iphone - Adjust the length of an AudioUnit Buffer - Stack ...
https://stackoverflow.com/questions/4863330/adjust-the-length-of-an-audiounit-buffer
There is no problem in defining and initializing an AudioSession with the RemoteIO Audio-Unit, and that's the way to set the desired buffer length. I have some code doing exactly this, but it will take me a few hours till I get back home and can post it.
The Audio Unit - Apple Developer

The Audio Unit. When you develop an audio unit, you begin with the part that performs the audio work. This part exists within the MacOS folder inside the audio unit bundle as shown in Figure 1-2.You can optionally add a custom user interface, or view, as described in the next chapter, The Audio Unit View. In this chapter you learn about the architecture and …
Audio Buffer Latency - Unity Forum
https://forum.unity.com/threads/audio-buffer-latency.56867/
We've got our own audio unit initialized using sample code from Apple, though the very first step seems to have already been done by Unity3D. It's supposed to be able to let us set a preferred latency value. However, no matter what I do the input audio buffer is always 4096 frames, which is a latency of 85ms at a 48000 Hz sample rate.

But the audio format I'm setting on the AudioUnit has 8k rate, and here is my callback being called: (lldb) po frameCount 64 Let's do the math. 16000 * 0.008 = 128. This is the expected number of frames with the system buffer duration and 16k sample rate.
Writing an Audio Unit v3: Instrument | Gene De Lisa
https://www.rockhoppertech.com/blog/writing-an-audio-unit-v3-instrument/
Audio Units have been around a loooong time. But version 3 is fairly recent (2015). The API in v3 is quite a bit different from v2, but much of v2 is still lurking in the closet. Also, if you have a v2 audio unit, Apple supplies a way to “bridge” to v3. There is not much documentation on it though. It’s the Apple Way!

Create a FFT Analyzer part II: designing our spectral ...
http://sample-hold.github.io/2011/11/23/create-a-fft-analyzer-part-ii-designing-our-spectral-processor/
Audio Units generally capture N input samples each time they are rendered, N being set by the host in which they operate. N has a value usually lower than the minimum number of frames required for computing FFT, so before we can provide at least 1024 samples to FFT, we have those N samples stored into a ring buffer over a few cycles.
