Add white/pink/brown noise to multiple samples

Post by martijn94 » Sat Jun 09, 2018 11:55 am

Hi!

I'm working on a Deep Learning experiment which takes as input many single (short) audio files.
For this experiment, I want to have 4 conditions as input:

1. Original audio sample (WAV).
2. Original audio sample + white noise (combined).
3. Original audio sample + pink noise (combined).
4. Original audio sample + brown noise (combined).

I know that it is possible to generate white noise etc. in Audocity, but I'm not able to combine this noise with the original sample and apply a ''chain'' on it.
I've to edit more than 500 samples, so I'm looking for a way to do this automatically...

Could someone give me an advice how to realize this?

Thanks in advance!

I think it's still true Chains can't call other Chains. I think you may need that for this job.

Open the sound file and generate all three noises one above the other. Then SOLO one noise at a time plus the sound clip and Export. I think that's too many Chain levels.


You may be able to open one noise and chain all of the clips through open, export, close [repeat].

Then manually close the first noise and open the next noise > chain all of the clips through open, export, close [repeat].

That gets you down to only three chains. I don't think you can do this with only one.
