May be you are looking for this audio effect:
MediaPlayer1.Audio_Effects_Enabled = true;
MediaPlayer1.Audio_Effects_Add(-1, VFAudioEffectType.PitchScale, true);
MediaPlayer1.Audio_Effects_PitchScale(-1, 0, VFFFTSize.Fts1024, 950, 8, false);//The param value 950 you can change it.
But you need to attention.Enable audio effect maybe will let you application crash or stuck when play a lot media file.

MediaPlayer1.Audio_Effects_Add(-1, AE_Tempo, True);
MediaPlayer1.Audio_Effects_Tempo(-1, 0, 500)

Are you kidding me? Why you use Tempo?
I already told you use PitchScale. that is the Effect KTV use.
if you use Tempo , the correct result is change to slow or fast. if you just change audio , you need to use PitchScale.

I need to slow down the video without changing the pitch. using pitchscale changing pitch.
I tried component of other developers could slow down the tempo without changing the pitch, with DirectShow, video and audio sync

Hello
I have some problem with pitch scale (vouce men to child / child to men) for KTV
declare when open the file.
I'm using Active-X for Delphi
MediaPlayer1.Audio_Effects_Enabled := true;
MediaPlayer1.Audio_Effects_Clear(-1);
MediaPlayer1.Audio_Effects_PitchScale(-1, 0, Fts1024, 950, 8, false);
change the pich scale after play with this code
MediaPlayer1.Audio_Effects_PitchScale(-1, 0, fts1024, tbBalance2.Position, 8, false);
the result is no sound
Please advice
