WAV recordings need to become GP4 when a music-composition workflow requires a Guitar Pro 4 score or tablature rather than playable audio. The conversion therefore has to identify notes in the recording; it cannot preserve the WAV waveform inside a GP4 file.
What the WAV format is
WAV is a container commonly used for uncompressed PCM audio. Audio recorders, DAWs such as Audacity and Reaper, and operating-system recording tools often create WAV files for editing or exchanging recordings without lossy compression.
What the GP4 format is
GP4 is the Guitar Pro 4 file format for music scores and tablature. It stores musical events and score information—such as notes, tracks, and timing—not recorded sound. Use it to edit or share a Guitar Pro arrangement; it cannot reproduce the original recording’s voice, instrument tone, or room sound.
How to convert WAV to GP4
Audio-to-score conversion is transcription, not a direct format-preserving conversion. The software must estimate pitches and timing from the recording, and the result may need correction.

Offline with desktop software
For a local workflow, Spotify’s open-source Basic Pitch can transcribe audio to MIDI, and Guitar Pro 4 can import MIDI and save the score as GP4. Install Basic Pitch in a Python environment, then run:
basic-pitch output-directory recording.wav
In Guitar Pro 4 for Windows or macOS, open the generated MIDI using File → Import → MIDI, review the imported tracks and notation, then save with File → Save as using the GP4 format.
Quality and limitations
Basic Pitch’s MIDI transcription is an estimate: overlapping instruments, percussion, distortion, and reverberation can make pitches or note boundaries unclear. MIDI also does not retain the WAV’s audio quality or instrument sound. Review the imported score and correct errors before relying on the GP4 file.
