ZX Spectrum Computer Sound Chip Emulator
- What is this
- This is Windows or Linux program, designed for playing music for AY-3-8912 sound chip (or its analogs are AY-3-8910 and YM2149F). Emulator emulates these sound chips and does not require real ones. Additionally emulator can play CD's audio tracks and MIDI-files. Optional BASS by Ian Luck can be used for playing MP3 and MOD music. Emulator can play files of next types:
1. Dumps of registers were recorded in many computers emulators:
2. Popular ZX Spectrum musical editors' modules:
- OUT (recorded in ZX Spectrum emulator 'Z80' v3.xx by G.A. Lunter);
- PSG (recorded in ZX Spectrum emulator 'Z80 Stealth' by Mr.Kirill, and in many other emulators);
- EPSG (recorded in ZX Spectrum emulator 'Z80 Stealth');
- YM ('StSound Project' by Leonard/Oxygen files, supported YM2, YM3, YM3b, YM5 and YM6 subtypes);
- VTX ('Vortex Project' by V_Soft files);
- ZXAY (designed specially for Ay_Emul).
3. ZX Spectrum's, Atari ST/STe's or Amstrad CPC's memory dumps with player for processor (Z80 or MC68000):
- ST1 - Sound Tracker v1.xx uncompiled;
- STC, ZXS - Sound Tracker v1.xx, Super Sonic v1.xx;
- PSC - Pro Sound Creator v1.xx;
- AS0, ASC - ASC Sound Master v0.xx-2.xx;

- AYM (RDOSPLAY project files);
- SNDH (Atari ST or Atari STe music files).
6. Files are played by BASS library:

- RMI - MID-files in RIFF-container;
- KAR - standard MID-files with song texts for karaoke;
- XMI - Miles Design XMIDI format.

For SNDH playing MFP, DMA-Sound and some TOS functions are emulated. For MC68000 emulation used Starscream 680x0 emulation library by Neill Corlett (firstname.lastname@example.org).
Emulator supports playlist files of Winamp (M3U, M3U8), XMPlay (PLS) and of own format (AYL), and also CUE-sheets for sound streams. AYL can contain full info about each item.
Emulator can be used as powerful tool for working with AY/YM data files. Built-in Speccy music ripper can to find modules of many ZX Spectrum musical editors in any source data. Emulator can convert modules to WAV, ZXAY, VTX, YM6 or PSG formats. Emulator can play digital sound is stored in OUT, ZXAY, EPSG, AY or AYM files. Beeper music in AY and AYM formats are supported too. Emulator can play all special effects are used by Atari ST musicians and stored in YM2, YM5 and YM6 formats.
Skin-files can change view of emulator main window.
BASS library is loaded only before playing corresponding file and unloaded immediately after stopping playing.
System requirements: for version before 2.9 - as minimum Windows 95, for version 2.9 beta 16 - minimum Windows 98 or Linux, since version 2.9 beta 17 Windows 9x is not supported; for work processor 386 or greater is required; for playing sound card with support of 8 or 16 bit Stereo or Mono digital sound at any sample frequency in range from 8000 to 300000 Hz and high performance processor (Pentium 133 is tested). Some beeper music in AY and AYM files require Pentium 166 MHz and higher. By default emulator uses special filter which requires more powerful processor, but it gives more quality sound chip and beeper emulation. For playing extra file types of BASS require DirectX 3 or above (in Windows), for MOD music additionally processor with MMX is required.
- Emulator distribution
- AY Emulator is distributed in two kinds at one time: as archives with compiled Ay_Emul (for Windows and Linux) and as file archive with AY Emulator source code. Last you can download from to the Programmer part.
- Emulator skins
- Emulator author and its designer have no wish to make additional skins for Emulator. So, only you, dear Emulator user, can to grow skin collection on this page. I had made all for easing this process. You can download program 'Skin Manager II'. Program contains skin example (use it as template) and needed instructions. Please, send all skins which you'll make to the Emulator author for publication on this site.
- Plug-ins, Linux-versions and other
- All emulator source codes are available, so, averybody can make plug-in for favorite player or port for other operational systems or platform. At the moment, Martin Andersson has made Ay_Emul port for Linux and plug-in for XMMS player. Download SquareTone with sources from to the Programmer part. Since v2.9 beta 6 Ay_Emul can be compiled for Linux.
- Download archives
- The most actual version of Ay_Emul is version 2.9 beta 26. Experimental Ay_Emul 3.0 alpha (only WinAPI using) is on initial state. Source of these and other emulator versions can be downloaded from to the Programmer section.
