SPTK

This repository hosts a modified version of Speech Signal Processing Toolkit (SPTK) for embedded programs.

This version of SPTK is used by the following bindings:

• r9y9/SPTK.jl
• r9y9/pysptk
• r9y9/gossp

Note that if you want the command line programs of SPTK, please check the original one instead.

Supported Platforms

• Linux
• Mac OS X
• Windows

Changes

The important changes from the original SPTK are summerized as follows:

• Integrate waf build tool
• Add swipe inteface to SPTK.h SPTK.h#L382
• Windows 32/64 bit support. DLLs are avilable on the release page (https://github.com/r9y9/SPTK/releases)
• Avoid exit inside a function, as possible.
• Remove wavsplit and wavjoin from target sources to compile for cross-platform compilation ability, since original wavsplit and wavjoin use direct.h that only exists in POSIX enviroments. (#8)
• Add DLLEXPORT macro to expose API functions explicitly in MSVC environments (NOTE: this is not fully used for now) (#8)
• Ensure c89 compatibility
• Export excite function (#11)
• Cleanup and export RAPT function (#12)

Installation

Type the following commands from terminal:

./waf configure
./waf
sudo ./waf install
