How to Know the Master is Good

1) Speakers and Room Acoustics, you can Not Tweak What You Do Not Hear 

• Phase Response

2) Avoid Ear Fatigue

• Listen from Outside the Room and in All Possible Options

3) Search for Another Person that is also Trained for Optimal Quality

4) Use Meters Analysis with Caution

• Check Loudness, i.e. Integrated etc.

• Use Loudness Penalty, i.e. Look at How Much the Track will be Lowered by the Streaming Services (or Increased)

5) EQ Balance, i.e. Amount of Lows / Mids / Highs

• Make the Lowest Lows so they Dance Around -24dBFS

• Make the Mids from 100Hz to 2000kHz so they Dance Around -36dBFS to -48dBFS

• Make the Highest Highs so they Dance Around -48dBFS

6) Check for Bad Distortion or Add Distortion

• when you Add Distortion, you can Phase Swap Original vs Master to Hear Distortion (or Others)
