Efectos de audio en un track

[edumonbus]

Hola a tod@s de nuevo!

Quisiera saber esta vez si en un solo track de audio de pueden aplicar diversos filtros y efectos sin tener que crear pistas "paralelas" con esos efectos aplicados. Creo que me he explicado pero si no es así, decídmelo, por favor. Gracias de antemano

Yes, effects can be applied to a single track. Audition's multitrack mode doesn't actually require you to use more than one track. (Well, I guess in a way it does: your single track and the mix track.) Hope I've understood you.

Lo que yo quiero decir es que en una sola pista se pueden aplicar efectos o filtros solamente en ciertas partes del track, no a todo el track en general. 
Si la pista empieza con su sonido original en el minuto 00,0' y, por ejemplo, a partir del minuto 2,00' quiero aplicar 0,20' de filtro para luego volver al sonido original, ¿eso es posible?
Gracias
What I mean is that on a single track, you can apply effects or filters only to certain parts of the track, not to the entire track in general.
If the track starts with its original sound at minute 00:00 and, for example, starting at minute 2:00, I want to apply a 0:20 filter and then return to the original sound, is that possible?
Thank you!

Two ways to do that: if you want the effect simply on for a portion, then off, the easiest way is to use the razor tool to cut the track into clips, and apply the effect to the clip rather than the track. See this page.

If you want to fade an effect in and out , or vary its strength, you can use automation to adjust the the effect over time, moving from "wet" (effect applied 100%) to "dry" (0%—no audible process). See this page.
