﻿================================================================

 SORYNO DEESS Free  v1.0.2

 De-esser (Windows / VST3)

================================================================



Thank you for choosing SORYNO DEESS Free.



This is a free version, but it is not a cut-down demo. The aim is

that it is enough to finish the job on its own. There is no time

limit, no restriction on how many times a feature can be used and

no license activation, so it runs offline.



It tames harsh sibilance ('s' and 'sh' sounds) on vocals.





[ SYSTEM REQUIREMENTS ]

----------------------------------------------------------------



  OS              Windows 10 / 11 (64-bit)

  Format          VST3

  Sample rates    44.1 / 48 / 96 / 192 kHz

  Channels        mono / stereo

  Extra runtime   none



  The Visual C++ redistributable is NOT required. Everything the

  plug-in needs is inside the plug-in itself.



  There is no macOS version and no AAX version.





[ HOW TO INSTALL ]

----------------------------------------------------------------



  Double-click  Install.bat



  Administrator rights are NOT required.



  (The other batch file in this folder has a Japanese name and is

  exactly the same thing. Either one will do.)



  It installs to:

    %LOCALAPPDATA%\Programs\Common\VST3



  This is an official VST3 location defined by the VST3 standard.

  The installer also looks in the system-wide VST3 folder and moves

  any older copy of the same plug-in out of the way. It moves it to

  a backup folder; nothing is deleted.



  When it has finished, rescan your plug-ins in your DAW.



  * Prefer to install by hand?

    Copy the folder

      VST3\SORYNO DEESS Free.vst3

    into

      %LOCALAPPDATA%\Programs\Common\VST3

    That is all the installer does.



  * About the Windows warning

    Windows may show "Windows protected your PC". That is because

    we have not bought a code-signing certificate, not because

    there is anything wrong with the file. Choose "More info",

    then "Run anyway".



  * To uninstall

    powershell -ExecutionPolicy Bypass -File install.ps1 -Uninstall





[ WHAT IT DOES ]

----------------------------------------------------------------



  FREQ        2 to 16 kHz     Centre of the band being watched.

  THRESHOLD   -60 to 0 dB     Level above which it starts working.

  RANGE       0 to 24 dB      Most it will ever take away.

  OUTPUT      -24 to +24 dB   Output gain.

  LISTEN      Plays back only the material being removed.



  - Spectrum display.

      The signal before and after processing is drawn together, so

      you can see the band you are aiming at and how much is going.

  - 18 presets, including narration, podcast and cheap-microphone

      settings.



  * How to use LISTEN (this is the quickest way in)



    Press LISTEN and you hear only what is being removed. You want

    to hear the "s" and "sh" sounds and almost none of the words.



    If you hear vowels or low end, raise FREQ.

    If you hear almost nothing, lower THRESHOLD.



    Turn LISTEN off again when you are done.



  Fixed in the free version (adjustable in Pro):

    band width (WIDTH) / wideband processing / ATTACK and RELEASE /

    no look-ahead / MIX 100% / stereo / no automatic threshold.



  These are shown on screen in grey with a gold "PRO" mark, so you

  can see what is fixed rather than having it hidden from you.



  Shared controls:

    A / B       Compare two settings (B>A copies B onto A).

    UNDO/REDO   Step back and forward.

    INIT        Return to the default setting.

    BYPASS      Stop processing.

    Window      Drag a corner to resize.



  * About BYPASS

    Unlike most plug-ins, the latency is still applied while BYPASS

    is on. Switching it does not move the timing of the audio, so

    you can compare against other tracks freely. This is deliberate.





[ WHAT SORYNO DEESS Pro ADDS ]

----------------------------------------------------------------



  If the free version is not enough, consider Pro. It works the

  same way and adds the following.



  - Split-band processing, so the rest of the band is not thinned.

  - Band width (WIDTH).

  - ATTACK, RELEASE and look-ahead.

  - MIX (blend with the dry signal) and automatic threshold.

  - Mid/Side.

  - 36 presets.



  Pro versions are in preparation and are not on sale yet.

  See the SORYNO shop on BOOTH.





[ RELEASE NOTIFICATIONS ]
----------------------------------------------------------------

  SORYNO DEESS Free is free. When a new version is released you can
  download it from the same BOOTH page at any time.

  The plug-in checks for a newer version when its window opens. If one
  exists it shows a notice. It never installs anything by itself.

  * To switch the check off
    Right-click anywhere on the plug-in window and untick
    "Check for updates". It works over knobs and graphs too.

    - The change takes effect the next time you open the plug-in.
    - The setting is saved with your song (the DAW project), not as a
      machine-wide preference.

  * What the check sends
    Nothing.
    It reads one small text file hosted on GitHub. No information
    about you, your computer, your projects or how you use the
    plug-in is ever sent. The version comparison happens on your
    machine. If there is no connection it simply does nothing.

[ WHAT CHANGED IN v1.0.2 ]
----------------------------------------------------------------

  * The sound is bit-identical to v1.0.0 and v1.0.1.
    (Checked by nulling the old build against the new one:
     the difference is exactly zero.)
    What changed is the display and the handling:

  - Right-click now works anywhere on the window, including over
    knobs and graphs (this is where the update-check switch lives)
  - A failed preset save is now reported instead of being silent
  - A damaged preset file is moved aside instead of overwritten
  - The "check for updates" setting is no longer reset by presets
  - The update notice is now a readable card
  - Gain-reduction meters now fall back at the same rate

[ HOW TO CHECK THE VERSION ]
----------------------------------------------------------------

  The version is shown at the top left of the window, to the
  right of the product name.

    V1.0.2

  To check the file itself, compare the hash below.

  SHA256 of
    VST3\SORYNO DEESS Free.vst3\Contents\x86_64-win\SORYNO DEESS Free.vst3

    719BCDACA65BE9EFE7628537D8E97BDCDE353DB4ED78970A02660C55D7A9F226

  To check it, paste this into PowerShell from this folder:

    Get-FileHash "VST3\SORYNO DEESS Free.vst3\Contents\x86_64-win\SORYNO DEESS Free.vst3"


[ IF SOMETHING GOES WRONG ]

----------------------------------------------------------------



  It does not appear in my DAW

    -> Rescan your plug-ins. If it still does not appear, check

       whether an older copy is left somewhere else.



  I cannot tell whether it is working

    -> Press LISTEN. You will hear only what is being removed. If

       you hear nothing, lower THRESHOLD.



  The sound is dull or thin

    -> The free version turns the whole band down (wideband). Try a

       smaller RANGE, or a higher FREQ. If you want to process a

       narrow band only, consider Split-band in Pro.



  The sound changes when I press BYPASS

    -> Latency is still applied while BYPASS is on (by design).

       The sound itself is not altered.
