How to use this calculator
Estimate uncompressed PCM audio size for WAV-style production and storage planning.
How the calculation works
- Enter duration.
- Choose sample rate, bit depth, and channel count.
- The tool estimates raw PCM bytes.
Formula
PCM bytes = duration seconds x sample rate x bit depth / 8 x channels.
Example
One minute of stereo 44.1 kHz 16-bit PCM is about 10.1 MB.
Understanding your result
Use the output as a practical starting point, then review it before using it in an important workflow.
Assumptions and limitations
- Compressed formats such as MP3 or AAC use different bitrate math.
- Headers and metadata add a small amount of overhead.
