Hi there,

I've noticed that the variable_record_ms and variable_record_seconds values
are often inaccurate. Is there any explanation for this?

The example below shows that while the RECORD_START and RECORD_STOP events
were about 4 seconds apart, the variables claim that the file is 7 seconds
long. See the soxi output at the end, which shows that the length of the
file is 00:00:03.50, thus more in line with what the event timestamps
suggest.
