Simple audio utility for Norns
This script is very basic and my first attempt at creating anything for Norns, so you can lower your very high expectations now
Currently all it does is let you to take any audio file and normalize, auto trim silence from the beginning, and save over the original file, or as a new file with “_norman” appended to the end. It uses SoX for processing (thanks to @zebra for the suggestion) .
NOTE: Use caution with the “trim silence” option - especially when “overwrite” is set to “yes.” You may lose some of the attack of the initial transient. If you are working with very quiet recordings and using “trim silence”, I recommend also using “normalize”.
My motivation was to provide a way to prepare tape samples for loading into other scripts. I have some direct guitar recordings that are way too quiet, and I wanted to easily boost the volume without having to import them into a DAW.
I have a number of features I would like to add, but I may not be smart enough to implement all of them. They include:
- Steal @markeats waveform visualization from Timber so you can manually trim start and end points.
- Auto chop samples by time division or transient detection
- Create “sample chains” by concatenating all files in a directory into a single audio file. This is popular among Octatrack users, and could be interesting for loading into MLR or another sampler.
Any help/feedback/suggestions are more than welcome!
to install SoX, SSH into your Norns and run
sudo apt-get update
sudo apt-get install sox
I was not able to install it without running
apt-get update first.
Use encoders 2 and 3 to select and change parameters. Use key 3 to open and process a file.
