Source A
Move the sliders: the estimate shows when the buffer can no longer cover the pause. All values are illustrative.
A buffer helps keep playback going when incoming data pauses.
Time to audio = response time + time to fill the starting buffer.
After completion: responded → unchecked → timed out. Responding sources are ordered by shorter time to sound, accounting for pauses. Ties preserve the original order.
Rows stay in place during the scan. Results are sorted when it finishes.
Three questions
for one signal.
The player's Radar works with sources added by the user. Here, three steps explain its readings; there is no connection to real stations.
- 01
Did it respond?
Time to the first byte is not yet time to music. A short response time marks the start of data arrival.
- 02
When will sound begin?
The radar model uses a startup threshold of 2 seconds of audio. The source's initial chunk reduces the wait: response + max(0, 2 s − chunk).
- 03
Is the buffer sufficient?
A pause matters to this estimate when it exceeds the startup threshold and initial chunk combined. A short test cannot guarantee steady playback in the future.
