Extract text from Multitrack audio files (MOGG)
To convert MOGG Audio files to another format, you need REAPER or other Audio software.
To convert other file formats to the "Multitrack Audio Container" file type, you need software like REAPER or a similar tool.
A .mogg file is a specialized multitrack audio container used predominantly by Harmonix Music Systems for the Rock Band series of rhythm video games. It packages multiple Ogg Vorbis audio streams into a single file. This allows the game engine to dynamically adjust the volume of individual instruments - such as isolating the guitar, bass, drums, or vocals - depending on the player's performance.
While designed for console games, PC users often extract these files to remix tracks or isolate vocal stems. The most reliable software to open and edit an unencrypted .mogg file is REAPER, a digital audio workstation that natively supports multitrack Ogg decoding. You can also read about the underlying format on the Wikipedia page for Ogg.
The main disadvantage of the .mogg format is its lack of universal compatibility. Standard media players like VLC, Windows Media Player, or Apple Music will fail to play it, or they might only play the first track. Furthermore, many newer Rock Band .mogg files are encrypted to protect copyrighted music, making them impossible to open without specialized, unofficial decryption tools. Because of this proprietary lock-in, users frequently need to convert the file to extract the audio stems.
The best conversion targets are individual OGG or WAV files for each audio stem. This preserves the isolated instruments. Converting to a single MP3 or FLAC will typically mix down all tracks into a single stereo file, destroying the multitrack advantage.
This file format is notoriously difficult to open or convert. Because it is often encrypted and uses a multi-stream layout, standard online converters fail to process it. Often, only specialized audio editors or the original game engine can properly read or export the data. However, just drag and drop your file onto convert.guru. We can identify the file format, inspect the file, and show text or internal headers. If our analysis detects an unencrypted underlying Ogg format, viewing or conversion may still be possible.
Convert.Guru analyzes your MOGG file, detects the exact format, and lets you read the text inside.
Users also converted OGG, WAV, FLP, GLS, RPP, RPP-BAK and MP3 files.
If you want to convert MOGG file to WAV, MP3, OGG, AAC, FLAC, WMA, M4A, AIFF, OPUS, ALAC, APE or WV, you can use REAPER or similar software from the "Multitrack game audio storage" 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 MOGG, try REAPER or another comparable tool in the "Multitrack game audio storage" 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 MOGG converter.
