    Abstract: A method and apparatus for extracting and changing the reverberant content of an input signal is provided. The method of estimating an impulse response for a reverberant system includes sampling a signal from a reverberant system, having an impulse response, into a sequence of blocks, for each block of the sequence, determining a magnitude in dependence upon a magnitude of a previous block, forming an estimate of the impulse response using determined magnitudes as parameters for a finite impulse response filter. The method of creating a multi¬ channel signal using a signal with fewer channels from a reverberant system includes sampling the signal from a reverberant system, having an impulse response, into a sequence of blocks, for each block of the sequence, determining a magnitude in dependence upon a magnitude of a previous block, forming an estimate of the impulse response using determined magnitudes as parameters for a finite impulse response filter, applying an inverse of the estimated impulse response to the signal to derive at least one of a direct signal component and a reverberant signal component, and recombining the direct signal component and the reverberant signal component to create a multi-channel signal.

    Abstract: The invention makes use of impulse responses of the performance venue to process a recording or other signal so as to emulate that recording having being recorded in the performance venue. In particular, by measuring or calculating the impulse responses of a performance venue such as an auditorium between an instrument location within the venue and one or more soundfield sampling locations, it then becomes possible to process a "dry" signal, being a signal which has little or no reverberation or other artifacts introduced by the location in which it is captured (such as, for example, a close microphone studio recording) with the impulse response or responses so as to then make the signal seem as if it was produced at the instrument location in the performance venue, and captured at the soundfield sampling location.

    Abstract: A laminated artificial pinna having a concha, fossa and auditory canal. The auditory canal (23) is constructed and arranged relative to the concha (12), so that the distance (A) (see figure 7) from the centre of the entrance of the auditory canal (23) to the rear wall of the concha (12) lies within the range of 15 mm to 20 mm, the distance (B) (see figure 8) from the centre of the entrance of the auditory canal to the concha floor lies within the range of 9 mm to 15 mm, and the alignment of the turning point (C) (see figure 9) with the centre of the entrance of the auditory canal (23) is substantially horizontal. The pinna is made with the help of an encapsulated model of a human pinna. A cross-sectional shape is revealed by incrementally machining the encapsulated model away and of each revealed cross-sectional shape an image is taken. The image is used to produce a replica of the cross section out of sheets of material which are assembled in a stack to form the laminated model of the pinna.

    Abstract: A process and device (24) for triggering a measurement process for evaluating the quality of audio and/or speech signals enable field measurements to be carried out to determine the quality of a digital transmission. During a first step, digital values of a reference signal underlying at least part of a test signal whose quality is to be evaluated are stored. Digital values of the test signals are also at least temporarily stored. The degree to which a section of the reference signal values coincides with the test signal values is determined to trigger the measurement process as soon as a predetermined degree of coincidence is exceeded, in order to compare a further section of the reference signal values to the test signal values in the relative position in time of the reference signal and test signal values at the moment when a predetermined degree of coincidence occurs.
