[Freeswitch-users] enable_file_write_buffering

[Tamas Jalsovszky]

Thank you.
Example case: stereo recording, 8kHz, default buffer size (65536)
65536/2 channels/2 bytes perc channel/8000 samples per second -> 2,048
seconds.
Is this a correct calculus?

As I have seen, there is a buffering in media bug too, where the default
number of frames is 25, which would mean in my case with 20ms codec, 500ms
buffer. Does this adds to the one previously calculated meaning the actual
buffering is about 2.5 seconds?
