How to Get GSnap to Work With Audacity
The GSnap pitch correction audio plug-in allows you to change the pitch of recorded audio. Because GSnap uses the Virtual Studio Technology platform, it runs in any audio software that includes VST support, including the free, open-source program Audacity. Once you've got GSnap working in Audacity, use it to subtly shift a singer's pitch back into key, or use more extreme settings to create a T-Pain-style effect. Before GSnap can work in Audacity, you must configure the software to scan for new plug-ins, then install the plug-in in the proper directory.
Launch Audacity. Click the "Edit" menu and select "Preferences." Click "Effects," then check the box next to "Rescan VST effects next time Audacity is started." Audacity now scans for new plug-ins when you start it. Click "OK" and close Audacity.
Navigate to the GSnap download page. Click "Download GSnap" and save the GSnap zip file to your browser's download directory.
Click the "Start" menu button, then click "Computer." Locate the GSnap zip file in your browser's download directory and double-click it to open it in Windows Explorer.
Click "Extract All Files." Click the "Browse" button. Navigate to "Program Files," then to the "Audacity" folder. Click the "Plug-Ins" folder, then click "OK." Click "Extract."
Re-launch Audacity. The program scans the plug-ins directory for the newly installed GSnap plug-in.
Click "File," then "Open." Double-click the audio file to which you want to apply GSnap.
Open the "Effect" menu. Click "GVST: GSnap" to launch the plug-in. Select a preset from the "Presets" drop-down menu, then click "Preview" to listen to the effect. Adjust GSnap's controls as desired, then click "OK" to apply the effect to the audio file.
