I found out about speakertest on #Linux and had a brief bit of fun with #PowerShell background jobs and #WhiteNoise.

Warning: this accidentally proves how to make a waterfall of white noise.

#cybersecurity warning: First red team that uses this is getting thrown shade.

speakertest - middle c downwards, and then middle c upwards. Computer generated. The volume of all notes should be the same. Lots of overtones and vibrations. (Choose your terms. :) ) The quality of each is wonderful.

To be fair, I found out about this a bit by accident.

I was looking to play a puretone, which speakertest can also do. Also plays sound files. Very handy little app.

IMO _terrible_ default setting to make white noise.

At least make me use a switch or something 😂

Speaker quality is a pleasant surprise! 🔊

Louder and crisper than the iPhone 15 Pro, even at lower volumes. 🎶

Using only Nothing earbuds was great, but missing swipe controls & stronger noise canceling. 🎧
