MPC-HC has built-in shortcuts for speed adjustment that work out of the box in most standard configurations.
As you press the Up Arrow, you will notice the video moves faster, but the audio attempts to correct itself so the voices remain intelligible.
To understand why MPC-HC is special, you first need to understand the problem. When you play audio back faster, the frequency (pitch) rises. To play a 1kHz tone at 2x speed, you are effectively playing a 2kHz tone. For music, this changes the key. For dialogue, it turns baritones into sopranos.
To solve this, players use time-stretching algorithms (also known as pitch scaling). These algorithms chop the audio into tiny windows, overlap them, and cross-fade them to maintain the original frequency while reducing the duration.
Most free players use low-quality "linear" interpolation. MPC-HC, however, offers professional-grade algorithms.

Title: How to Speed Up Video in MPC-HC Without the Chipmunk Effect mpc hc speed up without pitch
Intro Media Player Classic Home Cinema (MPC-HC) is a lightweight powerhouse, but one common frustration is audio pitch shifting when speeding up playback. Here’s how to watch lectures, tutorials, or podcasts at 1.5x or 2x speed while keeping voices natural.
Step-by-Step Instructions
Method 1: The Keyboard Shortcut (Fastest)
Note: By default, this changes pitch. You need to change one setting below.
Method 2: Enable "Pitch Correct" (The Fix) To prevent the chipmunk effect, you must turn on audio tempo correction:
Method 3: Custom Speed with Presets
Troubleshooting
Pro Tip: Use Ctrl + Left/Right arrow to jump backward/forward 10 seconds while keeping the same speed.
MPC-HC is an excellent tool for consuming content efficiently. By enabling the SoundTouch time-stretching feature, you can breeze through lectures and movies at 1.5x speed or faster while keeping the audio natural and easy to listen to.
Quick Recap:
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
: Close and reopen your video to ensure the new renderer is active. How to Control Speed MPC-HC has built-in shortcuts for speed adjustment that
Once configured, use these default hotkeys to change speed while maintaining original pitch: on the numpad). Down Arrow on the numpad). Reset to Normal Playback rate
: If you are using a very old version of MPC-HC (v1.7.13 or older), this feature may not work as well. It is recommended to use the modern, maintained fork available on for specific playback speeds? Media Player Classic - Home Cinema 2.5.5 - Neowin 31 Oct 2025 —
Most users fail at MPC-HC speed up without pitch because they simply press the increase speed hotkey (Ctrl + Up) and accept the default behavior. By default, MPC-HC does not preserve pitch. You must toggle a specific setting.
Here is the step-by-step configuration:
Important Caveat: This setting alone does not automatically preserve pitch. It enables the resampler. The actual pitch preservation is managed by the "Internal Audio Renderer" or by the "MPC Audio Renderer" (a separate external filter). If you only check the box above, you may still hear pitch shift.
Unlike some modern players that bury this setting, MPC-HC makes it relatively accessible, though it requires a specific configuration to work correctly with modern file formats (MKV, MP4). As you press the Up Arrow, you will
