“foo_input_ds” is a slight typo for foo_input_dsf or foo_input_dts, which are third-party component plug-ins for the popular Foobar2000 audio player. Based on the “ds” abbreviation, you are most likely referring to one of two things: 1. The DSD / SACD Decoder (foo_input_sacd or foo_input_dsf)
If you are trying to play Direct Stream Digital (DSD) or Super Audio CD (SACD) files, you are looking for the Super Audio CD Decoder plug-in.
What it does: It allows Foobar2000 to natively read, decode, and play high-resolution audiophile formats including .dsf, .dff, and SACD .iso images.
How it works: It feeds the 1-bit DSD stream either directly to a DSD-compatible Digital-to-Analog Converter (DAC) using ASIO/DoP, or translates it into standard PCM audio if your computer hardware doesn’t natively support DSD.
Where to get it: The project is open-source and actively maintained via the SACD Decoder SourceForge Repository. 2. The DTS Audio Decoder (foo_input_dts)
If “ds” was a typo for “dts”, you are looking for the DTS Digital Surround Decoder component.
What it does: It decodes multi-channel cinema surround sound formats (like .dts and .dtswav files) into a format your computer can play.
Where to get it: The official plugin is managed by developer kode54 and is downloadable directly through the Foobar2000 Components Repository. How to Install These Components in Foobar2000
If you need to install either of these components to fix an unplayable audio file, follow these quick steps:
Download the plugin package (usually a .zip file or a file ending in .fb2k-component).
Open Foobar2000 and open the Preferences panel by pressing Ctrl + P. Click on the Components category on the left sidebar.
Click the Install… button at the bottom right, select your downloaded file, and click Apply.
Restart Foobar2000 when prompted, and your files will now be playable.
