Abstract
An audio decoding and reading system comprises a computing module, a high-fidelity module, and a buffer-memory assembly which is between the computing module and the high-fidelity module. The buffer-memory assembly is intended to store a sliding segment of a digital audio stream which is transmitted by the computing module to the high-fidelity module. In this manner, a speed of processing of said digital audio stream by a digital-to-analog converter of the high-fidelity module, can be independent of a speed of production of said digital audio stream by the computing module. An improved sound emission quality results from this decoupling.
Claims12
An audio decoding and reading system, comprising:
- a computing module, suitable for:
- receiving audio files from an external source or reading audio files from a recording medium that is connected to said computing module, said audio files being encoded in accordance with a file format, called computer processing format, that is suitable for applying computer processing to said audio files and for performing operations on data contained in said audio files,
- generating at least one digital audio stream that is in accordance with a digital audio stream format, from at least one audio file received or read in the computer processing format, and
- receiving use commands entered by means of a user interface, which determine system settings or steps of an operating sequence of said system;
- and
- a high-fidelity module, which comprises a digital-to-analog converter and which is suitable for producing an analog sound emission signal from the digital audio stream, and said high-fidelity module being further adapted to execute some of the use commands,
- wherein the system further comprises:
- a buffer-memory assembly, which is arranged to store at least one segment of the digital audio stream produced by the computing module,
- a writing assembly, which is arranged to receive the digital audio stream produced by the computing module and to write said digital audio stream into the buffer-memory assembly, and
- a reading assembly, which is arranged to read the digital audio stream from the buffer-memory assembly, and to transmit the digital audio stream so read to the digital-to-analog converter,
- and the reading assembly is further adapted to allow a variable delay between a writing of data of the digital audio stream by the writing assembly into the buffer-memory assembly, and a subsequent reading of said data of the digital audio stream from said buffer-memory assembly, such that an instantaneous transfer rate of the reading is independent of an instantaneous transfer rate of the writing.
