Added stdin/stdout backend #56
Conversation
…ndfile doesn't like the stdout file descriptor, atm.
…ves the same output as sa-sndfile raw, except there's 4000 00s at the end of it??? Also, rx isn't doing anything for some reason.

Hi, I was trying to compile minimodem for wasm and your PR came in handy. Thank you. I'm not otherwise affiliated with this project. Just adding a few comments on stuff I found.
It'd be nice if this error message could be rewritten to so only --file and --stdio modes are available or something and come with an additional check to not be tripped in for stdio mode.

There's a --float-samples command line flag. Instead of forcing the value here, couldn't you rely on that flag?

+1 having stdin. Especially for soundcard-free hardware. I'm using this to process input from an rtl sdr (with sox piped inline to deal with the floating-point conversion) |

This PR is very helpful -- I've been working on getting minimodem hooked up to a PBX (telephone exchange) for a communications museum. This will allow old Telex/RTTY terminals to call into a number and then receive automatic service (through minimodem). |
I'm trying to virtualize minimodem as a Java library via NestedVM, and it seemed like it'd work best if it could operate on stdin/stdout, so I added a simpleaudio-stdio backend. You enable it with -O or --stdio. Lemme know if I messed something up, or if you actively don't want this feature, or something.
