Dynamic Sound

Reupload of an old addon. Been looking for it for years after it was removed but fortunately I found it within some old gmod files. Use this at your own risk as it can be buggy, but it's fun to experiment and play around with nonetheless. It would be great for someone to pick this up and refine it into a more usable addon.

Highly recommend binding "snd_restart" to a key for when audio bugs out.

Original description:

This add-on overrides GMod's Lua's sound library and the EmitSound for entities and provides sound that travels, adding a delay effect. This can be provide neat audio effects with the Fireworks addon, or SWEPS. There are some limitations because of how addons work in GMod. Only addons that utilize the sound library in GMOD's Lua will have the traveling sound delay. Explosions made from barrels, and other physical props will be heard instantly.

This add-on also provides the Doppler effect for sounds. When an object is emitting sound and is approaching a listener, the pitch of the sound will be higher, and if an object is moving away, the pitch of the sound will be lower.

To turn off dynamic sound temporarily, change the console variable "dyn_sound" to 0 (Default: 1[On])
To turn off the doppler effect temporarily, change the console variable "dyn_sound_doppler" to 0 (Default: 1[On])

To change how fast sound travels, change the console variable "dyn_sound_speed" (Default: 8932[8,932]). (The speed of sound in Source units divided by two)

To increase the range of sounds, change the console variable "dyn_sound_lvlscale" (Default: 1)
2 would be two times the range
.5 would be half the range

Please note that sound travels to the player before it is heard. If you want to use cameras, use the "Ear" tool and left click the camera. This will make sound travel to the camera before it is heard.

A useful command to know is "stopsounds", there will be times where sounds still play even when the entity is removed, if that happens "stopsounds" will stop that sound, and all other sounds playing too.

LIMITATIONS:
Entities that are found in the Source engine. (FIXED)
Nuke Pack 4 calls surface.PlaySound(), that basically means the sound plays at the player's position, thus sound is heard instantly.

BUGS:
On Servers, shared sounds play twice, the only way to fix it is to ask the developer of that add-on to emit the sound server or client-side. This is a minor problem and you should be able to cope with it."
