Abstract: Embodiments of the invention relate to methods and systems for processing audio data, such as spatial audio data. One or more sound characteristics of a given component of a spatial audio signal are modified in dependence on a relationship between a direction characteristic of the given component and a defined range of direction characteristics. In some embodiments, a spatial audio in a format using a spherical harmonic representation of sound components is decoded by performing a transform on the spherical harmonic representation, in which the transform is based on a predefined speaker layout and a predefined rule, the predefined rule indicating a speaker gain of each speaker arranged according to the predefined layout, when reproducing sound incident form a given direction. In some embodiments, a plurality of matrix transforms is combined into a combined transform, and the combined transform is performed on an audio signal.

Abstract: A barrel conversion for a gun comprises; an external, peripheral surface suitably configured to fit and cycle the gun whose barrel (1?) is to be converted and a stepped internal bore. The stepped internal bore comprises a first, rifled portion (4?) of a first internal diameter extending from the chamber of the gun, and a second, clearance portion (3?) of a second internal diameter, the clearance portion (3?) extending from the rifled portion (4?) to the exit of the barrel (1?), and the second internal diameter being larger than the first internal diameter.
