Plex: XBMC-style replay facilities made easy
Plus a (literally) brilliant idea you can help support
This week we return to business as usual after my short break in Ireland, with two rather special releases from the
Furtwängler archive, in new transfers by Mark Obert-Thorn and myself.
Mark has been hard at work with two live
Beethoven recordings, made with the Berlin Philharmonic in 1952 and 1953. The earlier recording is an orchestral arrangement of the
Große Fuge, a work of which Furtwängler stated:
"Experience has shown that the monumental character of the ... fugue is brought out more effectively by a full string orchestra than by a string quartet", and one of only two performances by Furtwängler to be recorded and issued (a third is understood to exist in private hands).
This is coupled with his 1953 recording of the
Violin Concerto with
Wolfgang Schneiderhan, a performance which has been rather overlooked, especially by comparison with the three Menuhin recordings and the wartime Rohn broadcast, and one which The Gramophone's reviewer in 1963 characterised as ultimately Furtwãngler's performance rather than Schneiderhan's.
As usual Mark has found the very best pressings to work from, and produced particularly fine transfers of recordings which may have been quite hard to source recently outside the Far East.
I've also had the pleasure of working from excellent pressings for my transfer of the
Brahms German Requiem. Of the three recordings which survive of Furtwängler conducting this work, only the 1948 Stockholm performance is complete. Happily this too is the one preserved in the best sound quality, with disc noise a problem in a 1947 Lucerne performance that has multiple missing sections, and the 1951 Vienna recording described by John Ardoin as "murky-sounding" and lacking the opening of its 6th movement.
The 1948 recording was first issued by Unicorn Records in 1972 in collaboration with the Swedish broadcasters and the Furtwängler Society, and I was offered mint, unplayed discs of this release for the present transfer. This gave me a solid base to work from in trying to extract the best possible sound from a recording which lacks much very high treble and was perhaps a little light in the bass, but was otherwise quite capable of delivering more than acceptable results with some XR-style assistance. I think it's fair to say that this remastering has helped to deliver what is without doubt the best-sounding Furtwängler Brahms
Requiem issue by some considerable distance.
Two things surprised me about this recording. The first was its length: as usual I re-pitched it to A440 standard concert pitch to begin XR re-equalisation. Given that the Requiem is usually an easy CD fit I didn't anticipate any problem here - Mengelberg gets through it in under 66 minutes, whilst Toscanini, including radio announcements and extensive applause, still comes in around 72 minutes. But here I was suddenly looking at nearly 85 minutes in total - almost 20 minutes longer than Mengelberg!
I needed to get this below 80 minutes, preferably around 3-4 seconds below to be accommodated on the majority of 80-minute CD-R discs which actually run to about 79:58. This was not going to be achieved by simply re-pitching, despite a careful analysis of the electric hum components indicating a performance pitch of around 447Hz, which would at least speed it up a little. The only other way to trim was to look at the pauses between movements, where the Swedish audience got to clear their airways (to some considerable extent!). Cutting bronchial exertions alone brought me much, much closer to where I needed to be; thereafter it was careful trimming of tenths of seconds between movements to preserve the musicality of the performance - I didn't want it to sound rushed - whilst squeaking everything in under that time barrier. You'll see from our listings that I made it to 79:58 on the CD player's readout - with my own total timing coming in at a tenth of a second under 79:57. Suffice to say it was a very close call - but the performance has not been compromised, nor has it been necessary to split it over two CDs.
The second surprise came with the very last note! The organ part is given in the score but also marked "
ad lib." For the final long chord at the end of the work Brahms leaves nothing for the organ - but the Stockholm organist had other ideas, opening up his longest pipes for one of the lowest F naturals you'll ever hear on a recording of this era - or rather, "feel" - if your loudspeakers go low enough that is! Watch out for rattling windows at the end!
Playing digital audio the "easy" way: PlexI've long sung the praises of XBMC, the cross-platform free music and video replay system which we use as the centrepiece of all our domestic media consumption. It's a big, powerful system which seems capable of playing just about anything and everything thrown at it, and it's under constant development, with a major new update (v. 12.0) extremely imminent.
However, as some of you have found, it's not the easiest software to get to grips with. There's something of a learning curve, and one sometimes senses it's been made by geeks, for geeks.
Well, three or four years ago, some of those geeks decided there needed to be a better and more easily accessible way for the underlying strength of the XBMC platform to be developed. The idea was to semi-commercialise it and make it a lot more user-friendly in the process, and
the result was Plex, initially developed mainly for the Apple Mac community, but these days far more widely available, on many platforms.
I say semi-commercial. Most of what you need from Plex is free. What they do charge for is very inexpensive - a new Windows 8 app costs just $2.99 from the Windows Store, for example.
Plex requires a computer to act as a "media server". This is the PC at the heart of the operation: it catalogues your music, films, TV shows, home movies, photos and so on, and delivers them to your replay device.
The replay device may be that same computer, running Plex's replay software (which looks a bit like XBMC on Windows). Or it could be your iPad, another PC on your network, your Android phone, a MacBook in your bedroom, even (if you choose to set this up) a remote computer streaming music or video over the Internet miles while you're away from home. I believe there may also be sharing options, though I've not investigated this yet.
Setting up the media server software has been made as simple as possible by Plex. Once up and running you are asked where your music files are on your PC, where your video files are, and so on. You also set up a log-in and password for your access to Plex. It then gets to work cataloguing your files, and offers itself for connection on your wired or wi-fi network.
If you wanted, for example, to listen to your music then on an iPad, you simply download and install the Plex app from the Apple Store and start it up. It'll find the Plex media server you've just set up automatically if both are on the same wi-fi or wired network. Give it the log in and password and it'll connect, ready to stream audio (or video) from your server direct to your iPad.
Plex have also been busy working with the biggest Smart-TV manufacturers - not only will you find their apps for download at Apple and Google, but they're also ready to install on a newish Samsung or LG television, as long as it too has that vital access to your network. (Our TV has built-in w-fi - I had some success with it but the options for file formats, for video at least, seemed more limited on the TV than I'd have hoped for.)
Take a look at
the Plex website - check out the Help section for first time users, and see how you get on. It's very good, and a lot easier in first-time use than XBMC.
And if you want something to test it on...Free 24-bit compilation - 4 hours of superb music!This was first offered here last week and it a great way to put a replay solution through its paces at the highest level. You'll need to download a large file onto your computer, then unzip it - thereafter it'll be ready to play.Here's what's on the compilation:

Each recording is presented as a 24-bit 48kHz FLAC file, identical to those included in our FLAC downloads, with embedded cover artwork. Remember, these tracks are NOT CD compatible - they can only be listened to using a compatible player or software (or via DVD Audio using special writing software). The download comes as a single ZIP file which you'll need to unzip (or extract) before you can play the contents. For help on this see our online help files - and if you need more, Google is your friend!
The download is available to all our newsletter subscribers: click
here to start downloading. It's 2.26 GB in size, so it'll probably take a while to arrive, depending on your connection speed. Tracks are in alphabetical order by composer - but feel free to re-order them or pull individual tracks out as you wish.
[NB. Because of the size of the download, some hard drives formatted to FAT32 won't handle it in its unzipped state. This includes most USB keys. This is due to filesize restrictions in this almost-obsolete system which prevent the use of files over 2GB in operation. If you're having difficulties with it, do check your computer's file systems, and try saving to another drive - under Windows look for an NTFS drive.]
The time of year for giving: give the gift of light
From time to time, like any responsible business, we like to support other good causes, be they artistic or altruistic. Most of this goes unmentioned, but this week I came across an idea so simple and yet so brilliant that not only have we donated to help get it going, but I want to share it with you too.
A team of highly-regarded British engineers have been busy developing a lighting system for use in areas of the Third World in which 1.5 billion people lack electricity, and currently rely on unhealthy (and in areas of extreme poverty expensive to run, consuming 10-20% of income for
light alone) and dangerous kerosene lanterns for night-time light. I can assure you that the latter, in the total darkness of an African night, give very little illumination - but a lot of smoke: the inhalation of fumes given off by these lanterns is, for hundreds of millions of men, women and children, doing the equivalent damage to their health as smoking two packs of cigarettes a day (according to World Bank estimates).

The GravityLight is a solution to this: essentially, 3 seconds of work gives 30 minutes of power.
It's a simple idea - employing the force of gravity to lower a bag filled with soil or rocks and thus drive a highly efficient dynamo system to power a very low energy LED light. Pull on one end of a rope and the bag is lifted up. As it gradually drops down the rope passes through the light (it looks a little like a pulley system) and light is emitted. A 3-second pull to lift the weight up can provide 30 minutes of light as it descends back down. The electricity generated can also be tapped off for other uses.
Because there are no batteries, and because it's designed and built for its environment, there are no running costs once its paid for. It even comes in the bag which then holds the ballast. Currently the lamps will cost $10 each - though further development and refinements should ultimately halve this.

It's this initial development which is being "crowd-sourced" by donations from individuals and organisations online.
We've sponsored lamps to go out to three villagers in developing countries, as well as helping to finance ongoing research and development, and we will be monitoring progress with great interest.
The initial goal was to raise $55,000 - this was reached within 4 days. When I first heard about this, on Wednesday they were up to $80,000. A day later the total stood at $110,000. This is a project that's captured the imagination of a lot of people, with donations from just $10 each.
