This video was quite interesting as an artist's view on generative AI...

I suppose I would expect any power supply in sensitive equiptment to have surge protection built in, this is why you have to be careful not to PAT test with high voltages.

Also, If I cared enough I would put surge protection in the consumer unit at home.

I think your best bet is to watch some Youtube videos.
Curtis Judd has a nice video on the new Rode system.

I have a Rigol DS2072A. The only thing that irks me is I feel I purchased something nobbled for bandwidth (not that I need it). I like being able to download the traces across a network.

Your Audiofire 4 may not be as dead as you think.

Thanks for that, interesting.
I do have the readmes and installers for 5.5, 5.7.6 and 5.8 on my current PC.
New PC should be here in a couple of weeks.

Yes, the RME is overkill unless it also replaces the external USB interface. That might be technically possible but an interface with XLR/jack sockets etc. is a bit more user friendly than a PCIe card with breakout cables.

Thanks for all the comments.

SPDIF is stereo only - it won't carry surround. That's a pity, so the RME can't do what my existing card does but then it would not be a feature to expect on such a card. Currently I have the Creative sound card set to send Dolby Digital over the SPDIF link and the (ancient) Cambridge Soundworks de...

Should have said, will go for Windows 10 and hang on as long as possible but need to future-proof if I'm forced to Windows 11 at some point later next year.

By "onboard sound" I meant from a chipset on the motherboard. I wonder if I went for the RME, could I connect to the surround system via SPDIF being default windows sound and route specific audio apps (Cubase, wavelab) to the active speakers at the same time? It looks like you need to add ...

I'm wondering if people think that internal sound cards have had their day. Belatedly I'm specifying a new PC to replace one that has the following Creative Titanium X-Fi ECHO Audiofire 4 I can't use the latter (no drivers) but will use a USB external interface. For the internal card I really just u...

No objective tests of ultrasonic cleaners involve audio testing. From hospital CSSD to benchtop devices. Of course. This was more of a thought exercise when I posed it to see if the equipment we use on this forum could detect these devices. It doesn't really matter what you would do in practice if ...

You will know if it is working because the liquid surface generally ripples and a simple test is to put a tarnished silver spoon in there and check after a few mins that it's clean. So I'm not sure that you need anything more sophisticated. It's because it has three transducers, so it would be easy...

Thanks for the suggestions.

Yes Earthworks can do the job (M50), but very expensive and I take the point about likely levels outside.

I do have a recorder that has a 192kHz sampling rate.
And an oscilloscope that goes to 500μV/div.

I'll see what works.

I suppose a transducer is the way to go, although when I looked at those it was not clear which ones generate sound as opposed to detect it. Or just hack a bat detector, you even get cheap kits that must have sensors/microphones in them. A measurement microphone that goes to 50KHz is pretty expensiv...

This might seem a bit crazy but here goes. I'm going to get an ultrasonic cleaner which operates at 48kHz. Is it likely that I could make a recording of this to tell if it is working or if its 'volume' is the same in a year from now. I have various microphones, not sure if I have any spec sheets tha...

The EC2 looks really intersting but this puts me off...

[R11] Power: Provides Camden EC2 with power via the provided external 24v 1A DC power supply. No other power supply should be used.

I have used Jabra headsets for decades, starting with wireless ones that loop into a traditional telephone or analog office telephone, at that time Jabra (I think operating under another name) were only known in office environments. I also use USB headsets for zoom/teams calls and prefer the single-...

I have a similar situation. I'm involved in training events that are often held in rooms with say 20 people and where there may or may not be a PA setup in the room. Presenters stand in front of the class and move around. Even if a room has a professional sound setup with lav or head-worn mics and t...

I have an AW2816 which I don't think has been powered up for 5 years or more. This discussion does make we wonder if it will still work.

Not sure if it helps with change of use but I have found an older version of this document useful in the past (PDF download on page): https://www.gov.scot/publications/house ... 1/pages/2/
