    • A method and apparatus are provided for a first controlled device, such as a wireless local transmitter that accepts a plurality of digital audio signals and corresponding program information signals converted from a controlled source, such as the encoded digital data provided by a digital data signal source, typically a community antenna television (CATV) cable or direct broadcast satellite, then modulates said digital audio and corresponding program information signals on different carrier frequencies and transmits the modulated signals to a plurality of second controlled devices, such as remote digital receiver/tuners that demodulate said signals to output music in stereophonic sound and display the corresponding program information by means of an alphanumeric display. The first and second controlled devices contain microprocessor systems for communicating, controlling, storing, processing, and display of digital data within the operation of the respective system. A high speed, error free digital signal protocol is utilized for transmitting digital audio and corresponding program information signals to and from the digital receiver/tuner. The digital data transmitter and digital receiver/tuners utilize the 44.1 kilohertz (kHz) Compact Disc (CD) clock signal embedded in digital audio signals provided by an established delivery system to derive clocking signals for reception and processing of digital audio signals and for implementing the display information communications protocol.

    • Disclosed are systems and methods for wirelessly recording multi-track audio files without the data corruption or loss of data that typically occurs with wireless data transmission. In some aspects of the present invention, each performer is equipped with a local audio device capable of locally recording the respective performer's audio while also transmitting it to a master recorder. The locally recorded audio may then be used to repair or replace any audio lost or corrupted during transmission to the master recorder. Such repair or replacement may be performed electronically or via playback of the locally recorded audio. In other aspects of the present invention, a master recorder is not required since all locally recorded audio may be combined or otherwise processed post-recording. Locally recorded audio may include identifiers to aid in post-recording identification of such audio. A multi-memory unit is also provided to facilitate manipulation and processing of audio files.
    • 公开了用于无数据记录多轨音频文件的系统和方法,而没有数据损坏或通常在无线数据传输时出现的数据丢失。 在本发明的一些方面,每个执行者配备有本地音频设备,其能够本地记录相应的演奏者的音频,同时也将其发送到主记录器。 然后可以使用本地记录的音频来修复或替换在传送到主记录器期间丢失或损坏的任何音频。 这种修复或替换可以电子地或通过本地记录的音频的重放进行。 在本发明的其他方面,不需要主记录器,因为所有本地记录的音频可以被组合或以其他方式处理后记录。 本地记录的音频可以包括用于辅助记录这种音频的识别的标识符。 还提供了多存储器单元以便于音频文件的操纵和处理。
