Detailed Description

Connects WSOLA to the audio system using JackClient.

Constructor & Destructor Documentation

◆ WSOLAJack()

WSOLAJack::WSOLAJack ( string fileName )

inline

Constructor Using the filename, open the audio file, read the first block of data, connect to and configure Jack. Also process the first block to init any memory in the first pass of WSOLA.

Parameters

fileName The name of the audio file to open.

Member Function Documentation

◆ processAudio()

int WSOLAJack::processAudio ( jack_nframes_t nframes )

inlineprivatevirtual

The Jack client callback. Initialises by setting up the output buffers. Steps through all nframes in chunks of N/2 output samples. Outputs the last N/2 chunk of samples, processes a new chunk, Reads in a chunk. Exits. Returns non-zero when new samples can't be retrieved from file.

Implements JackClient.
