Audio File Size Calculator

Formula

To calculate the audio file size:

\[ FS = \frac{BR \times D}{8} \]

Where:

\(FS\) is the File Size (bytes)
\(BR\) is the Bit Rate (bps)
\(D\) is the Duration (seconds)

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:

Bit Rate (\(BR\)) = 128000 bps
Duration (\(D\)) = 300 seconds

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.
