AudioKit export file with Filters

问题

i want to override an existing .m4a file with many filters with audio kit, my code :

file = try AKAudioFile(forReading: recordVoiceURL)
        player =  AKPlayer(audioFile: file)

        delay = AKVariableDelay(player)
        delay.rampTime = 0.5
        delayMixer = AKDryWetMixer(player, delay)

        reverb = AKCostelloReverb(delayMixer)
        reverbMixer = AKDryWetMixer(delayMixer, reverb)
        booster = AKBooster(reverbMixer)
        tracker = AKAmplitudeTracker(booster)
        AudioKit.output = tracker
        try AudioKit.start()

i am changing the values of my filters and it works perfectly , now i need to export a new file which include my original file + the EQ filters applied but i don't know how with AudioKit or with AVFoundation

Thanks to all

Try AudioKit's renderToFile once you have your filters setup:
