The portable sound recorder (1) according to the invention comprises A) a plurality of microphones (1A-F) arranged for picking up voices or sounds from an external environment; B) a protective outer shell (10) that encloses: B.1) a logic unit (2) programmed or in any case arranged for processing the electrical or opto-electronic signals emitted by the plurality of microphones improving the quality of the sounds recorded; B.2) a mass memory (4) arranged for memorising and store/conserve the sounds picked up by the plurality of microphones; B.3) an electric power supply (6) that supplies the logic unit and the mass memory; and where the plurality of microphones comprises at least two microphones of the Micro-ElectroMechanical System (MEMS) type. The recorder is suitable for semi-professional use, is very small in size, can very faithfully reproduce atmosphere and directionality effects, is suitable for example for making cinematographic recordings or recordings of natural phenomena, live concerts or other music or sports events and press conferences.

In some embodiments, methods for generating an object based audio program including screen-elated metadata indicative of at least one warping degree parameter for at least one audio object, or generating a speaker channel-based program including by warping audio content of an object based audio program to a degree determined at least in part by at least one warping degree parameter, or methods for decoding or rendering any such audio program. Other aspects are systems configured to perform such audio signal generation, decoding, or rendering, and audio processing units (e.g., decoders or encoders) including a buffer memory which stores at least one segment of any such audio program.

Holographic sound is recorded and reproduced by way of a single monaural recording per left and right ear recorded. This is accomplished by determining the phase shift of frequencies recorded after dividing the sound into discrete frequencies in a recording device having resonators, each resonating at a different frequency, placed in a circular arrangement and divided into discrete channels by non-resonant material. The resonators are placed in a pseudo-randomized arrangement within the recording device and the circle of resonators is in front of a microphone which records the sound monaurally. Playback is then by way of arranging speakers or transducers into micro perforated sheets which amplify the sound, the arrangement of speakers/transducers around a central point. The sound is then played back directionally based on the position where the sound originally was recorded from and the position of the particular transducer around the central point.

Systems, methods, and sets for capturing and reproducing a binaural recording are provided. In one embodiment, an audio cable is disclosed for connecting a pair of binaural-recording earpieces of the present invention to one or more analog and/or digital audio devices, including but not limited to, cameras, videorecorders, smart phones, audio players and storage devices, and the like. The audio cable of the present disclosure provides for a binaural recording captured from earpieces of the present invention to be received by the one or more analog and/or digital audio devices as an audio input.

A method includes estimating a spatial coherence between a first diffuse sound portion in a first microphone signal and a second diffuse sound portion in a second microphone signal. The first microphone signal is captured by a first microphone and the second microphone signal is captured by a second microphone which is spaced apart from the first microphone in a known manner. The method further includes defining a linear constraint for filter coefficients of a diffuse sound filter, the linear constraint being based on the spatial coherence. The method also includes calculating at least one of signal statistics and noise statistics over the first microphone signal and the second microphone signal. The method also includes determining the filter coefficients of the diffuse sound filter by solving an optimization problem concerning at least one of the signal statistics and noise statistics while considering the linear constraint for the filter coefficients.

Systems, methods, and sets for capturing and reproducing a binaural recording are provided. In one embodiment, the binaural recording is captured using an earpiece set that includes a pair of earpieces each including a frame, a microphone, and a transducer. The frame is adapted to be worn on an ear, and defines an ear-insertion end and a posterior end opposite the ear-insertion end. The ear-insertion end is adapted to be positioned within an ear canal. The microphone is coupled to the frame for capturing ambient sound, and adapted to be positioned outside the ear canal and substantially coplanar with a tragus of the ear.
