Listento v3 offers 2 options. PCM 32-bit which is lossless and high fidelity but may require a larger network bandwidth, or use the the efficient OPUS format which also offers superb quality on lower bandwidth connections and allows singals over 0dB to be transmitted.
Other quality options allow for lossless PCM 24-bit and 16-bit audio signals, and lossy but efficient AAC quality which is a standard on many online platforms.
