I checked the "Keep pitch" box, but the audio sounds warbly/watery. Solution: Reduce the speed slightly. Time-stretching algorithms fail at extreme speeds. Try 1.8x instead of 2.5x. Alternatively, switch to the external MPC Audio Renderer, which handles extreme ratios better.
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
To achieve speed playback without changing pitch, you must replace the default audio renderer with one designed specifically for time stretching. The golden rule is that the internal audio renderer handles pitch correction far better than standard Windows components. Standard Windows renderers, such as DirectSound, have inherent speed limitations and lack the advanced algorithms needed for high-quality pitch preservation. mpc hc speed up without pitch
To see your current playback speed, go to Options > Player > User Interface and check FPS under the "Status Bar Elements" section.
As you press these keys, you will see the speed multiplier display in the bottom-left corner of the player window, and the audio will remain at its original pitch. Direct Comparison: Audio Processing Options Feature / Renderer Pitch-Correction Support Ideal Use Case Yes (Built-in) Fast-watching lectures, audiobooks, and films. System Default / DirectSound No Standard 1.0x playback without speed modifications. SaneAR Audio Renderer Yes I checked the "Keep pitch" box, but the
SoundTouch is an open-source audio processing library specifically designed to change the tempo of audio without altering the pitch. Once this is selected, MPC-HC can handle speeds up to 2.0x with clear, understandable audio.
⚠️ Default commands (without Ctrl) will change pitch. Always use Ctrl + Arrow when time stretching is enabled. Down Arrow on the numpad)
: If you are using a very old version of MPC-HC (prior to the v1.7.x era), these internal renderers may not be available. It is recommended to use the latest maintained version of MPC-HC .
