Role of Audio Mixer
With
the changing environments, the noise level of the surrounding also
varies, and the human voice also adjusts accordingly. The human brain
automatically regulates the speaking level of our voice based on the
surroundings. That’s why VHF radio is built to adjust the Squelch,
which can fine-tune the noise interruptions up to a rational level.
When you are working in an extreme situation, wind, engines, rain, or
even breathing can be captured by the usual microphone, which forces
to loud speaking becomes necessary to overcome background noises.
The
iriSound is available with new DSP software AVAD (Adaptive Voice
Activity Detection), which makes it possible to capture and
concentrate on a single channel only. So, even after huge noise in
the background of compound scenarios, the microphone will not start,
and will frequently activate by a single word of the customized
channel.
AVAD
examines microphone 6000 times in a second, which maintains speech
level in the presence of environmental noise. The squelch level
automatically sets to activate the microphone, when it listens to the
loudest voice and ensures background silence in amid of speech.
Moreover, with automatic Squelch adjustment, it also analyzes the
speech pattern of users for realizing the need for the background
noise adaption. In the direct wind, AVAD is tested at sea at 40 Knots
that proved it to clearly capture low-level whispering and transmits
outstanding speech in high-volume noise as well.
The
iriSound has 30% of the reference level, which means, to activate the
microphone, you should match the squelch level, and you need to
amplify the speech 30% higher than the background sound. The
reference level can be customized according to the requirement of
extreme surroundings.
In
the Nutshell
An
audio mixer is a powerful tool used to record and amplify the voice
or sound. But when it comes to the usage by the professionals,
Portable Audio
Mixer is
preferable that can be used in mobile working conditions. IWCS offers
iriSound, professional audio mixer available with varying intercom
ports that are appropriate for mission-critical uses.
