To speed up playback in without changing the pitch (avoiding the "chipmunk" effect), you must use the Internal Audio Renderer , which includes automatic pitch correction. Step-by-Step Configuration Open Options Enable Internal Audio Renderer Navigate to Audio Renderer dropdown, select Internal Audio Renderer Adjust Speed Steps (Optional) in the left sidebar. Speed step from "Auto" to a smaller value like (0.1) for finer control. Restart Playback
By default, MPC-HC uses standard system renderers that simply speed up the audio signal, causing the pitch to rise. Follow these steps to fix it: Change the Audio Renderer Open MPC-HC and press Navigate to Audio Renderer dropdown menu, select Internal Audio Renderer (sometimes listed as MPC Audio Renderer Restart the Player must restart MPC-HC for this change to take effect. Adjust the Speed Increments (Optional but Recommended) The default speed jumps are often too large (e.g., 2x, 4x). Go back to Change the Speed step from "Auto" to a smaller percentage like mpc hc speed up without pitch
Follow these steps to configure the "MPC Audio Renderer," which includes automatic pitch correction. To speed up playback in without changing the

You must restart MPC-HC for this change to take effect. 2. Configure Speed Increments
No real-time pitch-preserving algorithm is flawless. Even professional software like or Audacity can introduce smearing or phasing artifacts. However, MPC-HC's implementation—particularly with the external MPC Audio Renderer—is among the best available for free, lightweight video playback.
