I am trying to apply equalizer filters to ffplay while it is playing an audio. Is it possible?

Like start playing the audio with the command:

ffplay -i foo.wav

Then while foo.wav is playing change it to

ffplay -af "equalizer=f=1000:width_type=h:width=200:g=-10" -i foo.wav

without stopping the audio.
