The Most Common Mixing Mistakes and How to Eliminate Them.
2-Hour Online Workshop with Wojtek Wiesławski, engineer and producer.
- Stuck with your mix?
- Does it sound worse the longer you work on it?
- Sounds fine only on your monitoring setup but falls apart elsewhere?
That’s the result of a few fundamental mixing mistakes that nearly every engineer makes. Sign up, and in just three hours you’ll learn how to eliminate the most common mixing mistakes – whether you’re mixing in your bedroom or in a studio.

Join an intensive 2-hour online workshop led by Wojtek Wiesławski — engineer with over 25 years of experience, co-founder of Hertz Recording Studio.
- Over 300 albums produced;
- Double Platinum and two Fryderyk Awards;
- Worked with Behemoth, Decapitated, Patriarkh, Vader, Hate, Hour Of Penance, and many more.
“I learned from my mistakes, and now I’ll show you how you can avoid them!”
What mistakes will you eliminate?
You’ll learn to quickly detect and fix the most common mistakes in your mixes:
- Poor instrument balance;
- Overcompression;
- Overuse of EQ;
- Wrong choice of plugins;
- Lack of clarity;
- Lack of control over the low end.
Who is it for?
- Engineers and producers who want to record better and mix faster;
- Artists who want to capture their own music in top quality;
- Anyone recording audio at home or in the studio.
Why join?
