Yo People

Check out Mario that has good sound

Dude, first comment

I have written and am polishing up a 3D graphing package (ti-basic) for the 86.
It's somewhat slow, but it is true 3d nonetheless.

If anyone wants to do an assembly version, let me know.

oops, sorry
admin pls remove this
it's in the wrong section!

Hey men, i think that idea is really cool, i have a CAL3 class and i can't even graph on 3D. SO making a 3D program is really cool.
Unfortunately, i can't program assembly either but its cool if you at first write theprogram in TI-86 BASIC.

I'm making a 1- and 2-bit wave player based on Andrew Waser's 86wav program. I've already written about 6 different programs to play the 2-bit sound, each with different sound qualities. I'll post some samples and ask people which method sounds best. I'm also trying to compress the sound data to a reasonable size, especially for 2-bit files. I've tried a PCX-type compression, which is very simple, but it shed off only 10 percent of the 2-bit file's size. Any other ideas for compression would be appreciated.
In addition to a simple sound player, I was thinking about making a video and audio player. I think it's possible to have 1-bit sound play along with a small b/w or 4 gray compressed video. Of course, a video could only be up to, say, 10-20 seconds long on an 86. Tell me what you think about all of this.

you might try using a frequency compression. Find how long a frequency is sustained by counting how many 2-bit pairs go unchanged and seeing how long this count will go unchanged. Use PCX type compression on this count. A frequency should be able to be derived from this count after PCX decompression. The Frequency should be more stable than the 2-bit pairs.

the animation studio should be improved to include sound with the extracted files....email me if you agree

I don't think that doing a PCX compression twice would work much better than only once. I've got another idea for using a similar method that will compress sounds much better. I'm not telling anyone my ideas, because I don't want others to use my method in a program before I do!

P.S. I'm also going to use this compression for use in video applications. That is, b/w or grayscale videos with sound on the calculator!

Well, I haven't done anything on this for a long time now. It's been 1.5 years since I first posted this message!

I'm now thinking of using a technique similar to DSD (which I've found is really just 1-bit PCM encoded using a feedback loop for error correction) to get better-quality sound out of 1-bit quality.

Anyway, I'll upload a program Real Soon Now I hope if it is satisfactory.

I am working on a program that is basically like a MIDI player. It will use "music" that is stored in a string in "notes" like F,A,C........... without the commas of course. And it will have special characters that make notes in-between. The string will not be case sensitive. And if i get around to it, I might make an on-calc editor that playes the notes as you type them so you can hear what it sounds like before you save it. Also, I might make a windows program that converts songs to strings, but since there are I'm sure programs that convert songs to midi, I might make it to where it converts the actual midi file. Any help/comments are welcome. Email me b/c i dont look at message boards that much.
