Free online AY to MP3 converter

AY files are chiptune data, not recordings, so a player or editor that accepts ordinary audio files cannot always open them directly. Converting one to MP3 renders its synthesized music into a format that phones, media players, and audio editors commonly support.

What the AY format is

An AY file stores music data for emulating programmable sound generator chips such as the AY-3-8910 and Yamaha YM2149. AY music is associated with systems including the ZX Spectrum and Amstrad CPC; files often contain several tunes from a game or other program. AY players and emulators interpret the data and generate the sound during playback, rather than reading recorded audio samples.

What the MP3 format is

MP3 is a widely supported, lossy audio format. It is useful for sharing, portable playback, and importing into software that does not read chiptune formats. Because MP3 stores rendered audio, it does not preserve the AY data or allow you to change the original chip instructions.

How to convert AY to MP3

Online on 101convert.com

1. Upload the AY file on the converter page. You can add several files for batch conversion; each file is subject to the size limit shown on the page.
2. Before converting, set the bitrate, sample rate, and channel count if needed.
3. Start the conversion, then download the MP3 file.

The page’s converter uses FFmpeg on its server.

Offline with desktop software

On Windows, foobar2000 can decode AY files using the foo_input_gme Game Music Emu component. Install foobar2000 and the component, then configure an MP3 encoder such as LAME if one is not already available. Add the AY file to a playlist, select the tune you want, and use 右-click → Convert → … to choose MP3 output and start conversion. Menu wording can vary by foobar2000 version.

AY files may contain multiple tunes, so select the intended track before converting. Check the rendered duration: chiptune tracks can loop, and the conversion’s playback-length setting determines how much of a tune is written to the MP3.

Quality and limitations

The conversion emulates the sound chip and encodes the result; it is not a lossless copy. Use a higher MP3 bitrate when retaining more audio detail matters, but converting back to AY cannot recover the original music data. Channel settings can affect the rendered sound because some players apply stereo panning even though the original sound chips generate channels separately.
