Analog Output to Memory Stream. How to?

[dhionnystrauss]

Dear Prof Schatzmann,
I wanted to greet you and wish you a very successful New Week.
Also, I am trying to obtain analog output directly from my ESP32. Using this code, it is giving a sound output, but it is not sounding correct.

#include "AudioTools.h"
#include "filemanz.h"
AudioInfo info(22050, 1, 16);
MemoryStream musicmanz(Track_3_raw, Track_3_raw_len);
AnalogAudioStream analog;
StreamCopy copierm(analog, musicmanz);

void setup(){
Serial.begin(115200);
analog.begin(analog.defaultConfig(TX_MODE));
analog.begin();
}

void loop(){ copierm.copy();}

Could you please indicate what would be missing? Thank you so much.
I really appreciate it Prof Schatzmann.
Very best regards,
Mit freundlichen Grüßen,
Dhionny Joanhan Strauss

The sketch has the following errors:

• You defined info, but you are not using it anywhere!
• You call analog.begin() twice
• If you use binary data, it is important to let the output class know what the sample rate, channels and bit per samples is. otherwise it just uses the defaut values which are 44100, 2 and 16

Please be more diligent: You should be able to catch this yourself!

Hello Prof Schatzmann,
Thank you. I am trying to pass the Audio Config Info to the Analog Config, I tried this but it is still not passing the Info Config.

#include "AudioTools.h"
#include "filemanz.h"
AudioInfo info(22050, 1, 16);
MemoryStream musicmanz(Track_3_raw, Track_3_raw_len);
AnalogAudioStream analog;
StreamCopy copierm(analog, musicmanz);

void setup(){
auto config = analog.defaultConfig(TX_MODE);
config.copyFrom(info);
analog.begin();
}

void loop(){
copierm.copy();
}

Could you please see what would be missing to pass then the Audio Info to Analog config?
Thank you so much
Dhionny
