Programming Sound and Speech
Video about sound and speech (11:40)

This video covers many of the sound-specific features and commands available in TI BASIC, Extended BASIC, and assembly language, as well as TI's Speech Synthesizer peripheral. The examples of the computer's sound and speech operations are shown using a combination of a real 4A console and the Classic99 emulator.

We look at:

  • The computer's sound controller, the TMS9919/SN94624
  • The tone and noise channels of the sound system
  • Sound commands and features in BASIC and Extended BASIC
  • Using music frequencies
  • The ways that sound is used in TI game cartridges
  • The Speech Synthesizer's processor, the TMS5220
  • Text-to-speech with Terminal Emulator II
  • Resident vocabulary speech with Extended BASIC
  • 5220 Linear Predictive Coding (LPC) overview
  • Composing new speech with Extended BASIC
  • Speech emulation deficiencies

SPACELIKE (TI BASIC)

A demonstration of using the three tone channels.

10 CALL SCREEN(2) 20 CALL COLOR(2,7,1) 25 CALL CHAR(42,"1018141272F4F060") 30 CALL CLEAR 40 Y=40000 50 Z=40000 60 X=INT(RND*1000)+200 70 PRINT 80 CALL HCHAR(23,(X-200)*0.03+1,42) 90 FOR A=0 TO 20 STEP 2 100 CALL COLOR(2,A/2+3,1) 110 CALL SOUND(-500,X,30-A,Y,ABS(A-10),Z,10+A) 120 NEXT A 130 Z=Y 140 Y=X 150 GOTO 60

FALLSPLAT (TI Extended BASIC)

A demonstration of tone and noise channels with sprites.

BLAHBLAH (TI Extended BASIC)

This program demonstrates keeping the music note frequencies in an array and storing a song in an array.
