Tips & Tricks

Prepare your track for the best results...

Remove Any Master Bus Processing

Remove any plugins you can from your master channel on your song before sending it to eMastered. These plugins will compete with our engine, and give you a worse sounding result.

Leave Headroom

If your track is too loud the mastering engine won't have much to work with. Make sure the file you upload is -3 to -6 dB at its loudest point before sending it to eMastered.

Upload Unmastered File

Make sure the file you upload hasn't already been mastered. If it has the engine won't be able to master it correctly, so always use an unmastered version of your song when uploading it.

1. Leave Headroom
The most important thing to keep in mind is to avoid clipping.
Make sure your master channel is never hitting 0 dB, and ideally aim to have the master channel hitting between -3 and -6 dB.

2. Export Highest Quality Format
Try and export the audio at the highest possible format both in terms of bit depth and sample rate (a good number to aim for is 48 kHz sample rate and 32 bit depth) which will provide eMastered with the highest quality audio from which to work with.

3. Clean Up The Frequencies
Do your best to remove unnecessary frequencies from the individual tracks in a session before bouncing your unmastered file, as removing these frequencies will provide a cleaner product for eMastered to work with and will provide better results.

4. Remove Plugins
If possible, remove any plugins you can from your master channel. These plugins can negatively impact how eMastered will improve your song, so to get the best result we recommend removing plugins on the master bus before sending to eMastered.

"I use eMastered for every song I make. I can’t believe how it can make my track sound radio ready within minutes.
This is a complete game changer for my music production."

Smith Carlson - GRAMMY Award Winner “Taylor Swift's - 1989” (Maroon 5, Kanye West, Beyonce, OneRepublic,
Demi Lovato, Diddy, T.I.)

"eMastered has become an essential element in my music making process.Simple, fast and most importantly, incredible quality. This will become a standard for anyone making music."

- Clinton Sparks - GRAMMY Nominated Producer & Writer (Lady Gaga's "Born This Way")

"I tried eMastered on an instrumental that I did some light mixing on, and the engine did some great EQ'ing and compression. It really enhanced the track."

Tae Beast - GRAMMY Award Winner (Kendrick Lamar "To Pimp A Butterfly")

"I was blown away when I heard eMastered for the first time. It did such an incredible job for a variety of different songs that I threw at it. I wish it had existed when I was starting out."

Carlos "CID" Cid - GRAMMY Award Winner (Lana Del Rey - Summertime Sadness - Cedric Gervais Remix)
