24 Bit to 16 Bit FormatConverterStream Not Working for Me

[frohro]

Hi @pschatzmann ,
I'm working up to taking 24 bit I2S data from a PCM1808 to USB using the your fork of the Adafruit_TinyUSB library. I am working on the format conversion just now. I took your example from the Wiki here and it works great for 32 bit to 16 bit conversion, but changing the 32 to 24 I get this:

Here is my code:

#include "AudioTools.h"

SineWaveGenerator<int24_t> sine_wave;                   // subclass of SoundGenerator with max amplitude of 32000
GeneratedSoundStream<int24_t> in_stream(sine_wave);     // Stream generated from sine wave
CsvOutput<int16_t> out(Serial);                         // Output to Serial
AudioInfo from(48000, 2, 24);                                           
AudioInfo to(48000, 2, 16);                                           
FormatConverterStream conv(out);
StreamCopy copier(conv, in_stream);                     // copies sound to out

void setup(){
  Serial.begin(115200);
//   AudioLogger::instance().begin(Serial, AudioLogger::Info);  

  sine_wave.begin(from, N_B4);
  in_stream.begin(from);
  conv.begin(from, to);

  out.begin(to);
}

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

What am I doing wrong?

Thanks,

Rob

Strange, I just tried your sketch an a ESP32 and RP2040 and I am getting this

Thanks @pschatzmann ! I don't know what gives. I copied the folder to another computer and rebuilt it there, and now it works for me, too. I'll try and figure what might be going on with the other computer. I have been using VScode and PlatformIO for both of them. I'll let you know what it was if I can figure it out.

The best I can figure is I was actually building the wrong code last night, so I'm pretty sure it was my dumb mistake. :-)
