VELVOX is a voice plugin that enhances streamers' voices with 2 knobs and zero jargon (Pro features 4 knobs and quick setup).

1. Overview

VELVOX is a voice plugin designed for gaming and chatting streamers. No audio engineering knowledge is needed. By adjusting just 2 knobs with zero jargon, it shapes a streamer's voice into a clear, engaging sound.

• Simple operation with zero technical jargon: Without using any difficult audio terms, you can intuitively enhance your voice with just two knobs: "Fuller voice" (WARMTH) and "Cuts through" (PRESENCE).
• Zero latency: With no processing delay, you never have to worry about your voice falling out of sync with your mouth.
• Lightweight performance: Runs smoothly with minimal CPU usage, so you can stream games comfortably on the same PC.
• Automatic distortion prevention: Output levels are kept in check automatically at the output stage so your sound will not clip no matter how high you turn the knobs.

3. Installation

Installation (Windows)

1. Extract the downloaded ZIP file.
2. Copy the VELVOX.vst3 folder to the following location:
   C:\Program Files\Common Files\VST3\
3. Launch your DAW and perform a plugin rescan (if you copy while the DAW is running, it may not be detected immediately).

Installation (Mac)

1. Extract the downloaded ZIP file.
2. Copy VELVOX.vst3 to ~/Library/Audio/Plug-Ins/VST3/, and copy VELVOX.component to ~/Library/Audio/Plug-Ins/Components/ (where ~ represents your home folder. In Finder, open the "Go" menu, choose "Go to Folder...", paste the path, and press Return. If the folder does not exist, create it).
3. Open Terminal (Applications → Utilities → Terminal), paste the following 3 lines one by one, and press Return for each:

   cd ~/Library/Audio/Plug-Ins
   xattr -dr com.apple.quarantine VST3/"VELVOX.vst3"
   xattr -dr com.apple.quarantine Components/"VELVOX.component"

4. Launch your DAW and perform a plugin rescan (if you copy while the DAW is running, it may not be detected immediately. If AU does not appear in Logic Pro or other DAWs, restart your Mac).

Uninstallation

[Windows] Delete the copied VELVOX.vst3 folder.
[Mac] Delete the copied VELVOX.vst3 and VELVOX.component files.

4. Using with OBS

Because OBS cannot load VST3 plugins directly, install the free OBS plugin "atkAudio Plugin" and run VELVOX inside it. OBS Studio 31.1.1 or later (64bit) is required.

1. Install the installer for your OS from the atkAudio Plugin download page.
2. Launch OBS and open "Filters" for your microphone audio source.
3. Click "+" and add "atkAudio Plugin Host".
4. Click "Open Plugin Settings", and under "Options", select "Scan for new or updated VST3 plugins" to detect installed plugins (first time only).
5. Select VELVOX from the list, click "Load Plugin" to load it, open the window, and turn the knobs.

* In a DAW (such as Ableton Live), simply insert it as a standard effect on your vocal track.

5. The screen

Header bar (top)

• Logo & version: Displays the logo and version at the top left of the window.

InfoBar

• Located right below the header. When you hover over a knob, it explains what that knob improves (displays in English on an English OS, and in Japanese on a Japanese OS; default text: "Hover over a knob to see what it improves.").

VOICE "Shape your voice"

• WARMTH "Fuller voice": Turn up if your voice sounds thin or weak. Adds body and warmth. Automatically keeps the sound clear even if turned up high.
• PRESENCE "Cuts through": Turn up if your voice gets buried under game audio or background music. Automatically softens harsh S sounds so it never hurts the ears. While active, the "Taming S sounds" indicator dot below the knob lights up.

CLEAN "Clean up" and AUTO "Quick setup"

• Features of the Pro edition. While visible on the screen in the free edition, they have a PRO badge and cannot be adjusted.

OUT "Voice level" meter

• If the bar stays within the target zone while you speak, your voice is at an easy-to-hear volume for streaming.
• Output levels are kept in check automatically so your sound will not clip no matter how high you turn the knobs.

6. How to use

1. Turn up PRESENCE while speaking, and stop where your voice cuts through game audio and background music.
2. If your voice sounds thin or weak, turn up WARMTH.
3. Check the OUT meter to see if the bar stays within the target zone while speaking. If it does not reach the zone, adjust the mic input gain (via your computer sound settings or audio interface knob). The volume fader in the OBS mixer is applied after VELVOX, so it does not affect the meter here.

* The default value for each knob is 40.

7. Tips

• If you want to eliminate background noise even while speaking, combine VELVOX with Tonecraft Tokyo's AI noise suppression plugin SILENTIQ (Trial version / Full version) or OBS built-in noise suppression (RNNoise).

8. About VELVOX Pro

For users who need more advanced capabilities, the upgraded edition "VELVOX Pro" is available. VELVOX Pro adds the following features:

• CLEAN panel CONTROL "Evens out level": Tames harsh spikes when shouting and evens out volume variations.
• CLEAN panel NOISE "Removes noise": Silences keyboard, AC, and fan noise while you are not speaking.
• AUTO "Quick setup": Sets up all 4 knobs automatically to fit your voice and microphone just by speaking for 10 seconds.
