Hello!
I have a new question.
If I save an Audacity file as audio (either the whole of the file or each track) as audio wav file, I want that the duration of each the wav file is exactly as long as the original file, although the Audacity file or at least most of the tracks start or end with silence. I want that the wav files always start with 0:00:000 of the original aup file. How can I make it sure it happens like that? Now, if I make an audio file, it always starts from the start of the sounds, not from original 0:00:000.

Add a little silence to all of the tracks, then the tracks remain in-sync when exported as individual WAV files...
Select all the tracks,("Ctrl"+"A"), move the cursor to the start, ("J"), then generate, say, 0.1 seconds of silence.

correcting unwanted low frequencies

Post by Electric_Dreamer » Thu Feb 15, 2018 6:00 am

Thank you for answer.

I have again a new question.

I have some recorded and mixed sounds which need correction.
Is there this kind of operation: "Filter (= make inaudible) frequencies which are under 200 Hz"?

more about equalisation

Post by Electric_Dreamer » Thu Mar 08, 2018 11:54 am

Thank you for last answer. It was a great help. It leads to the next question, which is this:
Is it possible to make the frequency limits slide from situation of picture 1 to situation of picture 2 (for example during the minute from 05:00:000 to 06:00:000)?
I hope you see the pictures which I attached.

Create two in-sync versions of your track, (to create an in-sync duplicate-track press "Ctrl"+"D").
Apply one equalization curve to one version, apply the other equalization curve to the other version.
Then crossfade between the two tracks.

Easter Questions

Post by Electric_Dreamer » Fri Mar 30, 2018 7:30 pm

Hello.
I wish you a Happy Easter.
A friend has been helping me with synthetic sounds, for example sine-wave. The picture shows some of the curves on which all parameters of the project are based. The parameters are frequency, amplitude, wave form (sine...saw), resonance and cut-off. But now the friend is busy. Is there any way to use the curves with Audacity? Of course the curves are only a way to think about it, the essential thing is that all parameters glide and slide there own way.
Other questions: Does Audacity have a fast command which makes the cursor go exactly to the middle of the selection? Does Audacity have resonance and cut-off effects? Can waveform be modified (example: sine wave becomes gradually saw wave)? I don't mean in this case cross-fade.
I hope you understood my questions.

Nyquist etc

Post by Electric_Dreamer » Thu Apr 05, 2018 1:22 pm

P.S. Perhaps my questions, which I wrote in Easter, were too difficult. But I think Mr Nyquist is answer to many of my questions. I must search my Lisp book. Can you please tell me the best possible website (URL) which has the manual about using Nyquist prompt?

There are plenty of free VSTi synthesizer plugins ...

Now the bad news: they don't work in Audacity.

Herr Nyquist

How about Nyquist prompt? In which URL (www...) are the best instructions about using it?
