# Library for Acoustic Signal Processing
Welcome to LASP: Library for Acoustic Signal Processing. LASP is a C++ library
with a Python interface which is supposed to process (multi-) microphone
acoustic data in real time on a PC and output results.
- Master branch: [![Build Status](https://drone.ascee.nl/api/badges/ASCEE/lasp/status.svg?ref=refs/heads/master)](https://drone.ascee.nl/ASCEE/lasp)
- Develop branch: [![Build Status](https://drone.ascee.nl/api/badges/ASCEE/lasp/status.svg?ref=refs/heads/develop)](https://drone.ascee.nl/ASCEE/lasp)
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 :).
Welcome to LASP: Library for Acoustic Signal Processing. LASP is a C++ library
with a Python interface which is supposed to acquire and process (multi) sensor data in real time on a PC and output results.
Current features that are implemented:
- Compile-time determination of the floating-point accuracy (32/64 bit)
- Fast convolution FIR filter implementation
- Sample rate decimation by an integer factor of 4.
- Octave filterbank FIR filters designed to comply with IEC 61260
(1995).
- Communication with data acquisition (DAQ) devices, of which:
- Internal sound cards via the [RtAudio](http://www.music.mcgill.ca/~gary/rtaudio) backend. Many thanks to Gary P. Scavone et al.
- [Measurement Computing](https://www.mccdaq.com) [DT9838A](https://www.mccdaq.com/Products/Sound-Vibration-DAQ/DT9837) signal analyzer.
- Configuration of DAQ devices: AC coupling, IEPE, sensitivity physical
quantities.
- Recording of signals from these DAQ devices, and storing in a HDF5 file.
- Filter designers to create A/C sound pressure weighting
- Biquad filter designers for low pass, high pass, peaking and notch filters
- A Peak Programme Meter (PPM) to monitor signal levels from DAQ and to watch
for signal clipping.
- A signal generator to create sine waves, sweeps and noise (white / pink).
- Equalizers to equalize the output prior to sending.
- Averaged power spectra and power spectral density determination
using Welch' method. Taper functions of Hann, Hamming, Bartlett and
Blackman are provided.
- A thread-safe job queue including routines to create worker threads.
- Several linear algebra routines (wrappers around BLAS and LAPACK).
- A nice debug tracer implementation
- Third octave filter bank FIR filters designed to comply with IEC 61260
- (One third) octave filter bank filters designed to comply with IEC 61260
(1995).
- Slow and fast time updates of (A/C/Z) weighted sound pressure levels
- Full Sound Level Meter implementation
- Real time Sound Level meter, Power / Transfer function estimator
- Spectra data smoothing algorithms
- Sensor calibration for microphones
Future features (wish-list)
- Conventional and delay-and-sum beam-forming 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 (https://code.ascee.nl/ascee/lasp-doc).
- Conventional and delay-and-sum beam-forming algorithms
- Impedance tube measurement processing
For now, the source code is well-documented on [lasp.ascee.nl](https://lasp.ascee.nl) but it requires some
additional documentation (the math behind it). This is maintained

# Installation
# Building from source
## Dependencies
Two commands that install all requirements (for Ubuntu / Linux Mint)
- `pip install scipy numpy build scikit-build appdirs`
- `sudo apt install libusb-dev libpulse-dev libboost-dev`
## Runtime dependencies (Linux)
- FFTW (For really fast FFT's). If compiled with Ffftpack, this library is not
required.
- libUlDAQ, for the Measurement Computing DT9837A USB DAQ box
- GNU Autotools, for compiling libUlDAQ
- RtAudio, for Audio DAQ backends
- libusb
- BLAS (OpenBLAS, other).
## Editable install
In the root directory of the repository, run:
- `pip3 isntall --user -e .`
- `cmake .`
- `make -j`
- `$ sudo apt install python3-pybind11 libopenblas-dev python3-pip python3-scipy libusb-1.0-0-dev libpulse-dev cmake-curses-gui python3-h5py`
- `$ pip3 install --user -r requirements.txt`
## Build dependencies
Optional dependencies, which can be turned ON/OFF using CMake:
- Build tools: compiler [http://cmake.org](CMake), the Python packages:
- Scipy
- Numpy
- appdirs
These can all be installed using:
- The following Python packages need also be available:
- `Scipy` (which includes Numpy). Install with `sudo apt install
python3-scipy`, or `pacman -S scipy`.
- `appdirs`, which can be grabbed from [https://pypi.org](Pypi)
## Compilation of LASP
### Archlinux
Compiling the code on Archlinux requires the following packages to be available:
- openblas-lapack (AUR)
- Python>=3.7
- Numpy (Python-numpy)
- Cython
### Ubuntu / Linux Mint
*Only tested with Linux Mint 18.04*, we require the following packages for
compilation:
- build-essential
- cython
- python3-numpy
- libopenblas
If building RtAudio with the ALSA backend:
If building RtAudio with the ALSA backend, you will also require the following packages:
- libclalsadrv-dev
- libopenblas-base
- libopenblas-dev
- libusb-1.0-dev
If building RtAudio with the Jack Audio Connection Kit (JACK) backend, you will also require the following packages:
- libjack-jackd2-dev
## Download & build
- `$ git clone --recursive https://code.ascee.nl/ASCEE/lasp.git`
- `$ cd lasp`
For a release build:
- `$ cmake .`
or optionally for a custom build:
- `$ ccmake .`
Configure and run:
- `$ make -j`
### Build documentation
In directory:
`$ sudo apt install doxygen graphviz`
`$ pip install doxypypy`
While still in lasp dir:
`$ doxygen`
This will build the documentation. It can be read by:
`$ <YOUR-BROWSER> doc/html/index.html`
Or via docker:
`$ docker build -t lasp_ascee_nl:latest .`
## Install
For an editable install (while developing):
- `$ pip3 install --prefix=$HOME/.local -e .`
To install locally, for a fixed version:
- `$ pip3 install --prefix=$HOME/.local`
## Usage
- See examples directories for IPython notebooks.
- Please refer to the [documentation](https://lasp.ascee.nl/) for features.
