The bridge card included the 68882 FPU to improve floating-point performance. The NuBus card was mounted horizontally above the motherboard. To cut costs, the IIsi's video shared the main system memory, which also had the effect of slowing down video considerably, especially as the IIsi had 1 MB of slow RAM soldered to the motherboard.
In their testing, MacWorld described the video performance of the Quadra 630 as "mediocre". [2] CD-ROM: Models equipped with a CD-ROM use the Apple CD 300i plus, a 2×-speed SCSI drive capable of reading 656 MB and 748 MB data CDs as well as audio CDs. The caddy tray from the Quadra 610 is replaced with a tray-based loading mechanism.
Pitch scaling is the opposite: the process of changing the pitch without affecting the speed. Pitch shift is pitch scaling implemented in an effects unit and intended for live performance. Pitch control is a simpler process which affects pitch and speed simultaneously by slowing down or speeding up a recording.
Sound quality is typically an assessment of the accuracy, fidelity, or intelligibility of audio output from an electronic device. Quality can be measured objectively, such as when tools are used to gauge the accuracy with which the device reproduces an original sound; or it can be measured subjectively, such as when human listeners respond to ...
The IIfx includes two special dedicated processors for floppy disk operations, sound, ADB, and serial communications. [3] These I/O chips feature a pair of 10 MHz embedded 6502 CPUs, which is the same CPU family used in Apple II machines. [4] The IIfx uses SCSI as its hard disk interface, as had all previous Macintosh models since the Macintosh ...
Many audio components are tested for performance using objective and quantifiable measurements, e.g., THD, dynamic range and frequency response. Some take the view that objective measurements are useful and often relate well to subjective performance, i.e., the sound quality as experienced by the listener. [12]
Audio Interchange File Format (AIFF) is an audio file format standard used for storing sound data for personal computers and other electronic audio devices. The format was developed by Apple Inc. in 1988 based on Electronic Arts' Interchange File Format (IFF, widely used on Amiga systems) and is most commonly used on Apple Macintosh computer systems.
The Personal Video Recorder (PVR) range uses an on-board MPEG/MPEG-2 encoder to compress the incoming analogue TV signals. [2] The benefits of using a hardware encoder include lower CPU usage when encoding live TV. The first WinTV-PVR product was the WinTV PVR-PCI, launched in late 2000 and not receiving any driver updates since February 2002.
