"The first has to do with enhancements to how the phone uses its four available microphones. They'll combine spatial recording with noise reduction and AI smarts to isolate voices and enhance the sound recording. The phone will be able to capture audio directionally, tune recording to the phone's front or back, have noise reduction (from 0 to 100%), and even gain adjustment (from -100 to 100%), which is something of a pro feature."
"The X300 Ultra is getting a bigger and smarter top speaker. It will reportedly be nearly 3 times larger with a cavity of 0.8cc. That's around a 167% increase in physical size, per vivo. Flagship phones typically have around 0.3cc to 0.5cc speaker cavities. Vivo has also boosted the amplifier by 20%. The result, per Boxiao, is a nearly 4dB improvement in the lower (bass) frequencies around 300Hz, and a wider high frequency by 3kHz."
"Vivo has reportedly reworked the entire upper right side of the phone to serve as a speaker enclosure and moved the speaker's cavity cover to the bracket. Vivo says it has patented this innovative design."
The vivo X300 Ultra features substantial audio enhancements on both capture and playback sides. For recording, the phone utilizes four microphones with spatial recording, noise reduction, and AI voice isolation capabilities. The camera app includes directional audio capture, front/back tuning options, adjustable noise reduction (0-100%), and gain adjustment (-100 to 100%). For audio reproduction, the device incorporates a significantly larger top speaker with a 0.8cc cavity—a 167% increase from typical flagship sizes. The amplifier receives a 20% boost, delivering nearly 4dB improvement in bass frequencies around 300Hz and extending high-frequency response from 17kHz to 20kHz. Vivo redesigned the upper right phone section as a speaker enclosure with a patented innovative design.
