Extract text from MPEG audio files (MPU)
To convert MPU audio files to another format, you need Winamp or other Audio software.
To convert other file formats to the "Compressed Audio File" file type, you need software like Winamp or a similar tool.
An .MPU file is simply an MPEG Layer 3 audio file, structurally identical to a standard MP3 file. These files store compressed audio data using lossy compression algorithms, maintaining near-CD audio quality (typically 16-bit, 44.1 kHz) while radically reducing the storage footprint. Historically, the .MPU extension was generated by obscure audio rippers, legacy naming errors, or older versions of media software like Nullsoft Winamp or Apple iTunes.
The fundamental disadvantage of the .MPU format is its total lack of recognition. Modern web browsers, mobile operating systems, and smart TVs rely heavily on standard file extensions to determine MIME types and trigger the correct audio decoder. Because .MPU is a non-standard and largely abandoned extension, native media players will refuse to open it - often throwing an "unsupported format" error despite the underlying data being a perfectly valid MP3. Sending an .MPU file to clients or colleagues practically guarantees playback failure unless the recipient possesses the technical know-how to force-open the file in a third-party application.
To ensure seamless playback across all devices, you must convert or re-wrap this file. For web streaming, mobile playback, and universal sharing, convert your .MPU to an MP3 or AAC. If you intend to edit the audio in digital audio workstations (DAWs) like Audacity or Adobe Premiere, convert it to an uncompressed WAV file to prevent further generation loss. For long-term lossless archiving, FLAC is the optimal target. Drag and drop your file below to analyze and convert it - free, online, and without installing software.

Users also converted M3U, MP3 and MP4 files.
If you want to convert MPU file to MP3, WAV, AAC, FLAC, OGG, WMA, M4A, AIFF, OPUS, ALAC, APE or WV, you can use Winamp or similar software from the "Audio File 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 MPU, try Winamp or another comparable tool in the "Audio File 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 MPU converter.
