If the speed jumps too drastically (e.g., from 1.0x straight to 2.0x), you can make it more gradual: In , go to Playback .
However, the "Chipmunk Effect"—the high-pitched, distorted audio caused by simply playing media faster—is a dealbreaker. No one wants to listen to a professor who sounds like they've inhaled helium.

If you enable "Time stretch" and your audio still speeds up (chipmunk effect), it means an external filter is bypassing MPC-HC's internal switcher.
Here is the step-by-step process and an explanation of the underlying mechanics. How to Enable Pitch Correction in MPC-HC If you prefer using or DirectSound for your
The default speed steps are often too large (e.g., doubling speed from 1x to 2x). To make smaller adjustments: Go back to Speed step Change it from "Auto" to a smaller value like to allow for gradual speed increases (e.g., 1.1x, 1.2x). 3. Playback Controls Use these keyboard shortcuts to control the playback rate: Increase Speed Decrease Speed Down Arrow Reset to Normal (1x) Troubleshooting
Check the box for . This is the critical setting that prevents the chipmunk effect by dynamically adjusting the pitch back to its baseline frequency during fast playback. Click Apply and then OK to save your changes. Method 2: The Sanear Audio Renderer Method
Unlike some modern players that simply fast-forward, MPC-HC uses smart audio processing to maintain the original pitch while increasing speed. Here is how to set it up and use it effectively. Change the selection from your current default to
MPC-HC, the lightweight Windows veteran, handles "speed up without pitch shift" better than almost any consumer player on the market—provided you know which engine to use. Here is the definitive guide to accelerating your playback without turning human speech into gibberish.
