I appoligize for not sure where to ask this question, thus posting it here. I want to learn to edit audio, mainly adding special effects to verious audio clips. (e.g. remove noise, add noise, echos, make the sound sounds like in a large concert hall, cannon, small room, over the phone quality, radio or other situations.) What software do you recommend? Easy and cost efficient. I have Magix Audio Cleaning Lab, but there is not much discussion on how to use it. The manual does not give you much. Thanks in advance.
If want to learn to edit audio, then you should learn on a ProTools system. It is, IMO, the best audio editing software available. Some of the other DAWs excel in other areas, but I think ProTools is the editing tool of choice. Besides that, it's the most popular software and the most accessible in studios around the world. So if you're going to learn, you might as well learn the system that might lead you to work in the future.
If you are wanting to learn how to add reverb, delays and other effects then you need something that has lots of good sounding plug-ins. While ProTools is great, some of the Digi plug-ins aren't. You have to buy 3rd party plug-ins to get great sounding reverbs, EQs and such. You can certainly learn with Digi's plugs, but I would upgrade eventually.
On the super cheap side, try Audacity. It's free, cross-platform audio recording and editing software.
