Internal Soundcards

These are the internal PC soundcards that I currently own (ISA).

Advanced Gravis UltraSound with 1MB RAM [Rev. 3.4]

  • Music/Digital capabilities: up to 32 voices Gravis GF1 16-bit/44.1KHz Playback, 8-bit/44.1KHz Recording (Stereo) *
  • Other: 16-bit recording daughterboard upgrade
  • Connections: Speaker-out, Line-out, Mic-in, Line-in, Game/MIDI-port
  • Interface: ISA (16-bit)
  • Year of introduction: 1991

*    Playback 44.1KHz up to 14 voices. Only 19KHz with all 32 voices enabled. Recording can be 16-bit 44.1KHz with optional daughterboard. Note that the UltraSound PnP is based on the AMD Interwave chip instead of the Gravis GF1 and is the only UltraSound card able to play back at 44.1KHz with all 32 voices enabled.

*    This is a custom-built Sound Blaster 2.0 clone specifically designed with low-noise in mind. It lacks the game port as well as line/mic inputs but does have a PC-speaker and CD-Audio header and separate volume buttons for all sound sources at the back. The card is based on a real Yamaha OPL2 chip and an Atmel Atmega328P microcontroller.
