Philips Fidelio X1/00 – Review

So I went out and bought the Philips X1 headphone. It’s expensive. It comes in a HUGE box, the unboxing experience is nice, although it’s kind of hard to get the cable out. I plugged the cable into my tube headphone preamp, put in the SACD remastered version of “Kind of Blue” by Miles Davis and hit Play.

kind_of_blue

Wow!

Wow!

This isn’t the fastest headphone, it doesn’t have the “air” or agility of AKG 702s or Sennheiser HD 700 let alone HD 800, but: This headphone is FUN! I started listening when I was tired, it was 11pm and I was ready to go to bed. But an hour and a half later I was still popping in disc after disc and listening, dancing, playing air guitar, and smiling, smiling. This headphone made listening to music so enjoyable. I didn’t even realise that my girlfriend woke up and went to the toilet while I was playing monster riffs on my air guitar… Slightly embarassing that one, ha!

One word about comfort: Superb! The earpieces are from a material that feels very comfortable, they don’t press your head, the headband is also very comfy. I stopped noticing that I was wearing them after 15 minutes.

So for those purists, technophiles and spec-sheet lovers: Go and shell out 900€ for the Sennheiser HD800. For those that want to have fun: buy the Philips. It’s that good, you’ll love it!

in search of the ultimate headphone – update

My search for the perfect headphone continued with me buying Shure SRH 840s.

These are great everyday headphones, workhorses. Easy to wear, not fatiguing, comfortable, come with a nice carrying pouch, and are really affordable (100€). But, they’re not great. So I kept searching, listening to stuff like Chambers by RZA, HD 700 by Sennheiser, and just 3 days ago stumbled upon Philips X1/00 Fidelio.

Wow! Like AKG 702 with bass. I never would have expected this from Philips! On second thought: I have 15€ earbuds from Philips that I really love to listen to, so it seems like the folks there know what they’re doing.

I ordered them a couple of days ago and will let you know how they do.

My vision for mobile computing – 2015

I’ve been carrying around a vision of where mobile computing could go in the next couple of years.

3 trends shape that vision:

  • mobile devices are increasingly location aware – geospatial big data.
  • more and more of our activities are organized, shared and conducted online.
  • economic development suggests fewer full jobs – the rise of the enrepreneur.

Let me explain:

  • Nearly every smartphone and tablet has GPS built in and location enabled, knowing where exactly it is on the planet. Even devices that have location turned of can be triangulated with devices WiFi MACs. (see here).
  • Selling, buying, creating, sharing our activities. Instagram, oDesk, Facebook, twitter… More and more of our activities are either conducted online or shared online. With sufficient analytic power incredibly detailed profiles of your skills, interests, and desires can and are formed.
  • The current demise of the US as the world’s number one economic power, alongside Eurozone depression and growing economic uncertainty will lead to massive cut-backs in state spending, in my opinion. Even if, out of political convenience or percieved necessity, nations continue spending, that would lead to huge debt write-offs later on. What that means to me is: fewer full jobs, as companies become increasingly reluctant to pay the high overhead associated with traditional staffing, combined with the relative ease of online hire-and-fire on sites like oDesk and others. This will greatly entice the population to become more and more self-sufficient, start small businesses and become entrepreneurial in the truest sense of the word.

And here is where my vision comes in:

What if you had a tool that would give you superpowers?

What if you had a tool that would help you to see the world around you in new ways meaningful for your business?

Would you use that?

 

Okay, here is how it works:

For a second put all privacy concerns aside. These matters can be addressed with amazing inventions like homomorphic encryption  and privacy-by-design.

Imagine an app that analyzes all your browsing, facebooking, online shopping, and online working, blogging, submitting-for-review and so on.

Let’s say as Phase one, the app would see you’re looking for chairs on ebay and craigslist.

As you walk home, your smart device beeps, and you’re informed, that in the house to your left, somebody sells a chair that’s compatible with your taste, is within your price range, and that person is at home.

With the touch of a button you’re on the phone and within 3 minutes have seen the chair, liked it and brought it home.

Or: you’re a programmer, and do some java and website work. You have some capacity and indicated so in various emails. While standing in the subway on your way home, the person next to you hears her device beep, she’s currently looking for somebody to do her website for the little bake-shop she started. She looks at your profile, likes it, and decides to talk to you. 2 stops later you have a job, and 3 days later she has a great website.

 

Phase two: The application gets smarter. Cognitive computing and context accumulation enable it to find out what you do, what you like to do and what you’re good at. Relevant jobs and people find you as the application suggests connections that you would have never dreamed about.

 

For me, that’s were mobile computing should be headed. It should make it easier and more attractive for us to start communicating, to start doing business together. In person, right here, physically. That’s the promise telecommunication technology has made and so far never delivered. Instead it has isolated us, mediated our communication, made us more indirect and less approachable than ever. This can change.

Let me know what you think…

Oh and if you’re a programmed or a VC and want to start developing this, I’m all in.

The wounded child – misunderstandings about

Although I set this up and edit this blog as very tech-centered and tech-related, from time to time I feel moved to write something about life, our perceptions or our attitudes.

This blog post is one example.

For some time now there has been a lot of talk, especially in psychological, spiritual and self-help circles about the wounded child. The wounded child refers to the part in us, that did not get its need met in childhood, when we were dependent upon others to fulfill them, in a timely and judicious fashion, and so remains stuck at some level of development, often recreating the dysfunctional dynamics later in life.

It’s unanimously agreed that we repeat these patterns so we can grow concious of our past hurt and then move on, thereby healing ourselves and the dynamics, that otherwise get passed down from generation to generation in a family.

Often, the dynamics are seen as logical conclusions, patterns of behaviour that the child had to adopt in order to survive in a dysfunctional family.

Here is where I disagree. Yes, most of us did not – at some point in their childhoods – get their needs met. Yes, many of us had experiences with shameful /shaming mothers or fathers, critiquing parents or simple neglect, in one form or another.

But: the behaviour the child then established is its own choice, it had many options and it chose that one. Now you might say: Yes, but had the parents recognized this, they could have educated the child. Since we assumed that the beaviour was the response to some kind of neglect / critique or shaming, it is safe to assume that the responsible parent did not do so from the consious, self-reflected and loving part in itself and therefore will have a hard time assessing the behaviour as a response.

My point is: today we underestimate how willful, resourceful and active / present children are. My point is not to condone neglect, but for ourselves to see that we were the architects of our behaviour from day one on. Then it becomes easier to own up, and move on, and not get sucked into a circle of victimhood, and bleeding-heart storyline.

 

 

Why High Definition digital audio matters

Today I found a very well-researched, well written article on xiph.org, that basically said that 16/44.1k should be enough for everybody.

I was slightly irritated, because I’m a firm advocate of DSD and 24/96k; having heard, and been able to spot the differences many times.

The author, Monty, argued that the human hear is unable to hear frequencies above 20k.

He cited the usual, well known studies on the subject, and was kind enough to include how they arrived at their conclusion.

And here is what he got wrong: The studies, upon close and unmerciful inspection, show only that the human ear is incapable of hearing sinus waves above 20k. Well, I’m not going to argue with that, we’re not bats, spot on!

If you know how a Fourier Transform works than you probably already know where I’m going here,  but if not, read on:

Any waveform, says Fourier, can be divided into sine and cosine waves of different frequencies, that combined yield the analysed waveform.

A square wave of 10k would have a 10k sine basic and then a 20k sine on top of that, and a 40k and so on, until it becomes a square wave.

Now if you chop off the frequency band at 20k, it just doesn’t look anything like a square wave, and doesn’t sound like one either.

But square waves are about as common in nature as sine waves, so that isn’t much of an argument in the favor of 96k sampling.

But, … transients: sharp, short spikes of audio, happen very often in nature and in music, particularly in modern music. And here 44.1k adds severe distortion, making placid hills out of sharp spikes, while also adding pre- and post ring to the spike, courtesy of oversampling digital anti-aliasing filters.

Now Monty goes on and cites a study by the AES that revealed candidates were only guessing whether something was 96k or 44k in an ABX blind test.

Why? Hard to tell, but reproduction equipment could be the main culprit here. Cheap amplifiers, headphones and loudspeakers often have very poor time-domain fidelity. Meaning? They smear a short, sharp transient all over the place. Making a better time-domain resolution undetectable.

David Blackmer, the eminent founder of DBX, wrote an excellent article on the subject in 1999. Here is a link.

To sum it all up: We need high-def digital, but we also need to focus more on time-domain fidelity. Here’s were the audio equipment industry is not delivering today, mainly because nobody cares. You get a pair of pretty flat frequency response headphones fo 5$, but headphones with great time-domain reproduction are hard to find and expensive.

For loudspeakers Meyer Sounds HD-1 come to mind, at 7000€ a pair…

Happy listening.

 

Hearing in a relative world – perception bias

I’ve been reflecting on the process of hearing, a lot, lately, and most of all about how we hear  frequency response. When do we percieve a song or a mix to be flat spectrum, when do we think a song is “phat” and when is it just bass-heavy?

I think the human brain strives towards presenting perfection to it’s user. We all know, that when listening to a strange sounding mix, it can become more agreeable over time, and sometimes the new sound then is our new frame of reference.

I think we can use that. If I want to make a track “phat”, I actually make it quite light on bass frequencies and then have very few elements that break that rule. For example let’s say I have a piano, some percussion loops and a kick drum and bass. I could make everything quite bass-light, except the kick, and some bass notes.

The ear adjust its response to the bass-light rest as “normal” and then gets surprised by the onslaught of the heavy kick-drum. Thus percieving the track as “phat”. Although it’s actually not.

Conversely, if I make too many elements “phat” in listening solo, I now have a bass-heavy track, and the brain “deletes” the extra bass information in presenting the track to me and so I percieve it as wobbly and not-phat.

I think fascinating mixes are all about building expectations, sonically, dynamically and structurally, and then breaking them in interessting ways.

Jazzfest Vienna, Staatsoper and Fernwärme

No started working at the Jazzfest Vienna this year. First was a Gig for 5k+ people at the Fernwärme Wien, Viennas main waste incineration plant that produces heat for over 200,000 households. You can see pictures of the enormous waste-storage cavern below. That was pretty spooky.

The stage location there was terrible, with one of the PA wings directly facing a massive steel and concrete wall just some 22m away, while the other PA wing adresses all of the 58m of audience basically alone.

I made use of the asymmetry in my PA design, aiming one side of the flown 8 MILOs just at the first 20m. The other side went the whole nine yards, with delay reinforcement of 6 M’elody after 25m. Much too short, but I wasn’t allowed any input into the stage and dealy tower planning, so I had to make the best out of a given situation. Still, the delay towers after 25m and just 4m high meant some rather bumpy coverage.

What went well was setting subs (2 times 4 700 HP) up in end-fired long-throw mode, that really fit very very well to the long-drawn narrow shape of the audience.

The people started coming in to see Viennese Soul/Funk superband Count Basic, who played at 36°C with 80% humidity and sunlight directly into their faces. The stage got so hot, that lead vocalist Kelly Sae’s UM1P monitors shut down due to thermal overheating! The audience gathered in the shadow, populating a long and narrow strip, on the opposite side of the far-facing PA (duh!).

Now we are at the Vienna Staatsoper, one of the most famous opera houses in the world. I do monitors here, with Ronald Matky of Vienna Sound doing PA and FOH. PA here evolved during the last years. We’re extremely happy with a setup of 2 MSL4s with one 700HP per side for floor and first 2 balconies and 6 M’elodie per side for the upper 4 balconies. A MeyerSound Galileo controls everything,one PM5D for Mon and one for FOH. If the PA seems a little petite, please remember that we are in an opera house with supreme natural acoustics!

I love working in this building, which consists of an intricate maze of hallways and rooms, with a stage behind the stage that is some 30m high, and can be hydraulically lowered up to 20m deep! It really is a very special place. See some pics below and keep tuned for updates.

donauinselfest 2012 – FM4 Stage – tech

Last weekend I did system tech for the FM4 Stage at the Donauinselfest in Vienna. For those of you, who don’t know about it, the Donaunselfest is one of Europe’s largest music festivals. It’s hosted on an Island in the Danube river in Vienna, lasts 3 days in June and attracts close to 2 million visitors each year.

The FM4 Stage is hosted by Austria’s most prominent independent-music radio FM4 and can accomodate close to 22,000 people if packed to the max. Acts this year included appearances by german hip-hop shooting star Marsimoto (he destroyed one M’elodie NF by kicking it off stage!), Samy Deluxe as well as austrian band Ja! Panik and a gig by the venerable Stereo MCs.

That gig got officially canceled by the authorities, but we let them play anyway, for 10 hot minutes, until the threats from the Viennese government got too severe… ha!

I did system tech, like I mentioned, working for Austrian PA rental company Vienna Sound. The PA System consisted of 2x 8 MILO speakers by Meyer Sound plus 10 700 HP and a total of 12 M’elodie as Nearfill (2), Outfill (2×3) and Center (4).

Monitoring was all Meyer Sound with 12 UM1P, 2 UM1C, 2 UPA, 2 PSW2s as Drumfill-Sub. I personally think the PSW2s really suck, since they always clip, even if just moderately confronted with Kickdrums. Unless you cut out all the sub-information, which is okay, since the PA subs were located under the front of the stage and clearly felt on top.

2x 8 MILO were enough for the natural arena in which the stage is located, but I could have used 2 more per side, budget wouldn’t allow it though. The entire PA was controlled by MeyerSounds excellent Galileo 616, I just love those filters!

I arrayed the 700s in an end-fired variety with 2×4 doing an end-fired subwoofer array for FOH sub pleasure, which most of the engineers appreciated, especially Samy Deluxe’s wonderful Tony Robbins, whose birthday coincided with the gig! The other 2 were there to spread the love around. But still, for a stage of that size 10 are a fraction too little and I had to neglect the outer areas of the arena, in favor of FOH and center. Especially those first 10m got maybe a little too much bass-love. But they were dancing all right!

What worked very well was to have a center cluster that was fed by a send of its own off of the PM5D at FOH. Most engineers followed my suggestion to just put the vocals in there.

I then summed this mix into the near and outfills and had great vocal intelligibility even in the first rows. This one’s a definite keeper.

The team was: Raimund Bretterbauer on Monitor System and Stage, Me as FOH Systech and planning the PA setup.

Below some pics. If you have any questions feel free to post here or write me.

 

 

 

 

 

 

tapestry work – beyond the portfolio

There’s been a lot of talk about “portfolio work” in recent years. Meaning that more and more people don’t hold on to a steady job, or have one singular carrer path, but instead have multiple work and revenue streams that they connect to make their livelyhood.

The term portfolio however, implies for me a certain thought-out-ness, a sense of willful diversification and planned broadening of singular points-of-focus.

In my life, at the moment, I pursue various projects,  don’t really count, but I estimate there are 6-8 active projects, and another 4-5 in the pipeline.

Some of these projects interrelate and create synergy, others are completely seperate and just for the sake of it.

I like it that way! I’m not in the game to be the best, richest, most succesful anything. I’m in it for the full width and depth of experiences available.

So I found an analogy that suits my lifestyle, and those of people similar to me, better than portfolio work: tapestry work.

My threads are my projects, my jobs, my family, my lovers, my children, my prayers, my hopes, my fears, my practice. They interweave and crisscross and form something unique and dazzling: my life!

And what a beautiful tapestry it is!

my shoebox NAS – update

So I installed Windows 8 as an OS, the Consumer Preview, to be exact.

I’ll update it to an RC as soon as one becomes available. The installations was a breeze, and I haven’t looked back ever since. Setting up an FTP-Server was easy and hassle-free thanks to FileZilla Server, Media Player does UPnP Streaming and Filesharing is deliciously easy thanks to Win7 Homegroups.
Administration is beautiful and comfy with a Remote Desktop Connection, and hey, it even displays the gorgeous new Metro interface.
SoI’m quite happy about my OS choice.
Since I didn’t install a fan – yet – and my NAS is made out of paper, I’m slightly worried about combustion. But so far in-the-box temeperature hasn’t risen above 45° Celcius, way too low to burn paper (232 °C).

But I’m going to get a fan anyway.
