Extract text from Adlib Tracker II patterns (A2P)
To convert A2P patterns to another format, you need Adlib Tracker II or other Audio software.
To convert other file formats to the "FM Tracker Pattern File" file type, you need software like Adlib Tracker II or a similar tool.
An .A2P file is an Adlib Tracker II Pattern file, created by the classic MS-DOS audio sequencing software Adlib Tracker II. It contains precise musical pattern data - such as note pitches, timing, and effects - specifically designed to control the Yamaha OPL3 FM synthesis chip, which was popularized by early AdLib and Sound Blaster sound cards.
Because it is a relic of the MS-DOS era, opening an .A2P file today natively requires running Adlib Tracker II through an emulator like DOSBox. Alternatively, specialized chiptune and tracker media players, such as AdPlug or modern multi-format tracker plugins, can occasionally interpret the OPL3 instructions for playback.
Users typically need to convert .A2P files because they are practically unusable in modern environments. The core disadvantage of the format is that it does not contain actual audio waves - it is essentially a digital sheet music document that commands a vintage hardware synthesizer. Consequently, standard media players like VLC or Windows Media Player, as well as modern DAWs, cannot read or play the format.
The most realistic solution is to render the sequence into standard audio target formats like WAV, MP3, or FLAC. When rendering these files, it is crucial to remember that an .A2P only represents a 'pattern' (a single musical loop or segment), not a full song. Furthermore, because it relies on hardware FM synthesis, the rendered output may sound slightly different depending on the accuracy of the OPL3 software emulator used during conversion.
This file format is notoriously difficult to open or convert online. Most generic audio converters fail immediately because they look for waveform data and lack the complex OPL3 hardware emulation required to generate the sound. If our analysis detects compatible sequences, partial conversion or safe extraction may still be possible.
Convert.Guru analyzes your A2P file, detects the exact format, and lets you read the text inside.
Users also converted RTR and AST2 files.
If you want to convert A2P 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 "Tracker Audio Sequencing" 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 A2P, try Adlib Tracker II or another comparable tool in the "Tracker Audio Sequencing" 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 A2P converter.
