AudioKit buffer to start and stop recording while displaying rolling buffer?

[megastep]

Funny that you mention that, we actually use some of EZAudio internally to implement some of the rolling waveform plots in AudioKit.

[scheung38]

Could you please show me how to add to my project? I like to use EZAudio but it is not written in Swift.

I could not add AudioKit to my project since upgrade to Yosemite as Cocoapods doesn't work anymore

for example:

pod 'EZAudio', '~> 0.0.4'

usr/local/var/rbenv/versions/2.1.5/lib/ruby/site_ruby/2.1.0/rubygems/dependency.rb:315:in to_specs': Could not find 'cocoapods' (>= 0) among 154 total gem(s) (Gem::LoadError) Checked in 'GEM_PATH=/usr/local/rvm/gems/ruby-1.9.3-p194:/usr/local/rvm/gems/ruby-1.9.3-p194@global', executegem envfor more information from /usr/local/var/rbenv/versions/2.1.5/lib/ruby/site_ruby/2.1.0/rubygems/dependency.rb:324:into_spec'

I can't really help you with the CocoaPods issue (that's a Ruby problem). However I would point you to the AudioKitDemo sample project that ships with the library (there's a Swift version), as it uses the rolling waveform plots to show the audio input in the analysis tab.

Tried to build the suggested AudioKitDemo but the libAudioKit iOS Dyamic.a seems to be missing in targets AudioKitDemo -> BuildPhases? as build is successful but nothing shown on my iPhone device? Though from the list I can see and import libAudioKit iOS Static.a?

[megastep]

Make sure to follow the instructions here to set up your project (using the static library is easier) :

https://github.com/audiokit/AudioKit/blob/master/INSTALL-iOS.md

[scheung38]

This also allows microphone input and displays the audio in rolling buffers?

[megastep]

Yes, you should see that in the analysis tab of the app.

[scheung38]

I added AudioKit.xcodeproj into my project, but still cannot see the AudioKit iOS Dynamic? Please advise. Also cannot run the AudioKitDemo which already has this AudioKit.xcodeproj inside?

OK have successfully build the example but nothing shown in device? I mean build was ok but example is not running?

[megastep]

You could try in the simulator first, and obviously you will need some source of audio going on through the microphone to see anything.

[scheung38]

What does it mean when Run -> Success but App not doing anything at all? Both in device or in simulator?

[narner]

When you say 'the app is not doing anything at all', you are referring to the AudioKitDemo, correct?

[scheung38]

Yes the AudioKitDemo can Build, but nothing happens, no errors or warning. But do see that under the AudioKit.xcodeproj -> Products -> libAudioKit OSX.a in red, indicating missing lib? But then the list of Targets visible are AudioKit iOS Static, AudioKit iOS Dynamic and AudioKit OSX? i.e Simply clicking the AudioKitDemo.xcodeproj does not work for me.

Will be great if to get started with the AudioKitDemo

If you need help building the project, I'd be willing to do a screen share. It's pretty straightforward and heavily tested so I bet it is something on your system that wouldn't be too hard to debug.

[scheung38]

Thanks Aure, I do see video demo but it is for Obj C setup?

There are few things I would like, record audio and also accelerometer reading with rolling buffer display and then capture these on a per user basis if possible using Parse.

[aure]

Not much difference for Obj-C or Swift as far as setup is concerned. Does the Objective-C app work for you? Might be a good place to start. You will have to do all this custom coding yourself, don't expect any libraries to do everything for you! :)

How to capture the duration of the audio to begin and end audio capture?

[narner]

Yes, it is possible to do synchronize data with sound. However, the AudioKit Users Group (https://groups.google.com/forum/#!forum/audiokit) is a better place to discuss that, rather then on GitHub.
