Previously a basic record/play system using a hard drive was considered. This relied on a table linking time codes in the recording with physical addresses so that the drive would access audio data blocks in the right sequence slightly ahead of when they were needed. In that way a time base corrector could present the samples in an unbroken sequence at the correct sampling rate to a DAC. The mechanical timescale of a legacy medium such as tape or film has been replaced by a logical timescale.
IP is delivering unprecedented flexibility and scalability for broadcasters. But there is a price to pay for these benefits, namely, the complexity of the system increases significantly as we add more video and audio over IP.
To get the best out of a microphone it is important to understand how it differs from the human ear.
The random-access characteristic of the disk drive made it attractive for audio editing purposes and when drive prices fell as computers became popular the attraction was even stronger.
In the high stakes world of auto racing, every second counts so whatever a team can do to improve its performance, both on and off the track, is put into play. For the highly successful Corvette Racing team, which competes in endurance races that last 24 hours to the finish, it’s secret weapon is reliable two-way communication between its drivers and crew.
We move on to looking at developments in noise cancelling technology and the role it can play in achieving clarity and comfort within headsets for intercom use.
