Tonecraft Tokyo — VST3 / AU Plugin

SILENTIQ

User Manual — v1.7

Get the full version — Tonecraft Tokyo ↗

SILENTIQ is an AI noise-suppression plugin (VST3 / AU).
It removes noise from voice tracks of all kinds — home-recorded vocals, podcasts, narration and singing — in real time, using only the CPU.

What's new in v1.7: A new screen. Pick the MODE on the left and compare the spectrum before (grey) and after (cyan) processing on the right. The screen now also comes in English (when the OS display language is not Japanese, the screen is shown in English). Hover over a control to see what it does in the bar at the top.

What's new in v1.6: Fixed a small timing offset in DAW latency compensation (PDC). Timing now lines up at sample rates other than 48 kHz (such as 44.1 kHz) and when switching BYPASS.

About the trial (SILENTIQ Trial)
In the trial, white noise is mixed into the output for about 0.5 seconds every 30 seconds.
The full version has no such limit. See the Tonecraft Tokyo website for the full version.

1. Quick start

  1. Insert SILENTIQ on the track you want to clean up.
  2. Choose a MODE for the material (NARRATION for speech, VOCAL for singing).
  3. Play the audio.
  4. Check that BYPASS at the top right is off (while it is lit, you hear the original).
  5. Set the amount of noise removal with STRENGTH.
  6. If the voice sounds unnatural, raise VOICE PROTECT.

3. Controls in detail

MODE (model)

Switches the noise-removal model to suit the material.

ModeUseCharacter
NARRATION
(default)		 Speech of all kinds
narration / podcasts / streams / meetings		 Removes noise from speech strongly.
VOCAL Singing A model suited to singing. It is gentle on held notes, vibrato and overtones, and keeps the song natural while reducing noise.

STRENGTH (amount of noise removal)

Sets how strongly the selected model suppresses noise.

VOICE PROTECT

Sets how strongly the voice is protected.

BYPASS

4. Suggested settings

Narration / podcasts (standard)

MODE:          NARRATION
STRENGTH:      75%
VOICE PROTECT: 85%

Noisy rooms (air conditioner, extractor fan, etc.)

MODE:          NARRATION
STRENGTH:      90%
VOICE PROTECT: 80%

White noise (a steady hiss)

MODE:          NARRATION
STRENGTH:      20–40%
VOICE PROTECT: 85%

Light hiss only

MODE:          NARRATION
STRENGTH:      50%
VOICE PROTECT: 90%

Singing (home-recorded vocals)

MODE:          VOCAL
STRENGTH:      75%
VOICE PROTECT: 85%

Pushing noise removal too hard can make the voice sound muffled or metallic.
Watch the difference between before (grey) and after (cyan) on the spectrum display, and keep STRENGTH as low as does the job.

5. Latency

SILENTIQ adds a fixed latency for processing.
DAWs with latency compensation (PDC) correct it automatically.

MODELatency (samples)Latency (time @48kHz)
NARRATION1920 samplesabout 40 ms
VOCAL2880 samplesabout 60 ms

The latency depends on the MODE. When you switch, the DAW's latency compensation (PDC) follows automatically. At sample rates other than 48 kHz the time is almost the same and is compensated automatically.

For real-time monitoring (hearing yourself while recording), this latency may be noticeable.
In that case, we recommend using SILENTIQ after recording, as a post-processing step.

6. Requirements

ItemDetails
OSWindows 10 / 11 x64
macOS 11 or later (Apple Silicon / Intel)
FormatWindows: VST3 / Mac: VST3, AU
DAWDAWs that support VST3 / AU (Cubase, Studio One, Ableton Live, Reaper, Logic Pro, etc.)
Sample rate44.1 kHz / 48 kHz (other rates are resampled internally)
CPUWindows: x86_64 / Mac: Apple Silicon, Intel (no GPU needed)

7. Installing and uninstalling

Installing (Windows)

  1. Extract the ZIP.
  2. Copy the SILENTIQ.vst3 folder to: 
    C:\Program Files\Common Files\VST3\
  3. Rescan VST3 plugins in your DAW.

Installing (Mac)

  1. Extract the ZIP.
  2. Copy SILENTIQ.vst3 and SILENTIQ.component to their locations (~ is your home folder. In Finder, open "Go" → "Go to Folder", paste the path, and open it. Create the folder if it does not exist). 
    SILENTIQ.vst3      → ~/Library/Audio/Plug-Ins/VST3/
SILENTIQ.component → ~/Library/Audio/Plug-Ins/Components/
  3. Open Terminal (Applications → Utilities → Terminal), paste the following three lines one by one, and press Return. 
    cd ~/Library/Audio/Plug-Ins
xattr -dr com.apple.quarantine "VST3/SILENTIQ.vst3"
xattr -dr com.apple.quarantine "Components/SILENTIQ.component"
    If nothing is displayed, it succeeded. For the trial, read SILENTIQ as SILENTIQ Trial.
  4. Rescan plugins in your DAW (if the AU does not appear in Logic Pro, restart your Mac).

Without step 3, macOS shows "is damaged and cannot be opened" or "cannot verify the developer", and your DAW will not load the plugin. The command only removes the mark macOS adds to downloaded files. Run it again when you reinstall for an update.

Uninstalling

On Windows, delete the following folder.

C:\Program Files\Common Files\VST3\SILENTIQ.vst3

On Mac, delete the SILENTIQ.vst3 and SILENTIQ.component you copied.

Upgrading from the trial

  1. Delete the trial. 
    Windows: C:\Program Files\Common Files\VST3\SILENTIQ Trial.vst3
Mac:     ~/Library/Audio/Plug-Ins/VST3/SILENTIQ Trial.vst3
         ~/Library/Audio/Plug-Ins/Components/SILENTIQ Trial.component
  2. Install the full version (steps above).
  3. Rescan plugins in your DAW.
  4. In your DAW projects, replace SILENTIQ Trial with SILENTIQ.
