Soundpipe is a lightweight music DSP library written in C. It aims to provide a set of high-quality DSP modules for composers, sound designers, and creative coders.
sudo make install
Tests in Soundpipe are used to determine whether or not modules behave as expected. Tests write the output of a module to memory, and check the MD5 hash value of the output against the MD5 value of a reference signal.
To build a test file, go into the test folder, and run "make". Then, run "./run.bin", which runs the tests. As the tests are run, an "ok" will appear in the log if a test passes, and a "not ok" will appear if a test fails.
It is possible to hear the output of a particular test if you know the test number. You will need to have sox installed. For example, to hear what test 11 sounds like, run the following commands:
./run.bin render 11
This will generate a file called out.wav.
The testing utility has a few optional arguments. To see all possible arguments, run "./run.bin help".
Soundpipe is callback driven. Every time Soundpipe needs a frame, it will call upon a single function specified by the user. Soundpipe modules are designed to process a signal one sample at a time. Every module follows the same life cycle:
If you have lua installed on your computer, you can generate the current html documentation for soundpipe by running "make docs". A folder called "docs" will be created. The top page for the documentation is docs/index.html.
