DH File

What are DH files and how to open them

Are you having problems opening a DH file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your DH files.

What is a DH file?

A .DH file is a David Hanney Chiptune file.

David Hanney Chiptune files store music composed by David Hanney. These files encode chiptune tracks - music using simple sound generators or sample playback in styles typical of older computer or video-game sound systems. They are used for artistic or archival purposes, especially in preserving or replaying Hanney's original music works in their native format.

These files are written by David Hanney or his tools. They hold song data such as note sequences, sound-channel configuration, effects, timing information and possibly custom instruments or waveforms defined by Hanney. They are meant for playback through a compatible player or emulator that understands Hanney's format, allowing the music to be heard as originally intended without conversion to a more common format.

Files in this format begin with the ASCII signature "DSNGSEQU" at offset 0, followed by an "INFO" marker at offset 268, and a "BLK" marker at offset 286. These internal identifiers help software recognise the format and locate metadata and musical blocks within the file.
