Pitch shift both tx and rx audio streams on a channel.



exten => 1,1,Set(PITCH_SHIFT(tx)=highest); raises pitch an octave

exten => 1,1,Set(PITCH_SHIFT(rx)=higher) ; raises pitch more

exten => 1,1,Set(PITCH_SHIFT(both)=high) ; raises pitch

exten => 1,1,Set(PITCH_SHIFT(rx)=low) ; lowers pitch

exten => 1,1,Set(PITCH_SHIFT(tx)=lower) ; lowers pitch more

exten => 1,1,Set(PITCH_SHIFT(both)=lowest) ; lowers pitch an octave

exten => 1,1,Set(PITCH_SHIFT(rx)=0.8) ; lowers pitch

exten => 1,1,Set(PITCH_SHIFT(tx)=1.5) ; raises pitch
