Iphone app for music frequency bars visualizer thing?
I'm looking for an app for this.
I don't know the exact name of it which is maybe why i can't find one. What I'm trying to describe is that thing you see on a dj's laptop screen, or an audio interface that has a screen, it looks like a bar graph, where x is frequency and y is volume, but it moves to the music. It's not an eq screen, but it looks like it. I can't for the life of me remember what it's called. I think the technical name is "real time spectrum analyzer" but i know there's another (more casual) name for it. Also i really want to find an app that will play your music and show this as a visualizer.
I've been trying to work off of the Speak Here code but it's horribly outdated (latest build was when iPhone OS 2 was out!) and some of the old code actually throws warnings. I would bet that a lot of what they were doing could be accomplished with core graphics/animation. It seems crazy that I'm unable to find even one tutorial about making a visualizer for AVAudioPlayer (or any core audio framework).
- Why does my iPhone 4 have no signal yet has full bars? My phone is on EE and doesn't connect to the internet even though i have full 3g does anyone know why? I've tried resetting it everything and nothing seems to work it does this for about 3 hours a day?
- Sprint Iphone 4 goes from 5 bars to No service and Searching? I called sprint and they tried everything on their end and told me to reset the network settings, even resetting the entire phone, and nothing helped. I read somewhere that the antenna is touchy on these phones and wearing a case may help? I would like to hear any fixes and if anyone else has had these issues. It worked completely fine the first day I had it and then it just started losing service for no reason.
