Nintendo Ultra64 Sound Format (USF) is a format of file developed by Adam Gashlin to store sound data (just like PSF for the PlayStation) extracted directly from a video game Nintendo 64.

Files USF are manually generated ROMANIAN video games by isolating the codes responsible for the reading from the music, plus the musical data. The remainder of the Octet S of the ROMANIAN are put at zero and the resulting data are stored in a dense table (the null bytes are not stored in the USF, therefore the not specified bytes are regarded as null) but without compression. The file also contains a state of safeguard of Project64 which is used for unitialises the emulation by charging the USF, instead of following the process of complete starting of N64. The process of extraction is very intensive because N64 does not have a general format of storage of the music. Files USF can be played in Winamp thanks to an adapted graft, such as 64th Note.

The basic structure of a file USF is a under-format of PSF.
