The best and easiest way to make sound programs is to get Calcmod 83+ and the songs that go with the zip file. THis can be found on this site. Calcmod can play music with stereo surround sound! Its the best thing yet for calc music. Look at the source code and readme files. They tell you how to write music. If anyone knows an easier way to get good music (MIDI format) on a calculator, please e-mail me.

Where dose the space for these wavs and midis come from. i know darn well music is BIG space which the Ti83 doesnt have

I don't see how it is possible to have sound on the ti83+. I heard of no sound card. No speaker. And anyway why have sound on the ti83+? Isn't that what computers, cd players, mp3 players, mp3 burners and stuff like that for? Someone fill me in on how this is done. Based on my knowledge, no soundcard, no sound.

AAAAHhahahahahahaa dam windows user! AHHAAAAAAA you have yet to grasp the full abilities of the link port/cable!

I to share your amazement.
This young TI Grrasss-Hoppaahhh has yet to benefit from
the potentials that the calcs. possess!

HHAAAAAAAAh, HHHAAh,.........HHAAAAAAAAAAA AAAAAAAAAhhh.

I think certain programs can send bytes through the port, causing a noise to be picked up in head phones (can be plugged in with an adaptor).

where can I buy an adaptor?

just go to radioshack and buy one and it is possible to get sound i have done it before

I don't think tere are any sounds in MIDI-format. However, when you are looking for music files, you will find lots of MIDIs on the net. Some calculators accidentally broadcast their linkport data to a very low AM signal, which can be picked up with some AM radios. The only remaining problem is to get your calculator to convert and broadcast MIDIs so that it can be picked up. Most MIDI sequencer plugins for PC exceed the very very limited memory space of, for example, the TI83+.
But if you need MIDIs, try www.classicalarchives.com

The calculator also sends on FM. Not FM-Stereo.

Can someone in America that has an AM-Stereo Radio and an TI83(+), can you please put the TI close to that Stereo AM Radio and listed/look if you use a Stereo Audio program if that AM-Stereo radio detects Stereo in the signal and output a Stereo signal on your Radio?

For FM the sound is sometimes Stereo when sending data but never when playing sound.

I have found that an AM/FM mini radio receiver works best for playing calculator sounds over the AM band. There is no extra static and picks up the sounds from the TI-83+ easily. The best frequency is indeed at the low end of the AM band.

Using the radio, I found that the sounds that the radio picks up are from frequencies created by a specific part of the hardware in the calculator (there's static until a button is pressed. You can hear a ping when you press the ON button and a bonk when pressing other keya). Does anyone know which part of the calculator creates these frequencies? I'm just curious.

Is there such thing as sound programs for the 83+. Please tell me more.
I'm at Bear_den04@hotmail.

Anyone have any ideas on how (if possible..) to wire a speaker while using the new TI Keyboard???

Hehe, the 83+ needs more data ports :D

Yes, use resistors!

I can send data and listen to the bytes (very interesting but not very nice to listen to for a long time)

Put 2 2,5KiloOhm resistors between the left + and the right + link-output and the headphone (keyboard must be connected straight ahead as always). You can also use it during datacasting.

Please feel free to look at the upcoming TI83(+) forum and look for Upcoming 3D ASM Game for TI83(+). This game has Sound and Link (not yet at the same time but hopefully implented at the same time).

Only problem is that if you type there are short interupts when data is sended from keyboard to TI. And also I don't know if you can use the external TI Keyboard when using a program/game cause most games disable interupt programs (I disable interupts too, cause interupts make sound blurry and the program slow)

When constructing a sound card for the TI calculators, remember to ground your connections. Otherwise, you will send feedback into you data port, and possibly short it out.

? Grounding connections?

I put 2 2,5 KiloOhm resistors between the two + connectors (Stereo plug has two + connectors (tip and ring) and one - connector (ground). To avoid damage and making the datalines low put two 2,5 KiloOhm resistors between calc and headphone. -/Ground can be connected straight ahead from headphone to calc.

If you use a powered speakers or an amplifier, no resistors are needed. Never use one resistor and shortcut the two + to each other. You have to use two resistors!

Why do we need a soundcard? Whatever happened to the good old linkport? And stereo sound (Gameboy quality) is certainly possible. Just look at Calcmod. Those files don't take up much space at all.

You're right,

No soundcard needed

In fact if you should make hardware to connect to the link port you need drivers and software and all that other shit to use that soundcard.

No Link-Audio is plain, fast and pretty good.

And if you want to record audio I suggest you to use your computer or buy a Memo-Recorder, because even if the link port could capture audio you will need a lot more memory otherwise you can only record 10 seconds of audio, maybe 1 minute if you're able to port a codec like MP3 or MSAudio to your TI83(+).

yeah we need a compression algorithmn for 83+ sound. On a computer, mp3's take roughly 1/10 as much memory as wav's. Imagine... a minute and a half of audio rather than ten seconds!

What AM Frequency does the TI-83 plus broadcast at?

I have gotten it to an all static station, when I turn it on, the static gets louder, and when I play a sound with a program, there is almost no static at all...
Somewhere around AM 110...

I use a TI-84 Plus Silver Edition. I dunno if the radio or the calculator is weak, but just about the only way I could hear music through an AM radio was slightly past 1000 Khz. It was very krappy so I went out and bought a 3.5mm>2.5mm adapter from RadioShack that works much better.

Now I hate my town even more since I found out how stupid the people at radioshack here are... "I need an 1/8 inch to 2.5mm converter" (being in a hurry not thinking about the metric/inch crap) clerk-"thats the same thing" ... my fist stopped right in front of his face. Anyway- it's not supposed to put out signal, and as long as you have a lot of extra broken crap around the house you shouldn't have to buy anything. I took a 2.5mm jack, split it, and hooked it up to a 3.5mm port I got off an old radio, which had resistors left on it. Now I can get sound out of both speakers, use dif headphones, and it saved about $5-10 (resistors, port, jack, etc.). Anything can be modded with old parts, a hammer, solder, and ingenuity.
