Nullpane Audio Difference

What changed between these two bounces? Nullpane subtracts one audio file from another so you can see, hear, and export the residual itself. Bring two versions of the same recording from Files. Check the shared time view, adjust B by integer samples, match a constant gain if appropriate, and optionally invert polarity. The offset suggestion searches channel 1 in the first two seconds within ±4096 samples. Listen and inspect the result before applying it. Switch between A, adjusted B, and the difference. See residual RMS relative to A, overlapping duration, actual waveforms, and measured one-second windows. Select a window and inspect a five-second range. The difference waveform can be displayed at ×8; this is a visual scale, not an export gain. Export three real files: an unscaled 32-bit float PCM WAV containing A minus adjusted B, a CSV of second-wise residual RMS/peaks and source…
