Bit Rate vs Sample Rate
Formule
## Digital Bit Rate ### Formula **Bit Rate = Sample Rate x Bit Depth x Channels** For example, CD audio is 44.1 kHz x 16 bits x 2 channels = 1411.2 kbps. This is the uncompressed data rate before any codec.
Exemple Résolu
CD audio: 44.1 kHz, 16-bit, stereo.
- 01Bit rate = 44.1 x 16 x 2 = 1411.2 kbps
- 02Bit rate = 1.411 Mbps
- 03Bytes/sec = 44100 x 16 x 2 / 8 = 176,400 B/s
Questions Fréquentes
What is the difference between bit rate and baud rate?
Bit rate is bits per second. Baud rate is symbols per second. With multi-bit symbols, bit rate = baud rate x bits per symbol.
How does compression affect bit rate?
Lossless (FLAC) compresses to ~50-60% of raw. Lossy (MP3) compresses to 10-25% with some quality loss.
What bit rate do I need for USB?
USB 2.0 supports 480 Mbps, USB 3.0 supports 5 Gbps. Check that your data rate fits within the interface bandwidth.
