What you are currently running (e.g., old standalone, or the modern clsid2 fork)?
Common approaches:
If all else fails and your computer struggles to keep up with high-speed playback while maintaining pitch quality, you might consider using the audio renderer instead of the MPC Audio Renderer. Some users report better efficiency and lower CPU usage with SaneAR on older hardware. mpc hc speed up without pitch
5.1. Low-complexity / Low-latency (casual use, <1.5×)
Here is the complete, step-by-step guide to configuring MPC-HC for chipmunk-free fast playback. Step 1: Switch to the Internal Audio Renderer What you are currently running (e
Without proper configuration, speeding up video (a process called "time-stretching" or "pitch-shifting") can result in the "chipmunk effect," where voices become annoyingly high-pitched. This article will show you how to configure MPC-HC to speed up playback while maintaining natural-sounding audio. The Core Solution: Using the MPC Audio Renderer
Check the box that says (sometimes labeled as "Use built-in audio renderer time-stretcher"). Click Apply and then OK to save your settings. Method 2: Configure the Sanear Audio Renderer (Alternative) This article will show you how to configure

To solve this, we need (or pitch-preserving time scaling). The audio is broken into tiny grains, overlapped, and crossfaded to "squeeze" the duration without altering the underlying frequencies. MPC-HC, via its internal filters and external renderers, handles this surprisingly well—but you must configure it correctly.
