Is it possible to create a buffer channel that stores data (for a certain number of bytes or for a given time) from standard linux tools like cat, dd, etc.?
For example, to collect a certain number of packets, audio data, or something else.
Eg. to create a script delaybufferto do something like this:
arecord | delaybuffer 16000 | aplay
to play recorded sound with a delay of 16,000 bytes.
