Is there any way to make stereo track in a batch way?
I know i can get one audio, duplicate the track and merge into stereo one. But how do the batch process for that?
I only can find chains for mainly FX, but nothing for that, or missing something? For example there is a FX for StereoToMono but not the opposite.
I have various .wav files which are mono. I want to convert them into stereo, 2 channels, so i can after use the FX chain to give a better stereo feel with phaser and other stuff.
Nevermind i found it!
I was using 2.1, and now in 2.3.3 there is a “macro” feature.
So i just make new stereo track, select all and mix and render and does the batch perfect.
Here a screenshot of the Macro:
I think your macro could be even simpler.
Exporting automatically mixes down all non-muted tracks in the project, so all you need to do is add a stereo track, and export.
Oh you right! I was testing the macro without export so i need that options, but yes, just adding a new stereo track does the works, thanks! .
I’m glad you posted. This is a very good example of a very simple Macro, so I’ve added it to a page of examples on the Audacity wiki: https://wiki.audacityteam.org/wiki/Macro_Examples
This is a new page, so if you are interested in Macros, you may want to revisit it in the future as I am still in the process of adding examples. (Please do post here on the forum if you spot any errors
Oh great! Sure! I’m interested in the macros thing and batch export, i’m using it in an intensive way right now .
And another thing about macros, is possible do a batch export of an audio with random params giving min/max?
From a .wav, export X times(like 20, 50 or whatever) with:
Freq: 0.1- 0.7
So you will have :
audio1.wav > With PhaserFX | Stage:08 | Wet: 210…
audio2.wav > With PhaserFX | Stage:21 | Wet: 240…
And do this with multiple FX? Like Phaser + Reverb? So on reverb you also give min-max for room size,etc…
Now i play moving sliders to get cool effects, if i found one then i export, select name,etc… With this i can just give the random values and export 100, after that just listen and pick the cool ones. So, its a way to generate random SFX. Also maybe give some % of the effect be finally added so, some sounds will have phaser/reverb/echo, others only echo+phaser, ,etc…
I know maybe is too much, just asking!
You can’t do anything random with an ordinary Macro. Ordinary Macros are strictly a list of commands that run one after another. There’s no logic other than step 1 => step 2 => step 3…
For more complex tasks, Macro scripting commands can be run from a Nyquist script. These are called “Nyquist-Macros”. They are more “advanced” than normal Macros, both in how easy / difficult it is to write them, but also they are much more flexible. There’s an introduction to Nyquist-Macros here: https://manual.audacityteam.org/man/nyquist_macros.html
