Open Digital Sound Engine

FOSS cross-platform audio library and API for Windows and Linux, including legacy systems.

Current status: Public Alpha Testing, WIP

Main Features

• LPCM 8 and 16-bit samples playback
  supports local uncompressed RIFF/WAV files only yet

• Lightweight in use
  depending on the OS, OpenDSE consumes on average from 400 kB to 2 MB of RAM and up to 5% of the CPU load

• Multiple audio frontends
  supports WASAPIv2 and WaveOut for Windows and ALSA for Linux

• Backward compatibility
  Windows NT 3.1* or above, Linux 2.4 with ALSA 0.9.1** or above is required

• RMS value for each frame
  allows developers to create simple sound visualizations

_{* if the library is compiled in Microsoft Visual C++ 2.0
** tested in SUSE Linux 8.1}

Building

Windows

Minimal target: Windows NT 3.1 with Microsoft Visual C++ 2.0

To use OpenDSE in Microsoft Visual C++, run the BAT script in the VS Command Prompt profile:

cd [OpenDSE root]\build
make

...and then use OpenDSE.lib from out/bin in your projects to import OpenDSE.

Note

1. Windows NT 4.0 and below do not support interactive variable input. To build with debug symbols on these systems, specify the following arguments to the script:

make vc2 y

2. 16-bit Windows versions is not supported.

Linux

Mininal target: GCC 3.2 with glibc 2.0 and libasound2 0.9.1+

To use OpenDSE in GCC, you need to follow several steps:

1. Install the libasound2 development package from your distribution:

# Ubuntu / Debian
sudo apt-get install libasound2-dev
# openSUSE / SUSE Linux
sudo zypper install alsa-devel # or install from YaST2
# Arch/Artix Linux
sudo pacman -S alsa-lib
# Gentoo Linux
sudo emerge media-libs/alsa-lib

...or build it yourself;

2. Run the Shell script in your terminal:

cd [OpenDSE root]/build
chmod +x ./make.sh                        # if the *.sh script does not run
./make.sh --prefix /usr/local/lib

3. Use libopendse.a from out/bin in your projects to import OpenDSE.

Note

For extended support of legacy Linux distributions, a special flag --enable-legacy-support is provided, as well as --enable-debug for building the library with debug symbols.

Using OpenDSE in your own programs

Use the opendse.h C/C++ header file from include directory, after copying all the necessary header files to the root of your project.
