Chapter 3: AT Commands Reference
June 30, 2008 AT Commands Reference Manual 3-235

Table3-150 shows the differences between Basic and Advanced audio modes in controlling the

audio.

Audio Setup

The G24 has two audio modes: 'Basic Audio' and 'Advanced Audio'. Each mode has a different

behavior and a set of relevant AT commands.

Figure 3-3 describes the two audio modes, switching between them and the AT commands related

to each mode.

Basic Audio Advanced Audio
Path Paths are set automatically
(upon interrupt). Paths are set manually. All routings are
available; any microphone with any speaker
for each type of sound (voice, keypad, ring,
etc.).
Gain There are two types of
gains: phone (voice,
keypad) and ring.
There is a matrix of gains: a different gain is
saved for each type of sound through a
specific speaker.
For example, one volume level for rings
through the speaker and a different volume
level for rings through the transducer.
Therefore, there will be 16 different volume
levels, which is the product of the number of
output accessories (speaker, headset speaker,
transducer and digital output) and the
number of audio tones (voice, keypad, ring
and alert).
Algorithm Algorithms are set by
ATS94 and ATS96. Algorithms are set by AT+MAFEA T.
