Auto calibration of audio delay
The connected receiver or speaker may have different audio path latency due to different hardware, software, and DSP processing. To maintain the synchronization of each system, it's desirable to measure the audio path delay automatically. By leveraging the on-device microphone and proprietary algorithm, the entire audio path latency is measured automatically when it's connected to the receiver or speaker. The latency value will be used to maintain the perfect audio synchronization in wireless multi-room playback with HomePod, Echo, Google Home or other WiiM devices.
Super easy setup
WiiM Pro will pop up automatically in the WiiM Home app. Follow the in-app guide and start streaming music in less than 2 minutes.
Unrivaled Sound Quality up to 192 kHz/24-bit
Diverging from the norm of resampling to set sample rate and bit depth, WiiM Pro stands out by delivering unaltered audio up to 192kHz, 24-bit quality. That's the same as an artist's recording in the studio. The advanced TI PCM5121 DAC produces a remarkable 106 dB SNR and an impressive -92dB THD+N performance.
