samples to milliseconds conversion

Hi,
Is there a calculator or easy math equation that I could use for this? I'm
working at 44.1kHz. Specifically, I'm looking to find out how many msecs is
1030 samples at 44.1kHz.

Thanks,
Frank

 

Rather than kilohertz, think of samples per second. At 44.1 KHz there are:

44,100 samples
--------------
second

You're interested in time per sample rather than samples per time, however,
so you invert:

second
--------------
44,100 samples

Further, you're interested in milliseconds rather than seconds, so:

second 1000 miliseconds
-------------- X ----------------
44,100 samples second

The seconds divide out leaving:

1000 miliseconds
---------------- = 0.0226757 milliseconds per sample
44,100 samples

The time in milliseconds for 1030 samples is therefore:

1030 X 0.0226757 = 23.356009 millisconds

Note that the apparant precision of the result exceeds that of the input
values, so it's better to express the result as 23.356 or perhaps just
23.36 milliseconds.

And you thought you would never use that high school algebra, didn't you!

 

Frank-
one formula you can use:

1000 / (sample rate / number of samples) = milliseconds

for your example: 44100 / 1023 = 43.1085044

1000 / 43.1085044 = 23.19727891 milliseconds

 

If your calculator has a 1/X key, it's simply 44.1 / 1030 followed by the
1/X key.

If there are 44,100 samples in every second, there are 44.1 samples in every
millisecond.

If there are 44.1 samples in every millisecond, how many milliseconds are
in 1030 samples?

Thanks everyone for the help! I'm a drummer, so you can imagine how good my
math skills are ;-)

 

Or, you can forgoe the equations and download the excellent freeware music
calculator, Freequency. I believe the URL is: www.freequency.com

 

Err, I think it's a big mistake to forgo the ability to solve such the
problem. It's well worth the effort to solve that basic one, which
shouldn't be too hard for someone really interested in life with a DAW,
especially after Scott's rephrasing.
