How the audio calculator works
Compressed audio size is estimated from bitrate: size = bitrate × duration. Drop a file to read the browser-reported duration and compare actual size to estimated bitrate.
Questions
Are audio files uploaded?
No. Files are opened as local object URLs in your browser.
Why is actual size different?
Variable bitrate, metadata and container overhead can make real files smaller or larger than the estimate.
Can it calculate storage for many files?
Yes. Set the file count to estimate total storage for episodes, albums or batches.
