LASP is a C +library - currently still under heavy development - with a Python +interface which is supposed to process (multi-) microphone acoustic +data in real time and output results. + +The main goal of this library will be the processing of data from an +array of microphones real time, on a Raspberry PI. At the point in +time of this writing, we are yet unsure whether the Raspberry PI will +have enough computational power to this end, but may be by the time it +is finished, we have a new faster generation :). + +Current features that are implemented: +- Compile-time determination of the floating-point accuracy (32/64 bit) +- Fast convolution FIR filter implementation +- Decimation of the sample rate by an integer factor of 4. +- Octave filterbank FIR filters designed to be compliant to IEC 61260 + (1995). + + +Some of the near future features: +- Third octave filter bank +- Slow and fast time updates of (A/C/Z) weighted sound pressure levels +- Conventional and delay-and-sum beamforming algorithms + +For now, the source code is well-documented but it requires some +additional documentation (the math behind it). This will be published +in a sister repository in a later stage. + +If you have any question, please feel free to contact us: info@ascee.nl. +
