How accurate is the Audio File Size Calculator for compressed formats like MP3?

The tool provides estimates based on the input parameters; actual MP3 file sizes depend on the specific bitrate chosen during encoding, which may differ from the calculator's uncompressed calculations.

Can I use this calculator to determine the size of a stereo WAV file?

Yes, by selecting 16-bit depth, 44.1 kHz sample rate, and 2 channels (stereo), the calculator will estimate the file size for a standard CD-quality WAV audio file.

What sample rate should I choose for high-resolution audio?

For high-resolution audio, common sample rates include 96 kHz, 192 kHz, or 352.8 kHz; the calculator supports these and higher rates to estimate the resulting larger file sizes.

Is there a limit to the duration I can enter for the calculation?

The calculator accepts duration in hours, minutes, and seconds; very long recordings will produce proportionally larger file size estimates, but there is no stated hard limit on the input length.

About this tool

What Audio File Size Calculator does

The Audio File Size Calculator on Omni Calculator estimates the storage space required for a digital audio file based on its technical parameters. Users input duration, sample rate, bit depth, and channel count to receive a file size result, with support for both uncompressed formats (like WAV) and common compressed formats (MP3, AAC, FLAC). Beyond the calculator, the site provides educational context explaining digital audio concepts, bit depth, sample rates, and the underlying calculation formula, helping users understand how audio files work. Results can be shared via a link, and the interface allows switching between multiple units of measurement.

Step by step

How to use the Omni Calculator Audio File Size Calculator

1
Select the desired bit depth from the dropdown menu (e.g., 16-bit for CD quality, 24-bit for professional recording)
2
Choose the sample rate from the available options (e.g., 44.1 kHz, 48 kHz, 96 kHz)
3
Pick the number of channels (mono, stereo, or multi-channel configurations)
4
Enter the audio length in hours, minutes, and seconds to calculate the estimated file size
