Extract text from Adlib Tracker II instruments (A2I)
To convert A2I instruments to another format, you need Adlib Tracker II or other Audio software.
To convert other file formats to the "Tracker Instrument File" file type, you need software like Adlib Tracker II or a similar tool.
The .a2i file is an Adlib Tracker II Instrument file. It stores FM synthesis parameters, such as attack, decay, sustain, and waveform types, designed specifically for the OPL3 sound chip. Retro music producers and chiptune artists use these files to define unique synthesizer sounds in MS-DOS music trackers. You can open and edit these files using Adlib Tracker II.
The main disadvantage of the .a2i format is that it is not a standard audio file. It contains zero recorded audio data. Because it relies on mathematical synthesis instructions for a specific, obsolete hardware chip, modern audio players, web browsers, and standard DAWs cannot read or play it. To use these sounds in modern music production, you need to convert the instrument into sample-based target formats like WAV or FLAC.
This file format is difficult to open or convert directly. Standard online converters fail because they look for PCM audio streams and do not include OPL3 emulation to generate the sound. Often, only the original software can properly read or export the data. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your A2I file, detects the exact format, and lets you read the text inside.
If you want to convert A2I file to MP3, WAV, AAC, FLAC, OGG, WMA, M4A, AIFF, OPUS, ALAC, APE or WV, you can use Adlib Tracker II or similar software from the "FM Synthesis Instrument Data" category. In the File menu, look for Save As… or Export….
To convert MIDI, AAC, TTA, AU, WV, DTS, MID, FLAC, RA, MP3, PCM or WAV files to A2I, try Adlib Tracker II or another comparable tool in the "FM Synthesis Instrument Data" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our A2I converter.
