Equalization: Adjusting the audio signal's frequency response to suit different playback environments or personal preferences.
Effects Processing: Adding effects such as reverb, delay, and echo to make the sound more expressive and rich.
Dynamic Range Control: Compressing the audio signal's dynamic range to reduce extreme volume changes and create a more balanced sound.
Filtering: Applying high-pass, low-pass, band-pass, or other filters to remove unwanted frequency components from the audio signal.
Stereo Imaging: Optimizing the audio signal's spatial positioning to enhance the sense of space in a stereo system.
Delay Compensation: Adjusting the timing of the audio signal to address phase issues between different speakers or audio devices.
By performing these functions, DSP helps the speaker deliver clearer and more expressive sound quality, adapting to various playback environments and user preferences.
