Introduction

Joel W. Page, an accomplished inventor based in Austin, TX, has made significant advancements in the field of audio data processing with a total of 13 patents to his name. His innovations focus on enhancing the speed and flexibility of sample rate conversion, which has broad applications in audio technology and streaming.

Latest Patents

Among his latest patents, Page has developed systems and methods for implementing a sample rate converter using a combination of hardware and software. This invention is designed to maximize both speed and flexibility when converting a digital input data stream from a first sample rate to a second, fixed sample rate. In one embodiment of the system, a rate estimator estimates the sample rate of an input data stream. A phase selection unit selects a phase for interpolation of a set of polyphase filter coefficients based on the estimated sample rate. The coefficient interpolator then interpolates the filter coefficients based on the selected phase, and a convolution unit convolves the interpolated filter coefficients with samples of the input data stream to generate a re-sampled output data stream. This system allows shared hardware or software components between multiple channels, facilitating the processing of data streams with independently variable sample rates.

Another notable invention by Page focuses on streaming multi-channel audio as packetized data or parallel data with a separate input frame sync. This system converts a data stream from a first sample rate to a second sample rate, particularly when data is received in bursts. One embodiment includes receiving bursty audio data on a first input line while synchronization data is received on a second input line. By estimating the input sample rate based on synchronization data and the audio data, the technology efficiently converts the audio data to an output sample rate.
