Heavy Demand for New Freecom Beatman

Berlin, July 2001. Export demand for the new Beatman mini CD player,
the revolutionary portable MP3 mini CD player, has exceeded all
expectations, according to manufacturer, Freecom Technologies, based
in Delft, The Netherlands. By restructuring its production logistics
Freecom is able to assure European markets that Beatman supplies will
be readily available from August onwards.

In recent years Freecom has established a reputation as a leading
manufacturer of high quality multimedia storage solutions for the
computer hardware market. Its main target group to date has
been 'early adopters' who have been particularly keen on the external
CD writers in the Traveller and Portable series, now in its second
generation.

Freecom is targeting this user group to meet their demand for
innovative, practical and cost effective ways to listen to MP3 music.
The Beatman is the result of this product development and fills a
significant gap in the market for building a personal portable music
library. The surprise has been the almost immediate mass market
appeal of the Beatman that has sent demand soaring.

Peter de Waal, Product Manager for the Beatman at Freecom Europe
explains: We certainly expected Beatman to become a favourite with
the mass audience down the line, he says, but our launch to the
more specialist market has been picked up by the mass media and
generated much wider demand than we planned for initially. That's
great and we have rapidly adjusted our production schedules to take
this into account and meet demand with the minimum delay. Naturally
we are delighted by the response, adds de Waal.

The increasing availability of music on the Internet and greater
awareness and use of the MP3 format have also encouraged change in
the storage market. Now, mini CDs offer a practical alternative to
expensive MP3 memory chips and provide much higher music capacity,
storing some 850 MB of data or 210 minutes of music. MP3 music files
are simply downloaded from the internet, using the free software
provided with the Beatman. A CD rewriter is used to burn selections
on to mini CD's which can then be played anytime on the Beatman. So,
in contrast to the majority of portable MP3 players, the Beatman
offers a music lovers a chance to build and personalise a truly
portable listening library in a light an convenient format, played on
the new trend-setting Beatman mini CD player.

Comments please?  My initial take is that mini-CD players will
eclipse portable CD players, portable MP3 players, portable cassette
players, and portable MiniDisc players.

MD: copy protection on cd's

2001-07-30 Thread Matt Wall


Howdy all, no this isn't the smcs discussion any more it's something even
more evil IMHO, i'm curious about this latest trend from our favorite people
out there the RIAA

http://www.stereophile.com/shownews.cgi?1094

anyway with this being implimented, i'm curious if anyone has ran across one
of these cd's and tried to copy it to a md digitally?  I have not purchased
an audio cd in quite a while since i've not heard anything i like recently
so i dont have any with this protection on it.  I am mostly curious if it
transfers over to the MD in a bad way?  what i'm asking is does this distort
digital recording also not just people ripping to MP3?  and what about on
cd/md combo decks that can do 2x and 4x recording (if there are 4x recorderd
i forget)  anyway if anyone has any info it would be appreciated.

Personally, I have no interest at all in those Mini-CD players, even
though they now play MP3's.  It may be physically small, but still
suffers all the drawbacks of CD-R/RW, such as the inability to
copy/move/edit tracks, to record 1 track at a time, etc.
Basically it is the same thing as regular CD-R/RW MP3 players, just
smaller.

I don't have any interesting in purchasing one of these until it becomes
a widely accepted standard.  If this doesn't happen, then I'll never get
one.  For me, MD still seems like a more elegant solution.  If NetMD is
as good as I'm hoping it is, I would definitely prefer NetMD recorder
over a Mini-CD player.  I have the habit of hearing 1 new song on the
radio that I like, I download the MP3, then I record it to the current
MD that I've been listening to in the car.  I do this frequently.  I
would hate to have to wait till I have a small collection of MP3's
before I can burn them to a Mini-CD.

 Most HiFi VCRs do support this form of recording. This can be done by
 selecting LINE-IN on the VCR and hooking up a radio tuner to the audio
 inputs. You don't hook anything up to the video inputs.

This isn't true of VHS HiFi machines I've tried in the UK: they need a
video signal at the same time, or they simply won't record. Probably
the video is required for locking the speed of the tape transport. But
you can feed them with a dummy video source in parallel with your
radio -- even an old games console will do, if it outputs something
approximating to a broadcast waveform.

Up to a few months ago I used MiniDiscs for recording radio, but now I
use a PC with digital satellite card, streaming the DVB data direct to
hard disc. In Europe, digital radio programmes are broadcast in mp2
form, mostly in stereo at 128, 192 or 256kbit/s, depending on the
broadcaster, although there's one mono DAB station hereabouts that's
at only 64kbit/s. A hard disc of the capacity routinely fitted to new
PCs could record continuously for two or three weeks, Windows
permitting. I cut up the recordings afterwards with MP3 Butcher (it
handles mp2 too) and use CD-R for any I want to keep; it's possible to
get 6-10 hours of stereo on to a single CD-R, depending on the data
rate. Cost of the recording medium is incredibly low and playback
quality is identical to the original broadcasts -- which cannot be
said of MD recordings.

I switched to using CD-Rs when a two-hour programme I like suddenly
became available in stereo. I could have bought an LP-capable MD
machine instead. But its recordings would have been unplayable on my
other MD machines, which would have thus instantly become useless.

RE: MD: Recording MDs with microphones...

2001-07-30 Thread Timothy Stockman


On the subject of building your own mixing system for MD, what do you find
lacking in commercially available mixers that would prompt you want to build
your own?  I can see that battery power and small size could be requirements
not met by many mixers.

In addition to the requirements you mention above:

1.  Plug-in power for inexpensive, high quality electret microphones.
2.  Reduced number of physical controls through software.  (Use a few rotary
  encoders to replace a lot of potentiometers.)
3.  Adjust levels *before* the A/D to prevent overload while maximizing dynamic
   range.  Most modern MD recorders have fixed gain *berfore* the A/D; not a
   good thing!

Also, why add the A/D?  Are MD's converters lacking?  (Or is it that the
digital out is an advantage if it results in the automatic level control
being bypassed.) 

The extremely low voltages and long battery endurance of modern portable
MD players must be made at a trade-off to audio quality.  Also, their small size
makes proper shilelding and isolation of the analog section difficult.

One other advantage of one of the Crystal Seminconductor A/D chips I've
been looking at is that it incorporates a metering circuit that gives an accurate
digital readout in 1 dB steps down to -70 dB.  While working on a unrelated
project a few years ago, I used a 16 character x 2 line LCD as a high resoltion
analog bar-graph meter with software controlled ballistics, as well as for its normal
text display function.

 What other features for MD would you look for in a mixer
design?

Since the proposed design would be software controlled, it could adjust the
channel level trim automatically for optimum performance.  The design would
sort of be like a modern point-and-shoot auto-focus camera.

RE: MD: Recording MDs with microphones...

2001-07-30 Thread Christopher Hicks


Curiously, I am currently contemplating designing a small digital mixer for 
location recording (not specifically to MD, but entirely usable with 
it).  My day job is DSP design (both hardware and software) for recording 
studio equipment (www.cedaraudio.com); my hobbies are performing and 
recording classical music (oh, and furniture making...). It recently 
occurred to me that a small digital mixer is quite feasible as a DIY 
project with careful design. Other complicated bits (such as FPGA designs 
and firmware) can be distributed in binary form.

 3.  Adjust levels *before* the A/D to prevent overload while maximizing 
dynamic
range.  Most modern MD recorders have fixed gain *berfore* the A/D; not a
good thing! 

It is technically correct that to maximise ADC performance you should do 
the gain control before the ADC; however, with modern ADC chips you can get 
extremely good performance (up to about 100dB dynamic range, depending on 
details) with this analogue gain control being pretty crude (I am planning 
3 or 4 settings spanning approximately a 50dB range). I agree that most 
small MD recorders do this to keep the cost down with little regard to 
audio quality, and probably don't even have the crude analogue gain 
switching that I suggest.

The performance I'm aiming for will not be the same as that obtained with 
truly professional ADCs costing megabucks, but the DSP will be second to 
none and I expect the unit overall to be good enough for producing 
commercial CD releases. The unit will be portable but not battery powered. 
I'd expect the parts cost to be of the order of $400 to $500 for a 1-off.

My project essentially comprises 8 XLR mic-line inputs, each with 
switchable gain and phantom power. The resulting audio is passed to a DSP 
which has independent level and pan controls for each channel, a master 
level control, and a parametric EQ on the output. It would be possible to 
have EQ on individual channels but it would make the control surface either 
expensive, or fiddly to use, and I'd rarely use it in my application 
anyway. As well as the digital master out (dithered/truncated as necessary) 
there is a separate analogue monitor out which will drive headphones, but 
which is really designed to drive a pair of active monitor speakers 
directly. This monitor out normally follows the main mix, but also allows 
solo and PFL functions which don't interfere with the main mix (which is 
what gets recorded). There will be decent level meters on the monitor out. 
The control surface will probably comprise 9 faders (8 inputs plus a 
master), plus an LCD display, soft keys and opto encoder to set other 
parameters.

The make-or-break of this project probably depends on whether I can get a 
hobbyist electronics magazine to publish the design. The purpose of this 
posting is too see if there is significant interest in this forum that I 
can use as leverage with potential publishers, so let me have your comments!

I would absolutely love something like this.  Even without the eq on
individual channels.

The other thing I'd love (while you're in the designing mood...) is a
small portable D/A converter with an eq in it.  It would take in optical
or coax S/PDIF and then have a digital eq, and then output a line level
signal.  Perhaps if you just added a digital input to your mixer above,
which would also be useful as an alternate clock source.

Re: MD: Recording audio to video tapes

Gary Gilliland wrote:
4. VHS Hi-Fi is not digital and is usually implemented poorly for
critical recording in all but really expensive pro decks.

Whether it's digital or not is largely irrelevant here. What matters is the
sound quality, and I don't think MP3s are going to give you incredibly
better sound quality.

As I said before, the drawback to that is 2 or 6 hours to a tape. I agree
that at 6-hour speeds the sound wouldn't be as good as at 2-hour speeds, but
the audio quality doesn't drop at all as much as the video quality between
SP and EP. At standard speeds (2-hour), even on a mid-level hi-fi VCR, IMO
the sound of VHS is better than MP3. But if he's not looking for the best
sound quality, and just wants to review some radio programs, then 6 hours of
VHS is a pretty good way to do it, and certainly a lot easier that dealing
with recording/ripping MP3s.

As for finding content, some VCRs (my Mitsubishi is one) allows you to place
index marks on your tapes that work just like track marks. Not all do, but
if you do it's a great feature.

Not sure what this means, Larry. MP3 is compressed audio, but not only that,
even at the highest bitrate it's inferior compression to our beloved ATRAC.
In my mind, that makes the problem the format, since even the best hardware
is limited by the format.

Perhaps Dan has very high end equipment, but as impressed as I was
with Hi-Fi video when they first came out (both VHS and Beta) I don't
think that the sound quality is as good as many of the cuts on the
MP3 CDs that I make.

Perhaps it is our systems. Certainly possible. But I don't have high-end
video equipment, just a nice Mitsubishi Hi-Fi VCR (although an older model
from when Mitsubishi was the cream of the consumer crop for VCRs ;) )

Are referring to the CS5360 or the CS5334 ADCs?  I think these chips consume
~350mW.  I assume that you mix 6-8 channels of analog down to 2, then
digitize. So with 6 analog channels, each with programmable gain (and
possibly eq), and the other circuitry and microcontroller you're well over
1/2 watt--roughly 20 hrs. with 3-4 AA cells-- is this what you have in mind
for a portable MD system?  I guess that's not bad, but I would think that
you would want to use Crystal's CS53L32 for this application, which brings
power consumption down for this system.  You lose the peak detect metering,
though.

Sorry, I'm not sure what you mean here?

Also, I would think that some MD titling interface built into the mixer

All I do is hook up my MD recorder to the line out of my soundcard (no USB

I use LP2 compression so I basically get a 160 min mix that you can't buy in
