Guitar Pro users may receive a melody or performance as an M4A recording but need editable tablature in a GP4 project. These files hold different kinds of information: converting the recording requires note transcription, not just changing its file extension.
What the M4A format is
M4A is an audio container commonly used for AAC-compressed audio and, less often, Apple Lossless audio. Apple devices and apps, music players, and audio editors create or export M4A recordings. The file contains sound, not written notes or tablature.
What the GP4 format is
GP4 is the Guitar Pro 4 file format for guitar tablature and musical scores. A GP4 project can store notes, instrument tracks, timing, and score layout for editing and playback in compatible notation software. It does not store an M4A recording as editable musical notation.
How to convert M4A to GP4
A direct format conversion cannot turn recorded sound into accurate tablature automatically. The practical route is to transcribe the audio into MIDI, correct the notes and timing, then import the MIDI into a tablature editor and save as GP4.
Online on 101convert.com
101convert.com has a built-in converter. Upload the M4A file, choose GP4 as the output if it is offered, run the conversion, and download the result. Several files can be processed as a batch; the page shows a per-file size limit.
Because M4A contains audio and GP4 contains notation, ordinary file conversion does not perform transcription. Use this route only if the converter explicitly supports audio-to-notation transcription; otherwise, its output cannot be assumed to contain usable tablature.
Offline with desktop software
On Windows, macOS, or Linux, FFmpeg can decode M4A to WAV, Spotify’s open-source Basic Pitch can estimate notes and create MIDI, and TuxGuitar can import MIDI and save Guitar Pro 4 files. Install FFmpeg, Python, and Basic Pitch, then run:
ffmpeg -i input.m4a input.wavbasic-pitch output input.wav
In TuxGuitar, use File → Import → MIDI to open the MIDI produced in the output folder. Correct the instrument track, tuning, note positions, and rhythm, then use File → Save As and select the Guitar Pro 4 format.
Quality and compatibility
Audio-to-MIDI transcription estimates pitches and note onsets; it does not reliably identify guitar strings, fingering, bends, or complex overlapping parts. Review and edit the imported score before relying on it as tablature. Lossy AAC audio, distortion, and multiple instruments can make pitch detection less accurate.
