BBC Memoryshare - Jamming the Germans

BBC Memoryshare - Jamming the Germans

The 75th anniversary of BBC WS has started some very interesting recollections - including how the BBC was prepared to jam its own network in the event of a Nazi invasion of Britain.

Marantz PMD620 Digital Audio Recorder Update

Marantz PMD620 Digital Audio Recorder
Back on the 7th of OctoberJosh Bancroft

John Bancroft provided us with a shot of the new PMD620 digital audio recorder on show in the US at the Podcast and New Media expo. It takes SD or SDHC memory cards and uses 2 standard AA batteries (you can use rechargeables if you want).
It seems the Marantz PMD620 Professional Handheld Field Recorder is now retailing in the US at just a few cents under US$400. The photo may lead you to believe otherwise, but this relatively small solid-state device is only slightly larger than a deck of cards. Records either MP3 or WAV files in 16- or 24-bit rez. The display screen uses OLEDs just like many cellphones, and it has two high-quality omnidirectional condenser mics built into the top. If you don't like those, you can plug in your own external mic, albeit with a 3.5 mm jack input, not XLR (Canon). If you want to check out all the specs, there here is the owners manual.

This is obviously going to be a serious competitor to the M-audio recorder which came out last year at around the 300 Euro mark. One immediate advantage is the fact that it uses ordinary AA batteries rather than built-in rechargeable cells. I think the case is a lot more studier on the Marantz than the somewhat flimsy plastic of the M-Audio. I always seem to find that the batteries on my M-audio are empty at the moment I need the thing, especially if it has not been used for a couple of weeks.

So could this also be the end of the Marantz 670? I sincerely hope so. Everyone I meet complains about the size of the thing and that (at least early models) have problems that the software shows a dead battery when there is still life left in them. I have never met anyone who got the claimed "7 hours" out of a single charge. The PMD620 at least shows that Marantz has been thinking about the reporter in the middle of nowhere who can usually find some AA batteries before they can find a reliable electricity supply. It has an advantage over the HHB Flashmic in recording in stereo and having a removable flash card. The built-in microphone of the HHB unit though is even more compact than the PMD620, and would probably win if you're part of a press scrum trying to get a quote out of a politician. Comments?

Logging the output of 50 radio stations

What do you do if you're the BBC World Service with just over 50 feeds leaving the building at some peak periods. You log the output on hard drives from this company. Comes in models with 8, 10 or 15 Terabyte raw capacity. Those vents are indeed for cooling fans.

Seeing more and more of these headphone/close microphone combinations being used in radio studios around the world...the latest siting in BBC World Service South-Asia broadcast centre. The microphone sounds great, providing it is not put too close or knocked out of the way - it needs to "look" at the mouth it is listening to. I find the response better than Sennheiser. Not sure why the data sheet says it is preliminary. Price? About 180 pounds sterling in the UK. I use one for HD-camera work when I am interviewing someone. My questions are on track 1 with these headphones, the interviewee wears a Sennheiser wireless lapel mike recorded on Track 2.

The Sony NW-DB105 and NW-DB103 in a shop window in Buenos Aires. The only difference is the storage capacity. In Euro the 1 GB works out at 80 Euro in BA, whereas in Europe it is 39 Euro in on-line shops. I am interested to see if such a device could be used for simple recordings by community radio stations. There would be a market for a simple "push to talk to record" device.

Snowball Microphone

Let's face it, most webcams produce less than ideal sound. Loic le Meur, who is just setting up a new social software platform with video does a test here of the Snowball Microphone from the US/Latvian company of Blue. Headquartered in Westlake Village, California and with engineering and manufacturing facilities in Latvia, Blue Microphones continues to come up with cutting-edge designs. Blue is also known for its vintage microphone store and restoration services.

The Snowball USB microphone isn't all that new, but it hasn't really been discovered by the podcast community yet and it is probably the wrong shape for reporters in the field!. But it is easy to use. Just plug it in, adjust your input level and you’re up and running.

The Snowball is a condenser microphones but derives its operating voltage from the bus voltage always present on your USB port. As long as the red LED is glowing, the microphone works. The Snowball does not require batteries or phantom power.

To get the most out of the Snowball, you’ll want to have some kind of software that allows for digital signal processing and non-linear editing that will accept audio from the USB port. As long as you are using Windows XP, Vista or Apple OSX, you will not need any drivers. Not sure whether there are any compatability issues with Mac's Leopard.

The Snowball’s digital output is set to 44.1 kHz / 16-bit, just like an audio CD. The sample rate / word length are not user-definable. The mic comes with a sturdy stand and a 2 metre USB cable. The ball itself seems very sturdy. Out of the box the Snowball is set to record at low levels (fine for instrument, less fine purely for speech), but the Blue website has firmware updates that will fix that. But there is no software to control the mic reception pattern settings. This can be done manually though, using Snowball's 3-pattern switch which allows you to choose from cardioid, cardioid with -10dB pad, and omnidirectional. Cost? In the US around US$100, that around 70 Euro. In Europe, there doesn't seem to be a dealer in the Netherlands, but Thomann in Germany will ship. They charge 99 Euro for the microphone and another 8 Euro for shipping. Not often you see "Made in Latvia" on a product.

Media Professional Website Launches

I have been gradually building the website which describes the "making of" a new media lab in Porto Novo, Benin. Located in the western part of the capital city, the new website explains how we managed to build a complete FM radio station in under a day towards the end of July 2007. The idea is that the "lessons learned" will be translated into local languages so that station managers are able to profit from our experiences. It costs around 25,000 Euro to build a community station of this type. If you want more range, then prices quickly climb to 40,000 Euro. The local versions of what we did will be distributed on USB memory sticks which are rapidly replacing CD's for transporting audio files around the country. ADSL is due in Porto Novo in January 2008, but it is still relatively expensive.

EBU Audio Contributions Document

In the near future, if you're planning to buy some equipment to feed audio back to a radio or TV station, you might want to ask the manufacturer of that equipment if it is ACIP compliant. ISDN lines are disappearing in some countries (as soon as 2010 in some places) and so broadcasters are starting to use IP over broadband technology to get the audio back to the studio. Its obviously important that the equipment at both ends is compatible even if it is of a different make (just as your mobile phone works no matter who made the handset). I note that a group with the EBU Technical department has now published an interesting document in the hope that manufacturers will work on interoperability standards even if they are competitors in the marketplace. There is a publicly accessible website that's gone up as well.

So why is this important? For the punter in the field trying to do a decent reporting job, it's going to vital that this project moves from a well thought-out proposal into practice. Even if you're non-technical, if manufacturers get the message from reporters that compatability is important, that may help the development team squeeze the required cash out of the upper management.

HD Radio University

HD Radio in trouble? I agree with Lou Josephs in Washington that the take-up of HD Radio hasn't been what observers expected. Now comes news that there are all kinds of skywave inteference problems which have prevented some stations switching it on. The backers of HD Radio have opened a sort of McDonald's Hamburger University, they call it HDRadio University to try and educate sales people. That is increasingly a challenge as discount retailers don't pay that much and staff turnover is huge.

Meanwhile, the trade journal InsideRadio has reported this week that the HD Digital Radio Alliance has set aside $230 million for marketing HD Radio. The biggest change next year will be the introduction of commercials to HD-2 channels. Stations will accept "name-in-title" sponsorships and limited sponsor mentions per hour. Programmers will also get more freedom when picking a HD-2 channel's format. So what will this mean? Great, creative, vibrant programming on a second channel? Probably not - a simulcast from AM is more likely. It is not the technology, it is the programming guys!

Cox Radio has installed HD equipment on a half-dozen AMs, but millions of wideband radios installed in DaimlerChrsyler cars, Jeeps and Mercedes are keeping them from flipping the switch. The wideband radios give better sound quality, but Cox Programme Directors have complained about hearing "a faint buzzing noise" on HD AMs. Cox has installed HD on 70 stations and they'll add another AM to that list by year's end. The engineering forums are full of polarised debate on the future of digital AM, especially as the technical roll-out has started and interference problems are cropping out. How come they didn't surface during the last 10 years of "testing" IBOC on mediumwave (AM).

Remote News Bureau?

At IBC 2007, I bumped into a French company called Alden that were marketing a steerable satellite dish for people in Eastern and Southern Europe who live too far away from an ADSL hub. It is a satellite TV and satellite Internet combination. The initital outlay of around 3500 Euro involves the purchase of a self-aligning dish and 100 days of Internet access (any 100 days within a year, no limit of the day during the day). For people who are never going to get connected to cable and/or ADSL, a rather neat solution.

Vidblaster Pro

Get past the intro of the Kats Cast to see excellent camera work at the Uitmarkt in Amsterdam and what "Mike" (Versteeg) is up to with a Vidblaster Pro. The price of this software is amazingly low - just under 78 Euro. Certainly made for love, not the money. No commercial connection with these guys...just admire what they have done.

MyDrive Music Disk

Perhaps because my original work was in radio, I tend to pay more attention to music and dialogue in video than most video editors I know. I have collected production music for years. I note that the racks of CDs in many video studios though are disappearing - partly because they are a magnet for dust.

A few weeks back I saw an ad in BBC's Ariel magazine advertising a (free) harddrive full of music. At the moment, in Europe, it only available in the UK. JW Media Music Ltd tell me they have explored various means of getting music to clients. They offer Internet downloads and have released larger itunes based hard drives in the past; both as attempts to cut down the waste produced by sending out so many CD's.

Although these endeavors have both been received well by clients, the MyDrive has been the most universally accessible format to date. The software (originally created by an Australian library we represent in the UK, Beatbox Music) offers a really straight forward search interface. You just plug it into a Mac, PC or Avid using the USB port and there are 10,000 tracks from five top music libraries waiting to be explored.

Having auditioned the tracks you want to use, simply hit export and save the file to your computer as you would a word document. All the music rights (MCPS) registration details are saved on both the track name and the MP3 meta data, so no need for post-it notes all over the place as with CD's.

Also featuring on MyDrive in the UK are Beatbox, Standard Music, Noise Pump, and LA Post. Although some other publishers have experimented with the idea, it is a device which has so far not been matched by any other UK Libraries. JW Media say they have over 500 in circulation at present in the UK alone, with more and more requests from editors, producers and sound engineers coming in everyday. The device is free, as the music contained within it is all set rate, MCPS administered music which the user pays for either directly to the MCPS or through their broadcasters blanket license (such is the case for the BBC).

I believe it is important that if music publishers want to get producers to log the right content details, they provide a device like this to manage the metadata. In the past, I have seen so many producers either get things wrong or make things up because they didn't regard the admin as part of their production task. And since this can be automated, I agree with them.

Mayah Sporty Codec Update

Saw this new version of Mayah's codec for in the field reporting at IBC 2007. In an earlier post I said I thought the price would be near 4000 Euro including tax. But Uwe Flatter from Mayah Germany reports that it will be 3350, with an introductory price of 2450 Euro for orders before November 15th. 900 Euro is indeed a huge discount.

I am not sure how long ISDN lines will be around in some countries. Some PTT's seem to want to get rid of ISDN as soon as possible - I believe Sweden is talking aboout phasing it out in 2011. Other countries, like Swizterland and Spain for instance - they have discovered quite a few customers using ISDN and have no immediate plans to migrate them. What I am finding in Spain and the US is that local operators are getting reluctant to organise ad-hoc ISDN connections and start charging a lot of money for the service.

Completely Blocked in China

It would seem my comments on this, and other blogs, about firewalls in China and some problems I see ahead for the Olympic Games in 2008 (the really hot weather) have meant that all the websites I operate cannot be accessed from inside China. Firewalled but surviving! At least they are consistent. Look at the stuff 1.2 billion people are missing ;-)
