Formula
samples = duration × sample rate= 7938000
Note
This result is a simplified model: it applies the displayed standard formula to the values you entered, assuming twelve-tone equal temperament, a speed of sound of 343 m/s in dry air at 20 °C, an ideal free field with no reflections or air absorption, purely resistive speaker loads and Sabine's diffuse-field assumption. Real rooms, instruments, codecs and amplifiers depart from these idealisations, so measure with proper instruments for critical work.

How is the number of audio samples calculated?+
Sample count equals duration in seconds multiplied by the sample rate in Hz, since sample rate is literally defined as the number of samples captured or played back per second. Three seconds of audio at 44,100 Hz contains 132,300 samples.
Why does sample rate matter for audio quality?+
The sample rate sets the highest frequency that can be accurately captured, per the Nyquist theorem, at just under half the sample rate, so 44.1 kHz can represent frequencies up to about 22 kHz, covering the full range of human hearing. Higher rates like 96 kHz or 192 kHz capture more headroom above audible range, mainly useful for processing flexibility rather than audible improvement.
Why is 44,100 Hz such a common sample rate?+
44.1 kHz was chosen for CD audio because it comfortably exceeds twice the upper limit of human hearing (about 20 kHz) while keeping file sizes and processing loads reasonable for the technology of the era. It remains a standard default in music production even though other rates like 48 kHz (common in video) are equally valid.
Does sample count relate to file size?+
Yes, sample count directly drives file size: more samples per second, more bit depth per sample, and more channels (mono vs stereo) all multiply together to determine the raw data size of uncompressed audio. Doubling the sample rate roughly doubles the file size for the same duration.
Why would I need to know the exact sample count rather than just the duration?+
Precise sample counts matter for tasks like sample-accurate editing, loop point placement, or programming audio buffers in software, where being off by even a handful of samples can cause audible clicks or timing errors. Duration in seconds alone isn't precise enough for this kind of technical work.
