* @fileoverview experimental way to play audio in terminals
|
||||
*
|
||||
* This is an stdio application that prints audio samples. The terminal
|
||||
* on the other end, needs to be able to understand the Nf sequences we
|
||||
* use here, which should be invisible to the terminal sort of like out
|
||||
* of band signalling.
|
||||
*
|
||||
* To play audio with a supporting terminal:
|
||||
*
|
||||
* make -j8 o//examples/ttyaudio.com
|
||||
* wget https://justine.lol/numbers.s16
|
||||
* o//examples/ttyaudio.com numbers.s16
|
||||
*
|
