==RESAMPLING OUTPUT SIGNALS OF QMF BASED AUDIO CODECS - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240046942 titled 'RESAMPLING OUTPUT SIGNALS OF QMF BASED AUDIO CODECS

==Simplified Explanation==

The patent application describes an apparatus for processing an audio signal. The apparatus includes a configurable first audio signal processor that can process the audio signal based on different configuration settings to obtain a processed audio signal. The apparatus is designed in such a way that different configuration settings result in different sampling rates of the processed audio signal. Additionally, the apparatus includes an analysis filter bank with a certain number of analysis filter bank channels, a synthesis filter bank with a different number of synthesis filter bank channels, a second audio processor for receiving and processing an audio signal with a predetermined sampling rate, and a controller for controlling the number of analysis filter bank channels or synthesis filter bank channels based on the configuration setting.

* The apparatus can process audio signals with different configuration settings, resulting in different sampling rates of the processed audio signal.
* It includes a configurable first audio signal processor that can be adjusted to different settings for processing the audio signal.
* The apparatus has an analysis filter bank with a certain number of channels and a synthesis filter bank with a different number of channels.
* A second audio processor is included to receive and process an audio signal with a predetermined sampling rate.
* The controller is responsible for controlling the number of analysis filter bank channels or synthesis filter bank channels based on the configuration setting.

Potential applications of this technology:

* Audio signal processing in various devices such as smartphones, tablets, and audio systems.
* Music production and recording studios.
* Communication systems for voice processing and enhancement.
* Audio streaming and broadcasting platforms.

Problems solved by this technology:

* The apparatus allows for flexible processing of audio signals by providing different configuration settings.
* It enables the processing of audio signals with different sampling rates.
* The analysis and synthesis filter banks provide efficient and accurate audio signal processing.

Benefits of this technology:

* Improved audio signal processing capabilities.
* Enhanced flexibility in adjusting the configuration settings for different audio processing requirements.
* Efficient utilization of analysis and synthesis filter banks.
* Improved audio quality and fidelity in various applications.
