Techniques are provided in which an audio signal for transmission to a receiving device is acquired at a network device. The audio signal is analyzed for an audio feature to be suppressed or enhanced during playback of the audio signal at the receiving device. The audio feature is detected based on the analysis. The audio signal is encoded for transmission over a network to the receiving device. The encoded audio signal is transmitted to the receiving device. A packet is generated comprising an audio feature descriptor indicating where in the audio signal the audio feature is located to enable the receiving device to suppress or enhance the audio feature during playback of the audio signal. The packet comprising the audio feature descriptor is transmitted to the receiving device.
