Turn the computer volume down to zeroകമ്പ്യൂട്ടർ വോളിയം പൂജ്യത്തിലേക്ക് കുറയ്ക്കുക

Correct Answer: Option A

Explanation:

Noise Reduction requires an initial 'Noise Profile' sample of pure background noise, after which Audacity filters out matching frequencies across the recording.

ശബ്‌ദം കുറയ്ക്കുന്നതിന് ശുദ്ധമായ പശ്ചാത്തല ശബ്‌ദത്തിൻ്റെ പ്രാരംഭ 'നോയ്‌സ് പ്രൊഫൈൽ' സാമ്പിൾ ആവശ്യമാണ്, അതിനുശേഷം ഓഡാസിറ്റി റെക്കോർഡിംഗിലുടനീളം പൊരുത്തപ്പെടുന്ന ഫ്രീക്വൻസികൾ ഫിൽട്ടർ ചെയ്യുന്നു.

Applying the Distortion filter to the musicസംഗീതത്തിൽ ഡിസ്റ്റോർഷൻ ഫിൽട്ടർ പ്രയോഗിക്കുന്നു

Correct Answer: Option B

Explanation:

Using the Envelope tool (or auto-ducking) lowers background music while speech occurs, maintaining clear voice intelligibility.

എൻവലപ്പ് ടൂൾ ഉപയോഗിക്കുന്നത് (അല്ലെങ്കിൽ സ്വയമേവയുള്ള ഡക്കിംഗ്) സംഭാഷണം നടക്കുമ്പോൾ പശ്ചാത്തല സംഗീതം കുറയ്ക്കുന്നു, വ്യക്തമായ വോയ്‌സ് ഇൻ്റലിജിബിലിറ്റി നിലനിർത്തുന്നു.

How Chapter-Wise Online CBT Tests Build Winning Habits for Future Competitive Exams

Early practice in middle school builds the mental muscle, speed, and analytical discipline required to ace NTSE, Olympiads, JNVST, Sainik School, and Future Competitive Exams.

Competitive Edge

Real-Time Clock Awareness & Pacing

समय प्रबंधन एवं गति नियंत्रण

In school examinations, students write answers without active pacing. In national entrance tests, students have barely 45-60 seconds per MCQ. Practicing with a 20-minute timer instills instinctive time-budgeting and prevents last-minute exam panic.

Mastery of the Elimination Technique

विकल्प निष्कासन विधि में दक्षता

Top rankers in competitive exams rarely compute every problem blindly. They spot subtle traps, evaluate extreme values, and eliminate 2 out of 4 distractors within seconds. Our 4-option sets teach critical distractor analysis.

CBT Screen Stamina & Digital Comfort

कंप्यूटर आधारित परीक्षा का सहज अभ्यास

Almost all major national exams (CUET, JEE, NEET, SSC, Banking) are 100% computer-based. Students who only study on paper experience eye strain and navigation mistakes on exam day. Early CBT practice creates effortless digital fluency.

Immunity to Negative Marking

सटीकता और नकारात्मक अंकन से सुरक्षा

Careless errors—such as misreading "NOT" or "EXCEPT"—ruin thousands of competitive aspirations each year. Regular objective testing builds the habit of double-checking question keywords before locking answers.

Instant Diagnostic Feedback Loop

तत्काल त्रुटि निवारण एवं आत्म-मूल्यांकन
