How do you use AI for feedback suppression in live sound?
Quick answer
SSOUNDS uses AI-driven feedback suppression by analyzing the audio signal in real time, identifying resonant frequencies, and applying precise notch filters before feedback becomes audible, ensuring clean, high-SPL output.
Feedback suppression in live sound traditionally relies on manual EQ notching or fixed filters, but SSOUNDS integrates AI that continuously monitors the system's transfer function. Machine learning algorithms detect the onset of feedback by recognizing patterns in phase and amplitude anomalies, then dynamically apply narrow, adaptive filters that preserve tonal quality while eliminating howl.
Our DSP platform uses a neural network trained on thousands of acoustic environments to predict feedback paths. This allows the system to preemptively adjust gain structure and EQ across the PA, rather than reacting after feedback occurs. The result is up to 6 dB more usable gain before feedback, even in challenging room acoustics.
SSOUNDS engineers have embedded this AI directly into our amplifier and DSP modules, making it a seamless part of the system setup. It works in conjunction with our line array and point-source loudspeakers, which are designed for consistent coverage, further reducing feedback risk. This technology is especially valuable in high-SPL events and touring where speed and reliability are critical.
