Free 3d spatialization software for linux

3D Spatialization of Sound is a Linux/X11 port of the 3D spatializer library from the CRC.

This program creates "directional" stereo sound from mono source. CRC folks told me I shouldnt have raised the sampling frequency without adjusting other stuff.

Oh well. This was a proof-of-concept type project anyway. I think to get correct 3D effect, you need to drop sampling rate back to 11025.

To Build the X11 implementation:

1. make
2. cp audio-filter /usr/local/bin
3. mpg123 -m -s some_music.mp3 | audio-filter | aplay -S -s 44100 -f s16l -

audio-filter is implemented as a filter, it reads signed 16 bit mono input at 44100 khz from stdin, and outputs signed 16 bit stereo, 44100 khz output to stdout. You can replace mpg123 with any sound source generating signed 16 bit 44100 khz mono signal. "aplay" is a sound player utility which comes with ALSA linux sound driver. You can use "play" from the sox package, or "ampctl", or any other sound player that would read 44100 khz, signed 16 bit stereo raw data from stdin. For "sox" play script, you would replace "aplay" command line with "play -c 2 -f s -r 44100 -s w -t raw -"

If everything is good, a 640x480 window will come up, with some cryptic writing on the top, a filled circle with an arrow pointing right, and a empty circle slightly to the right of the circle with arrow.

NOTE, that just like in the original Windows implementation, the axiss are reversed. The arrow on the "head" is pointing "forward". So, in the default startup configuration, the sound is located in front of the listener. Moving the sound source "up" moves it to the left of the listener, and "down", to the right. You can visualize this well if you turn your monitor 90 degrees counter
clock wise.

The filled circle with an arrow is your "head"
The empty circle is the "sound source"

You can move the "sound source" around by clicking the mouse at any position in the window, or by clicking on the "sound source" circle, and dragging it to the desired position. Soundfield will be dynamically updated as you do this.

You can move the "head" by moving the mouse to desired position, and right-clicking. The "head" icon will move to the new position and soundfield will be updated.

Invasion 3D is a fun and addictive 3D arcade game!
The idea for Invasion 3D came during the summer of 2004, when I was working in New Jersey. I had been playing a lot of old arcade games on the MAME arcade emulator.
I had fun playing the original Taito Space Invaders game, but I was frustrated with the inability to shoot more than a single bullet at once with this game. I decided it would be fun to play a modern, 3-D version of Space Invaders with some serious weapons which would allow for massive alien destruction, as it should be.
At first I thought of using my Jax3D engine to render this game, but in the end I decided to learn something new and use OpenGL. I got started by looking at NeHes OpenGL Tutorials and wrote this game in my spare time during April and May of 2005.
Main features:
- Realistic physics simulation
- Challenging and fun gameplay
- Stunning visual effects
- Multiple weapons
- Massive Destruction
- Hidden bonuses
- 20 Waves with over 2,000 invaders
- Both Windows and Linux versions
- Free to Distribute to Anyone!
