Expand description

Initialise a time scale context. This must be called before the first use of the context, to initialise its contents. \brief Initialise a time scale context. \param s The time scale context. \param sample_rate The sample rate of the signal. \param playout_rate The ratio between the output speed and the input speed. \return A pointer to the context, or NULL if there was a problem.
