Audio

Sound output and sample rates. NX Redux negotiates the sample rate with whatever output is active: 48 kHz on the speaker, the negotiated Bluetooth rate, or a USB DAC's supported rates.

• It uses high-quality in-app resampling instead of silent low-quality system resampling.
• Hot-plugging a USB-C DAC or connecting Bluetooth mid-playback reroutes audio automatically.
• A headphone icon appears in the status bar while an external output is active.

Output

The current audio sink and its sample rate, live. For example Speaker – 48000 Hz, or your DAC/Bluetooth device when connected.

Volume

Master volume.

Rate negotiation

Auto negotiates the best rate with the active output; forcing 48 kHz is the escape hatch if a device misbehaves.

Bluetooth max sampling rate

Caps the sample rate used for Bluetooth audio.
