What is Audio File Size?

An audio file size refers to the amount of digital storage space required to save a particular audio file. It is typically measured in kilobytes (KB), megabytes (MB), or gigabytes (GB). The size of an audio file depends on several factors including its length, bit rate, and the audio format. Higher bit rates and longer durations result in larger file sizes. Reducing the bit rate or compressing the file can decrease the size, but may also reduce the audio quality.

Example Calculation

Let's assume the following values:

Using the formula:

\[ FS = \frac{128000 \times 300}{8} = 4800000 \text{ bytes} \approx 4.8 \text{ MB} \]

The file size is approximately 4.8 MB.
