オーディオアプリ開発でありがちな4つの間違い | POSTD
ここで論じているのは、オーディオアプリの開発者が陥りがちな 4つの間違い 、 より良く開発する方法 、 問題個所の発見方法 です。主に開発者向けの内容ですが、開発者以外の方にも知っておいてもらいたいと思います。ここでは、開発者向けの診断ツールである Realtime Watchdog を紹介し、 人気のあるオーディオライブラリの調査結果 を提示します。 オーディオアプリの開発はとてつもなく楽しいです。やりがいを感じるし、創造力を発揮できる範囲が大きく広がり、ひとたび開発が終われば、 誰かがクリエイティブなツールとして使ってくれるのです！ こんな分野は多くないし、この領域で働けるなんて非常に幸運だと自分でも思っています。 しかし、仕事でオーディオアプリを扱う時には深く考えなければならない部分もあります。オーディオアプリの開発者としてユーザに対する責任があるのです。大前提として、ユーザを公共の
GitHub - syedhali/EZAudio: An iOS and macOS audio visualization framework built upon Core Audio useful for anyone doing real-time, low-latency audio processing and visualizations.
Awesome Components I've designed six audio components and two interface components to allow you to immediately get your hands dirty recording, playing, and visualizing audio data. These components simply plug into each other and build on top of the high-performance, low-latency AudioUnits API and give you an easy to use API written in Objective-C instead of pure C. EZAudioDevice A useful class for
Core Audio in iOS 6 (CocoaConf Portland, Oct. '12)
Core Audio in iOS 6 provides frameworks for low-level audio processing including capture, playback, and effects. It includes engines like Audio Units for real-time processing and Audio Queue for simpler playback and recording. Helpers handle file and stream I/O, format conversion, and audio session management. New features in iOS 6 include the AUNewTimePitch unit for independent pitch and time shi
The Amazing Audio Engine
GitHub CocoaPods Retiring The Amazing Audio Engine It's with regret that I've decided to announce the retirement of The Amazing Audio Engine. TAAE has had a great run. However, the time demands of supporting the developer community have become unsustainable for me, especially with the demands of Loopy 3 (aka Loopy Masterpiece Edition) and imminent new fatherhood! Here's the good news, though: 99%
[Deprecated] Swift and Current Limitations of Audio Unit Implementations
[Deprecated] Swift and Current Limitations of Audio Unit Implementations June 16, 2014 UPDATE (07/31/2014): Apple has since modified pointer usage, which might allow for the use of user-provided callbacks in CoreAudio. I have been up to my neck in dissertation work, so I have not been able to test this. Good luck! Swift currently (June 16, 2014) is less capable than Objective-C for real-time audio
LiveCoding with Swift Audio continued...
After getting stuck trying out Swift Playgrounds using the new AVFoundation classes because I was on Mavericks the temptation was too much at the weekend and I created a new partition, downloaded the latest Yosemite build and got started. Jamie Bullock's Live coding audio with Swift playgrounds worked like a dream and I was up and running with some playground code making sounds. Great. Googling a
Swift and Core Audio | Gene De Lisa
Like many of you, I’ve been knee deep into Swift this week. Once you get beyond the hello world things and try something a bit more complicated, you start to learn the language. So, why not go off the deep end and try to work with what is essentially a C library: Core Audio? Turns out that’s a good way to get the types grokked. First, don’t try to use core audio in a Swift playground. I wasted a d

Playing User Audio with iOS
I don’t write here anymore. You can now find me at coderchrismills.com. A few months back someone asked me show them how to play audio from a users music library on iOS. I took this opportunity to demo music analysis program that covers a few things in one project. How to use blocks and NSOperationQueue to load data How to use MPMediaPickerController Simple audio analysis with vDSP I was really ho
WaveForm on IOS
Thank all. I found this example here: Drawing waveform with AVAssetReader , changed it and developed a new class based on. This class returns UIImageView. //.h file #import <UIKit/UIKit.h> @interface WaveformImageVew : UIImageView{ } -(id)initWithUrl:(NSURL*)url; - (NSData *) renderPNGAudioPictogramLogForAssett:(AVURLAsset *)songAsset; @end //.m file #import "WaveformImageVew.h" #define absX(x) (x

From iPhone Media Library to PCM Samples in Dozens of Confounding, Potentially Lossy Steps iPhone SDK 3.0 provided limited access to the iPod Music Library on the device, allowing third party apps to search for songs (and podcasts and audiobooks, but not video), inspect the metadata, and play items, either independently or in concert with the built-in media player application. But it didn’t provid
