Description
R2S15904SP is an optimum audio signal processor IC for TV. The IC has a 5ch input selector, surround/pseudo stereo, tone control(2band), output gain control and 2ch master volume. The IC can control all of these functions with I2C bus. An audio signal processor IC, also known as an audio DSP (Digital Signal Processor), is an integrated circuit designed to process and manipulate audio signals. It is commonly used in audio equipment and systems to enhance audio quality, apply various audio effects, and perform audio signal processing tasks.
1. Audio signal processor ICs often include a range of built-in audio effects such as equalization (EQ), filtering, delay, reverb, compression, and modulation effects. These effects can be used to shape and enhance the audio signal.
2. Many audio signal processors allow for multiple audio signals to be mixed together, enabling the blending of different audio sources or channels.
3. Audio signal processor ICs may include analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) to convert audio signals between analog and digital formats.
