The AD1953 is a complete, 26-bit, single-chip, 3-channel digital audio playback system with built-in DSP functionality. Key features include: 3 channels of digital audio, 6-channel TDM output mode, a 7-band, 48-bit stereo equalizer, delays for loudspeaker location adjustment, Phat Stereo™ spatial enhancement, and a dual-band, professional-quality dynamics processor. Its three DACs achieve 112 dB signal-to-noise ratio (SNR) at 48 kHz. Its dynamic processing features include:
- Finely-tuned bass boost to enhance low frequencies for small loudspeakers
- Algorithms that virtually increase loudness by removing distortion at high volumes
- Midnight mode which automatically reduces loudness in high-volume instances (e.g., sudden loud scenes on DVDs)
- Low-level expansion to lift low-volume signals above road noise (for car stereos)
