Indicates the frequency range that a microphone can capture and is expressed in Hertz (Hz). The more balanced the range, the more natural and clear the sound.

Usage examples:

• 100 – 10,000 Hz to 200 – 12,000 Hz: Emphasis on speech intelligibility, with limited low and very high frequencies.
• 50 – 14,000 Hz to 80 – 16,000 Hz: Balance of volume and clarity. Ideal for live performances and dynamic microphones.
• 40 – 15,000 Hz to 50 – 18,000 Hz: Rich, natural vocal sound. Suitable for podcasts, radio, and streaming.
• 20 – 18,000 Hz to 20 – 20,000 Hz: Full spectrum with high detail and "air". Ideal for studio recording.
• Below 20 Hz & above 20,000 Hz: Extended technical range for specialized studio applications.

Max SPL (Maximum Sound Pressure Level) is the maximum sound pressure level (in dB) that a microphone can withstand before it starts to distort the sound.

• High Max SPL (e.g., 140-160dB): Ideal for recording loud sources such as drums, amplified guitar, or live concerts.
• Lower Max SPL (e.g., 120dB): Suitable for vocals and softer recordings.

The higher the Max SPL, the louder the sounds it can capture without distortion.

Indicates the difference between the useful signal and the microphone's noise. The higher the value in dB, the clearer the sound. A microphone with a low SNR may sound “noisy,” especially in quiet environments or when recording low-volume sounds. On the other hand, a high SNR means that noise is minimal compared to the sound you want to capture, offering a more professional, clear, and detailed result—ideal for studio, vocals, or high-quality recording.

• 35 – 60 dB (Low SNR): Noticeable noise is present. Suitable for casual use or loud sources.
• 60 – 90 dB (Medium SNR): Good signal-to-noise balance. Suitable for live performances and general use.
• 90 – 110 dB (High SNR): Very clear signal with minimal noise. Ideal for studio, vocals, and high-quality recording.
