The Inspiron™ 1520 / 1521 system comes with an audio solution that is a major upgrade from the existing AC '97 standard. The Intel® High Definition (HD) Audio technology is also known by the code name Azalia. The actual audio chipset on the system is the SigmaTel® STAC9205.
Intel HD audio not only provides an enriched playback experience but is intended to deliver a better quality input for voice and communication applications. The higher-quality audio is possible in part to an upgraded architecture and increased bandwidth that allows for 192 kHz, 32-bit, multichannel audio and support for evolving high-quality audio formats.
