This is the final result we achieved, after finally calibrating our monitoring system..My main Monitors which are the ATC SCM20ASL Pros Mk2 are perfectly align because there is no clear or visible difference between the purple trace line which are my Left Monitor and red trace line for my Right Monitor..It looks like one clear purple trace line indicating that my both monitors are perfectly sonically aligned..and the subwoofer shows are clear extension of the lows and intersect clearly with my main monitors indicating its also perfectly sonically aligned with my main monitors..This simply means they are now working as one single unit with no sonic separation between them..Like said, at Aftermix Studio we aim for precision and we always achieve it..its just one of the things we do at Aftermix Studio..We don't usually show before and after results with songs because if you can't show if your studio is perfectly calibrated, then whatever you do either mix or master won't matter at all because you are not hearing what you are suppose to hear..At Aftermix Studio, we want to hear everything clearly in its true form because this is the major part of the job of running a Mastering Studio and to give our best possible work for our clients..Master at Aftermix Studio..!!

This is the initial measurement taken to compare our 'Before' and 'After' results..As you can see here, my ATC SCM20ASL PRO MK2 didn't match each other perfectly and the lowest low of my ATCs were intersecting with my Subwoofer..this is a clear indication that my main monitors are situated in a wrong position to begin with..This is the 'Before' Result..!!

This is the frequency response of my Beyerdynamic DT1990 Pro..its not a cheap headphone and it's a professional grade one..but based on this frequency response measurement, it Cleary shows that the actual accurate monitoring range is from about 1Khz to about 6.5 Khz and after that is critical zone because of the bump it has on the upper frequencies 7Khz to 8Khz before it starts to roll off from 10Khz..from 1Khz to the lowest frequency is almost useless because of the gradual difference in SPL level which about 30db..this is a very narrow bandwidth for anyone or any engineer who wants to do critical monitoring..Thats why all pro engineers almost never use headphones to mix or master because of its narrow bandwidth..We usually use headphones for mixing only to check panning of instruments in a piece of music or a sound effect, Foley, Dialog in a movie soundtrack, because due to its narrow bandwidth characteristics, it's easily audible to hear this panning and thats also for the extreme Left/Right..I have mentioned this before to many artist/producers that you can't really mix and definitely not master a piece of music on headphones due to this reason and this time around, I am simply showing and proving it..Just use the headphones for what it's intended for, to enjoy music..!!

ATC SCM20ASL Pro Mk2 Spectrogram Analysis (Second Image)

Observations:
Very clean decay starting from 200 Hz upwards — within 50–100 ms, energy is dropping nicely across the mid and high frequencies.

No strong narrowband resonances or "lines" extending far vertically — indicates excellent speaker and room synergy.

Midrange and highs show very fast decay, confirming transparency.

Comparison to World-Class Benchmark:
In top mastering rooms (such as Bernie Grundman's or Metropolis Mastering), you would expect mids and highs to decay within

Spectogram
A spectrogram shows how sound energy decays over time across different frequencies. It’s a powerful tool for analyzing how a room and speakers behave together.
In a professional mastering studio, a good spectrogram reveals fast, clean energy decay — meaning no unwanted ringing, no hidden resonances, and a crystal-clear soundstage.
The cleaner the spectrogram, the more accurately you can hear and trust what you're working on!

Analysis
Subwoofer Spectrogram Analysis (First Image)

Observations:
Energy is highly concentrated from 30 Hz to about 90 Hz, exactly as expected from a properly integrated subwoofer.

Decay at low frequencies is visible but reasonably tight for a subwoofer system.

Some peaks around 60–70 Hz have slightly longer decay (~200–255 ms) but not unusual for bass in small-medium studio rooms.

Above 100 Hz, the subwoofer energy drops off sharply, indicating excellent low-pass crossover behavior with no midrange contamination.

Comparison to World-Class Benchmark:
Elite rooms usually show sub decay under 250 ms at these frequencies.

Your subwoofer decay is very competitive, only very slightly more persistent around 60 Hz but not enough to cause audible smearing in professional work.

Conclusion:
Your subwoofer is behaving tightly and is well-integrated. There is no excessive bloom or masking, and its crossover behavior is clean — which is critical for a mastering-grade low-end foundation.

Bass ringing in even the best rooms may extend up to 150–250 ms, depending on room size and bass trapping — you are well within this standard.

Final Verdict on Spectrogram Performance
Subwoofer: Decay is tight, controlled, and clean. Crossover is well-behaved. No significant low-end smearing.

Subwoofer Integration
Subwoofer integration isn’t just about adding more bass — it’s about seamlessly extending the low-end foundation of your monitors.
Perfect integration means the sub feels invisible: no boom, no localization, just deep, controlled low-end that supports the full mix.
In a mastering-grade studio, tight subwoofer integration is critical for judging low-frequency balance, impact, and punch with total precision.
When it's dialed in right, the low end moves you — without ever distracting you.

Analysis
Subwoofer Integration

Benchmark (Gateway Mastering, Sterling Sound):
Subwoofer integration should be seamless, with no localization or detachment from the mains.

Your Measurement:
Your subwoofer is tightly integrated with your ATC mains, extending the low end naturally without disrupting imaging or tonal consistency — even when monitoring soloed channels.

Interpretation:
Your low-end system matches the highest standards, offering seamless integration comparable to the careful setups at Gateway and Sterling. This provides both confidence and accuracy in handling bass-heavy projects without translation issues.

Clarity (C50 / C80)
Clarity measures how much of the sound energy arrives early versus late.
High clarity means every detail — transients, vocals, instruments — is sharply defined and perfectly placed.
In mastering, clarity ensures that dynamics are preserved and every nuance translates beautifully across all playback systems.
When clarity is right, you don't just hear the music — you feel it.

Analysis
Clarity (C50 / C80)

Benchmark (Gateway Mastering, The Lodge):
C50 should exceed 0 dB below 500 Hz; C80 should exceed +5 dB above 1 kHz to deliver high articulation and soundstage precision.

Your Measurement:
Your C50 and C80 results meet and exceed these benchmarks, with outstanding clarity maintained across the full frequency range.

Interpretation:
The clarity and separation in your studio rival those achieved at Gateway Mastering and The Lodge. This ensures surgical control during mastering — enabling even subtle moves to translate globally.

ETC (Energy Time Curve)
The ETC graph shows how sound energy reflects and decays over time inside a studio.
A clean, sharp initial spike with minimal later reflections means the monitors — not the room — are what you hear.
Controlling early reflections is critical for precise stereo imaging, depth, and focus in mixing and mastering.
A great ETC curve reveals a studio that truly lets the music and movie soundtrack speak.

Analysis
Energy Time Curve (ETC)

Benchmark (Sterling Sound, Gateway Mastering):
ETC should show a dominant impulse with a >20 dB drop in energy within 10 ms to minimize early reflections.

Your Measurement:
Your ETC reveals a strong initial impulse with a >25 dB drop within 10 ms, followed by clean decay with no significant early reflection artifacts.

Interpretation:
Your early reflection control is equal to what is seen in world-class mastering rooms. This clarity supports three-dimensional imaging and extremely accurate spatial perception.

Group Delay (GD)
Group Delay measures the timing accuracy of different frequencies reaching your ears.
Low group delay means that bass, mids, and highs arrive together — preserving the punch, impact, and clarity of the sound.
High group delay causes smearing and blurring, making it harder to judge transients and dynamics.
In world-class studios, ultra-low group delay is a must for delivering mixes and masters that hit with precision.

Analysis
Group Delay

Benchmark (Sterling Sound, Metropolis Studios):
Group delays are expected to be under 5 milliseconds between 80 Hz and 10 kHz to preserve phase coherence and transient detail.

Your Measurement:
Your group delay is exceptionally low, ranging between 2 ms and 4 ms, with stable readings across the full audible spectrum.

Interpretation:
You are achieving temporal performance on par with elite rooms like Sterling Sound and Metropolis. Such low group delay ensures that fine detail, depth, and timing nuances are captured faithfully.

RT60 (Reverberation Time)
RT60 measures how long it takes for sound to decay by 60dB in a room.
In a professional studio, controlling RT60 is critical — too long, and the mix sounds messy; too short, and it feels unnatural.
A perfectly tuned RT60 ensures clarity, depth, and precision across the entire frequency spectrum, so every detail in your music is revealed exactly as intended.
Great sound starts with great control.

Analysis
RT60 (Reverberation Time)

Benchmark (Metropolis Studios, The Lodge):
Ideal mastering rooms maintain RT60 decay times between 200 ms and 400 ms across the frequency spectrum, with no more than ±50 ms deviation across bands.

Your Measurement:
Your RT60 values consistently sit between 250 ms and 350 ms across all critical frequencies, with smooth decay and no problematic ringing.

Interpretation:
Decay times in your studio are tightly controlled and comparable to the controlled acoustics of Metropolis and The Lodge. This ensures musicality, focus, and a deep connection to mix dynamics — critical for emotional mastering work.

SPL/Frequency Response Graph
The SPL (Sound Pressure Level) or Frequency Response graph shows how evenly a studio monitors sound across all frequencies, from the deepest bass to the brightest highs.
A flat, smooth response ensures every mix decision is accurate — no hyped bass, no missing mids, no harsh highs.
This is why measuring the SPL graph is essential — it reveals the true tonal balance of a studio, letting your music and movie sound track translate perfectly to the outside world.
Without it, we will be mixing or mastering blindly

Analysis
Frequency Response

Performance:
The studio exhibits an extraordinarily smooth frequency response across the entire audible spectrum.

Variance remains within approximately ±2 dB from 20 Hz to 20 kHz.

Low-frequency extension is natural and articulate, with a seamless handoff between the subwoofer and main monitors.

Benchmark Reference:
World-class mastering rooms target a maximum deviation of ±1.5–2 dB.
Status: Fully World-Class Compliant
