Audio Processing Tools Powered by Latest Research in Sound Perception
- Multi-band (24-band) high-resolution Dynamic Range Compression (DRC) detailed time-frequency sound analysis.
- Intelligent Loudness Control (ILC): Intelligent Loudness Control algorithm with enhanced subjective loudness models.
- Vocal Enhancement (VE): Vocal, and dialog enhancement.
- Bass Enhancement: Tunable bass boost module with 2-independent stages.
- High Frequency enhancement and Stereo Enhancement.
Features Optimized for FM Broadcasts
- Composite FM/MPX signal Generation with accurate 75 micro-sec or 50 micro-sec pre-emphasis and accurate peak limiting for maximizing modulate index of FM broadcasts.
- Digital Composite MPX available at 192 kHz.
- In box RDB/RBDS Encoder.
NielsenTM Watermarking Support In-Box Full Remote Control Through Networked PC Interface
Allow for remote control of the processor using SoundMaxTM Manager running on any PC present on the same Ethernet which automatically senses all available SoundMax hardware. Remote control features include:
- Tuning of profiles: basic/advanced tuning.
- Profile exports/import.
- Configuration of Internet streaming parameters.
Perceptual SoundMaxTM Advantage
- Enhanced Consistent Loudness: 24 Band Audio Processing allows packing in much higher audio density as compared to 5/6 band processing; thus significantly boosting the overall Sound consistency which results in much higher average modulation and enhanced coverage.
- Crisp & Clear Sound: State of art signal processing ensures that the processing output is free of any phase distortions and doesn't sound over-processed. Thus, it enhances clarity in addition to loudness and presence.
- Lively Broadcasts: Vocal Enhancement, Stereo Image Enhancement, Bass Enhancement, and available Sweetening tools make the sound livelier and pleasing to listen to.
- Embedded Deep Audio AI Technology: Incorporates novel optimized AI/ML based Audio classifiers and analysis. This Patent pending Real-Time Multi-Class Hierarchical Audio Classification Deep ML model accurately Classifies signal into Noise, Speech, Instrumental Music, Vocal Music, genres with high accuracy and high resolution. Useful in adaptively changing processing parameters for best quality.
