====== Add Reverb to an Audio File Using SOX ====== FFMPEG is great for videos, but there is a simpler way this time. To add effects like reverb in a simple way without downloading convolution reverb files, we can just use ''sox''. sox "in.wav" "out.wav" gain -2 reverb 40 50 40 In this case, we first lower the gain a bit to make up for the fact that reverb makes the signal a bit louder.\\ Then, we apply the reverb effect. The parameters in this order are: * Reverberence * HF damping * Room scale * Stereo depth * Pre delay * Wet gain Provide the first N you want.
