DS Microphone Speak / Blow
Does the No$GBA have a microphone support?
Basically, this emulator has a microphone support system. However, some users are able to use this feature while the others find their system useless. They still need to download other applications like Audacity to make use of this part.
I want to set my No$GBA sound to mute. How can this be made possible?
You just have to choose “None” under the Sound Output Mode which you will find in the Emulation Setup under the Options menu.
However, you need to consider that there are some games that are dependent to sound. If you turn this off, your emulator might freeze and will not work properly.
AGB (Gameboy Advance) Sound
The Advance (GBA) gaming sound subsystem sometimes may seem like black magic, as the lack of documentation for this particular machine part is huge. Even more, getting accurate data on the older gaming handheld is a big problem. As a result any will have small or no sound featured in their homebrew and demo projects. We try to help by providing * Unofficial *, a comprehensive, and (as much as possible) GBA sound system (GBAS) precision specification. It is allowed that the reader will know the other basic functions of the GBA and know how to program C.
GBAS is a big step forward for its older brothers, as it now has two pulse width modulators (PWMs) that act as digital-illuminated converters. It adds up to 4 soundcards present in the previous Gameboys. One important improvement in the sound system is that the 3rd channel wave is now in the bank, allowing the dynamic wave to be activated seamlessly.
The orriginal Nintendo Gameboy Advance BIOS also includes many sound-related features for reproducing MIDI notes and playback of music. GBA BIOS file or a compatible placeholder may be included in the future.
