Dear Listers, May be this is a silly question but perhaps there is an intelligent answer to it: What could from a perceptual viewpoint be regarded as an optimal aspect ratio for a sonogram/spectrogram? Imagine the frequency axis scaled logarithmically, so should 1 octave (y-axis) correspond to 1000 ms (x-axis)? Or to 100 ms? Or to 10 ms? Your answer might be "That depends on what you want to show with your figure." But is there any natural choice that would approximately correspond to the perceptual impression one has while listening to sounds? If there is no scientific way to prove the superiority of one aspect ratio, you could give your favorite value. This might stimulate the discussion, and perhaps we end with a scientific argument.
