function 'PITCH_SHIFT'
[Synopsis] Pitch shift both tx and rx audio streams on a channel. [Description] Examples: 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 [Syntax] PITCH_SHIFT(channel direction) [Arguments] channel direction Direction can be either 'rx', 'tx', or 'both'. The direction can either be set to a valid floating point number between 0.1 and 4.0 or one of the enum values listed below. A value of 1.0 has no effect. Greater than 1 raises the pitch. Lower than 1 lowers the pitch. The pitch amount can also be set by the following values highest higher high low lower lowest
