Thanks Peter for your help...again.

So,
I have used an other code and effectively it works... You have right, I have used the calling code for flac sound and it's why it didn't work.
Just, there is a confusion between sdcs and xcs on Y3 or Y4 pin in the simple code on the first presentation page, and I have had to change it.

That's so good. Very good.
Thanks a lot for this new abality in micropython.

For recording, I will try to find a way for stop noise, and maybe play to spy...

Maybe it could be good to have a simple example with the audioskin on pyboard... I will try to find pins correspondances, and test the quality of this record...

Thanks a lots.
All the best.

yep,

The audioskin use i2C, no pin for headphone. I tried the pin "X22" without success for microphone. So, it looks impossible to adapt audioskin to VS1053...

I tried 200 secondes of duration, and everything is right. So no limitation of time... Wonderfull!

The noise is a little bit problematic for me...
I tried to change gain, adc_gain, ..., without success...
I have cutted a microphone like these singers used, solder wires on other wires for connect it to vs1053... The noise is much more lower.
I can hear a person in a room, if this person speak loud and near the microphone.
But for moment spy isn't possible for me.

Could you advise me for find a microphone more adapted at this situation?
Or do you know if add an amplifer behind the microphone could resolve the problem?

Thanks for all.

This was my setup. The preamp produces a balanced output which the VS1053b can accept for mono recordings. A balanced signal is very noise-immune.

The Behringer microphone was bought for another project. It's a measurement mic and probably not ideal for speech recording.

Hey!!!

I have received the same amplificator, and I have added a good microphone for voice...

That's amazing!!!

The record is perfect!
I can hear clearly a person in a room... Accuracy is awsome.

GOOOOD JOB.

All the best.
