Sample Rate Converter: How Big Is Uncompressed Audio?
Compressed formats hide the maths, but raw audio size is simple arithmetic. This calculator shows it from rate, depth, and time.
What is the Sample Rate Converter?
Uncompressed audio size grows with sample rate, bit depth, channels, and time. Enter those values and this tool calculates the file size in megabytes, which helps when you plan recordings, exports, or storage.
How to use it
- Enter your values in the fields provided.
- Click Calculate Audio Size.
- Read the result and adjust an input if you want a different outcome.
Worked example
Three minutes of stereo 44,100 Hz 16-bit audio is about 31.75 MB uncompressed.
How big is 3 minutes of CD-quality stereo audio?
At 44,100 Hz, 16 bits, and 2 channels, 180 seconds needs 31,752,000 bytes, about 31.75 MB.
