What is an IDSP file?

IDSP files mostly belong to IDSP Decoder. About IDSP files: These are audio data containers used mostly to store game sound effects and music data. In many cases, they hold samples and sound sequences that are processed by specialized decoders such as the IDSP Decoder used in titles like Super Smash Bros. Brawl.
Some IDSP files follow a RIFF structure, meaning that the audio data is organized similarly to standard waveform files. This allows tools like Sound Forge Pro to work with them. For more details on one of these tools, visit the MAGIX website.

IDSP file format details:

The file format determines how the data is stored in the file. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Our evaluation of the IDSP files looks like this:
