## Examples

    adif  diff      asrc                ; emphasize the highs
    anew  balance   adif, asrc          ;   but retain the power
    agate reson     asrc,0,440          ; use a lowpass of the original
    asamp samphold  anew, agate         ;   to gate the new audiosig
    aout  tone      asamp,100           ; smooth out the rough edges
