Free online ABC to WAV converter

Music notation software stores ABC as text, while audio editors, samplers, and playback devices often require rendered PCM audio. Converting it to WAV creates a synthesized performance that can be edited, mixed, shared, or archived.

What the ABC format is

ABC is a plain-text music-notation format used for folk tunes, traditional music, melodies, lead sheets, and simple polyphonic scores. An .abc file contains fields such as title, meter, key, tempo, and composer, followed by symbols for notes, durations, rests, decorations, chords, voices, and lyrics.

Folk-music collectors, composers, notation users, and developers exchange ABC because it is compact, editable, and readable without specialized software. Applications such as EasyABC, ABC Explorer, and the abcMIDI tools can read or generate it. ABC stores musical instructions rather than recorded sound, so a synthesizer must interpret those instructions before WAV audio can be created.

What the WAV format is

WAV is an audio container commonly used for uncompressed PCM recordings. Music editors, digital audio workstations, samplers, media players, and hardware devices widely support it.

PCM WAV avoids the lossy compression used by MP3 and is therefore suitable for editing, mixing, sound-library production, and archival masters. The files are larger than compressed audio. Typical rendering settings are 44.1 kHz or 48 kHz sample rate, 16-bit or 24-bit depth, and mono or stereo channels; use the settings required by the destination software or device.

Convert ABC to WAV online

1. Open the ABC-to-WAV converter on 101convert.com.
2. Upload the .abc file and select WAV as the output format.
3. Start the conversion and download the generated .wav file when processing finishes.

The converter renders notation with its available synthesizer and instrument settings. The result is not an original recording, and the available controls may not match those of desktop notation software.

Convert on a computer with abcMIDI and TiMidity++

1. Install the abcMIDI package, which provides abc2midi, and install TiMidity++ with a General MIDI soundfont.
2. Convert the notation to MIDI with abc2midi song.abc -o song.mid.
3. Render the MIDI file as a WAV file with timidity song.mid -Ow -o song.wav. The -Ow option selects RIFF WAV output in common TiMidity++ builds.
4. Open song.wav in an audio editor and check the tempo, repeats, instruments, voices, and ending.

TiMidity++ uses its configured soundfont and instrument mapping, so changing the soundfont changes the timbre without changing the ABC notation. Use timidity --help to check the options supported by the installed build, including output rate and channel settings.

Use graphical notation software

Open the file in an ABC-compatible program such as EasyABC, then verify the key, meter, tempo, repeats, voices, and instruments. If the program offers audio rendering, use its WAV export command, such as File → Export → WAV. If it exports only MIDI, save the MIDI file and render it with TiMidity++ or another MIDI synthesizer.

Quality and compatibility limits

The output is a new synthesized performance. ABC does not contain microphone audio, the original performer’s timing, room sound, or fixed instrument recordings. The result depends on the synthesizer, soundfont, MIDI interpretation, tempo settings, and supported ABC dialect.

Inspect unsupported or altered decorations, tuplets, grace notes, lyrics, repeats, transposition, and multiple voices. ABC files containing several tunes may produce separate MIDI sections or one continuous rendering, depending on the application. Different ABC readers can also interpret optional syntax differently.

Render directly to PCM WAV when further editing is required. Converting a previously rendered 16-bit file to 24-bit does not restore detail; it only changes the storage format. Preserve the original .abc file alongside the WAV because the WAV cannot be converted back into the original notation and performance instructions exactly.
