Re: VS1063 play G722 stream

First thanks for the help! I found an interesting effect. When my board is powered on and a new firmware is being written, the stream always starts. Empirically, I found that adding a delay after initialization of vs1063 about 3 seconds also leads to a good result. Initialization is the same as in t...

Re: VS1063 play G722 stream

Hello again. Returned to this project. Now I am using G722 16kHz 64kbit. Sometimes, when I turn on or off the receiving device, the data stream is not decoded correctly and only noise is reproduced. As far as I understand, the receiver is not synchronized with the stream. How should the received str...

Re: VS1063 play G722 stream

Yes, thanks. I have already found a solution. For my case: 1) For transmitter // Set bit 10 of SCI_AICTRL3, the RIFF WAV header is not generated. vs_write_sci(SCI_RECMODE, RM_63_FORMAT_G722_ADPCM | RM_63_ADC_MODE_MONO | RM_63_NO_RIFF); 2) For receiver // header for G722 const uint8_t header[] = { 0x...

VS1063 play G722 stream

Hello! I have a question about working with audio G.722 codec. I have two devices. The data is transmitted over the air between them. It turns out that in order to start decoding on the receiver, I need to first turn on the receiver, then the transmitter. Is it possible for the transmitter to encode...

Re: VS1063 VU meter

Dear Pasi
Great reliability is not required. It is only necessary to track the presence of a signal. And if the audio signal appeared to start encoding.

Re: VS1063 VU meter

I've got one more question. Is it possible to track the amplitude without recording? I will not read data from the data buffer. Just read the status of the audio line. It is necessary to record a signal if it appeared after silence.

VS1063 VU meter

Hello.
I need some information to understand.
I will use vs1063 to record the incoming signal in MP3 file. Will this work with VU meter? In addition necessary record the input signal amplitude. Or VU meter only work for a decoded signal?
