What to enter
| Input | Meaning and units |
|---|---|
| Sample rate (samples/s) | Enter sample rate in samples/s; use the same basis as the other measurements. |
| Bits per sample (bit) | Enter bits per sample in bit; use the same basis as the other measurements. |
| Channels (count) | Enter channels in count; use the same basis as the other measurements. |
| Duration (s) | Enter duration in s; use the same basis as the other measurements. |
Understanding your result
Read Audio data size (byte) in the units and model stated on this page. The formula bytes=rate*bits*channels*seconds/8 defines the relationship; measurement accuracy and model applicability are separate from numerical precision.
Common mistakes
- Mixing input units or changing the physical meaning of a variable without changing the model.
Check your calculation
- Use the worked example as a known reference case, then change one input at a time and check the direction and units of the response.
