I was wondering if it is possible (in Audacity) to censor a song using that method. Where like it sounds like a DJ scratch? Because it seems like an easy method to use if you dont have a instrumental.
Initial step: [-36 - +36 semitones, default 0] - the resulting pitch change at the start of the selection, defined as number of semitones above or below the original pitch (1 step = 1 semitone, so 12 steps = 1 octave.)
Initial amplitude: [0 - 100 percent, default 100] - the resulting volume at the start of the selection, related to the original amplitude (so 100% = no change).
**Change time: [0 - 100 percent, default 50] - the point in time in the selection (set internally to the original pitch and volume) at which the warping values change to reach and move away from this point. What this means is that depending on your start and end step and amplitude values, you can design warps that slow down then speed up; speed up then slow down; speed up to a particular pitch then remain there; slowly speed up then quickly speed up.**End step: [-36 - +36 semitones, default -12] - the resulting pitch change at the end of the audio. compared to the original pitch.
End amplitude: [0 - 100 percent, default 40] - the resulting volume at the end of the selection, compared to the original volume.
How do you design a warp that slows down and speeds up? Can anyone tell me what settings to use?
Change time ? (the point in the selected portion of track at which the warp begins,
e.g. 50(%) => effect begins half way into the selected portion of the track, 75=>effect begins in last quarter of selected part of track)
End Step ? (for slow down use negative values)
End amplitude 100 (100 => effect doesn’t change volume)
As I mentioned previously in this thread, unless you have access to the vocal track alone, without music,
applying the effect will warp the vocal and the music, which is not the same as the effect on the video where only the vocal is warped.
Reversing part of the swear word is easier than warping : here I’ve reversed “ong” of “songs” …
The timing is not changed by reversal, (whereas warping changes timing).
Just select part, not all*, of the swear-word, reverse it, “Reverse” is in “Effect” menu, then use “Repair”, (also in “Effect” menu), on either end of the reversed bit so there is no click.
You should only reverse part of the swearword so even if the track is played backwards (reversed) the whole swearword will not be heard.
That’s better than turntable warp plug-in for this censor task as it keeps the original timing after the warp, ( the speed-up must exactly cancel-out the slow-down).
The only restriction I noticed is it refused to process selections longer than two seconds, which is not a problem in this censorship application, unless there is a two second profanity I don’t know about.
Yes. The maximum duration that can be processed is 100000 samples.
The technical information about this is that Nyquist in Audacity has the maximum size for a “wavetable” hard coded as 100000 samples.
If I get round to making a plug-in version of this I’ll have to remember to add an appropriate error message for this.
