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

 SORYNO EQ Free  v1.0.2

 3-band parametric EQ (Windows / VST3)

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



Thank you for choosing SORYNO EQ 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.



A straightforward 3-band EQ to set the tonal balance at the

start of a mix.





[ 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 EQ 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 ]

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



  - Three parametric bands (LOW / MID / HIGH).

      Each band has FREQ (frequency), GAIN and Q (width).

  - HPF (high-pass) and LPF (low-pass).

      6 / 12 / 24 / 48 dB/oct.

  - Output gain.

  - Real-time analyzer (input and output drawn together).

  - Drag the nodes on the graph to work by eye.

  - 10 presets.



  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 EQ Pro ADDS ]

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



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

  same way and adds the following.



  - Eight bands (SUB / LOW / LOW-MID / MID / HIGH-MID / HIGH /

    PRESENCE / AIR).

  - SHAPE per band (Bell / Low Shelf / High Shelf / Notch).

  - Mid/Side processing (work on the centre or the sides alone).

  - Dynamic EQ (an EQ that only acts when the level is high; for

    "the low end swells in the chorus" or "one note is piercing").

  - Linear Phase (no phase rotation; for mastering).

  - Auto gain (compare the EQ itself without being fooled by a

    level difference).

  - Advanced analyzer (resolution, speed, peak hold).

  - 112 presets in 11 categories.



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

  See the SORYNO shop on BOOTH.





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

  SORYNO EQ 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

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

  SORYNO EQ Free does not print the version on screen (there is
  not enough room across the title bar). To check which build you
  have, compare the hash below.

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

    6C44C059B59734C73D0BAA40998BE49E78462C082FBE4BC0484751F0EB9E6243

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

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



  The sound arrives late

    -> Check that delay compensation is on in your DAW. This

       plug-in reports its latency correctly.



  The sound changes when I press BYPASS

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

       The sound itself is not altered.
