    Abstract: A headset system (1) comprising a first telecommunication device (3) comprising a desk phone or a computer (4) with an installed softphone, a second telecommunication device, such as a mobile phone or a smart phone (6), and a headset (2) comprising a cord (5) with a first connector (7), by means of which the headset (2) is adapted to be interchangeably connected to the first telecommunication device (3) and the second telecommunication device (6). The headset system (1) is adapted to transfer a call from the first telecommunication device (3) to the second telecommunication device (6), when the first connector (7) is unplugged from the first telecommunication device (3). The invention also relates to An external device (8) comprising a second connector (31) to be attached to a first connector (7) of a headset (2), means (9, 10) for connecting the external device (8) to a personal computer (4) with a softphone installed on it, a controller (36) adapted to send a call transfer control signal to the softphone, when the first connector (7) is unplugged from the second connector (31), whereby an active call on the first telecommunication device (4) is transferred to a second telecommunication device (6).

    Abstract: A method and a system of noise suppressing an audio signal comprising a combination of at least two audio system input signals each having a sound source signal portion and a background noise portion, the method and system comprising steps and means of: Extracting at least two different types of spatial sound field features from the input signals such as discriminative speech and/or background noise features, computing a first intermediate spatial noise suppression gain on the basis of the extracted spatial sound field features, computing a second intermediate stationary noise suppression gain, combining the two intermediate noise suppression gains to form a total noise suppression gain, wherein the two intermediate noise suppression gains are combined by comparing their values and dependent on their ratio or relative difference, determining the total noise suppression gain, applying the total noise suppression gain to the audio signal to generate a noise suppressed audio system output signal.

    Abstract: A method of and a system for synchronizing isochronous audio data frames provided by a USB interface to a clock of a wireless RF communication device is provided. The USB interface and the wireless RF communication device are connected via an I2S link, the method comprising receiving the isochronous audio data frames and the wireless RF communication device clock in a streaming controller, phase locking the isochronous audio data frames to a USB interface clock, counting start-of-frame pulses of the phase locked isochronous audio data frames, comparing the counted start-of-frame pulses with the wireless RF communication device clock to determine a difference signal, the difference signal triggering a synchronization event code when a threshold difference has been reached, rate matching the isochronous audio data frames to the wireless RF communication device clock upon receiving the synchronization event code.
