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

 SORYNO LIMIT Free  v1.0.2

 Limiter with loudness metering (Windows / VST3)

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



Thank you for choosing SORYNO LIMIT 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.



The last stage before you export. It raises the loudness and

keeps the output under the ceiling you set.





[ 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 LIMIT 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 ]

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



  GAIN        -12 to +24 dB   How hard you push in. More = louder.

  CEILING     -12 to 0 dB     Output ceiling. Output stays under it.

  RELEASE     1 to 1000 ms    How fast it lets go.

  LOOKAHEAD   0 to 20 ms      Longer is smoother but adds latency.

  AUTO        Adapts the release time to the material.



  - Waveform display.

      Input, output and the ceiling are drawn together, so you can

      see where and how much was held back.

  - Loudness metering.

      INTEGRATED / MOMENTARY / SHORT-TERM / RANGE / MAX dBTP.

      The difference from the target is shown in plain words, for

      example "+1.5 LU too loud".

  - 14 presets.



  Fixed in the free version (adjustable in Pro):

    no true-peak limiting / standard character / no dither /

    stereo link 100% / MIX 100% / target fixed at -14 LUFS.



  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 LIMIT Pro ADDS ]

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



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

  same way and adds the following.



  * TRUE PEAK (the biggest difference)



    Turned on, it also holds back peaks that sit *between* two

    samples.



    When a streamed or downloaded file is played, the waveform is

    reconstructed smoothly between the recorded points, and the

    curve between two points can rise above both of them. That is

    an inter-sample (true) peak, and it makes the playback device

    distort.



    Turn it on when you deliver to a streaming service.

    The free version does not do this processing, although it does

    show you the MAX dBTP reading.



    OVERSAMPLING lets you choose the accuracy (4x is the value the

    standard specifies, and is the default).



  * Also in Pro

    - Four characters (Transparent / Punch / Smooth / Clip).

    - DITHER and NOISE SHAPING for 16-bit and 24-bit delivery.

    - LINK (how much the two channels move together).

    - MIX (blend with the dry signal).

    - TARGET (set your own loudness target).

    - 24 presets.



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

  See the SORYNO shop on BOOTH.





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

  SORYNO LIMIT 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 LIMIT Free.vst3\Contents\x86_64-win\SORYNO LIMIT Free.vst3

    2244D0B601EFC048D17F91DBED0CE83ACB9199FA6479249ECFD7A42BFFD50BD5

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

    Get-FileHash "VST3\SORYNO LIMIT Free.vst3\Contents\x86_64-win\SORYNO LIMIT 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. Using LOOKAHEAD adds

       latency equal to the amount you set.



  MAX dBTP reads higher than CEILING

    -> The free version does not do true-peak limiting (that is a

       Pro feature). Sample values stay under CEILING, but peaks

       between samples are not held back. Use TRUE PEAK in Pro when

       you deliver to a streaming service.



  The sound changes when I press BYPASS

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

       The sound itself is not altered.
