-Library for Acoustic Signal Processing
+
+Welcome to LASP: Library for Acoustic Signal Processing. 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.
