Nvidia Audio Effects SDK

The NVIDIA® Audio Effects SDK provides the following audio effects for broadcast use cases with real-time audio processing:

  1. Noise Removal/Denoising : Recordings of speech made outside of a recording studio can contain a lot of background noise, which causes the speech to be garbled and difficult to understand. The audio denoising effect removes this background noise from audio.

  2. Room Echo Removal/Dereverb/Room Echo Cancellation : Recordings of speech might contain reverberations from the recording environment, which can affect speech clarity. The dereverb effect helps remove or suppress these reverbs from audio.
  3. Noise Removal and Room Echo Removal/Denoise Plus Dereverb: The effect combines both the above effects to remove/suppress both noise and reverbs from audio. This offers much better performance than applying these effects separately.
  4. Audio Super-Resolution: This effect improves the sound quality by adding higher frequency content to the audio stream. For low-frequency audio, this feature predicts the higher frequency spectrum of input audio, which improves audio quality.
  5. Acoustic Echo Cancellation (AEC): This effect removes acoustic echo and feedback from audio, which improves the bidirectional audio quality.
