What is a DLS file?
A .DLS file is usually a Downloadable Sounds sound bank. It uses the RIFF format. Microsoft created this format for the DirectMusic API and the Microsoft GS Wavetable Synth. These files contain digital audio samples and instrument definitions. Sometimes, .DLS files are electrical schematic diagrams created by SEE Electrical from IGE+XAO.
How to open DLS files?
You can open .DLS sound banks using audio software like Awave Studio or Polyphone. If the file is an electrical diagram, you must use SEE Electrical.
Best practices and troubleshooting
Because .DLS has multiple possible meanings, we recommend using viewer.online/dls to identify the actual format of the user's file. If your audio software cannot read the file, it might be a schematic diagram instead of a sound bank.
Software and tools
Common tools for editing or converting .DLS files include Awave Studio, Polyphone, and SEE Electrical for diagrams.
Summary
viewer.online/dls analyzes .DLS files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. Because most .DLS files use the known RIFF format, viewer.online/dls can safely open and display them online, eliminating compatibility problems.
