AB  - Acoustic feedback is a longstanding problem in the audio processing field, occurring whenever sound is captured and reproduced in the same environment. Different control strategies have been proposed over the years, among which a feedback cancellation technique based on the prediction error method (PEM) has revealed to be performing on purpose. Recent studies have shown that the integration of a suppression or a noise reduction filter in the system loop might be beneficial from different perspectives. In this contribution, a real-time implementation of the aforementioned algorithm is presented, which exploits the partitioned-block frequency-domain (PBFD) technique to allow the system to work also with long acoustic paths. NU-Tech software platform has been used on purpose for real-time simulations, performed over synthetic and real acoustic conditions.
