Abstract: A microphone having a multi-channel mixer and one or more connectors usable to receive and/or output audio. Any of the connectors may be used as an input connector, as an output connector, or configured to be switchable between being an input and an output connector. The user of the microphone may be able to conveniently use one or more of the connectors to expand the microphone to become part of a larger setup that uses multiple microphones. For example, an XLR connector of the microphone may be passive, and may be configured such that a user can daisy chain the output from an XLR connector of another microphone into an XLR connector of the microphone. In such an arrangement, an output based on one or both of the microphones may be output through another connector of the microphone, such as a USB connector.

Abstract: A filter that may increase and extend, the bass frequency response of a speaker of an audio device. The filter may be space-efficient. The filter may be part of a device that does not necessarily have a large rear cavity and that does not necessarily have porting and/or passive radiating. The low-frequency extension filter may be used, for example, with a smaller rear cavity while essentially simulating the acoustic effects of a much larger rear cavity. The low-frequency extension filter may include a plurality of acoustic pathways, such as tubes, which may wind around along a tortuous path and which may resemble a labyrinthine design. The tubes may be selected to resonate with particular predetermined low frequency channels. For example, the tubes may be approximately a quarter wavelength of the center of the corresponding frequency channel, or even slightly shorter.

Abstract: An audio device may be configured to have multiple modes of operation. The mode of the device may be associated with a particular geometric configuration of the device, such as by swiveling an arm of the device and/or changing the orientation of the device with respect to gravity and/or a surface (e.g., table) on which the device rests. The device may determine the appropriate state based on the current geometry, and based on the state may tune the device for a particular operation suited for that geometry. For example, different signal processing parameters may be applied, different microphones may be enabled and disabled, and/or different acoustic conditions may be provided (for example, different modes of a passive radiator) based on the mode.

Abstract: Array microphone systems and methods having adjustable lobe shapes are provided. The lobe shapes of pickup patterns in an array microphone may be adjusted by weighting the audio signals of subsets of the microphone elements that make up the array. The lobe shapes may be adjusted in a direction independent of a steering vector of the lobe. Users may have greater control of lobes which can result in more efficient and optimal coverage of audio sources in environments.

Abstract: Offset cartridge microphones are provided that include multiple unidirectional microphone cartridges mounted in an offset geometry. Various desired polar patterns and/or desired steering angles can be formed by processing the audio signals from the multiple cartridges, including a toroidal polar pattern. The offset geometry of the cartridges may include mounting the cartridges so that they are immediately adjacent to one another and so that their center axes are offset from one another. The microphones may have a more consistent on-axis frequency response and may more uniformly form desired polar patterns and/or desired steering angles by reducing the interference and reflections within and between the cartridges.

Abstract: Disclosed is methods of preparing a cannabinoid extract or cannabinoids from Cannabis biomass. The biomass can be at any degree of hydration, from damp with external water, to dried. The methods use a triacylglyceride (TAG) oil to extract cannabinoids into the TAG oil at +5° C. to +45° C. The enriched oil is then optionally further processed. If the TAG was either triacetin or tributyrin, the further processing can be done directly using reverse phase chromatography.
