Question 1

How do I set up audio recording with Novocaine on iOS?

Accepted Answer

Create a Novocaine instance, set an input block to handle microphone data, and call play. The README provides a concise code snippet for capturing audio in interleaved format with minimal setup.

Question 2

Novocaine vs AudioKit: which is better for iOS audio?

Accepted Answer

Novocaine is lighter and more focused on simple, high-performance audio I/O with minimal code, ideal for basic capture/playback. AudioKit offers a broader feature set for synthesis and effects, better for complex audio apps.

Question 3

Does Novocaine work with Swift?

Accepted Answer

Yes, but it requires Objective-C bridging since it's written in Objective-C and C++. You'll need to handle file extensions and interoperability, which can add complexity to Swift projects.

Question 4

How to reduce latency in Novocaine audio processing?

Accepted Answer

Novocaine uses a C++ RingBuffer for low-latency performance. Ensure proper buffer sizes and avoid heavy processing in callbacks to maintain real-time responsiveness, as hinted in the high-performance focus.

Question 5

Can I use Novocaine for real-time audio effects like reverb?

Accepted Answer

Yes, by processing audio in the input or output blocks. However, for advanced effects, you might need additional DSP libraries, as Novocaine focuses on I/O abstraction rather than built-in effects.

Question 6

Why do I need headphones for play-through examples?

Accepted Answer

The README warns that without headphones, microphone and speaker proximity can cause feedback. This is a practical audio issue, not a library flaw, but it highlights real-world usage considerations.
