Digital
AES Audio Analyzing
Sencore Hands-on Tech School
T1
Day: 8:00 am - 5:00 pm
As
more and more digital audio equipment and signals become
commonplace, it becomes imperative to understand digital
audio, how to test its performance and troubleshoot problems
when they occur.
This
comprehensive training course provides a simple approach
to teaching the theory of digital audio, and is filled with
hands-on activities to either get you started or improve
your current digital audio analyzing comprehension and testing
abilities. The class is structured with segments of instructor
presentation, followed by pertinent activities to round
out your understanding of digital audio. The activities
use Sencore instruments, such as the DAG5161 Digital Audio
Generator and the DA795 Digital Audio Analyzer.
What
You Learn:
Tech Theory: You will learn all the terminology regarding
digital audio. You will understand how a digital audio signal
is constructed and organized into a standard signal format.
You will become familiar with the different digital audio
interfaces. You will learn how digital audio levels are
measured and how they relate to digital word values. You
will learn how audio performance can be compromised in a
digital format by digital audio equipment and systems.
Tech Procedures: You will learn hands on procedures
to measure the bit status and parameters of a digital audio
signal. You will learn procedures to monitor the audio within
the digital signal with headphones and a scope. You will
learn procedures to fully performance test a digital audio
signal and digital audio equipment. In all, you will learn
effective methods to diagnose digital audio equipment problems
and signal performance issues.
Tech Tools: You will learn how to generate digital audio
test signals using a signal generator. You will learn how
to use a digital audio analyzer to fully analyze the status,
levels, and channel status bits of any digital audio signal.
You will learn how to use a digital audio analyzer to test
signal performance using THD, frequency, jitter, and signal
lock tests. You will learn how to use a digital audio analyzer
to test digital audio equipment for signal distortion, jitter,
latency and transparency.
