Live.c Example not working #313

Closed roccopersico99 closed 1 year ago

roccopersico99 commented 1 year ago

I am unable to get the live.c example working, and I believe it boils down to an issue with sox. From my understanding, live.c uses sox to take audio input from the default audio device, converts it to a raw format, and sends it to stdout, which is then piped into the FILE* sox ptr and used to fill the frame buffer, which is then given to the endpointer for processing and finally a hypothesis phrase can be obtained. From my research, it appears that output piping in sox is broken for 14.0.x versions but works fine in 13.0.x versions (https://stackoverflow.com/questions/30166384/sox-piping-output-in-windows). However, sox 13.0.x versions do not appear to support using audio devices as input (no -d option) so live.c is not possible with either version of sox. Please let me know if I'm misunderstanding or just missing something entirely here, thanks!

Hm, it works for me with v14.4.2 on Ubuntu 22.04.

If you modify the code to simply read from stdin, and pipe a raw audio file to it, does it still fail to work?

Also, it's entirely likely that it just doesn't work on Windows, because lots of things don't...
