  This is the AY/YM sound chip emulator. These chips was used in such
computers as Sinclair ZX Spectrum 128Kb(AY8912), Atari and some others.

  This library allow to use AY/YM sound effects and music in your own
programms, games, demos, etc. User must pass to library array of AY/YM
registers (14-bytes) and library will generate sound stream by this.

format documentation and samples of use the library API.

  VTX format is made for store AY/YM song in lha5 complession. This
library can read sond info header and unpack lha5 compressed data from
vtx file. There are thousands songs from games, magazins, demos
