🫡 Greetings sound traveller 🔊

Need to normalize thousands of audio files ? Maybe just quickly concert something to 16 bit, 44.1khz? Or record a quick bit... And so much more... All from the command line ? SoX is your friend. A free command line tool for audio manipulation. Honestly, the GOAT of #terminal based audio programs. We have a guide by @madskjeldgaard to get you started.

hyaline.systemsSoX guide: Convert, manipulate and generate audio on the command lineSoX is a free command line audio processing tool with a text-based interface that let's you perform powerful audio operations by typing just a few words in your computer's terminal. It is a popular tool for managing large collections of audio files, splitting audio files by silence and batch processing (eg. normalizing an entire folder of drum sounds in a matter of seconds), but really it is much more than that. If you learn to use SoX you are guaranteed to save enormous amounts of time working with audio files. This guide will help you get started.

💥 NEW BLOG POST: Convert, manipulate and generate audio on the command line using #SoX.

This is an updated, cleaned up and revamped version of my tutorial on how to use #sox to manipulate audio files, batch process them, normalize, etc. etc.

With this, I am moving all my tech blogging to @hyalinesystems website.

@NOISEBOB #HowTo run #ShellScript when sound in mic

Here is a #bash function "getvol" which uses #SoX to listen for 0.1 second and then tells you peak volume, between 0 and 1:

function getvol {
rec -p trim 0 .1 stat 2>&1 >/dev/null | grep -Po "(?<=Maximum amplitude:).*" | grep -Po "\S+"
}

You can loop the function and do something if the volume is high enough.

Aus dem Leben eines Menschen, der seit langer Zeit auf all seinen Computern GNU/Linux laufen hat:

Eben wollte ich im Terminal ein Backup-Script starten. Ich wusste, dass es mit »back…« anfängt, also tippte ich nur back und dann die Tabulatortaste zur Vervollständigung. Eine der Optionen, die mir daraufhin angezeigt wurden, war background-noise-enterprise. Klingt interessant!

Um herauszufinden, worum es sich handelt, habe ich erst mal Folgendes gemacht:

$ type background-noise-enterprise 
background-noise-enterprise ist ein Alias von »play -n -c1 synth whitenoise lowpass -1 120 lowpass -1 120 lowpass -1 120«.

Da fiel mir ein, dass ich vor Jahren (als es Twitter noch gab) folgende Zeile in eine Datei namens ~/.bash_aliases eingefügt hatte:

alias background-noise-enterprise="play -n -c1 synth whitenoise lowpass -1 120 lowpass -1 120 lowpass -1 120"

Dadurch stand das Kommando auf meiner Shell zur Verfügung. Ich habe es ausprobiert, und es funktioniert wie am ersten Tag, als ich es vermutlich aus einem Tweet kopierte. Das Geräusch klingt täuschend echt und ergänzt das Lüftergeräusch vortrefflich.

Voraussetzung ist, dass das Programmpaket SoX installiert ist. Unter Debian heißt das Paket sox. Es wird beschrieben als »Das Schweizer Taschenmesser der Audiobearbeitung«. Oft benutzt man es zum Aufnehmen, Umwandeln oder Abspielen von Klängen. Dass da auch ein Synthesizer eingebaut ist, wissen nur wenige.

Emergence of Sox & POU transcript. factors predates origins of animal stem cells
nature.com/articles/s41467-024

ScienceDailyScientists recreate mouse from gene older than animal lifeAn international team of researchers has achieved an unprecedented milestone: the creation of mouse stem cells capable of generating a fully developed mouse using genetic tools from a unicellular organism, with which we share a common ancestor that predates animals. This breakthrough reshapes our understanding of the genetic origins of stem cells, offering a new perspective on the evolutionary ties between animals and their ancient single-celled relatives.

@alexisbushnell I had an evil time of it earlier this week. Spent a day chasing problems on what all the guides suggested would be simple.

Ended up with a single line of code!

on a raspberry pi with #sox installed and a USB sound card plugged in and identified as "card 3" by alsa, this bash command is everything you need:

sox -t alsa hw:3,0 --buffer 1024 -t alsa default pitch +500 echos 0.8 0.88 100 0.6 150 .5 band 1.2k 1.5k

Change values to taste!
