Library for Acoustic Signal Processing
======================================
# Library for Acoustic Signal Processing
- 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)
Welcome to LASP: Library for Acoustic Signal Processing. LASP is a C++ library
@ -44,114 +46,42 @@ in a sister repository [lasp-doc](https://code.ascee.nl/ascee/lasp-doc).
If you have any question(s), please feel free to contact us: [email](info@ascee.nl).
# Installation - Linux (Debian-based)
# Installation - Linux (Ubuntu-based)
## Dependencies
## Prerequisites
- `$ 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`
Run the following on the command line to install all prerequisites on
Debian-based Linux, x86-64:
- `sudo apt install python3-pip libfftw3-3 libopenblas-base libusb-1.0-0 libpulse0`
## Installation from wheel (recommended for non-developers)
Go to: [LASP releases](https://code.ascee.nl/ASCEE/lasp/releases/latest/) and
download the latest `.whl`. Then run:
- `pip install lasp-*-linux_x86_64.whl`
## From source (Ubuntu-based)
### Prerequisites
Run the following one-liner:
- `sudo apt install -y git python3 python3-virtualenv python3-venv libopenblas-dev python3-pip libfftw3-dev libusb-1.0-0-dev libpulse-dev python3-build`
If building RtAudio with the ALSA backend, you will also require the following packages:
- `sudo apt install libclalsadrv-dev`
- libclalsadrv-dev
If building RtAudio with the Jack Audio Connection Kit (JACK) backend, you will also require the following packages:
- `sudo apt install libjack-jackd2-dev`
- libjack-jackd2-dev
### Download & build
## Download & build
- `$ git clone --recursive https://code.ascee.nl/ASCEE/lasp.git`
- `$ cd lasp`
- `pip install -e .`
# Building and installation for Raspberry Pi (Raspberry Pi OS)
For a release build:
Run the following on the command line to install all prerequisites on
Raspberry Pi OS:
- `$ cmake .`
- `sudo apt install libfftw3-dev libopenblas64-dev libhdf5-dev libclalsadrv-dev`
or optionally for a custom build:
In a virtualenv: install `build`
- `$ ccmake .`
- `$ pip install build`
Configure and run:
Then run:
- `$ make -j`
- `$ git clone --recursive https://code.ascee.nl/ASCEE/lasp.git`
- `$ cd lasp`
- `$ pyproject-build`
### Build documentation
Which will generate a `whl` in the `dist` folder, that is redistributable for Raspberry Pis that run Raspberry Pi OS.
When installing the `whl`, it appears that H5PY takes quite some time to install. To follow this process, run it it verbose mode.
# Installation - (x86_64) Windows (with WinPython), build with MSYS2
## Prerequisites
- Download and install [WinPython](https://winpython.github.io)
## From wheel
- Download latest wheel from [LASP releases](https://code.ascee.nl/ASCEE/lasp/releases/latest/) and
download the latest `.whl`. Then install with `pip`.
## From source
- Download and install [MSYS2](https://msys2.org). Make sure to install the
x86_64 version.
- When unzipping WinPython, make sure to choose a proper and simple path, i.e.
C:\winpython
- Download and install [Git for Windows](https://git-scm.com)
- Open an MSYS2 **MINGW64** terminal, and install some tools we require:
- `$ pacman -S git`
- Create a new virtualenv:
- `$ /c/winpython/<py-distr-dir>/python.exe -m venv venv`
- Add the venv-python to the path (eases a lot of commands)
- `$ export PATH=$PATH:~/venv/Scripts`
- Install `build`:
- `$ pip install build`
- Clone LASP:
- `$ git clone --recurse-submodules https://code.ascee.nl/ascee/lasp && cd lasp`
- If run for the first time, we have to install the libraries we depend on in
MSYS2 (this only has to be done on a fresh MSYS2 installation):
- `$ scripts/install_msys2_builddeps.sh`
- Copy over required DLL's to be included in distribution:
- `scripts/copy_windows_dlls.sh`
- And... build!
- `pyproject-build`
- Lastly: the generated wheel can be installed in the current virtualenv:
- `pip install dist/lasp*.whl`
# Documentation

`$ pip install doxypypy`

`$ <YOUR-BROWSER> doc/html/index.html`
# Usage
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.
# Development docs
## Bumping version number
When bumping the version number, please update the number in
- `pyproject.toml`
- `CMakeLists.txt`
Then, create a commit with tag `vX.X.X`, and push it.
## Updating to latest version (editable mode)
When updating to the latest version of LASP in editable mode:
```bash
- $ git pull
- $ git submodule update
- $ pip install -e . -v
