Against common practice
| This scheme | Typical Bluetooth karaoke mic | Typical one-way 2.4 GHz mic | |
|---|---|---|---|
| Direction | One link. Stereo up and stereo down. | Voice goes over Bluetooth. The monitor often needs another connection. | Microphone to the receiver only. |
| Bandwidth | 48 kHz stereo, 256 kbps each direction. | Call mode is often 16 kHz narrowband. | Often mono, at a lower bitrate. |
| Time | Encode frame 2.5 ms. Air period 5 ms. | Bluetooth audio often reaches tens of milliseconds. | The uplink can be short. There is no monitor return. |
| Effects | Done on a separate chip. They do not take the encode window. | Effects and Bluetooth share one chip. | Effects are often added later, on the phone. |
| Interface | 24-bit stereo USB straight into the computer. | Depends on the phone's Bluetooth. | Often an analog jack, or mono USB. |
