How to draw a waveform faster in audacity 2.1.3?

Post by lorenzo » Sat Jul 01, 2017 11:37 pm

I have a music here in audacity, and I want to draw the waveform just that much faster without delay, I already added a new stereo track and also generated a silence, so that the problem when I use the drawing tool it seems to be very slow to To draw a complex and large waveform, is it possible to draw a more complex waveform using only Nyquist Prompt codes? Obs I am very new in this nyquist language, could anyone give an example of nyquist code to draw a waveform? thanks

What do you mean by "draw the waveform"?

No, I really need to redraw this waveform just for personal use I want to recreate this music via nyquist prompt I think using the drawing tool to redraw is much slower for this because zooming in and seeing every point in the waveform takes a long time for me

Code in Nyquist prompt can synthesize sounds, see ... http://forum.audacityteam.org/viewtopic ... 31#p326231

Can I import this attachment file into the nyquist prompt? or not? Does it generate a new waveform?

No, that will not work. You have to enter valid Nyquist commands in the Nyquist Prompt. See: http://www.audacity-forum.de/download/e ... /home.html

That data is just an average of the frequencies present in the selected region of the audio.
It doesn't contain enough information to reconstruct the music.

It's analogous to this graph of letter-frequency ...

which is not sufficient to reconstruct the text it was derived from.
