Description
2S EQ by 2nd Sense Audio is a seven-band fully parametric equalizer with adjustable-slope high-pass and low-pass filters. Each band offers gain control from -60 dB to +15 dB, giving you an unusually deep cut range that excels at removing problem frequencies with surgical precision.
The asymmetric gain range is a standout design choice. While most parametric EQs offer symmetrical boost and cut, the extra 45 dB of attenuation lets you create extremely narrow notch filters to eliminate resonances, harsh sibilance, or room modes without affecting surrounding frequencies.
A built-in real-time spectrum analyzer provides visual feedback of your signal's frequency content as you work. The high-pass and low-pass filters support slopes from 1st to 8th order (6 dB/oct to 48 dB/oct), making the gentle 6 dB/oct option especially useful for transparent roll-offs on mix buses and masters.
Users consistently praise 2S EQ for its clean, transparent sound character and surgical cutting ability. The Q values go as narrow as 0.01, allowing you to isolate and remove specific problem frequencies with pinpoint accuracy.
2S EQ supports 32-bit and 64-bit VST, AU, and AAX formats on Windows 7+ and macOS 10.7+. The download is a compact 10.2 MB installer that requires no iLok or additional authorization.

Tips
- Use the real-time spectrum analyzer to identify problematic frequencies and make precise adjustments.
- Experiment with different filter types to achieve the desired tonal balance.
- Apply subtle EQ adjustments to enhance the clarity and presence of individual instruments.
- Use high-pass and low-pass filters to remove unwanted low and high frequencies, respectively.
Frequently Asked Questions
Does 2S EQ have a spectrum analyzer?
Yes, 2S EQ includes a built-in real-time spectrum analyzer that displays the frequency content of your audio signal. Some users have reported that the analyzer display can have minor graphical glitches when reopening the plugin window, though the audio processing remains unaffected.
How does the -60 dB cut range compare to typical EQ plugins?
Most parametric EQs offer symmetrical gain ranges like +/-12 dB or +/-24 dB. The -60 dB floor on 2S EQ is significantly deeper, which means you can create extremely aggressive notch cuts to completely remove problematic frequencies. This makes it particularly effective for surgical mixing tasks like eliminating room resonances or sharp sibilance.
What filter slope options are available on the high-pass and low-pass filters?
The HP and LP filters support slopes from 1st order (6 dB/oct) through 8th order (48 dB/oct). The gentler 6 dB/oct slopes are useful for transparent roll-offs on mix buses, while the steeper options provide more aggressive filtering for individual tracks.
Is 2S EQ suitable for mastering?
Yes, its clean transparent sound and deep cut range make it well-suited for mastering applications. Audio engineers have included it in recommended lists for mastering EQ chains, noting its surgical precision and the ability to make very subtle adjustments without coloring the signal.
