Noise cancellation at vs1063a

Hello VLSI engineer, I am using the vs1053-vs1063-equalizer-130 patch at vs1063a. When I listen to the voice through the microphone, I can not clearly hear the person's voice due to ambient noise such as the sound of the machine, wind, or car etc. Is it possible to remove the ambient noise at this c...

Re: A question for "VS1063A APPNOTE: AEC WITH VS1063A"

Hello, VLSI,

Could you reply this AEC question?
Whether is is possible or not using the AEC only in the vs1053b_vs1063a_equ?

Thanks.

A question for "VS1063A APPNOTE: AEC WITH VS1063A"

Hello, I have a question for "VS1063A APPNOTE: AEC WITH VS1063A" Inside the vs1063an_aec.pdf, it is written that have to use VS1063a Patches v1.60 or higher.But when using the vs1053b_vs1063a_equ only, are there any problem of using the function of Acoustic Echo Cancellation with VS1063a? Our device...

Questions for VS1053b/VS1063a Equalizer ver1.50

Hello VLSI, I just changed the vs1053b_vs1063a_equ code from ver1.30 to ver1.50 on my device. I could hear microphone sound at ver1.30 but I couldn't hear microphone sound at ver1.50. Could you let me know how could I change my code for ver1.50 if I missed instruction guide? I have one more question...

Noise from microphone with VS1063A

Hello VLSI engineer. I attached recording files from microphone (Sample1.m4a, Sample2.m4a). Our device use vs1053-vs1063-equalizer-130 patch. The recording are marred by some noise. These are setting in the VS1063A. WriteSci(SCI_CLOCKF, 0x8BE8); WriteSci(SCI_AICTRL0, 0xBB80); WriteSci(SCI_AICTRL1, 0...

Re: Amplitude issue at New sine test

Hello, Pasi, Thanks for your quick answer. I tested other values than 0x8000 for new sine test. It is work. My product use the 7-band equalizer so we have to use the 7-band sine signal for testing. // 64, 160, 400, 1000, 2500, 6250, 15600 Hz Hello Henrik, Could you send the necessary parameters for ...

Amplitude issue at New sine test

Hello, VLSI engineer. I have a problem at new sine test. In normal state(with vs1053-vs1063-equalizer-130), below sine test program is exactly worked but below new sine test program does not work. The problem is that new sine test's amplitude is very small. I attached captured image. Could you suppo...

VS1063 Power Consumption

Hello, VLSI team I've checked power consumption at our product which is used VS1063, external microcontroller and vs1053-vs1063-equalizer-130 plugin. The VS1063's spend around 40mA power at running state. It is a big value. I found Power Consumption chapter 5.4 at vs1063a datasheet. But I can't unde...
