Cutting ambient_generic sounds short

[Mess]

Hello,

I am using ambient_generics to create atmosphere in my single player map and am using the HL2 music files. However I only want to play the first 20 seconds or so and then have the sound fade out. However I cannot get it to do this.

Does anyone have any ideas?

Edit - I added an output to my trigger that my sound 'TurnOff' after a delay of 20, and I gave the ambient_generic a spin off time, but this didn't work. The music played all the way through.

If it's for a mod, just chop the sound at 20 seconds, so you fade it out in your editing program and then just use the sound with a play once.

I was afraid I'd have to do that. Any suggestions for what programs I can edit the mp3s with then?

If you're looking for something professional I'd go with Cubase SX

I used a nifty program called WavePad. Worked a treat.
