Audio Size Calculator
Convert data storage units with this free audio size calculator. Perfect for computing and digital storage calculations.

What Audio Size Calculator does
The Audio Size Calculator on Number Convert estimates the storage size of uncompressed audio files, specifically PCM/WAV formats. Users input sample rate, bit depth, number of channels, and desired duration to determine the resulting file size. The tool also handles general data storage unit conversions between kilobytes, megabytes, gigabytes, and terabytes, correctly applying the binary standard of 1 KB = 1024 bytes. It is designed to help audio engineers, podcasters, and musicians verify whether project assets will fit within required storage limits or platform restrictions.
How to use the Number Convert Audio Size Calculator
- 1
Enter the sample rate (e.g., 44100 Hz) for the audio project
- 2
Set the bit depth (e.g., 16-bit or 24-bit)
- 3
Select the number of channels (mono or stereo)
- 4
Input the desired duration in minutes or seconds
- 5
View the calculated total estimated file size in the chosen storage unit
Best for

Audio Size Calculator FAQ
- How accurate is the Audio Size Calculator for real-world files?
- The calculator provides estimates based on uncompressed PCM/WAV parameters; actual file sizes may vary depending on compression, metadata, and specific encoding methods used.
- Can this tool calculate sizes for MP3 or other compressed audio?
- While the tool handles general data storage unit conversions, its primary design focuses on uncompressed audio specifications; for compressed formats, users may need to input bitrate values or use a dedicated bitrate calculator.
- What storage units does the calculator convert between?
- The tool converts between Kilobytes (KB), Megabytes (MB), Gigabytes (GB), and Terabytes (TB), applying the binary standard where 1 KB equals 1024 bytes.
- Is the calculator useful for planning podcast episode sizes?
- Yes, audio creators can input duration, sample rate, bit depth, and channels to estimate whether a podcast episode will fit within specific storage or attachment limits, such as a 25MB email limit.
