Hi,
is it possible to convert the waveform of an entire audio file (or a
segment of it) to a picture?
The "showwavespic" filter has the problem that for each sample it draws
a line from +level to -level. For example, if the input is a +0.5 DC
signal, I can't decide from the output picture if the level was +0.5 or
-0.5. I need a filter that draws only a pixel for each sample. Like an
oscilloscope.
