The kickbutt streamer of tomorrow

…or my definition, anyway.

I ask myself, if I could call one of these fine companies tomorrow morning or perhaps just after the weekend, and have them build a streamer perfectly fitting my needs – what would it look like? The streamer, that is. Well, here is a list of the features that really are ridiculously cool:

  • First of all it should be able to rip from CDs, store them in a lossless format, preferably Flac, replay them an stream them to other clients.
  • It must be able to use off-device storage, such as a NAS.
  • It must recognize uPNP devices on the network and itself be one.
  • Tracks and playlists should be manageable from a web browser.
  • Analogue input, like the Arcam or the Colorado vNet.
  • A nice sized display and not relying on a TV or computer monitor; not saying that it shouldn’t support one. The display equipped remotes like that of the Sonos are wonderful.
  • Digital output. The thought of putting a Benchmark or Bel Canto on the end of it is almost making me weep.

There are a couple of things, I haven’t seen yet. One thing that springs to mind, is realtime conversion. Consider this: You have a neat little MP3 player and you have a whopping music server, serving Flac right and left. See the problem? You want to go for a jog around the neighbourhood with the latest Brett Anderson recording from B&W Music Club soothing your ears, only the server persists on shoving Flac down the throat of your measly Zune. If you could connect your MP3 player to the server and have it save a playlist as downsampled MP3 to a USB device – there wouldn’t be a dry eye in our household.

I would like to see statistics. Which files were played when. I would like to see it scrobble to last.fm. I would like to see it stream from last.fm. I would like to see support for private streams – streams that require a user to log in.

Lossless music; even if I am a copy cat

bwmusic Bowers & Wilkins, or as they are more likely known to most, B&W, have started a music club partnering with none other than Peter Gabriel and his Real World Records. The idea is to offer music in lossless compression to those [of us] who twitch over the MP3 downloads that are so popular. Bandwidth is soaring and disk space googolic  – let us have music in its pure form and not in a tin can. We can take it!

Every month a new album will be published for download in Apple Lossless or Flac, ready to be put to CD or thrown straight at your media streamer; all at a yearly subscription rate equalling roughly a mere 5 or 6 CD albums. So, if you like being subjected to something new once in a while, this is cheap whichever way you look at it; and bloody good quality to boot. Last month featured Little Axe – this month Grindhouse (mondo cane) and the next is Gwyneth Herbert. A truly varied selection.

Oh – the copy cat thing? Super cool blog spot Download Squad posted this this morning.

Did I say lossless compression enough? Take a look at the cover art you get with most download services. If it is even there it is usually restricted to a measly thumbnail of the cover. Even that is lossless in B&W’s club… you can download an actual booklet or insert with every CD. Printing it can be a bit of a challenge, though. But that is hardly their fault. No, this is going to be very, very nice.

Thumbs up! And let us have some copy cats already!

You scream, ice cream, uPnP media stream

Most of these streamers have uPnP support and it occurred to me today how important that really is. One of my two streamers does not support uPnP but it does support scanning a network location itself. That should suffice, one would think. But the problem is that our music server stores more than a thousand albums and scanning it every time there has been an addition takes a very long time [I am being very diplomatic here]. Our uPnP server on the other hand does this in the background and keeps the list of music up to date. Clients get immediate response upon a request.

The general setup is this: We have a workshop where we spend much time. We bring CDs from the living room and play them there using a PC based media center. The PC automatically rips CDs to the network when it plays them the first time. From there on we can stream the songs from either the workshop where we ripped them or from anywhere else in the house where we have a media streamer or a computer. The setup we are looking for is one where we can rip CDs at either location and preferably control playback from a computer as well as from the media streamer. A few of the devices mentioned in this blog actually supports this. Mmhhh…

My apologies for the tacky title.

Around the boxes

I think I should mention the idea behind the blue bars and the orange boxes. Let’s take the last ones first. They have no meaning. There; I said it. They are there simply to give a quick overview of a small selection of key features.

The blue ones are slightly more meaningful but that does not mean that you should go out and buy the ones that have a blue box on the right and ignore the ones with a box on the left. They do not signify quality! In my vocabulary quality is a measure of the extent to which one’s expectations are met – and that is exactly what they are – expectations.

Let us take an example. If you go to the store and grab a Linn Klimax and put it in your kitchen to have music while you cook, you are pretty likely to be disappointed and have very little table space to chop onions. If, however, you get yourself a Freecom MusicPal, you will propably find it somewhat easier to fit with your knife rack. The first one is a far right and the latter a far left.

Flac in less words than you can [safely] swing a cat at

I do prefer Flac over other compressed audio formats. Over any audio format , in fact. A standard audio CD is encoded in PCM which is, if you like, a raw stream of digital information. MP3 and Ogg-Vorbis compress this stream by transforming the stream into something perceivably the same as the original but not quite. The higher the compression the further away from the original we get. It is actually possible to perform a surprisingly radical compression with little loss in sound quality. The problem, of course, is that someone has to decide what is perceivably the same – for most ears are different when it all comes down to it and what is worse – once you notice the difference, your perception has been forever altered. This is where the lossless compressions come to play their part. Instead of removing or altering information, the stream is compressed pretty much like a Zip file, only optimized for audio and more importantly; inherently so.

Flac supports samples resolutions of up to 32 bit. For more trivia, please visit the Flac homepage.

For those who have never tried this little experiment, this is what you should do… find a good CD in your collection, preferably one that does not have a compressed sound tapestry quality to it – you know; Phil Spector. Rip the CD to MP3 and then listen to a song in either format, one after another. If you can’t tell the difference, there is no need shopping for Flac capable equipment unless it offers you some other needful feature. If, on the other hand, you do hear a difference, you will be forever addicted to lossless encoding [*]. It should be noted, that not many people can tell the difference if you rip at a bitrate of 320Kbps and most that I know of rip at 192Kbps– so don’t be disheartened if you don’t feel the revelation just yet. But one day you will.

*I am relatively certain that you cannot sue.
