Preparing Your Project for Mastering

You’ve done it. You finished mixing your new project and gotten past a point that many artists have trouble getting to. We are happy that you’ve made the decision to get it professionally mastered and chosen our Mastering Service to do it. Below are the last steps before sending them to us for mastering.

Make sure its ready

Be sure your song’s composition and the level of the individual instruments are the way you want them. If you are not sure about your mix, we offer a free Mix Analysis with every paid project. If you want more help, we suggest you look at our Stem Mastering service, which gives us great flexibility with this. Don’t worry about matching the volume of commercial releases, we’ll take care of that.

Leave headroom

Your final bounce should have between 8 and 12 dB of peak headroom. Another way of saying this is make sure the peak meters on your master channel are hitting between -12 dBFS & -8 dBFS. If your songs does not, pull down each channel fader a few dB (by the same amount) until your song falls into in that range.

Bypass buss processors

If you have any buss processors such as compressors or limiters on your mix buss, disable them. If a compressor or limiter is vital to the sound of your track, do a separate bounce with it enabled and label that bounce as a reference track so we can match the vibe.

Keep your settings

To achieve the cleanest audio possible, avoid any sample rate conversion or bit depth quantization when mixing down your songs. Keep the same sample rate and bit depth as your song’s project file. For example if your DAW is set to a 88.2 kHz sample rate and a bit depth of 32-bit float for a particular song, bounce it at that setting.

Don’t dither

Noise Shaping & dithering technologies mask the distortion caused by quantizing from higher to lower bit depths by introducing small amounts noise. Since this process adds noise, it should only be done once per song and at the end of the mastering process. Finding most appropriate variation of noise shaping for the particular song is part of our mastering process.

Don’t normalize

Remember that we request between 8 and 12 dB of peak headroom? Enabling normalize would lose this headroom.

Check it on headphones

If at all possible, listen to the final mix of your song (the one you are about to submit for mastering) on a pair of decent headphones and make sure there are no pops or clicks that are not supposed to be there. If there are, figure out what is causing the sound and fix it. Some of the causes of those unwanted sounds are:

  • Clipped audio – check for any of your clipping indicators in your DAW (have you left enough headroom?)
  • Recorded chair creaks or foot taps – can you do an edit or re-record the part?
  • Slow processor or disk – if your DAW has a freeze function, enable it or increase your DAW’s buffer sizes (or do both)

If there are unwanted sounds that you are unable to remove take note of the time they appear in the song and let us know in the project notes. We will see if we can fix it for you.

Organize it

If you are sending us more than one song, please organize your project before sending it to us. Create a folder and name it after the overall project. Then create folders inside it for every individual song naming them after each song. You can include any reference versions in the folder for the song.

Zip it

Once you have your project organized neatly into folders, create an ZIP file of the whole project folder. If you prefer RARs, go ahead and use that. We are not as concerned here with reducing the file size, but compressing your project creates an easy check to make sure none of the data was corrupted during the transfer to our studio.

Once you’ve done all these steps, you’re ready to go. Drop by our order page and we’ll get started on your mastering.
