EQVita is a system-wide graphic equalizer kernel plugin and companion app for PS Vita and PSTV that processes all console audio in real time.

EQVita adds a configurable multi-band equalizer that affects every title, including games, homebrew and system apps, which makes it useful for tailoring the console’s sound to different headphones, speakers or recording setups.

Install

1. Copy eq_speaker.skprx to ur0:tai/.

2. Add to ur0:tai/config.txt under *KERNEL:

   *KERNEL
   ur0:tai/eq_speaker.skprx

3. Reboot.

4. Install EQVita.vpk.

5. Run EQVita to adjust settings.

Note: The plugin is disabled by default to prevent boot issues. Launch EQVita to enable it.

Usage

• Bands: 31Hz - 4kHz (Note: HPF option disables frequencies under 70Hz).
• Gain: ±12 dB
• Controls:
  • Triangle: Save preset
  • Square: Load preset (ux0:data/eqvita/preset0.bin)
• Status: Shows route, sample rate, and clip count.

Notes

• Hardware: Tested on PS Vita 1000 (PCH-1000) with Switch OLED speaker mod. Should work on other models.
• Personal Config: I use +4 on bass and -4 on midrange. The difference is quite big.
• Disclaimer: This is my first PS Vita project and a hobby endeavor. If it works, it works.
• Credits: UI images adapted from VitaShell.
• Bluetooth detection is not yet implemented.
• DSP uses an in-place biquad chain with smoothing.
• If audio crackles, reduce gain or preamp.
