You should not use AudioConverterConvertBuffer when you have a sample rate conversion. Use AudioConverterFillBuffer or AudioConverterFillComplexBuffer.

Because in a sample rate conversion the output samples depend on samples before and after them from the input, there is some internal buffering that must happen which requires that you use the pull model of these other conversion routines.

AudioConverterConvertBuffer is only for conversions where there is a 1:1 correspondence between input and output such as bit depth, endian swap, int<->float, (de)interleaving...
