Prior Art: Readers can explore prior art related to audio signal processing, volume adjustment, and dynamic range compression in audio technology patents and research papers.
Frequently Updated Research: Stay updated on the latest advancements in audio signal processing, dynamic range compression, and volume adjustment techniques for improved sound quality.
Questions about Audio Signal Processing: 1. How does dynamic range compression impact audio quality?
Dynamic range compression helps to reduce the difference between loud and soft sounds in audio, making it easier to hear all parts of the audio signal clearly.
2. What are the potential drawbacks of applying volume adjustments to audio signals?
Volume adjustments can sometimes lead to distortion or loss of audio quality if not applied properly.
Original Abstract Submitted
a method performed by an audio source device that is communicatively coupled with an audio output device, the method includes obtaining an audio signal; receiving a volume adjustment; applying the volume adjustment to the audio signal; applying dynamic range compression on the volume adjusted audio signal; and applying an inverse volume adjustment to the compressed audio signal, where the inverse volume adjusted audio signal is to be transmitted to the audio output device.
