vs1053

[andynvkz]

You indicated that the stream is audi PCM, but vs1053 does not perceive it

[pschatzmann]

This has nothing to do with A2DP and as far as I know the vs1053 does not support PCM.

I converted this into a discussion because there is clearly no bug in my library.
Did you try to encode the output into a WAV format ?

[andynvkz]

I did not encode the output to wav format, I thought that the data is exactly what comes out, vs1053 (https://cdn-shop.adafruit.com/datasheets/vs1053.pdf)

[pschatzmann]

Please read the specification again: It indicates that PCM and ADPCM is supported by providing WAV!

After all that's exactly what my other projects are about e.g.

• https://github.com/pschatzmann/arduino-audio-tools
• https://github.com/pschatzmann/arduino-vs1053

[andynvkz]

Tell me how and how can I convert this format so that it would be accepted by vs1053?

[andynvkz]

It would be ideal if they added support for this chip to the library

[pschatzmann]

That does not make any sense at all. The A2DP library is part of the AudioTools which provides exactly what you are asking for

[andynvkz]

I just don't understand how to use it

[andynvkz]

how do i get the vs1053 stream to play? from read_data_stream

[pschatzmann]

Use an EncodedAudioStream and define the output to be a VS1053Stream, also provide a WAV Encoder so that the output is converted to WAV.

In the data callback function you just write to the EncodedAudioStream.

Don't forget to open the streams properly...

If you double check the VS1053Stream API, there is even a short cut where the above is done automatically.

[andynvkz]

it's not the volume, something is wrong with the PCM format

[pschatzmann]

So, did you check if the write was processed correctly ?
I would have expected that you extend the error handling in this case...

[andynvkz]

in the title, I indicated that the data is 44100 Hz 16-bit stereo, right? and format PCM or ADPCM?

[pschatzmann]

The data format is 16 bit PCM data with 2 channels usually at 44100 hz: You can find this information in the README, that you were supposed to read before starting a discussion!
I suggest that you also add a check after starting a2dp to verify the effective sample rate with the API

I don't quite understand what you mean with title....

RIFF header

[andynvkz]

Thank you, I will try

Everything worked out great for me, YouTube transmits sound, but how can I make sure that the sound is transmitted when making a call?
