Thanks a lot. It works perfectly! I agree with you, it is wrong, but for a practitioner the result counts and not whether the tools are wrong in theory, but useful in practice. ;-) |

It is feasible and a change has been checked into GIT. Please report any anomalies if there are any. ....but to quote a person who uses a different NLE -- "it is just wrong!" |
|

Does that mean it's not technically feasible? |

GG writes: This is because I was trying to save as much info as possible. When you delete the sign bit, one bit of every sample is lost. The double line version (as opposed to a solid bar from the baseline) preserves the min value during that audio fragment. The heavy line is actually a bar drawn from the min to the max (abs() in the case of rectify). By drawing a solid bar, the min value is lost, and half of all of the data is not represented in the waveform drawing. |

Thank you for adding this new view of the waveform. For me it is sufficient in the timeline. The reason for this representation is that at a glance you'll be better able to see the quiet and noisy parts of an audio piece. In the professional video editing software it is the default view. In a normal waveform, however, the centerline is the zero point. You always have to imagine the center as the zero line, i.e. that's where it's quietest and that's a bit more cumbersome. With rectify waveforms, the bottom of the timeline is the zero line, i.e. the quietest, and the top is the maximum volume. This is easier for the human brain to understand. In true rectify waveforms, there are no empty spaces below the line. However, in the current representation there is black space below the audio line. But this does not exist in rectify waveforms. It is always a completely filled area. I also have the impression that the lower half of the audio waveform has been cut off. The lower half of a real waveform is folded up in the rectify waveform at the zero line and placed together with the upper half of the waveform, this information is also important because you also have peaks in only one half and this visual information would be lost. The lower and upper half of a waveform form a common image.

A mod to provide this alternative for the Timeline ONLY audio waveform was checked into GIT on Saturday the 13th. It is a flag in Settings->Preferences, Appearance, "Timeline Rectify Audio". Once you hit OK or APPLY, you still have to redraw any media already loaded on the timelie before it takes effect (easiest way is to just reload that). As stated it ONLY applies to the Timeline. There are no plans to incorporate this anywhere else in Viewer or Resources. The Rectified waveform is not a true 100% audio waveform and possibly it is used in other programs for simplification purposes. |

Can not commit or predict the future, but GG says he thinks he can pull off taking the absolute value to make this a preference. ;-) |

+ 1 I also think that rectified waveforms add a touch of modernity and are even more clear. Maybe offering the two possibilities of representation, for those who prefer the old method. |
