    sound.environment = -1
    sound.x = 0

    other_sound.environment = 7
    src << other_sound

Use verb test1() and hear the dry voice. Use verb test2() and hear the clap with reverb. Now keep listening and you'll hear that the reverb has been unexpectedly added to the first sound...

Environment is global; echo is per channel. You'll want to use echo for this.

Oh god =[

Edit: Is there a way to make a few channels not go through global? You don't want ogg music to be affected by the reverb and still be able to use the handy .environment variable for other sound effects.

My sound playground demo should be good for grabbing the parameters you need for an echo list.

Hmm, its not working for me. No matter what I do to the settings in the Sound Playground, the sound sounds the same.

This does not work:

mob/verb/test2()
    var/sound/other_sound = sound('clap.ogg')

    var/list/test = list(1.9,   1.00,   -1000,  -454,   0,  0.40,  0.83, 1.0,  -1646, 0.002,  53,    0.003, 0.250,  0.00,  0.25, 0.000, -5.0,  5000.0,  250.0, 0.0, 100.0, 100.0, 0x3f)
    
    other_sound.echo = test
    
    src << other_sound

If I play that back to back with a non-echo version of the same sound, I hear a difference. It's a little subtle but it's there.

I am not hearing any "echo" or reverb... Only volume differences
