File size = Sample Rate × Bit Depth × Channels × Duration / 8. A 3-minute stereo track at 44,100 Hz and 16-bit: 44100 × 16 × 2 × 180 / 8 = 31,752,000 bytes = 30.28 MB.
| Sample Rate | Bit Depth | Channels | Size per Minute |
|---|---|---|---|

| 48 kHz | 24-bit | Stereo | 16.48 MB |
| 96 kHz | 24-bit | Stereo | 32.96 MB |

The Nyquist frequency is half the sample rate. It defines the highest audio frequency that can be accurately captured. At 44.1 kHz, the Nyquist frequency is 22.05 kHz, which covers the full range of human hearing (20 Hz–20 kHz).
| Sample Rate | Nyquist Freq | Use Case | Common Format |
|---|---|---|---|
| 22.05 kHz | 11.025 kHz | Voice/phone | MP3 (low) |
| 44.1 kHz | 22.05 kHz | CD audio | WAV, FLAC |
| 48 kHz | 24 kHz | Video/broadcast | WAV, AAC |
| 96 kHz | 48 kHz | Studio master | WAV, FLAC |
| 192 kHz | 96 kHz | Archival | WAV |
44.1 kHz is standard for music (CD quality). Use 48 kHz for video projects. Use 96 kHz if you plan heavy processing or pitch shifting. Higher rates use more storage and CPU but offer diminishing audible returns above 48 kHz.
| Sample Rate | Best For | Storage Cost | Audible Benefit |
|---|---|---|---|
| 44.1 kHz | Music, streaming | Lowest | Full hearing range |
| 48 kHz | Video, broadcast | Low | Slightly wider margin |
| 96 kHz | Studio masters | Medium | Processing headroom |
| 192 kHz | Archival only | Very high | No audible benefit |
Bit depth determines dynamic range. 16-bit gives 96 dB (CD standard). 24-bit gives 144 dB (studio standard). 32-bit float gives 1,528 dB of theoretical range with no clipping. Higher bit depth = lower noise floor.
| Bit Depth | Dynamic Range | File Size (vs 16-bit) | Use Case |
|---|---|---|---|
| 16-bit | 96 dB | 1× | CD, streaming |
| 24-bit | 144 dB | 1.5× | Studio recording |
| 32-bit float | 1,528 dB | 2× | Processing, mixing |
Bitrate (bits/sec) = Sample Rate × Bit Depth × Channels. File size = Bitrate × Duration / 8 (to convert bits to bytes). CD audio: 44100 × 16 × 2 = 1,411,200 bps = 1,411 kbps uncompressed.
