## Introduction

Parlatype (that is libparlatype) is the core library for the Parlatype program, a basic audio player intended for speech transcription. The library is published separately as it might be useful for other applications as well.

PtPlayer is the core GStreamer backend that can be used as an audio player. PtWaveviewer is a GtkWidget to show a wave form and uses PtWaveloader to extract the wave form from a given file.

Parlatype is stable. That means that the library is versioned, API changes are documented, however, it changes frequently.

The library versioning is decoupled from release versions. The current release is 4.2, the API version is 5.0 (for GObject introspection) and the library’s soname is 7.0.2.
