Oscilloscope Music Visualization

Any chance to directly integrate oscilloscope music visualization into Roon?

Currently i am using https://dood.al/oscilloscope/ in Chrome and Soundflower on the Mac, but it would be nice if it would be directly integrated into Roon. This is not only about nice visuals, but it allows to visually inspect dynamics, headroom and brickwalling of tracks. In my opinion this would also be a huge marketing opportunity for Roon since those visualization are just spectacular. This could be integrated into the album info or as a tab.

BTW: In Chrome you need to change the sound input source to your sound loopback device, e.g. Soundflower (2Ch):

You can then create a grouped zone with your output device and Soundflower (2Ch).

Here’s a screenshot running oscilloscope music in Chrome on the Mac with Roon as a sound source:

Takes me back 20 years whenthis was common in players.

This would be a fun feature.

This is the best looking oscilloscope simulator so far. The source code is here: https://git.s-ol.nu/xxy-oscilloscope/tree/master/
Not sure about the license.

Good old WinAmp times!


Maybe Roon could also include “picture-in-picture” functionality, we could then watch our favourite “soap” while listening to our favourite artists, multitasking :wink:

@PixelPopper: As i already wrote, this is not a gimmick! This visualization tells you more about the quality of the recording than all dynamic range measures. You can immediately see stereo separation, dynamics, loundness, brickwalling, headroom etc.

Aren’t the flappy things on the side of your head supposed to do all of that?


Hmmm, my own multitasking powers would not be up to the task of identifying all that, admiring the pretty simulations and enjoying the music at the same time. :wink:

Those flappy things on the side of your head have a much lower bandwidth than your eyes. And they are easily cheated.

So if you can’t hear the things you are looking for what difference does it make?

I did not say that you can’t hear differences in sound quality, but you might support your hearing with a visualization. That why we have spectrum analyzers and stuff.

No we mainly have spectrum analysers for the pretty lights :sparkler::fireworks:

We are talking about Roon, i.e. Audio control & playback software & Sound Quality. In the context of Design, Build, Test & Setup the oscilloscope can be a useful (Essential) tool during those processes. When listening to music, why on earth would you want the distraction of a “light show” when trying to listen to the music?

@ged_hickman1: yes, also for the pretty lights :slight_smile:
@PixelPopper: For example, if you have multiple recordings of an album, you might confirm which one was better mastered.
Why would you want to be distracted by album art, lyrics, artist info, dynamic range info, …? If you don’t want to be distracted, just don’t turn it on.

@Klaus_Engel what expressions have you come up with? When I try to change up the expressions, I get little joy.

goes a little bit towards fun.

I like https://butterchurnviz.com/
but not sure it has any value of ‘visually inspect dynamics, headroom and brickwalling of tracks’.

Eric, do you mean that you use the signal generator?
I am not using any math expression with the signal generator. I directly link to XXY Oscilloscope microphone input from the music playing from Roon. This can be done using audio routing software. I am using Soundflower (https://github.com/mattingalls/Soundflower) on Mac to wire the sound output to the input.
These are the settings i prefer (signal generator functions do not matter):

Plus 1 for a Roon Visualiser… I know it’s corny - but I sort of miss the visualiser that was bundled with iTunes… Now we can output the roon screen onto an external monitor (or projector) it would be nice to have a range of visualising screens to choose from in addition to the “now playing” piece…
Otherwise with a wholly digital transport into active speakers - I’m looking to find a stand alone box that has a microphone input and an HDMI visualiser output… maybe time to get my Raspberry Pi project brain in gear…
