Frequently asked questions
Is it really free?
Yes. There is no paid version, no account and no ads inside the app. The code is open source under the GPL 3.0 license and you can review it on GitHub.
What is VB‑CABLE and why does it need it?
It is a virtual audio device made by VB‑Audio. Audio Pitcher sends the sound of the chosen app to that cable, shifts its pitch and plays it back on your headphones or speakers, so you only hear the modified version. The installer adds it for you. VB‑CABLE is donationware: if you find it useful, you can support its authors at vb‑audio.com.
Windows says "Windows protected your PC". Is it safe?
That warning shows up for new apps without a paid digital signature. Click "More info" and then "Run anyway". All the code is published on GitHub for anyone to review.
Do I need to restart my PC?
Only the first time, if the installer added VB‑CABLE. Updates don't ask for it.
I hear nothing or the sound is doubled. What do I do?
If you just installed it, restart your PC once. If you hear nothing after closing Audio Pitcher, Windows may have set VB‑CABLE as your main output: open the sound settings (speaker icon on the taskbar) and pick your headphones or speakers. Also check that the output in Audio Pitcher's settings is not "CABLE Input".
Which apps does it work with?
Any app that plays sound: Spotify, browsers, Discord, media players and games. In browsers the change applies to the whole browser, not to a single tab.
Does it change the speed too?
No. The pitch changes and the tempo stays the same, so the song lasts just as long.
What is the formant?
It is the timbre of a voice. If you raise the pitch a lot, voices sound thin and squeaky. Adjusting the formant separately keeps a more natural timbre, or exaggerates it if you want an effect.
What do I need to use it?
Windows 10 (version 2004 or later) or 11, 64 bit.
Does it update itself?
When a new version is out, the app lets you know when you open it and installs it with one click. If you'd rather wait, a discreet button stays there for later.
How do I uninstall it?
From Windows Settings, under Apps, like any other program. VB‑CABLE stays installed because other apps may use it; to remove it, use the uninstaller from its official site.
Try it on your PC
One installer, one restart the first time, and you're set.
