Yet Another Wavtool for UTAU

This is a drop-in replacement for the component wavtool.exe of UTAU song synthesizer.

• Input WAV audio in sample formats at up to 64-bit float

• Output WAV audio in sample format at 32-bits

• Support sample rates other than 44100 Hz

• Robust design allows it to try to work even with incorrect parameters

Install CMake, at least version 3.0.

Install MSYS2 on Windows or MinGW-w64 toolchain on Linux.

Switch to the directory of wavtool-yawu, type:

./configure -DCMAKE_TOOLCHAIN_FILE=tools/toolchain-i686-w64-mingw32.cmake -DCMAKE_EXE_LINKER_FLAGS=-static -DUSE_BUNDLED_SNDFILE=1
make

The resulting executable file is in build/wavtool-yawu.exe.

Open your project in UTAU, Select "Project" -> "Project Property" -> "Tool 1 (append)". Choose wavtool-yawu.exe.

It is not recommended to use wavtool-yawu with Cadencii or jCadencii. That is because Cadencii tries to read a temporary file generated by wavtool, but wavtool-yawu never produces any garbage temporary file.

You can try wavtool-pl instead.

If you really want to use with Cadencii, you have to configure and build wavtool-yawu with -DYAWU_OUTPUT_SAMPLE_FORMAT=SF_FORMAT_PCM_16.

After that, for Linux or OS X, open jCadencii, go to "Settings" -> "Preference" -> "Platform" -> "UTAU Cores" -> "wavtool" and select cadencii-yawu.

If you use UTAU with Wine on Linux, please check "Tools" -> "Option" -> "Rendering" -> "Note length calculated by GUI front-end". It is a known bug at UTAU side.
