MISRC Extract is a simple tool to de-interleave ADC channels and the AUX data from a raw .bin capture.

The MISRC captures with 2 ADC channels 12-bit and the 8-bit AUX data is interleaved into 32 bit words, so you end up with a 32-bit .bin file if no real-time extraction is used.

This tool de-interleaves that data For x86_64 (64-bit AMD and Intel processors).

There is handwritten assembly for higher performance using SSE instructions.

capture.bin --> misrc_extract --> Channel_1.s16, Channel_2.s16

Aux Data mode is not yet in use due to lack of sub-boards like audio etc.

-i Input file (use '-' to read from stdin)

-a ADC A output file (use '-' to write on stdout)

-b ADC B output file (use '-' to write on stdout)

-x AUX output file (use '-' to write on stdout)

-p pad lower 4 bits of 16 bit output with 0 instead of upper 4

-s input is captured as single channel (-b cannot be used)

Inside the directory of capture run:

misrc_extract -i misrc_capture.bin -a channel_1.s16 -b channel_2.s16
