Overview

What Is PitchProof-x64.dll?

PitchProof-x64.dll is a 64-bit audio effect plugin module used by PitchProof, a real-time pitch-shifting and harmonizing effect commonly distributed as a VST plugin for digital audio workstations (DAWs). This DLL contains the DSP (digital signal processing) routines, harmonizer logic, and runtime components that allow a host application to load and run the PitchProof effect.

PitchProof is often used in music production for harmonies, doubling, creative vocal FX, guitar pitch manipulation, and real-time pitch-based processing.

What This DLL Does

PitchProof-x64.dll provides the internal processing engine for the PitchProof plugin, including:

  • Real-time pitch-shifting algorithms
  • Harmonizer and doubling effects
  • Mix/Blend control (dry/wet)
  • Tone and interval shifting
  • DSP initialization and parameter handling inside the host DAW

This DLL is a plugin module, not a standalone application. It must be loaded by a compatible VST-capable host.

Where PitchProof-x64.dll Is Found

PitchProof is normally installed into your DAW's VST plugin directory. Common locations include:

C:/Program Files/VSTPlugins/
C:/Program Files/Common Files/VST2/
C:/Program Files/Common Files/VST3/

Or a custom VST folder defined in your DAW settings.

The DLL should remain in your plugin folder so the DAW can scan and load it at startup.

Why Applications Need This DLL

Your DAW loads PitchProof-x64.dll when you:

  • Insert PitchProof as an audio effect
  • Open a project that already uses the plugin
  • Browse or scan your VST folders

Without this DLL, the PitchProof effect cannot run.

Common Errors Related to PitchProof-x64.dll

PitchProof-x64.dll was not found.

The plugin cannot be loaded.

Failed to scan PitchProof-x64.dll.

The program can't start because PitchProof-x64.dll is missing.

These errors typically occur when:

  • The plugin file was moved or deleted
  • The plugin was installed into the wrong folder
  • You are using a 32-bit DAW with the 64-bit plugin (or vice versa)
  • Antivirus software blocked or quarantined the DLL
  • The DAW does not have permission to access the plugin directory

How To Fix PitchProof-x64.dll Issues

1. Place the DLL in Your DAW’s VST Plugin Folder

Examples:

C:/Program Files/VSTPlugins/
C:/Program Files/Common Files/VST2/

Make sure the folder matches the type of plugin (VST2/VST3) your DAW expects.

2. Rescan Plugins in the DAW

Most DAWs (FL Studio, Reaper, Cubase, Ableton, Studio One) require a plugin rescan to detect new or restored DLLs.

3. Match Architecture (x64 Only)

PitchProof-x64.dll only works in 64-bit hosts. If your DAW is 32-bit, use the 32-bit version of the plugin instead.

4. Restore the File From Antivirus Quarantine

If blocked, restore the DLL and allow-list the plugin folder.

5. Reinstall the PitchProof Plugin

If the plugin came with an installer, reinstalling ensures all support files and registry entries are correct.

Manual Install Instructions

If you obtained a clean, verified copy of PitchProof-x64.dll from DLLme, you can reinstall it manually:

1. Place the DLL in Your VST Folder 

C:/Program Files/VSTPlugins/
C:/Program Files/Common Files/VST2/

Or any custom folder your DAW is configured to scan.

2. Rescan Plugins

Open your DAW and run a plugin rescan so it detects the restored DLL.

3. Use the Correct Plugin Architecture

Only use the x64 version with a 64-bit DAW.

Summary

PitchProof-x64.dll is the 64-bit VST plugin module for the PitchProof pitch-shifting/harmonizing audio effect. It is required for DAWs to load and run the plugin. If the DLL is missing or corrupted, restoring it to your VST folder and rescanning plugins typically resolves the issue.

Fixes and Solutions

The first step in resolving DLL errors is to completely uninstall the affected software and reinstall its latest version. We know this does not always solve the problem, which is why DLLme exists. If reinstalling the application does not help, or if you are unsure which app is causing the error, follow the steps below. These are the most common solutions for fixing pitchproof-x64.dll errors.

  • Repair Windows: Make sure Windows is fully updated, then open Windows Terminal or PowerShell as an administrator (search for “PowerShell” in the Start menu, right-click it, and choose “Run as administrator”). This allows you to repair the Windows component store and run the System File Checker (SFC).

    Repair the Windows component store so SFC can pull clean files:

    DISM /Online /Cleanup-Image /RestoreHealth

    Scan all protected system files and automatically repair problems:

    sfc /scannow
  • Uninstall & Reinstall: On this DLL page, check the Company/Product section to identify the related app, then fully uninstall it. If you plan to continue using it, reinstall the latest version. Be sure to save or back up any important data before uninstalling. Windows or antivirus software may sometimes quarantine DLL files, especially if the DLL is unfamiliar or appears suspicious. Check your antivirus quarantine or logs to determine if this is the cause of your issue.
  • Download the DLL: Download the latest 32-bit or 64-bit version of the DLL directly from our repository using the download button above. Most users will need the 64-bit version, but if you are unsure, or if a 64-bit version is not available, you can install both the 32-bit and 64-bit DLLs. DLLme verifies DLLs that come from our admins, partners, and trusted affiliates. User-uploaded files may be verified later if a trusted source is confirmed.
  • Register the DLL: Most DLL files do not need registration, but some DLLs are COM components and must be registered to work correctly. If registration is required, open Windows Terminal or PowerShell as an administrator.

    Register the DLL (you can also drag the DLL file into the window to automatically fill in its full path): 

    regsvr32 "C:\path\to\pitchproof-x64.dll"

    If you are registering a 32-bit DLL on 64-bit Windows, use the 32-bit RegSvr32: 

    C:\Windows\SysWOW64\regsvr32 "C:\path\to\pitchproof-x64.dll"

    Or open Windows Terminal/PowerShell in the DLL’s folder and run: 

    regsvr32 pitchproof-x64.dll

How to Install pitchproof-x64.dll

To install pitchproof-x64.dll, place the DLL file in the appropriate Windows system folder or in the same folder as the application’s .exe file. If you are not sure which version (32-bit or 64-bit) to use, you can safely install both.

On 64-bit versions of Windows, place 64-bit DLL files in:

C:\Windows\System32\pitchproof-x64.dll

Place 32-bit DLL files in:

C:\Windows\SysWOW64\pitchproof-x64.dll

Or place the DLL file next to the application’s .exe:

C:\path\to\exe\pitchproof-x64.dll
