    • Controlling a multimedia software application using high-level metadata features and symbolic object labels derived from an audio source, wherein a first-pass of low-level signal analysis is performed, followed by a stage of statistical and perceptual processing, followed by a symbolic machine-learning or data-mining processing component is disclosed. This multi-stage analysis system delivers high-level metadata features, sound object identifiers, stream labels or other symbolic metadata to the application scripts or programs, which use the data to configure processing chains, or map it to other media. Embodiments of the invention can be incorporated into multimedia content players, musical instruments, recording studio equipment, installed and live sound equipment, broadcast equipment, metadata-generation applications, software-as-a-service applications, search engines, and mobile devices.

    • A system 100 for wireless communication is provided. The system 100 includes first communication device 110A operable to transmit a message 300 according to a new protocol. The new protocol having a header 302 including a first rate field and a first length field, a header extension 304 including a second rate field and a second length field, and a data 306. When the message 300 is received by a legacy communication device 102 which is operable to receive a portion of the message 300 according to a legacy protocol, the legacy communication device 102 refrains from transmitting for a duration indicated by the combination of the first rate field and the first length field. The system 100 also includes a second communication device 110B operable to receive the message 300 according to the new protocol. A method of communicating to maintain compatibility with legacy devices is also provided.

    • A method and assembly for frequency stabilization of an optical signal especially from a laser, the assembly (11) comprising beam splitter (15), a passive frequency discriminator (16), and a pair of photodiodes (17 & 18). The beam splitter (15) in use receives a collimated optical beam (B) and diverts a sample beam (B1) which is directed towards the discriminator (16) which transmits a portion (B2) of said sample beam to one of the photodiodes (17) and reflects a second portion (B3) of said sample beam to the other photodiode (18). A control signal (S3) is derived from the respective intensities of the transmitted and reflected portions of the sample beam, and utilized to operate the electronic control to adjust the frequency of the laser output signal, if required, to maintain a specified frequency.
