Audio Recording Requirements
When it comes to audio recording, the requirements for data transfer rates are relatively modest compared to other applications, such as video editing or 3D modeling. However, the type of audio recording being done can impact the required data transfer rate.
For example, recording a single audio track at 44.1 kHz with 16-bit resolution requires a relatively low data transfer rate of around 1.4 Mbps. However, recording multiple tracks at higher resolutions, such as 96 kHz with 24-bit resolution, can increase the required data transfer rate significantly.
| Sample Rate | Bit Depth | Data Transfer Rate (Mbps) |
|---|---|---|
| 44.1 kHz | 16-bit | 1.4 |
| 96 kHz | 24-bit | 11.2 |
| 192 kHz | 32-bit | 22.4 |
As shown in the table above, the data transfer rate required for audio recording can vary significantly depending on the sample rate and bit depth. However, even at the highest resolutions, the required data transfer rate is still well within the capabilities of USB 2.0.
