Extract text from Casio FZ-1 voice dumps (FZF)
To convert FZF voice dumps to another format, you need Awave Studio or other Audio software.
To convert other file formats to the "Sampler Memory Dump" file type, you need software like Awave Studio or a similar tool.
The .FZF file is a proprietary memory backup, specifically a Casio FZ-1 Full Voice Dump. It was created in the late 1980s to store all the data held in a Casio FZ-series digital sampler's memory. These files bundle up to 8 sound banks, 64 instrument voices, and raw 16-bit PCM audio data into a single package. Originally, users extracted these files to a PC using an MS-DOS utility called FZDUMP, developed by Jeff McClintock, which transferred the data over a custom parallel-to-high-speed port cable.
Because .FZF is a highly specific hardware dump rather than a standard audio track, it is notoriously difficult to work with today. The format is closed, compressed using proprietary Casio specifications, and undocumented by modern standards. You cannot simply play an .FZF file in a media player or import it into a modern Digital Audio Workstation (DAW). The data combines raw audio samples with hardware-specific playback parameters - such as amplitude envelopes, key mapping, and loop points - that only the original synthesizer or specialized software can interpret.
Users typically need to convert .FZF files to extract the underlying audio or to modernize their vintage hardware setups. The best conversion targets for the raw audio are WAV files, though extracting just the audio means losing the Casio-specific envelope and loop settings. To preserve the instrument mapping, converting to SF2 (SoundFont) is recommended. Alternatively, if you want to load the sounds back into a physical FZ-1 equipped with a modern USB floppy emulator, you must convert the .FZF file into IMG or .HFE disk images.
Standard online audio converters fail to process .FZF files because they lack the reverse-engineered algorithms required to parse the Casio memory blocks. Dedicated digital music editors like Awave Studio are typically required to read or export the data properly.
Convert.Guru analyzes your FZF file, detects the exact format, and lets you read the text inside.
Users also converted G1R, G1N and FZB files.
If you want to convert FZF file to MP3, WAV, AAC, FLAC, OGG, WMA, M4A, AIFF, OPUS, ALAC, APE or WV, you can use Awave Studio or similar software from the "Sampler Memory Backup" 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 FZF, try Awave Studio or another comparable tool in the "Sampler Memory Backup" 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 FZF converter.
