Hello, does anybody know about any programs to create really good sound effects?
You could buy FL studio 20 to create sound effects and watch their tutorials on YouTube.
Depends on what you mean by make really good? Good sound design is an art and set of skills that many take years to master. Unless you want to go that road, why not use someone else's.
FL Studio, Reason and Logic are all awesome programs for music.
Best of luck with it all!
Depends on the types of sounds you're trying to make. Electronic sounds will probably start with synthesized material, so you'd need software capable of synthesis - and there's different approaches here including AM and FM synthesis, and either true analog or digitally modelled analog. Formant synthesis as well. There are other models, but they aren't coming to mind. PCM Synths start with sampled wavs (recordings) and filter those.
Naturalistic sounds start with recordings. You'll need a decent recorder. These days we all have smartphones, so a decent add on phone mic can get you there.
After that it's all about the mangling. There are dozens of programs to mangle noises. You'll want to be able to pitch and time shift, compress, reverb, and all kinds of other effects.
Audacity is a good free choice. Others have brought up other software. I use the Vegas Pro/Sound Forge combo.
Really a lot of sound design starts with being creative with recording. But this is a huge, huge topic.
As some examples we'll look at Star Wars. The blasters started with recordings of a hammer hitting a support cable for a light pole. Star Destroyer engines came from a recording of the air conditioner in a hotel room Ben Burtt stayed in, and the Falcon starts with recordings of WWII bombers at an air show. Lightsaber sounds?
