to Space16 and Sam came back to me within the hour suggesting their stem mastering service and asking for some extra information.\r\n\r\nI had it back that night and wow, it just made such a difference!! I always thought stem mastering was a bit over indulgent but it\\\'s made a huge difference!!! \r\n\r\nI would recommend Space16 to anyone thinking of stem mastering or mastering... You have a repeat customer for sure!”\r\n
