This is the bitrate, which determines the audio quality and file size. At 128 kbps, a stereo MP3 generally uses about 1 MB of storage per minute .

Duration (seconds)=File Size (bits)Bitrate (bits/second)Duration (seconds) equals the fraction with numerator File Size (bits) and denominator Bitrate (bits/second) end-fraction Divide by Bitrate: Final Time:

To find the exact duration, you can use the standard formula for compressed audio:

This is the total file size. Using the "1 MB per minute" rule of thumb, it's clear the file is roughly 3 minutes long. Detailed Calculation

This duration is typical for a or a short podcast segment. Tools like the Audio Duration Calculator can help you perform these conversions for different file types and bitrates.
