When zooming on fluid.waveform~ small values are reduced and tend to be zeroed.
For each picture a fluid.waveform~ is on top and a regular waveform~ on bottom.
The loudness of the whole buffer is in blue . The median loudness for the 128 segments to which the buffer is divided into is in red. The waveform~ displays the median loudness (but on a linear scale obviously).
The first couple displays the waveform with a zoom factor of value 1.
The second couple displays the waveform with a zoom factor of 0.31. Between 1. and 0.31, the red values have gone down, reaching even 0. for some.
The areas circled in green allow to compare values for two specific positions.
