Did they decide to make audio and video optical formats play from the inside outwards? Was it simply due to the idea of making variable sized discs? IE if you look at, for example early copies of James Last Tango, or Roxy Music Avalon you see that there is a huge part of the surface not used and it can be used as a mirror. Perhaps back in the day, it was thought that one could crop off the...

This is just to update people wrt my old "Scots Guide to Electronics" website which does contain some audio related material. The Uni has recently made some changes to their website and an 'old' version of the address no longer works. Their used to be two top level URLs, but now only the 'full name' version works which is now. https://www.st-andrews.ac.uk/~www_pa/Scots_Guide/intro/electron.htm

I've continued to think about ways to reduce the excess 'sea of noise bits' that tend to occuply the least significant bits per sample of 'high rez' streams and files. These tend to bloat FLACing, etc, so waste space, money, time, etc. Occurred to me that Noise Shaping down the sample size whilst keeping the high sample rate might help. So I did some simple experiments. If anyone is interested...

Just been listening to the Brahms German Requiem live from the Chapel of King's College Cambridge. I have to say that I am not a particular lover of Brahms and even less of his Requiem, but having been a resident of Cambridge years ago and been to many concerts and choral evensongs in that Chapel I have to say the sound was stunning - so real and clear, you could almost have been there. Ah...

Does anyone have a favourite recording, or good demonstration, of imaging? The sort of thing where you pick out an individual instrument and get an accurate sense of where the musician is relative to anything else that's going on? -- Cheers, Rob

I was on my way to a studio in Stockholm. The owner told me had a "classic British sound" I was interested to find out what he meant. Acccess to the control roon was via the studio. In addition to a good selection of new and vintage German mics, and a fine model B Bluthner grand piano, I noticed a number of Reslo ribbon mics, and a Premier drum kit. Was that what he meant by the "classic...

It has recently been announced that the EUBO (The European Union Baroque Orchestra) will relocate from Woodstock, Oxfordshire UK to Amsterdam. That's sad. The British do not have the strong symphonic tradition of some other Western countries, but we *do* have some of the world's finest baroque composers: Thomas Arne, Henry Purcel, Orlando Gibbons, William Byrd, and of course

Pleased to report that the ukhhsoc public website is now being produced. The society currently has a collection of thousands of files relating to various hifi products, makers, etc. So far as possible within limitations of copyright the aim is to make these openly available via a web archive. http://www.torrens.org.uk/ukhhsoc/AudioDocs.html The above page is the address which people can use...

Hi, Has anyone else encountered this odd effect. Listening to a flac file of a jazz piano trio with the drums on the right. Suddenly the drums are on the left, then a few seconds later they are back on the right. The player is a Raspberry Pi with HiFiBerry DAC + Pro. There is nothing wrong with the file which plays ok on the Mac

I have almost cured this using a high quality powered 7 way usb hub. Very chunky psu and hub is made from very solid alluminium. Now the remainder of the issue seems to be earthing and position of cables related. Thus most of this crud was coming up the supply line obviously, the culpriit seems also to be the SSD made by Samsung in the computer. Brian -- ----- -

I have been using a pair of Yamaha MS 101-III as nearfield active monitors for a couple of days, while selecting material for an editing session. These speakers have a 20 year pedigree (MS 101-I), They are small, inexpensive (Euro 270 a pair) and sound rather good. Take a listen

So its like this, when we record sound onto a computer its adjustable and set to be correct, but when we play it back it is quieter, even though its actually the right level according to Goldwave or any other editor or recorder. The real issue is the mix level it seems when recording. Monitor levels internally in the card/sound interface seem always to be pre set too high compared with the...

I was looking to find a simple answer to this issue, which seems to afflict any usb sound device I use to connect to an analogue source. I did try the internal card also, but that suffers from swooshes and other weird noises due to it being inside a busy computer one assumes. In the majority of cases the while is constant, though can vary if other things are going on in the machine. it...

During the early1970's the major UK record companies decided that mono LPs would be discontinued. However there was still a very large back catalogue in mono - fine recordings of excellent performances - for which there was still a considerable demand. There had been many efforts to produce "electronic stereo" by means of EQ and pan pots in an attempt to "separate"

Anyone know of the simplest way to provide phantom power (the usual 48v) to a mic amp that currently doesn't have it? Obviously, an external plug in supply is one way, but wondered if there was an IC or whatever that would produce it from the mic amp's existing PS, which is a discrete +/-15v type. -- *What happens if you get scared half to death twice? * Dave Plowman ...

You know increasingly I'm noting that the young uns seem to be listening to all their music on crap gear. IE many of the sound systems for multi room use are 1 mono speaker or one speaker with s speakers facing different ways. Look at the amazon Echo, or the output form I phones etc. Its time for a stereo or surround revival quite obviously, and sadly it is starting but only in virtual...
