Sample Rate Storage Calculator

Calculate uncompressed audio storage needs by sample rate.

Uncompressed Size

Plan storage for recording sessions.

What this calculator does

This calculator helps you compare storage requirements across different sample rates and bit depths, essential for planning recording sessions and managing studio storage infrastructure. By showing side-by-side comparisons, it illustrates how doubling sample rate quadruples storage needs (due to 2 samples per second × 2 channels), while changing bit depth linearly scales file size. Understanding these relationships helps you make informed decisions about equipment investments, cloud storage needs, and archival strategies.

How it works

The calculator generates a matrix comparing uncompressed file sizes for multiple sample rate and bit depth combinations over a specified duration. It applies the formula: File Size = (Sample Rate × Bit Depth × Duration × Channels) ÷ 8 bits per byte. The comparison reveals proportional relationships—jumping from 44.1 kHz to 96 kHz doubles storage needs twice over, while upgrading 16-bit to 24-bit increases size by 50%.

Formula

For each combination: Size (MB) = (SR Hz × BD bits × Sec × Channels) ÷ 8,000,000. Create a table with all combinations to visualize cumulative effects.

Tips for using this calculator

  • Use this tool to estimate total storage needed before starting a multi-track session
  • Cloud backup costs scale with these calculations—higher rates mean higher monthly expenses
  • Consider that most mixing happens at 48 kHz—16-bit recording requires less storage with minimal quality sacrifice
  • Plan for at least 2-3× calculated size as buffer for exports, backups, and intermediate files
  • Stereo projects require double the storage of mono; multiply storage calculations accordingly

Frequently asked questions

How much storage do I need for a typical album recording session?

A 10-song album with average 4-minute tracks recorded at 48 kHz/24-bit stereo needs roughly 170 MB uncompressed. However, budget for 500 MB to 1 GB accounting for multiple takes, stems, and backups. If recording at 96 kHz, triple that estimate.

Why does sample rate have a bigger impact on file size than bit depth?

Sample rate affects file size linearly in the direct calculation, but because doubling sample rate means twice as many samples per second, and you have two channels in stereo, the practical impact is significant. Bit depth changes only the bits per sample, which is a smaller multiplier.

Can I mix different sample rates in the same session?

Technically possible but not recommended. Modern DAWs handle sample rate conversion, but it consumes CPU and can introduce artifacts. Best practice is to record everything at your session's native sample rate, usually 48 kHz for most work.

How much does lossy compression reduce file sizes?

Lossy compression (MP3, AAC) typically reduces files by 85-90% compared to uncompressed audio. A 170 MB uncompressed album becomes 15-25 MB as MP3s. Lossless formats like FLAC achieve 30-50% reduction while preserving all original data.
