.dls File Extension

Developer: Interactive Audio Special Interest Group (IASIG)
File type: Sounds File
You're here because you have a file that has a file extension ending in .dls. Files with the file extension .dls can only be launched by certain applications. It's possible that .dls files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .dls file?

The DLS file extension is a data format known as Downloadable Sounds File. DLS files are audio files that contain sounds of instruments, regions, articulations, and the samples themselves that can be played back using a MIDI input device. These files are Roland GS MIDI sound set and based in the Interactive Music Architecture. There are three current versions of the DLS standard namely DLS Level 1 and DLS Level 2 and Mobile DLS. DLS Level 1 format provide files compatible with the DLS synthesizer architecture level 1 while DLS Level 2 files are compatible with the DLS synthesizer architecture level 2. Mobile DLS format has reduced feature set and memory requirements, for mobile phones. They are related to the SoundFont format created by Creative Labs. Files in DLS format can be opened with SimpleSynth in Mac operating systems. For Microsoft Windows based systems, they can be opened with FMJ-Software Awave Studio.

how to open a .dls file?

Launch a .dls file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .dls file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .dls files aren't yet associated with it. In this case, when you try to open a .dls file, you can tell Windows which application is the correct one for that file. From then on, opening a  .dls file will open the correct application.

FMJ-Software Awave Studio

FMJ-Software Awave Studio

Awave Studio 10.6 is a music-oriented software that lets you convert your audio files, edit and process your audio and create music. It is also a multi-format audio player. It provides customized “instrument banks” that come along with your MIDI files. You can edit your sound by applying effects, fade in and fade out, re-sampling, normalizing amplitudes, etc. It can do instrument editing for your sound card, soft-synth plug and synthesizer. It runs on Windows 7, Windows Vista and Windows XP. It can read 290 formats and write 135 formats. Some synthesizers may use formats or file systems that are unrecognized by Windows, but Awave Studio reads them by directly communicating with the hardware. It can recognize formats from instruments by Akai, Korg, Yamaha, Roland, Ensoniq, Creamware, Kurzweil, Native instruments and many others. Aware Software Synthesizer lets you do real-time auditioning of your instruments. The Batch Conversion Wizard allows conversion of large numbers of files with optional effects. It supports up to 32bit data, and automatically converts lower precision source data to higher precision to avoid quantization errors and for audio fidelity. Instrument Processing Wizard avoids repetitive editing on multiple instruments. MIDI Processing Wizard lets you transpose notes and change tick rate. It has graphical editors for your instrument parameters.

a word of warning

Be careful not to rename the extension on .dls files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .dls. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
