1.
Obtain Hardware and Software
– Speaker characterization and tuning are performed
using the
PurePath™ Console 3
software. The
TI Learning Board
and the
Smart Amp
Target EVM
are needed in order to fully evaluate and develop with
Smart Amp
. Refer to
Section
2.
Plan for Development
– Developing
Smart Amp
based systems for the first time can be
different than working with conventional amplifiers. Information obtained during the
speaker characterization process often leads to changes to the speaker or enclosure to
maximize output and quality. See Section
3.
Obtain Speaker Parameters
– The next step is to understand the characteristics of the
speaker to be tested. This is covered in Chapter
. Once a speaker is characterized, the
ppc3 file obtained from this step will be used on the next step.
4.
Tune Speaker
– Once the speaker data is obtained, a speaker can be tuned using the
Learning Board
or the
Target EVM
by importing a ppc3 file. Refer to Chapter
5.
End-system Integration
– Smart Amp fundamentally shifts how audio systems are
designed. Using the Smart Amp tool set, a designer gathers an in-depth understanding of
speaker electro-mechanical, thermal and acoustic parameters. Based on these
parameters, Smart Amp algorithms deliver high peak voltage and current to the speaker
while protecting the speaker from excessive heat or movement. Increased voltage and
current levels lead to changes in the system power design. For these reasons it is
important to understand the power supply requirements early in the design. This is
covered in Chapter
. Software implementation is discussed in Chapter
