Only know that dont understand nothing ^^

Hi, I am converting audio between NTSC and FILM and I noticed that the final result, in duration, is distinctive to the expected one.

For example, starting with an audio of the following characteristics:

Duration: 24 min 37 sec 684 ms
Origin: NTSC
Samplerate: 96000 Hz
Bitdepth: 32 float

The conversion factor gives me a samplerate change of 95904.096.

When truncating this amount, in audition change the sampling rate to 95904 and the result is an audio with the following duration: 24 min 39 sec 163 ms

If I use the amount 95905, I get: 24 min 39 sec 147 ms which is approximated to that obtained with eac3to being 146 ms.

I can understand that we are using a multiplo of 5, for reasons that I do not understand, since I have made a conversion table, and this is the only conversion along with PAL to FILM, which disagree with the operations made from another editor. In the latter case, the conversion factor is 92067,932, which must be rounded to 92068 to obtain the expected value. This rounding I can understand but the previous one seems to me that rounding to 95905 is too much.
