assert failed: void audio_tools::ConverterAutoCenter::begin(int, int, bool) BaseConverter.h:211 (p_converter!=nullptr)

[hash6iron]

Hello.

I updated AudioTools at 1.1.0 version. When I do BEGIN to use AnalogAudioStream the following error is returned from debugger. In previous versions this problem was not appear never.

assert failed: void audio_tools::ConverterAutoCenter::begin(int, int, bool) BaseConverter.h:211 (p_converter!=nullptr)

This is my initialize code where failed.

AnalogAudioStream in;
auto cfg = in.defaultConfig(RXTX_MODE);
cfg.sample_rate = 44100;
cfg.bits_per_sample = 16;
cfg.channels = 2;

// Here the code failed (line 598 in TAPrecorder.h)
in.begin(cfg);

Is a bug?
Thanks in advance.

Debug information from ESP32

I check with this code below, and failed too.

AnalogAudioStream in;
AnalogConfig anCfg;

// Here the code back to fail.
in.begin(anCfg);

[hash6iron]

In previous versions I have been using duplex mode and working, why not now?

[pschatzmann]

Nop, the ESP32 Analog API could never do this!

[hash6iron]

Sorry I understand, but I means that I have been using until to update at 1.1.0 using AnalogAudioStream class with this parameter RXTX_Mode and working well.

I don't know if is a real duplex or not because I'm reading and write at differents moments, but if I don't configure RXTX_mode output not works, only input line. Then I have been using input line and later putting all data sound in output line in the same loop for this reason the parameter was RXTX

[pschatzmann]

With what processor ?

[hash6iron]

ESP32

[hash6iron]

@pschatzmann the issue has not been solved, and before I never had problems with this function, please review this because I think there is a bug in version 1.1.0 or severals before.

I try now with this code, and the result is the same, failed. I put a link of a video that I recorded previous that your library was updated to 1.1.0. In the video you can see the devide working with this code that now fails but with RXTX_MODE parameter.
The routine capture audio and later put to output this to monitorize the capturing.

https://youtu.be/-iy3zRe6ag0

AnalogAudioStream in;
AnalogAudioStream out;

auto anCfgIn = in.defaultConfig(RX_MODE);
auto anCfgOut = out.defaultConfig(TX_MODE);


in.begin(anCfgIn);  // The code failed here,
out.begin(anCfgOut);

the debug return this.

@pschatzmann Can you explain me, Why yesterday is working well as you can see in the video and later, after AudioTools updating, the code not working and fail in AudioTools? Please review the error, because the code not working even I'm using RX_MODE

I not need duplex mode, but The code not working when I try to use RX_MODE only. Fails in RX_MODE.

[pschatzmann]

I am sorry, but it is technically not possible that this was ever working!
It might be that you did not get any exception, but this does not change the fact that you try to do something which is not supported!

[hash6iron]

@pschatzmann Yesterday the devide was working well. I only updated your library at 1.1.0 version! You can see the devide working well in RXTX_MODE without any problems, by hours! Do you understand me? But I not need duplex! I only want to read and write in the same loop like before when the device was doing. But the code fails when I do begin at RX_MODE

The board is Audiokit ESP32-A1S

[pschatzmann]

The AnalogAudioStream is using the internal DAC and ADC of the ESP32. To my knowlege the AudioKit does not provide the pins to access this functionality.

I think you want to use the I2SCodecStream and AudioBoardStream that provide the I2S functionality to the ES8388 Codec Chip of the AudioKit.

[hash6iron]

Ok, you are the maximun expert of your library, but I have not changed the code and I have using by weeks this routine without problem, capturing audio from the LINE-IN jack of Audiokit, and later updated library all was failed.

I just checked that TX_MODE fails too.

[hash6iron]

@pschatzmann Please, Explain me why with 1.0.1 version of AudioTools my Audiokit ESP32-A1S works fine!!
