I'm currently working though old issues of "Hi Fi News" building an index. Came across a timely snippet. 17th April 1966 was when the BBC boadcast their first 'live' concert in *stereo* as part of the normal schedules. It was during the afternoon, and timed to be during the Hi Fi Show that was running at the time. This was a 'bonus' as they also had a low power TX running during the show,...

I have been trying to make my new computer integrate with my stereo system. However even using a Behringer usb sound interface still produces a whine and general hash low level to playback signals, though not noticed on the recording if its transferred to cd and played normally. The question is that as things are plugged into the usb the tone and loudness varies, so I suspect its either the...

I'm not a fan of 'forums' but given the impression that few people now use newsgroups or indeed email lists I'm wondering if it is worth trying one that is UK focussed and aimed at audio / Hi Fi. Hoping to get more info for things like tracking down the documents / info I seek these days. Someone has suggested the 'Pink Fish' forum. It does seem to have a UK feel, and is apparently moderated....

Thought I'd raise this here in case someone can help. I've continued to do background research on the history of Armstrong Audio / Wireless in particular, but also other UK makes, etc in general. Since the start of 2016 I've mainly been trawling pre-1960 issues of magazines, back to the 1930 and collating what I'm finding. However there are two things from the 1970s which I haven't been able...

Hi - I originally posted this in uk.comp.sys.mac and was recommended to try here as well. Does anyone know if there's a utility to get average decibels from an audio track, where 'an audio track' could mean wav, aif, mp3, or mp4 (as in I'd convert to whatever's necessary)? Context: am trying to prepare a number of different music tracks to be at the same level. It's my music so I have...

I've taken the cover off, and noticed the battery seems to be leaking slightly: https://flic.kr/p/EdXFsh There's a white furry deposit around what I assume to be the battery - the blue thing centre top. The underside of the circuit board looks fine. Is a replacement straightforward? I can solder after a fashion.

Just to let people know I've put up a new webpage at http://www.audiomisc.co.uk/Armstrong/reviews/silicon/EarlySiliconEra.html This documents the 1973-4 period when they released the 600 range and it got a lot of attention. Can be interesting to compare reviews to see when they agree and when they conflict. :-) FWIW I'm planning two more pages.

I have noticed fewer Medium wave stations as per a previous thread, but not on Long wave. Indeed the Irish station is beating with a French language station. Sounds like bloody minded ness, as there would be room for one of them to move it seems. Brian -- ----- - This newsgroup posting comes to you directly from... The Sofa of Brian Gaff...

Would you suggest running this every so often to keep it going or just store it away in an even temp dry place? Old Rogers valve amp, JvC graphic equaliser old cassette deck etc. Brian -- ----- - This newsgroup posting comes to you directly from... The Sofa of Brian Gaff...

High speed mono cassette copiers? We have a lot to dump and it seems a shame to do this, but nobody seems to need to copy audio cassettes any more. These are Sony ones several slaves and a master the slaves have four bays the master has three all cables are there though longer mains cables might be needed but are the same as computers use. We also have a set of four stereo copiers as well...

Is this thing on? Seems my posts to this newsgroup are being eaten. Brian -- ----- - This newsgroup posting comes to you directly from... The Sofa of Brian Gaff... Blind user, so no pictures please!

OK I have a not that old but out of warranty Marantz cd player which is supposed to and did play cdrw disc. However over a time its stopped doing this and now has issues on some, mainly home made but some commercial, discs as well. This manifests itself as hunting either at the start or when you manually move a track u the listing. It hunts for a couple of seconds then gives up with an...

Sorry but I sent a question here yesterday, but not seen it yet. Brian -- ----- - This newsgroup posting comes to you directly from... The Sofa of Brian Gaff... Blind user, so no pictures please!

I was looking around various sites for some relatively cheap speakers for my bedroom that do not sound like cardboard boxes, and are not of the younguns megabase as used by DJ Plonker etc, and the name Beng came up. It only seems to have outlets via Amazon, and the reviews on there should I feel be taken with a pinch of salt. they say the packaging was rubbish resulting in damaged cabinets...

I've recently been writing a program to 'probe' HDMI monitors or screens to see what audio modes they accept. The results have prompted me to wonder about their limits. I've only seen results from a few. But all the ones I've got data on only work for LPCM sample rates up to 48k max. Which would leave 'high rez' audio out in the cold. (And when sent 44.1k the seem to dumbly resample it 48k upon...

This must have been discussed before but I'm wondering what people here are using these days. I've sort of managed with the Microsoft WMP offering until now but I'm sure there are better library managers around. Advice for me to generate a short list would be appreciated. I'm probably going to be looking at MediaMonkey and Foobar2000 which happen to be freebies. Any others I should check?...

Common way to stop the thump you can tend to get with a MOSFET amp at switch on was a relay on the speaker output. It occurred to me that in these days of cheap high power triacs it might be better to ramp up the AC into the amp - even if it uses a conventional power supply? Comments welcome. ;-) --

Need some well screened co-ax 'phono' cable. A quick look at CPC shows only the usual lapped screen variety. Which I already have. Basically, I need to run an unbalanced circuit close to some mains lighting wiring which has a dimmer. And the stuff I have is letting in buzz. Tried some RG 59 I have lying around which eliminates the buzz - but I don't have enough and would prefer a more flexible...
