| Not as such - but using the directX api you could place
each of the four channels at each of the speakers - this
is how they intended to do an implementation of someones
surround system apparently.
I have every intention of writing something that
does this in the very near future - given I am now off work 'til
the 11th of Jan I have no excuse. I'll post a url when I have something
working.
I presume that wav files cope with four channels - from what I remeber
its a pretty flexible format....
Must put in a shout for the SBLive too - for what it costs its is a superb
card - really quiet (SNR). Until I can afford (and need) a mutli channel
card it is just the ticket!

What about MP3, which is arousing considerable controversy because thousands
of MP3 sites exist, Diamond Multimedia now makes a hardware MP3 player, and
the record industry is trying to kill it with a competing copy-protected,
encrypted format?
Do any of us download and/or listen to MP3s?
Do any of us have MP3 files of pieces on the web, either for sale or to give
away?
Does MP3 sound really good? Is it really adequate for complex music?
What are our plans to distribute, publish, or make money off our music?
What would we LIKE to be able to do with our music on the Web? Do we want to
handle all middle-man functions ourselves, or do we want someone to take on
the role of a record company, even if they just manage a Web site and broker
payment?
What about our friends who make other kinds of music (pop, straight
"classical" for live players, jazz, traditional) and their attitudes/plans
for MP3?
As for myself, since I don't have a publisher or a record company, I'm
planning to put up complete pieces as MP3 files on the Web as advertisement
and promotion until I do make a CD (I never will have a publisher!).

i've used recordit to create mpegs on a zip-disk. Classical
musics sounds not too bad, but when i've tried some of my music
created with csound, the result is awful to listen. (clicks, pops,
noise where there shouldn't be etc.) Apparently mpeg was created for
other kind of music.

Several Windows frontends are available for it as well. WinAmp is a

Are there example files, or a simple how-to, explaining how to use
DirectCsound with real-time audio input? I was excited to see this
feature mentioned in the docs a while back, but I couldn't find any
description of its implementation. I apologize if I'm overlooking the
obvious, but this has had me stumped for a while.

MP3 is a lossy compression format, and as such, it by definition has to
throw away part of the audio signal, never to be recovered. It uses a
frequency transform as part of the compression, which leads to certain
side effects. So the upshot is the following, in my opinion, compared
to uncompressed 44.1:
-General loss of high frequencies. These are considered less crucial.
-Less accuracy in mid and high frequencies. These are places where
approximations for compression take their toll.
-A small amount of time smearing for transients in general. This is due
to the effect of removing sound components from a frequency transform.
-Some loss of dynamic range.
These effects become more severe as the amount of compression
increases. Anyone who tells you that MP3 is "CD Quality" is fooling
themselves. I would compare it more closely to FM broadcast, minus the
severe loss of dynamic range associated with FM compression.
There also remain legal issues surrounding MP3. The process is
proprietary and owner by Fraunhofer (sp?). They have not been enforcing
their legal rights surrounding the players in an attempt to force a de
facto standard. However, just recently they have been making
indications that they are going to start going after the free
encoder-writers and charge them a license fee. The decoders will likely
remain free.

I use the MiXViews sound editor quite a bit. There is
an incompatibility between it and csound. MiXViews will
read an AIFF sound file, and save it only as type AIFC.
Csound doesn't seem to handle this, or at least not MXV's
AIFC's. When I attempt to read such a file with csound
or sndinfo, I get:
Compression Type is not FL32
I have contacted the author of MXV, and his response
was along the line that AIFF is from the 19'th century, and
that Csound should support AIFC. Perhaps csound does, but
does not agree with MXV as to format?
Thanks,
Toby

I use the MiXViews sound editor quite a bit. There is
an incompatibility between it and csound. MiXViews will
read an AIFF sound file, and save it only as type AIFC.
Csound doesn't seem to handle this, or at least not MXV's
AIFC's. When I attempt to read such a file with csound
or sndinfo, I get:
Compression Type is not FL32
I have contacted the author of MXV, and his response
was along the line that AIFF is from the 19'th century, and
that Csound should support AIFC. Perhaps csound does, but
does not agree with MXV as to format?
Thanks,
Toby

Interesting! Can you give any more details about the DirectX APIs
involved?
WAV files can cope wtih any number of channels (though cards and a lot
of software can't) - I have downloadable examples on my website.

hi yes,
I've spent the day reading about them and playing with some
of the stuff that comes with the directX 6 SDK - you can read
the manuals by joining the free part of MSDN (microsoft dev
network) and going to the developer library.
In short though you can have a number of channels - with the
SBLive drivers I have (not quite the latest) I've got 32. Each
channel can have spatialisation info including velocities. There
is a cool app that comes with the sdk that lets you set up
channels based on wave files - and then move them about. I set
up a interesting soundscape based on some loops made for other
bit of work - a tabla loop oscilating back and forth with orbiting
drones - sounded good.
For doing quad wav file playback it would be easy to place four channels
at the speaker locations. This does seem a little obtuse though - given
that the 3d sound stuff is part of the directX api (rather than SBLive per
se)
it would be interesting if some of this stuff was directly accessible in
DirectCSound - instead of the current scheme each instrument would be a
channel which you could also score a location for - it would need new
op codes though.
I should have modified the sample code mentioned above to play four channels
from CSound in the next couple of days so assuming it works I'll let you
have a copy.
hope this helps

Mp3 is a great format... it is intended to compress audio by filtering out

very little/no perceptible difference between it an uncompressed audio...
there have been studies at berkely and other such respectable places to try

Oh right, that makes sense, its based on DirectX-3D (which I do know
about - have the sdk, though I've managed to avoid actually programming
anything, so far...). I'm still concerned to find (affordable) cards
with multi-channel WAVE drivers, which can support Csound as-is, without
something like DirectX. Are there any plain-vanilla SBLive API's one
could use for basic quad output?
Your programming work sounds very interetsing - I would like to see the
code - I leave it to those actively working on DirectCsound to say
whether this is a viable route to take.

I would have to disagree with "very little/no perceptible difference
between it an uncompressed audio." I have done work relating to the
survival of audio features through an MP3 encode/decode and there is a
whale of a difference even at 320k (5:1 compression). The basic problem
is that the perceptual model requires that assumptions be made about
what is or isn't important. Try burning a CD of an uncompressed song
and a compressed/decompressed song and listen to them in a decent
stereo. If you can't tell the difference then you either got very lucky
with the material encoded or you are fooling yourself. Do you have any
documention of the Berkeley tests to which you are refering?
That said, I am not saying that its not a great thing that you can
distribute your music via MP3. It certainly beats RealAudio. This is
what the internet is for - for everyone to be able to become a
distributor of their own work without capital costs. I distribute all
of my software this way, which I could never do without the net.
As for why are the music companies unhappy about MP3, its not because
MP3 is the best posible format, but because people are stealing their
products. And MP3 often sounds better than a cassette, which may
undercut their sales there. Once bandwidth increases, people will
probably be stealing uncompressed audio via the net (and then movies,
etc...). MP3 is just the present compromise between sound quality and
bandwidth. But I think that it is a disservice to say that MP3 is "CD
Quality." It is hard enough to establish a quality standard without
diluting it unnecessarily. Part of csound is the ability to deliver
music at the highest possible quality on a given device (set your sr and
kr accordingly). And many are unhappy with the sound quality 44.1/16
uncompressed. But you work with what you have. But don't fool yourself
that it can't be better.

I have some to give away at:

Apparently the quality is similar to cassette tape without some of the

Well if it looks like someone actually likes my music I may try to move some
of the better stuff into the for sale category. I tried putting it at
www.spareroomstudio.com but they never did anything as far as I could tell
and now they have begun charging money to put your music up. www.mp3.com
seems like a more legitimate outfit and have two of my songs up although I
have submitted four. mp3.com has a lot of info about mp3. The mpeg encoder
I currently use is from:
http://www.isafeelin.org/soloh/mpegEnc.html
It does not seem to generate any glitches or pops but takes quite a while.
I use Winamp to listen to MP3's. (with the Cthugha plug-in)

Thanks for the music, which I'm enjoying via the FreePlay player as I write
this. It's fun. Again, what kind of studio did you use to make this? I
imagine at least some of it is Csound - how much? What bandwidth did you use
for the initial recording? And what MP3 encoding rate did you use?
I must say I'm surprised that more computer music people don't distribute
MP3s of their stuff. I can understand it for Paul Lansky, but what about
those of us who don't have a record contract, or whose recording company
doesn't deliver results when it comes to promotion and advertising? It seems
like a no-brain decision to give some music away, so that people can at
least hear enough to decide if they want more or want to pay. It's not
exactly hard to make these things, after all.
Of course there is a bind here that is becoming more and more exposed. Once
you have a digital object, all copies henceforth are essentially free to
make and easy as pie to steal. This is a situation that applies across many
fields and many sectors of the economy. Sun's giving away Java, Netscape's
giving away Navigator, bands are giving away prime cuts... how stable is
this situation? Is software compatible with capitalism, or does it tend to
the condition of anarchic socialism?

Not sure about the SBlive api - I've applied
to Creative for inclusion in their developer
program but I haven't heard anything yet -
there is very little programming info around
on either the DSP chip or the board. I will
make the source available with the player
as soon as I have finished it. I had a look at
your web site and read the Microsoft Wav
proposal - all extremely interesting - my goal
is to try and be able to play as many of your
files as possible.
Given the complete configurability of the SBlive
and the on going driver development program
Creative might well support the mutlichannel
stuff in the future - I'll drop them an e-mail.
Its odd writing C++ again - I abandoned it 3
years ago in favour of Java because I've been
doing distributed computing.

Hello all
Just a quick message to introduce myself to the list. I have only just
started working with Csound, so expect to be bombarded with idiotic
queries over the next few days ;-)
I'm running the Win95 version of Csound, currently using Omni Systems'
Csounder as a front end. My setup is P133/64Mb/3.2Gb EIDE/Event Gina
audio I/O. Other musical software I use includes Steinberg Wavelab and
Syntrillium Cool Edit Pro SE on the PC, and Steinberg Cubase V3.0 on the
ST. Musical outboard includes an Akai S2800 sampler, Alesis Quadraverb+
multi-FX, Novation BassStation analogue monosynth.
I am an experimental musician/sound-artist, currently working as
Nonlinear. At the moment, my interests are mostly with concepts of genre
- how genre conventions define the experiences of producing and
listening to music, and how these conventions can be modified and/or
intefered with, to disparate (but mostly critical) ends.
That's all for now.
Gareth

Is there any way to hook up Csound to SMPTE or some other form of
standard time code, so that the end product of the orc/sco can be synced
up to video, without having it transferred to a soundfile or DAT, first?
I've been wondering about this, lately.

"Big Dog" I did with a four track recorder a couple of synths & effects
processors, an 8-bit sound card for the voice samples and Cool Edit for the
vocal effects. It's about five years old now and I did not use any Csound.
I rescued it from the four-track master by digitizing it. (Matrix 6R, Roland
D10, Harmonica, PowerTracks, Fostex X-26 4-Track, Boss-SE70)
"Technology World" I used 90% Csound for generating the sounds. The only
things that did not use Csound were some of the whooshing noises which I
created by modifying Csound noises with CoolEdit and the Vocoder which was a
sample of my voice processed through a Csound vocoder. I assembled all of
the samples with Multiquence. Everything was recorded at 44.1 kHz and
encoded at 128 kBit/s.
".99c" started out as a single long improvised jam on the Matrix 6R recorded
live. I later added the rhythm and some embellishments generated with
Csound.
"Cosmic Forge" This was done at the same time as "Big Dog" and uses the same
gear with the addition of a DX-100.

I had to consider giving away the music, but it is fun to make and hopefully
some people will find it fun to listen to. It doesn't do much good sitting
on my computer or decaying on a cassette tape. If it were to start becoming
popular I could move it over to the pay section or perhaps make try to sell
some new stuff. Before MP3 there was really no good way to distribute music
over the net because the files were so large. With 10:1 compression it
becomes possible.
Someone who wants to make money from their music would want to be careful
how they do it. MP3's can be a powerful marketing tool if used correctly
but the music made available on MP3's can easily be pirated.

Hans Mikelson

I have recently gotten a friend interested in realtime MIDI input in
Csound. He has a Macintosh G3 300Mhz/160MB RAM (more than enough power.)
I am a PC user with an IBM Aptiva Pentium II 300Mhz/64MB RAM (still
lots of power but not as much as my friend) and I can acheive much lower
latency because I use Gabriel Maldonado's DirectSound 2.1 and he uses just
the regular version of Csound for Macintosh. Does MacOS have anything
analogous to DirectX for Windows, and are there any Csound versions that
use it? I checked the Leeds site and can't find anything that is clearly
labeled as such.
I was also wondering if there is a way to get Csound to accept program
changes. I've heard that it's very complicated, but I found a workaround
I want to try. My synthesizer (Roland GR30) allows a program change to be
accompanied by a bank change (controller 0 or 32.) Trouble is I can't
send the bank change without also sending a program change, which causes
Csound to crash. If I can't USE program change messages, then is there at
least an effective way to get Csound to IGNORE them?
Thanks everyone for your help. I know I've been picking the group's
collective brain a lot lately, and I promise I will contribute more once
I get a brain of my own!

I have some MP3 excerpts from my past and present music at
http://members.tripod.com/~fz3/anatemno/
As for the sound I also would disagree that it is CD-quality.
In special I am not so happy about the artifacts you get on
transient, hi-freq and noisy sounds.
But for the internet it is the most acceptable solution I think.

At present time there is not the software to do that task. But it is surely possible by
the hardware point of view. The SB live can handle up to 32 3D streams of audio, and up to
131 hardware channels of audio displaced in 4 audio output (8 audio output in the future).
It has also good effects as reverbs , chours, flangers etc, appliable at each audio
channel.

Yes. I don't go looking for pirated songs; MP3 is a handy way to hear
music by people with no other means of distribution.

...there's a silly multitrack acoustic song of mine there, and I have an
MP3 of an older computer-music piece made with Rt and cmix back in '92,
but I keep forgetting to upload that one.
> Does MP3 sound really good? Is it really adequate for complex music?
Probably adequate, but certainly by no means perfect. Sometimes there
are "whooshing" phase problems, and probably more subtle defects I
haven't noticed yet (I haven't yet heard MP3 on a really good sound
system).
I haven't seen anyone mention it in this thread yet, but there's another
format called Twin VQF (it's part of the MP4 project) which claims
better compression ratio AND better sound quality. I haven't yet heard
it for myself, but it's worth a look.

Hmm... all of the above?

THere's a hidden problem with this approach. Unless the crystal clocks
on the two soundcards (the gadget that generates the 44100 kHz clock
signal) are EXACTLY at the same frequency, you will notice that the
latency between the cards drifts. I was trying to do some multitracking
on my Linux box and having problems, and at one point I tried two cards
(a Soundblaster for output and a TB Malibu for input). During playback I
discovered that, even when I got the cards synced to start at the exact
same time, after one minute of recording they were off by a full second
or more, and it only got worse.
You may have better results using two of the exact same brand & model of
soundcard, but I wouldn't bet on it.
A very few soundcards do allow you to slave one soundcard to the clock
on the other soundcard. I have no idea what cards are available that do
this; it's not something your average consumer cares about at all, so
it's probably only on "pro" soundcards.
I'd say, buy one soundcard that actually works full duplex. What's the
SB-64 Gold's "duplex problem"? I thought that was supposed to be the one
SB card that actually worked well? But I don't have one, so I don't
know...
Check out Ensoniq Audio PCI. My TB Malibu works well, too. Both are
available for under $100 and have very good specs for such cheap
hardware.
Hope that helps,
