Embodiment Construction

[0016] will now refer to figure 1 To describe the first preferred embodiment according to the present invention, the figure is a high level block diagram of the audio recorder-player 1. Preferably, the audio recorder-player includes tuners 20 and 22 operatively coupled to antenna 10 . Preferably, each of the tuners 20 , 22 is controlled by a processor 30 which advantageously provides control signals to the tuners via an input / output (I / O) port 32 .

[0017] Processor 30 is operatively coupled to random access memory (RAM) 42 , nonvolatile random access memory (NVRAM) 44 and read only memory (ROM) 46 . RAM 42 provides temporary storage for data generated by programs and routines executed by processor 30, while NVRAM stores characterization results, ie data indicative of characteristics of the audio signal. ROM 46 stores programs and permanent data used by these programs. It should be mentioned at this point that the processor 30 may advantageously be one of a microprocessor ...

Abstract

An audio recorder-player (1, 100) comprising: M tuners (20, 22 or 120a-120n), which generate N audio signals sent by N audio sources; analyzers (30, 130) , which extracts RxN audio signal features from the N audio signals; memory (40, 140), which stores the RxN audio signal features; and an output circuit (60, 70 or 160, 70), which responds to Selection of at least one of said RxN audio signal characteristics reproduces an audio signal corresponding to one of said N audio signals, where R is a positive integer and M and N are positive integers greater than one. If desired, said audio recorder-player may advantageously be included in one of a radio, computer or set-top box. A method for operating the audio recorder-player is also described.

Description

technical field [0001] The present invention generally relates to audio entertainment systems. More specifically, the present invention relates to an audio entertainment system incorporating an audio recorder-player that allows recording of audio signals, processing and selective playback of recorded audio signals . Advantageously, the audio recorder-player allows a user to play live or recorded audio selections based on processing results for previously recorded audio signal samples. Background technique [0002] Software for performing speech recognition of live audio signals or audio signal files with acceptable accuracy, ie better than 95%, is commercially available. For example, U.S. Patent Nos. 4,277,644 and 6,101,467 cover various aspects of speech recognition software. Also, comparable methods for characterizing audio content are known. U.S. Patent Nos. 6,054,646 and 6,173,260 cover methods for characterizing music by tempo, energy, pitch, and the like. Addition...
