- 22 kHz sampling rate means that the card can only reproduce frequencies
- up to 11 kHz. The GUS's 44.1 kHz sampling rate means that its dynamic
- range has an upper limit of 22 kHz. It takes two sampling points to
- reproduce a wave, so you have to divide the sampling rate by two to get
- the dynamic range. Also, the GUS's DAC is 16-bit, compared to the SBPro's
- 8-bit DAC. With the greater bit-resolution and higher sampling rate, the
- GUS does sound very noticeably better than the SBPro.

- The GUS, like the SBPro, only needs an adapter that connects to the
- joystick port for a MIDI interface. It does not require a separate card.

- The quality of synthesized speech is a function of software, with the

- The GUS *is* a synthesizer that uses "digitized samples to sound almost
- EXACTLY like the real thing." And since it comes with its own RAM, the
- samples can be offloaded onto the card instead of taking up main memory.
- Aside from freeing up memory, the GUS also has a processor to handle
- the tedium of wavetable synthesis, freeing up the CPU. With a card like
- the SBPro, the CPU has to spend a lot of time processing samples and
- feeding the DAC when playing digital music.

- The GUS is way ahead of the SBPro in all areas but one: SB compatibility.
- The GUS is not 100% SB compatible. About 90% of SB/Adlib software will
- run well with the GUS. The other 10% will either not run or will run
- poorly or incorrectly with the GUS. The Ultrasound is a card with
- mind-numbing potential but currently little software support for its
- powerful native wavetable (or wavesample) synthesis mode.
