Question 1

Is EZAudio still supported for iOS audio projects?

Accepted Answer

No, EZAudio is deprecated and not actively maintained. The author recommends AudioKit for new projects, as stated in the README, due to better support and features.

Question 2

How do I visualize microphone input with EZAudio?

Accepted Answer

Use the EZMicrophone component to capture audio and connect it to an EZAudioPlot or EZAudioPlotGL for real-time waveform updates. The README provides code snippets for delegate methods to update the plot with float arrays.

Question 3

EZAudio or AudioKit: which is better for audio apps?

Accepted Answer

AudioKit is the better choice for most projects because it's actively maintained, supports Swift, and has a broader feature set including synthesis and effects. EZAudio is simpler but deprecated, so it's only suitable for legacy maintenance.

Question 4

Can EZAudio handle recording to different file formats?

Accepted Answer

Yes, EZRecorder supports WAV, AIFF, and M4A formats out-of-the-box, and allows custom formats via AudioStreamBasicDescription. The README shows how to initialize it with client and file formats for recording.

Question 5

How to perform real-time FFT with EZAudio?

Accepted Answer

EZAudio includes an FFT example using the Accelerate framework with EZMicrophone. You can capture audio data and compute FFT in delegate callbacks, then visualize it with plots, as demonstrated in the EZAudioFFTExample.

Question 6

Does EZAudio work with Swift projects?

Accepted Answer

Yes, but it requires Objective-C bridging since it's written in Objective-C. You can use it in Swift, but the API may feel outdated compared to native Swift frameworks like AudioKit.

Question 7

What are the performance trade-offs of EZAudioPlot vs EZAudioPlotGL?

Accepted Answer

EZAudioPlotGL uses OpenGL for GPU-accelerated drawing and handles more points efficiently, ideal for high-performance visualizations. EZAudioPlot uses Core Graphics and may choke on large buffers, as noted in the README for plots over 1024 points.
