Mixing in an Untreated Room

Most bedroom studios have zero acoustic treatment. The room lies to you — bass builds up in corners, reflections smear the stereo image, and frequencies cancel out. Here is how to fight back without spending thousands.

Get Your Mix Roasted

Step-by-Step Guide

Position Your Desk and Speakers Correctly

Place your desk along the shorter wall, away from corners. Form an equilateral triangle between your speakers and head. Pull speakers at least 30 cm from the wall behind them.

Tame First Reflections with DIY Absorption

Hang thick blankets, towels, or rockwool panels at the mirror points — the spots on side walls where sound bounces from the speaker to your ears. Even a bookshelf full of books helps.

Use a Reference Track as Your Calibration Tool

Play a commercial track in your room and learn what it sounds like in your space. If the reference sounds boomy, your room adds bass — compensate accordingly in your mix.

Cross-Reference on Headphones

Make major decisions on speakers, then immediately verify on headphones. Headphones bypass the room entirely and reveal what your speakers cannot show you.

Use Spectrum Analysis to Verify Bass Decisions

Room modes wreak havoc on bass perception. Run a spectrum analyzer on your mix and compare it to your reference. If your ears say the bass is fine but the analyzer disagrees, trust the analyzer.

Avoid Mixing at High Volumes

Loud volumes excite room resonances more. Mix at conversational level (around 75-80 dB SPL). The room lies less at lower volumes.

Pro Tips

Run a free room measurement tool like REW (Room EQ Wizard) to identify your worst room modes. You cannot fix what you cannot see.
Bass traps in corners give you the most improvement per dollar. Even cheap foam bass traps are better than nothing.
Sonarworks SoundID can digitally compensate for your room and speaker coloration — not a replacement for treatment but a powerful supplement.
If your room has flutter echo (a metallic ringing when you clap), hang anything absorptive on the parallel walls causing it.

Common Mistakes

Placing Speakers in Corners

Corners amplify bass massively. You will hear 10-15 dB more low end than is actually in your mix, leading to thin, bass-light mixes.

Covering Every Surface with Foam

Thin foam only absorbs highs, making the room sound dark and unnatural. You need thick absorption (4 inches or more) to treat bass and mids effectively.

Trusting the Room for Low-End Decisions

In most untreated rooms, certain bass frequencies are 10-20 dB louder or quieter depending on your listening position. Always verify bass on headphones or secondary systems.

Frequently Asked Questions

Thick blankets or duvets at first reflection points and in corners. A bookshelf behind your speakers. Rugs on hard floors. These cost almost nothing and make a real difference.

Room correction software helps but cannot fix time-domain problems like reverb and comb filtering. Use it as a supplement to physical treatment, not a replacement.

Sit at about 38% of the room length from the front wall. Avoid the exact center of the room — that is where the worst bass nulls and buildups occur.
