About MMV Files

An .mmv file is an audio file saved in the MMSSTV Audio File (MMV) format, a specialized format used by the MMSSTV software for receiving and recording slow-scan television (SSTV) transmissions. MMV files store the audio signals that encode SSTV images, rather than conventional music or spoken audio. Amateur radio operators commonly use the format to capture SSTV transmissions so those receiving it can later decode the audio into images.

MMV files are most often created by MMSSTV during radio reception sessions, but may also be shared between hobbyists for decoding or analysis. They remain popular among amateur radio enthusiasts and SSTV hobbyists interested in preserving or reviewing received transmissions.

• Converting to MP3: Converts the recorded SSTV audio in an MMV file into a widely supported format that can be played on most devices and media players, though lossy compression may slightly affect decoding accuracy.
• Converting to AAC: Converts the SSTV audio to a more efficient format, producing smaller files while maintaining good audio quality and compatibility with modern devices and streaming platforms.
