libvitaSAS is easy-to-use SceSas and Audiodec library wrapper with system mode applications support.

• SAS is a library for performing synthesizer processing with software.
• Audiodec is a library for decoding audio data with a Codec Engine.

Loading directly from FIOS2 overlay (for example, loading directly from PSARC archive) is supported. When calling vitaSAS_load_audio_XXX() specify 1 for io_type to use FIOS2 or 0 to use SceIo.

Pitch, panning, envelope processing and digital effects processing can be done. Refer to the sample for usage example.

Features

• While SAS, unlike NGS, uses software synthesizing, it has much smaller memory footprint.
• Theoretically unlimited amount of SAS systems can be created.
• Theoretically unlimited amount of voices per system can be created.
