Turbo Sound Pro (SAA1099)
ZXNet echo conference «hardware.zx»
Hello, CHRV
I immediately said that it would have been easier to do it this way.. (about CAA1099)
It seems the answer was the availability of components...
Hello, CHRV
It would be nice to build a sound card using such components.
LPC21xx (ARM 60mips) 3-5$
1 meter of static
2 inexpensive DACs
The final price is up to $15.
The speed would be enough to emulate two AY and GS.
Plus add your own work protocol to use everything
lpc resources.
Hello Valen
Val> For final price up to $15.
you need to add at least the price of tram tickets - it will just double :D
Hello, psb
psb> a dubious proposal, if you emulate everything honestly, it won’t work 100%
psb> so if it's fake, then of course what the hell...
why won't it work? Resampling (which has resources) is not needed if you have int
at 220khz (for AY). It is enough to emulate GS at the command level. RIFF tracker

Hello Valen
Val> The speed would be enough to emulate two AY and GS.
dubious proposal;) if you emulate everything honestly, it won’t turn out 100% like that;)
if it's fake, then of course :) what the hell...
Hello SMT
SMT> GS is enough to emulate at the command level. RIFF tracker
SMT>donate
Yeah, then you can completely throw the real thing in the trash and use emulsifiers. What the
is that nonsense? Why do we need a GS that only executes stupid commands?
Then it will have to be called GS-Castration edition.
Hello SMT
SMT> why won't it work? Resampling (which has resources) is not needed if
SMT> set int to 220khz (for AY).
of course int. current it turns out that you need to emulate 2 AY.. maybe it will work, no
I know.. I’m not sure somehow that it will be enough for 2.. but if Robus is used for coding
If so, that’s enough :) there are few such maniacs...
SMT> GS is enough to emulate at the command level. RIFF tracker
SMT>donate
oh well, it’ll be nonsense .. GS was special because it had an additional computer,
additional memory.. I even remade Global Comander and TRMSHOB for it
memory.. RAP also.. what is standard? a small pile of toys?
IMHO, if you don’t do 100% GS, then it’s something completely new and incompatible.. but
much more powerful! so that it can play mp3 at least.. why is it in place?
trample? The main thing here is not to lose your head ;)
Hello, Evgeny Muchkin
As for SAA - it is slightly different from 2*AY, and it is fatal for them
compatibility even if we allow the possibility of an intermediate controller
preparing data for it. small trouble - noise mixing
generators according to a different scheme (one on the right, the other on the left). significant
Trouble - ways to set the frequency of these noise generators (see docs). So S.A.A.
can only be used as SAA...
Hello, psb
psb> so that MP3 can be played
Will you load a lot of them from a floppy disk? :/
Hello, psb
psb> so that MP3 can be played at least.. Why stagnate?
I sleep and see a full-fledged editor for creating normal digital music for
128k Spectrum with trdos... And I can also imagine how much it will be in mp3 later
convert :wink;
Think; at least you're talking...
For me, the problem of speck is not in the sound at all.. For a start it would be nice to have it
speed up and improve the video...
Hello new art
new> making the Spectrum a Spectrum, that is, something (even though
new> restrictions) something unusual, special.
I fully support!!!
Hello, psb
If you really want to listen to MP3 while typing, it’s easier to turn on
any player, fortunately they cost just a penny now. The only reason for
MP3 could be useful - this is for dubbing toys, in the sense of music. But on
You can't play back a lot of MP3s, even with a screw. It is worth noting that the screw
broken into “partitions” the size of a standard holey floppy disk. So
The only solution for now seems to be storing music data in a scripted
video, with real-time playback. Maximum possible use of samples
not a large volume.
Hello new art
new> How many of them will you load from a floppy disk?
Sorry, there are already screws.. and agree, the spec will handle a flow of 40 kbytes/sec.. this
for mp3 with max. bitrate. I’ll say more, I think, even if I write it in a primitive way
task manager, you can then do, for example, a text editor, type
text, and an mp3 will play in the background (the editor doesn’t consume many resources)... and in
everything is in that spirit..
key> I sleep and see a full-fledged editor for creating a normal digital one
key> music for 128k Spectrum with trdos... And I can also imagine how much it is
key> will then be converted to mp3
why bother with 128k spec + trdos? the main thing, IMHO, is that it works in real life
this, but where it is made is not so important... but for hardware the main thing is that it does not
messed up the computer circuit when connecting... i.e. either to the system connector, or to the processor
just soldered... with the same mp3, you will need a screw. and the screw controller
connects easily.
The real question here is whether all this is necessary. there is GS, but its people are not so much
and uses it (for the most part).. there are a lot of docks, I don’t want to do it, but it’s not fate
that means... but new options are offered, but why? now under new, even
The coolest thing is that no one will rush to do anything. Yes, and this is not new, it’s not offered
much better(?) than the old one.. if we’re going to do something more sophisticated, thenso that at least there is an opportunity to play mp3. IMHO.
new> AY, ZX GFX, Z80 - all these are things that make the Spectrum a Spectrum, that is
new> something (albeit due to limitations) something unusual, special.
Is that why you didn’t finish the video player? because it's alien
Is the piece of iron in use?
again IMHO, but the main thing is that AY, ZX GFX and Z80 _remain_..
Hello Mike
Mik> But you can’t play a lot of MP3 on the spec, even with a screw. Worth

Mik> The maximum possible use of samples of small volume.
first of all. with a screw you can reproduce a lot. and toys can be sounded like this,
wow! It depends on how you approach the matter. if there is an mp3 player
have 16 meters on board, then you can do just a hell of a lot
everything!!! and even 4 meters, what’s up... consider it the same GS, he can play
mp3 samples :) the question is, if you put all these 4 or 16 meters of sounds into it,
then it will be quite long.. but even if you just play an mp3 stream, then that’s it
A solid buffer will also be needed.
secondly. What kind of screw are the partitions from the floppy disk on? IMHO, stop suffering
bullshit and all that.. the screw is normal - it’s in fat16 or fat32. and write this down
a screw on a pussy is easier. Or are we again stuck on the fact that EVERYTHING needs to be done on spec?
Maybe we can burn CDs later on a speck?
thirdly. You can store music data in any way, but it’s smarter tostandard screw with veil. and you can play them even on AY. at least a song for half an hour
record and play in real time. in the case of a veil of body movements there will be
less ;)
if you don’t know, then I calmly played music on covoks in stereo, 8 bits,
44100Hz. this is real! Moreover, the quality is very decent for spec! and this,
consider it without any sound accelerators. but we want THINGS, right? because
I only see mp3...
new> No, because we've played enough.
new> Everything that was interesting to do was done.
heh.. me too.. but I still don’t lose hope that I’ll finish the thread someday :)
not everyone just saw...
and as for the subject... personally, I was not at all impressed by the sound of the music from
collection.. I’d rather listen to something on 15 channels AY :))) it’s a pity there’s no such thing;)
Hello, psb
psb> is this why you didn’t finish the video player? because
psb> is a foreign piece of hardware being used?
No, because we've played enough.
Everything that was interesting to do was done.
Hello, psb
psb> IMHO, stop suffering with bullshit and all that.. the screw is normal - it's in
psb> fat16 or fat32.
So come on then, stop with the bullshit. Hey people, a lot of people have baked under a veil
does it work? Aww, is there at least one person? I don't know anyone like that. Everyone usually
holey images. The only exception is the Sprinter. Those. the task comes down to
reviving the latter as a manufactured and sold product.
psb> and it’s easier to write such a screw on a computer. or again we run into the fact that
psb> that EVERYTHING needs to be done on spec? maybe we can burn the CD later on
psb> spec?
Aren't you funny yourself? Bravo! :v2_clapp; If; I will record on my pussy
files on veil and burned on CD, then maybe I’ll listen to them on
pisyuke, what to use to poke the screw back and forth??? Has such an idea ever occurred to you? On
Even MP3 players have already been written for the pussy! :) Yes, and then the spec can be emulated
on the pussy and does not suffer.
So let's get back to the question about SAA1099.
Hello Mike
Mik> Everyone usually has shitty images.
I don't have them and never have. and it couldn’t be, because it’s elementary for me
There was no place to fix the ROM. and in addition to all this (aren’t we even talking about Scorpio?),
IMHO, it's terribly inconvenient to push floppy disks... it seemed to me that it was even
more inconvenient than sticking real ones.. only more reliable.. + in Scorpovskaya
The current implementation of 3d13 worked, which is very bad. again, it’s very bad for me, no
I know what _everyone_ is used to..
and phat.. yes, there are no programs yet. once upon a time there were no progs for flops, which are fatal
understood... however, veils are more progressive than images.
Mik> The only exception is the Sprinter.
but this is finally not a spec. IMHO, screw it..
SamCoupe also has a spec mode, but this does not make it a spec...
Mik> If I record files on a pussy and burn them onto a CD,
Mik> then maybe I’ll listen to them on my PC instead of plugging the screw
Mik> back and forth ??? Has such an idea ever occurred to you? Even on the pussy
Mik> MP3 players have already been written! Yes, and then the spec can be emulated on
Mik> the pussy doesn’t suffer.
the question is whose pussy you will do it on. a lot of whatthey want to do it on spec, they have been on PC for a long time. and much more convenient. we're talking about
not what you will do it on, but where will you do it later
watch/listen/play!
and this thought came to me. a lot comes from life. I haven't had one for a long time
it was a bitch, but I needed to get music from somewhere to write a player,
playing from floppy disks (even though no one needs it right now). with your approach it's not at all
it wouldn’t be, because even now there’s no place to get real music on spec.
and then, when I already had a pussy, I wanted to make a high-quality music player,
and then the video. Then I was JUST INTERESTED in doing it. at least for
yourself. I’m even a little proud that I specked it at 3.5 MHz, without any hardware features for it
capable! 10 years ago we didn’t even think about this... I’m just as interested in
mp3.
Of course everything is written on PC. there is much more and better stuff there ;) then why are you
are you doing here?
and this.. explain where you will get music at least for the same GS? how do you like her
Will you rewrite it to your screw with trdos images? what programs, etc.?
Hello demon_zx
dem> Who asked who was wearing a spec? Well, I have two screws, one
dem> fat16 is another fat32, and everything rules normally.
How do you use this on your spec, under what AXIS? And what a spec
?
Hello, psb
psb> and fat.. yes, there are no programs yet. once upon a time there were no progs for flops,
psb> who understood veils... however, veils are more progressive than images.
Naturally more progressive, and NTFS is even more progressive, but you have to really look
on things - there is no full-fledged OS running on FAT on the spec.
psb> and this is finally not a spec. IMHO, what the hell..
psb> SamCoupe also has a spec mode, but that doesn't make it a spec
psb> becomes..
psb>
This is just a very spec, in all respects spec. The processor has
Z80-compatible, the chipset supports all HARDWARE, has all ports and at the same time
is not an emulator. Or is everything above IBM PC XT no longer a piece of cake? :v2_laugh;
A; everything that starts from PPC is no longer a Mac?
psb> the question is on whose pussy you will do it. a lot of
psb> what they want to do on spec has already been on PC for a long time. and much
psb> is more convenient. it's not about what you will do it on, but where you will be
psb> you will watch/listen/run this!
psb>
In my own way, of course. Why should I listen to MP3 on spec if it does this?
can't it be ok? Despite the fact that the task is to LISTEN TO MUSIC, and not to listenmusic on spec.
psb> of course everything is written on PC. there is much more and better stuff there;) then
psb> what are you doing here?
psb>
I’m trying to take part in the discussion of the topic about SAA related specifically to SPECU, and
not to the PC. And I’m not pushing ideas about MP3 that are not related to the topic of the topic and are
so far, very difficult to implement.
psb> and this.. explain where you will get music at least for the same GS? how
psb> will you rewrite it on your screw with trdos images? what programs and
psb> etc.?
Where and everything - on the internet for example. Or I’ll write it myself. I only have GS
unfortunately no.
psb> how will you rewrite it on your screw with trdos images? what
psb> programs, etc.?
Any, fortunately their sea has been done. Only I don’t have a screw on the spec either, and also
unfortunately. I didn’t buy either GS or SMUC at one time, but now they’re not easy
get it.
Hello Mike
Mik> Naturally more progressive, and NTFS is even more progressive, but it needs to be real
Mik> look at things - there is no full-fledged OS running on FAT on the spec.
Yeah, you have to look at things realistically: it’s much easier to make a veil than an ntfs. him
They even implement it on controllers. he's EVERYWHERE!
Mik> And everything that, starting from PPC, is no longer a Mac?
Is this a "Pegasus is an Amiga" question?
SC was not conceived as a spec. There's even a different screen. there's just hv emulation..
Mik> In your own way, naturally.
That's the point. when you have your own (or do we already think that everyone has one?) and
you just want to listen to music, and you can listen to it... and another thing,
when you feel that your spec is playing! it's like demos, there wouldn't be any
It would be funny if all the effects were calculated in advance..
Mik> I'm trying to take part in the discussion of the topic about SAA related specifically to
Mik> SPEC, and not to the PC. I don’t push ideas about MP3 that are not related to the topic
Mik> topic and are so far very difficult to implement.
well, yes. We moved a little away from the topic, but nevertheless, it’s about sound and new
cards... and there is nothing difficult to implement. you can screw the same arm7,
put some memory and a hardware MP3 decoder. and it will work! and eventhis hardware decoder can be connected to GS, but these are not the most successful
options.. to do well, you have to think;)
Mik> Any, fortunately their sea has been done. Only the screws are on my spec too
Mik> no, and also unfortunately. I didn’t buy either GS or SMUC at one time, but
Mik> now they are not easy to get.
right, and there is no Internet on the spec yet, so you will use PC, floppy disks and
FAT;))) and stupidly transfer these floppy disks with a copier to images on a screw .. and
Each mod you have will be divided into a bunch of files.. instead of just
write down a normal stupid screw.
oh, yes, there’s no screw.. what images.. we’re just too much to talk about;)
you just need to understand what can be implemented in the near future and what
no.
That's it, enough offtopic :)
Hello Mike
Who asked who had a veil on the spec? Well, I have two screws, one fat16 and the other
Fat32, and everything works fine.
Hello, psb
psb> SC was not conceived as a spec. There's even a different screen. it just is
psb> hv-emulation..
It was conceived just as a continuation of the Spectrum. And he has such a screen, coupled with
he has 3 new ones, one of which was already in Timex. HWMC or "attribute per byte"
called :) And Spectrum “emulation” is comparable to 48K emulation at 128K.

Hello, psb
psb> SC was not conceived as a spec. There's even a different screen. it just is
psb> hv-emulation..
What is emulation? This is the formation of the functions of the emulated device by
by means of certain algorithms created by the programmer. So ? In Sprinter
nothing is emulated, the same Z84 is present there, live, real, the same
a set of loose powder inside PPLM, the same drive controller in the form of VG93, etc.
The only thing that is not real there is AY, it was also shoved into PPLM, but this
nevertheless, it is not software emulation and not even entirely hardware emulation, because
PPLM does not emulate it, but contains it internally. By the way, the same language used
when programming PPLM Altera, can also be used as a custom description
chips for manufacturing, including real AY. So emulation in this
question is a very conditional concept.
psb> you can screw the same arm7, install some memory and hardware
psb> MP3 decoder. and it will work!
Only this will be correctly called: screw a speck to this structure, in
load. :v2_biggr;
psb>; that's right, and there is no Internet on spec yet
psb>
But it’s not your truth - it is.
psb> , so you will use PC, floppy disks and FAT;))) and stupidly distillpsb> copy these floppy disks onto images on a screw.. and you have every mod
psb> will be split into a bunch of files.. instead of just normal
psb> stupid screw write everything down.
I won’t be stupid, I’ll be smart. :v2_laugh; AND; not instead of that, but after non-existence
that.
psb> oh, yes, there’s no screw.. what images.. we’re just too much to talk about;)
psb> you just need to understand what can be implemented in the near future
psb> and what not.
You - it looks like yes. And it’s not our fault that SMUC is no longer available now, but in those days
times, for me it was a very tangible amount.
Hello, psb
psb> example? how to look at mail? download files? ICQ? ...
There is definitely a soap dish (POP3, SMTP is meant), I know the person who does the soap
only from the spec having his only one and no pussy. Something about files
people discussed it for a long time, I didn’t see it, but maybe they did something. And ICQ
I don’t use it at all, so it’s not even interesting.
Hello Mike
Mik> But your truth is not true.

Well, I know people who get soap using www->fido gates, but to
straight from the internet - I’ve never heard of this.
Hello Mike
Mik> There is definitely a soap dish (POP3, SMTP is meant), I know a person
Mik> which lathers only from the spec, having its only one and none
Mik> pisyukov.
someone, somewhere, somehow... everything you say here is just words. none
You haven’t given a real example here, you’re just arguing about what exists and what doesn’t. at
in general, no screw, no internet... where is this program? why is no one talking about her?
knows? There is software for Fido (you can also send email from it, for sure
You can also download files through it), many people have used it, but for the Internet so far except
ping nothing. and no one here even talked about their successes in this matter,
experiments, so we can assume that this does not exist..
I dare to assume that someone wrote something similar, but it’s so
raw, it’s not even worth posting. I can also write a program in half a week,
which from my computer (through my provider!!!) will somehow mail
send/receive. BUT, there will not be a normal TCP/IP stack (make
a simple parser, ala “so that it at least somehow works”), and no one except me
IT won't work. This is not software for working on the Internet.
Mik> Only this will be called correctly: screw to this structure
Mik> speck, to load. Did they also screw the spec onto the GS?;) or is it somehow the other way around?
Mik> Nothing is emulated in Sprinter, the same Z84 is present there
Mik> live, real, the same set of powder inside PPLM,
again the point: do you want to buy the Spectrum that the masses have or do you want
a car that has a sub-mode of the original spec? how many times have you tried?
make other screens? they are all better, prettier, faster, etc. but why them
no one supports? this is the answer to what Spectrum is for the masses and what is not,
what people need.. Sprinter is also not a spec (IMHO), it’s a different computer, in
which has only a sub-mode.

For starters, one tone lower. I don’t owe anything to you or anyone else here,
just like everyone else. Ferstein? :v2_mad; AND; let the lack of screw
you don't care - it's not your problem. And without the Internet I would not have written these lines.
psb> did you also screw the spec to the GS?;) or is it somehow the other way around?

Let's say they are on equal terms. This is a LAN. :)

psb> submode only.
Buying a sprinter, I'll have a Spectrum anyway. It's the Spectrum, not his
emulator And about the video modes. Do you play games on the PC? If yes, then
Of course, in a resolution no higher than 320X200 with 256 colors? Or do you put it higher?
It turns out a pisyuk with any resolution is a pisyuk, but spec is only when it’s not higher
256X192 with 16 colors per location? And who issued such a law? Maybe
Shall we write to Sinclair, asking him to judge us slaves? :v2_lol:

Hot Finnish guys, a couple more similar messages and I’ll cut....
Since SAA1099 was on a clone of SamCoupe and it can be used theoretically
on the spec (and Jiri Veleba has already done it practically), then it fits the discussion
iron...
And is allowed for discussion here. :v2_wink:
