Hello

The research behind our upcoming chipspeech product led us to develop a great interest on the different versions of the CPU and Speech ROMS (VSMs) that were shipped in the various revisions of the US speak and Spell. Earlier versions had bugs and a different word list than the final ones.

We (me and a few other researchers) so far have collected three different word list/roms for the main US Speak and Spell, but we feel there might be more than that out there.

We are looking specifically for the earliest "Buttons" versions that have date codes in 1978 and early 1979.
If you have one with a membrane keyboard, do not bother.

How to get the date code:

Whether or not it is circuit bent or broken makes little difference to us.
This is for research that will be published, not for inclusion in the software.

Thanks!

But can it do the voices from moe moe kyunstep?

Not from the part I've heard,  (http://chibitech.bandcamp.com/album/moe-moe-kyunstep)
which is really just using glides and voice-like pitches on 'normal' 2A03 waveforms,

You have another example?

Ha thanks guys!

This product is in my head non stop 80+hours a week for a year and more...
I'm slightly turning nuts.

If you have any questions do not hesitate to ask!

Just wait to see what we have in store smile

Edit, from the IIGS schematics I found, emulating the analog output of the chip would be best with a full IR (as i did with all the Amiga filters)  and not just a simple (one pole) RC filter.

Haven't done much work yet with the IIGS's Ensoniq DOC chip (same as in Ensoniq Mirage and ESQ1/m) - though I have all these devices -  The fact that the DOC uses 8bit PCM wavetables at varispeed using a 24 bit accumulator (aliasing fun) makes me feel this would be more suited for a chipsounds addition than an chipcrusher addition.

However, it might be interesting to investigate at which samplerate most game FX/dialogs were played at and that would give a relative close value.  As with the SID (the DOC's father), there surely is a magic SR setting where each sample is played without one been repeated or skipped.

You could set Resample at something between 8000 and 11025 and 8bits, then through the RC filter - need to calculate the value from schematics - or make an impulse), then through the IIGS speaker.

So in short I would need more time to investigate to make a 'valid' preset to emulate it.

Greaaat, reminds me of this http://www.audioease.com/Pages/Speakerp … phone.html
Chipcrusher was an instant buy smile

Thanks! Yeah, some co-workers here mentioned speakerphone after I already started working on some impulse stuff at home,
from what i can gather from their site its a great library with lots of great IRs that covers stuff I dont have, which is great.

Any good sources to share? what is similar and what not?
Thx

Most of the ADPCM variants have subtle differences which are interesting but less "in your face" like the transition from LPC10 to LPCM or PWM to LPCM.

I guess the hard part more than the encoding itself is the execution. To get the "Zero order hold" or PWM done accurately  I needed to have 3 different sample rate streams buffered at once, and _that_ is one of the hardest challenges i faced in my 15+ years doing DSP/C/C++.

Even so, the reported latency is currently slightly off, and i need to revisit it  ( that means crying in a fetal position for a while )

plgDavid: are there any older versions of chipsounds that run under 10.4 osx? Im sure probably not, and that this was the only thing stopping me from buying it, but its worth an ask eh?

*I remember now I was originally thinking about bidule, so the above question applies to bidule also smile

Current bidules should run 10.4, but only intel, but we only have 10.6+ test machines now. Older versions of chipsounds could work, but I just cant fathom to make available stuff that contains bugs I've fixed ages ago smile

How did you analyze the speakers etc ?

By sending test tones directly through the device's speakers - most of the time requires desoldering/soldering, closing the case, etc. I just made a small post about that process on the GBA SP:

is it possible to make something like this that simulates mp3/wma compression in real time? (disregarding any codec licensing issues)
it's kinda weird, but for a while now i've desperately want an effect that lets me sweep between 16 and 320kbps, or sidechain or whatever. like a really nasty filter/crusher with all the throaty artifacts and stuff.

Yes in fact fraunhofer has a product like that for some encodings:
http://www.iis.fraunhofer.de/en/bf/amm/ … lugin.html

The status of encoder licenses is that usually the OS vendor gives a license to the OS user for decoding purposes (sometimes for encoding), so some of our soundfile _decoding_ libraries use some platform specific hooks.

However encoding usually involves software license costs/patents license costs, which for a product like this might not be worth it, on top of most probably sounding totally different between MAC/PC.
