without changing the pitch (the "chipmunk effect"), the consensus among users and experts is to switch the to a modern internal option that supports time-stretching . Core Solution: Change Audio Renderer
Check the box that says (sometimes labeled as "Use pitch correction" or "Time Stretch" depending on your exact MPC-HC fork version).
However, most casual media players fail at this task. Speed them up, and suddenly the actors sound like chipmunks on helium. This is where separates itself from the pack.
Look for the option labeled and ensure it is checked. mpc hc speed up without pitch
If you plan to watch everything at 1.5x speed or higher, turn off hardware decoding for audio. Go to Options > Internal Filters > Video Decoders and set "Hardware Decoder" to None (or use "D3D11" only for video, not audio). Let the CPU handle the audio timing.
How to Speed Up Playback in MPC-HC Without Changing the Pitch
Ensure is active under the transform filters. without changing the pitch (the "chipmunk effect"), the
According to user reports and developer discussions on GitHub, the pitch correction feature of the MPC Audio Renderer works perfectly for many audio formats but has limitations with others. Specifically, it may not work as intended with audio. It typically functions correctly with the following formats:
To solve this, players use 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.
As you increase the speed to 1.25x, 1.5x, or 2.0x, you will notice that voices sound completely normal, just spoken at a much faster pace. Troubleshooting Potential Issues Speed them up, and suddenly the actors sound
Press Ctrl + Down Arrow (decreases speed by increments of 0.1x).
As you press these shortcuts, you will notice the video and audio speed up instantly, but human voices will retain their natural tone and depth without any pitch distortion. Troubleshooting Audio Artifacts at High Speeds
