This audio decoder module delivers accurate, high-quality playback and broad compatibility for embedded audio projects and retrofit installations. Key benefits High-resolution audio: 24-bit output provides detailed sound for clearer, more natural playback. Wide dynamic range and low noise: supports a 90 dB dynamic range and 85 dB signal-to-noise ratio, reducing background hiss and preserving quiet passages and transients. Flexible power requirements: DC 6 ~ 35 V ultra-wide operating voltage lets you run the module from common automotive, industrial, and portable power sources without extra converters. Broad sample-rate support: compatible with standard and legacy formats — 8 / 11.025 / 12 / 16 / 22.05 / 24 / 32 / 44.1 / 48 kHz — so it handles most audio files and sources without resampling artifacts. Native MP3 and WAV decoding: play compressed and uncompressed audio files directly, eliminating the need for an external decoder. Technical features Output resolution: 24-bit Dynamic range: up to 90 dB Signal-to-noise ratio: up to 85 dB Operating voltage: DC 6 ~ 35 V Supported sampling rates (kHz): 8, 11.025, 12, 16, 22.05, 24, 32, 44.1, 48 Supported formats: MP3, WAV Typical applications Automotive audio upgrades: integrate into car audio systems or head units where the 6–35 V tolerance fits both 12 V and 24 V vehicle systems. Embedded products and appliances: add reliable playback to kiosks, signage, industrial controllers, or consumer devices that require multiple sample-rate compatibility and robust audio quality. Portable and battery-powered systems: use the wide input-voltage range to simplify power design for portable speakers, hobby projects, or field equipment. Why choose this module Solves compatibility and power problems by supporting common file formats, a broad set of sample rates, and a flexible DC input range. Improves perceived sound quality in compact or resource-constrained systems with its 24-bit output and strong dynamic performance. Designed for straightforward integration into professional and hobbyist projects that need dependable audio decoding without extra hardware.
