Size = 320 * 1000 * 180 / 8 / (1024 * 1024) = 6.87 MB. The calculator shows 7.03 MB accounting for rounding and metadata overhead.

Size = 1411 * 1000 * 2700 / 8 / (1024 * 1024) = 453.94 MB raw; FLAC compression typically reduces this by 30-50%, but theoretical max bitrate is used here.

Per episode: 128 * 1000 * 3600 / 8 / (1024 * 1024) = 54.93 MB. 10 episodes total about 549.3 MB.
File size in MB = (bitrate in kbps * duration in seconds) / 8 / 1024. A 3-minute MP3 at 320 kbps: 320 * 180 / 8 / 1024 = 7.03 MB. For lossless formats like FLAC at CD quality (1411 kbps), the same track would be about 31 MB.
| Format | Bitrate | 3 min Song | 1 hour Album |
|---|---|---|---|
| MP3 128 | 128 kbps | 2.81 MB | 56.3 MB |
| MP3 320 | 320 kbps | 7.03 MB | 140.6 MB |
| AAC 256 | 256 kbps | 5.63 MB | 112.5 MB |
| FLAC CD | ~1411 kbps | 31.0 MB | 620 MB |
| WAV CD | 1411 kbps | 31.0 MB | 620 MB |
For most listeners, 256 kbps AAC or 320 kbps MP3 is transparent (indistinguishable from lossless in blind tests). Audiophiles prefer FLAC (lossless) for archival quality. Streaming services use 128-320 kbps lossy for mobile and up to 1411 kbps lossless for premium tiers.
| Use Case | Recommended Format | Bitrate | Quality |
|---|---|---|---|
| Podcasts | AAC | 64-128 kbps | Good |
| Casual music | MP3/AAC | 192-256 kbps | Very Good |
| Critical listening | MP3/AAC | 320 kbps | Excellent |
| Archival | FLAC | ~1000 kbps | Lossless |
| Hi-Res | FLAC 24-bit | ~4600 kbps | Studio quality |
At 320 kbps MP3 with an average song length of 3.5 minutes, 16 GB holds about 2,000 songs. At 128 kbps you can fit around 5,000 songs. With lossless FLAC, expect roughly 450 songs. Storage needs scale linearly with bitrate.
| Storage | 128 kbps MP3 | 320 kbps MP3 | FLAC CD |
|---|---|---|---|
| 1 GB | 312 songs | 125 songs | 28 songs |
| 16 GB | 5,000 songs | 2,000 songs | 450 songs |
| 64 GB | 20,000 songs | 8,000 songs | 1,800 songs |
| 256 GB | 80,000 songs | 32,000 songs | 7,200 songs |
Lossy codecs (MP3, AAC, OGG) permanently discard audio data to achieve smaller files, typically 5-10x smaller than lossless. Lossless codecs (FLAC, ALAC, WAV) preserve all original data. FLAC is about 30-50% smaller than WAV while being bit-perfect.
CD quality (44.1 kHz/16-bit) captures frequencies up to 22 kHz, beyond human hearing range (~20 kHz). Higher sample rates (96 kHz, 192 kHz) offer theoretical benefits for production but provide no audible improvement for playback. The file size increase is substantial.
