Plenty of mics (including some very high end) with horrible RFI behaviour, mostly because mic designers don't in general think like RF types, and leave common impedances all over the shop. It is not hard to make an XLR connected mic pretty much RF immune, it just takes attention to both mechanical ...

In other words, based on your interpretation of what's going on, the cable is helping to mitigate a design flaw elsewhere. Nothing wrong with that, of course, unless the whole thing is grossly over-priced and sold using intentionally deceptive marketing claims... oh wait... ;) H Quite. If brand of ...

I shall make one last attempt... This is goalpost moving. Common mode output from the PSU will have no affect at all on it's own performance. Clearly true as far as it goes, but real audio toys however tend to have other connections to grounded things. Now consider a common switchmode line lump ...

Is this him: http://www.audiosystemsgroup.com/publish.htm? Yea, that's him, see also Whitlock, Tony and Muncy. Your version of Godwin's law :) Pretty much yea, also anyone wittering about Tesla unless discussing Three phase machines or quarter wave transformers can probably be safely tuned out ...

The usual gotcha with powered monitors is that the signal from the phones actually gets picked up by the INTERNAL speaker leads from the power amp board to the drivers, then gets back into the input via the feedback network, no amount of filtering the inputs fixes that.... It can be getting in via ...

Yes but it's not a grounded shield; it's not part of the electrical circuit. Is it?? Actually in a typical UK TN-C-S (MEN, PME, whatever) install it is part of the electrical circuit, specifically the armour carries the neutral current (It is connected to the house 'ground' conductor at the supply ...

8K is a big ask in a portable box. For more mundane things we have a portable Phabrix that is really quite nice (Battery powered, does all the usual 3G sort of things), but for 8K you would be looking at one of their Qx series boxes (Which are nice as they also offer SMPTE 2022-6), whole lotta money ...

You pay the power company for a nice supply of electrons, but it transpires that they actually mostly just make the ones you already have wiggle back and forth slightly (mean drift velocity in copper at any current density you would want to run is measured in mm/s). You paid for an army, but only ...

Thirded, it is just not the big deal it was in the 90s, ADCs these days are almost all good enough to not be the weak link in a home recording setup (Usually it is the room). Talent/Instruments/Room/Mics (including WHERE to put them)/loudspeakers/everything else in that order. The electronics is ...

Top tip if the weather stays hot.... Get thee to a camping shop and clean them out of those foil emergency blankets, add gaffer tape and cover the side and top of the cans facing the sun, makes one hell of a difference (But it will still be ridiculously hot). This is especially helpful if the cans ...

Turns out Dante does not in fact work over a typical wifi network, even without the storm (Just tried it, not remotely surprised)....

Regards, Dan.

feeding a DANTE IP stream which you could link wirelessly back to your network. H Dante over wireless network? In a thunderstorm?? I very much doubt it would work (Dante over wireless is a chancy enough proposition, being as Dante is designed for low latency working). A better (Not to say cheaper ...

Yep, one of the things that DSP makes really easy is quiet, accurate, repeatable filters, DSF-B Mk2 is a bit quieter then the DSF-B Mk1 and both are very much quieter then the old MK-V systems which were all analogue and fairly heroic efforts (Think 4 gang pots with sine/cosine tapers). SPS200 is ...

The thing about Soundfield is that you have to view it as a system, particularly with the older MK V and the like, it really made no sense to speak of the capsules in isolation from the processing. SPS200 is a bit different, as it is natively an A format mic which uses software on your PC to convert ...

Common impedance coupling is a very common gotcha in condenser mics, even from big names, see the following notes : http://audiosystemsgroup.com/AES-RFMicrophonesASGWeb.pdf Also the following, with actual measurements from the inimitable Jim Brown. http://audiosystemsgroup.com/AESPaperNYPin1-ASGWeb ...

The place the cheap digital scopes usually fall down badly is on some combination of memory depth and poor control response, and this tends to be a thing across almost all the manufacturers (Even LeCroy and Tek managed to stuff up that way, to the point I sent a low end LeCroy back as unusable). If ...

In technical matters, ignorance is rarely bliss. But ignorance makes for a much better uninformed rant on youtube, and we have all seen that sort of thing. It is important, for example, when summing an infinite series, where you should start at the small end. Last I checked an infinite series (that ...

When you add floating point numbers, the smaller one is shifted right. So if it is, say, 60db down then when you add it to the louder value you are only getting 84db signal to noise on the smaller value, That would be 60dB down on the larger value or course, going to have to add a fair few of those ...

Dan, if you don't make Synth Fest I will find you and I will wedgie you.

I didn't think Synth Fest rolled around until October?

Regards, Dan.

You say that but I spent a whole day yesterday working out the phase responses of varying eqs (including linear phase) and it was a real head turner. For that sort of thing was Matlab/Scilab/Octave invented, no need to do it on graph paper any more. I cannot see much point in calculating the phase ...

Typo, good catch!

For FP it is in the 'don't worry about it' region, most DAWs set things up so that 0dBFS is +- 1.0 floating point, and the maximum representable IEEE 754 floating point value is > 10^38, so headroom for days. For any integer format (8,16,24 bit) the broadband noise floor is at (-6.2 * Number of bits ...

Not al all sure I buy the basic premise... Sure, a biquad is a biquad (but only if you maintain sufficient precision in the arithmetic, which is not at all a given, and only if you get things like the warping for the Z transform correct, in extreme cases oversampling to get away from the asymptotic ...

It is more complicated then that! For example, I will have a spec to design to, noise, distortion, frequency response, form factor, price point, delivery date..... Now if the measurements fail to meet any of those, I have a problem, and if the thing fails to sound right I have a problem, and if it ...
