slow-down effect

[Patrick Spendrin]

Hi everybody,

I am looking for a special effect in the phonon backends:
My application should replay the media file slower than originally (so
that the user can better understand human voice in the audio file).

Is this possible with any backend atm (I checked phonon-vlc and
phonon-gstreamer and there doesn't seem to be an effect like that)?
Is this possible with one of the backend backends?

regards,
Patrick
