How to enable pitch shifting in MPC?

Question

How can I enable pitch shifting in MPC? I read in Wikipedia that Media Player Classic has pitch shifting but it seems it's not enabled (doesn't work?). I was wondering I have to do something to enable this feature, maybe I have to use some kind of custom decoder for audio?

Note, by pitch shifting I mean something like YouTube where if you make the video faster, the audio also gets faster without losing its quality.

Answer 1

This feature was implemented in the Time stretching ticket and applies to MPC's internal renderer. You can enable it by going to Options > Playback > Output > Audio renderer and choose Internal Audio Renderer (or MPC Audio Renderer in newer versions)

See MPC-HC - How to increase/decrease video speed without changing the pitch of audio?

Answer 2

phuclv's answer already provides the detailed solution. In short:

• In "Options... > Playback > Output", select "MPC Audio Renderer", and restart MPC-HC.

However, you may also need to reduce the "Increase Rate" steps, as they are initially way too large.

• In "Options... > Playback", change "Speed step" from "Auto" to something like 5% or 10%, according to your personal preferences.

Additionally, for a few years (initially an advanced setting, refs #830 – nowadays integrated in the options, refs #2440) you can have the playback speed displayed in the status bar when it is different from 1x:

• In "Options... > Player > User Interface", section "Status Bar Elements", check "FPS".
