naudio 32bit ieee float to 24bit

Question

In NAudio I need to play a WAV file with an ASIO driver that only accepts 24bit audio. The wave stream is stored in a wav file, but it is 32bit ieee float. I need to convert the stream from 32bit to 24bit. I tried all the NAudio conversion functions but no one is good for my purpose.

Answer 1

ASIO has a bunch of different ways it can receive 24 bit audio (big endian or little endian, 3 bytes or 4 bytes per sample), and NAudio doesn't have converters for all of them. The AsioSampleConverter class contains converters for the most commonly used formats, so you possibly adapt one of the built in converters to your use case.
