I'm trying to use GarageBand to create some short notification sounds to use in software I'm writing. Unfortunately my musical skills are non existent and I'm struggling to create anything that sounds good. I'm attempting to create some short sounds with only a few notes. For example if you are an iPhone user you can go to Settings > Sounds & Haptics > Choose something like AirDrop or Text Tone and play some of the sounds under the
Alert Tones section. These are the type of thing I'm trying to create.
If you take Apple's 'Note' alert tone as an example. It's just a "ping" sound which fades out over time. I've seen tutorials about using automation to fade the audio out over a time period, but I can't create a ping sound to begin with. Or under the Classic alert tones there's one called Ding. This is very similar to the Ping but with a different sound. I wouldn't mind trying to create something which sounds similar to that but maybe with a low note followed by a high note.
Everything I try to create just sounds like two notes on the selected instrument, I don't know how to adjust/tweak the sounds to make them sound how I want. I know with an electric guitar a synthesiser can be used to adjust how it sounds, which in my mind is kind of what I'm trying to do here. I've tried searching for tutorials but everything I find for GarageBand is just showing how to create music tracks (which after all, is what it's for). Is somebody please able to explain how I can do this in GarageBand (if it's possible), or tell me if there is any other free software which would allow me to do this and allow me to distribute the audio files I create with my open source application? (I can use a Mac or Windows)
I hope this makes sense. I don't know the correct terminology to explain this any better.
