“I changed Audio Renderer to "Internal Audio Renderer" as u/Skodd said, and the results are very good.” Reddit · r/software · 3 years ago
You can also adjust speed via the top menu:
: You may need to close and reopen your video for the new renderer to take effect. Playback Controls & Fine-Tuning
: Press Ctrl + Down Arrow (Decrements speed by 0.1x). mpc hc speed up without pitch
Most free players use low-quality "linear" interpolation. MPC-HC, however, offers professional-grade algorithms.
In the dropdown menu, select MPC Audio Renderer (it may be labeled as Internal Audio Renderer in some versions). Click Apply and OK .
5.1. Low-complexity / Low-latency (casual use, <1.5×) “I changed Audio Renderer to "Internal Audio Renderer"
: Users recommend changing the "Speed step" from "Auto" to a fixed value like 0.1 (10%) or even 0.05 (5%) in the Playback settings. This allows you to find the "sweet spot" where audio remains clear before it becomes difficult to understand.
When a media player accelerates video frames, it natively forces the corresponding audio track to process at an accelerated frequency. In basic sound processing, speeding up audio shortens the acoustic wavelengths. This doubles or triples the frequency of the sound waves hitting your ears.
For the best results, you may want to refine how the player handles speed increments: MPC-HC, however, offers professional-grade algorithms
Follow these steps to enable pitch correction (time stretching) so voices do not sound like "chipmunks" when the playback rate is increased:
Now, when you use Ctrl+Shift+S with the pitch box checked, the external renderer handles the time-stretching with lower latency and higher quality—especially useful for high-speed playback (2.5x or 3x).
