Each clip was processed using Flixier’s “Remove Background Noise” (default intensity), Audacity’s Noise Reduction (FFT-based profiling, 12 dB reduction), and Adobe Premiere Pro’s “DeNoise” (adaptive mode). Objective metrics (PESQ for speech quality, SNR improvement) and subjective listening tests (n=10 media students) were conducted.
Thanks to Flixier for providing a free trial for testing; no compensation was received. flixier remove background noise
