Audio for the NewMedia CD
Article Abstract:
The process NewMedia went through to develop its ToolGuide CD-ROM is presented in detail and illustrates the challenges of including digital sound in CD-ROMs. Typically, CD-ROM's limited bandwidth allows audio specifications of no more than 8-bit 22KHz, so production envelopes are tight. NewMedia reports it is possible to obtain good quality out of 8-bit 22KHz sound, but the process is both challenging and complicated. Steps in the process include recording procedures, processing and mixing, addressing audio for video challenges and managing sample-rate and bit-depth converting. Overall, NewMedia discovered that while it is not possible to make 8-bit sound as good as 16-bit, savvy development will minimize the impurities and noise that can occur if necessary precautions are not taken.

Getting real with RealAudio
Article Abstract:
Progressive Networks' RealAudio 1.0 sound audio software compresses audio files to stream Web page sound in real time and eliminates the standard dead-air download. Users can utilize RealAudio to process CD audio. To do so, users should use a high-quality microphone and record in a quiet area. To address the overall level, users should avoid digital distortion by reducing RealAudio's frequency response to 4kHz. Users can normalize the file to increase the overall level. A Waves plug-in, gate downward expander and compressor limiter combination, and C1 can be used to optimize the dynamics of the file. The RealAudio encoder changes files with sample rates of 48kHz or 44.1kHz, however users can obtain better siblants by using Waves' WaveConvert application to convert to 8kHz.

Windows 95. PC multimedia grows up
Article Abstract:
Microsoft says its Windows 95 operating system will be 48% faster than Windows 3.x. The new system has a substantially upgraded GUI, and it has better file and resource management. Its Plug and Play capability makes configuration of peripherals simpler, and it features built-in networking, as well as a set of 32-bit applications. The hardware configuration has been kept to a minimum but may require 16MB of RAM to run effectively. Limitations associated with DOS have been minimized, and unlike the cooperative multitasking Windows 3.x, Windows 95 offers pre-emptive multitasking. Its multithreading feature is very sophisticated and can substantially improve a machine's throughput. The interface is influenced by the Macintosh and includes built-in utilities.
