In CCAligner, instead of passing a wave file, allow passing raw samples directly. In current implementation, the wave file is parsed and the raw samples are then stored in _samples. See here : https://github.com/saurabhshri/CCAligner/blob/master/src/lib_ccaligner/read_wav_file.cpp .

Introduce a new parameter -raw (see /src/lib_ccaligner/params.cpp) and store it directly in _samples in WaveFileData so that they can be used from there. Don't worry, this task is easier than it sounds.
