Sr , your library is working like a charm , it was my mistake in receiver of i2s pin assignment , now I can clearly listen the sine tone .

But sir now i change sine generator to microphone input (INMP441) , at receiver their is huge noise . (pre test : i2s webserver is successfully working ) I try with different sampling rate 8000 , 22050 , 32000 , 44100 but no success

below is my sender code

include "AudioTools.h"

include "AudioLibs/Communication.h"

include "AudioCodecs/CodecSBC.h"

I2SStream i2sStream; // Access I2S as stream //ConverterFillLeftAndRight filler(LeftIsEmpty); // fill both channels - or change to RightIsEmpty

uint16_t sample_rate = 32000; uint8_t channels = 2; // The stream will have 2 channels

ESPNowStream now; EncodedAudioStream encoder(&now, new SBCEncoder()); // encode and write to ESP-now StreamCopy copier(encoder, i2sStream); // copies sound into i2s const char *peers[] = {"0C:B8:15:C3:40:68"};

void setup() { Serial.begin(115200); // AudioLogger::instance().begin(Serial, AudioLogger::Warning); AudioLogger::instance().begin(Serial, AudioLogger::Warning); //AudioLogger::instance().begin(Serial, AudioLogger::Info);
auto cfg = now.defaultConfig(); cfg.mac_address = "94:E6:86:04:89:44"; now.begin(cfg); now.addPeers(peers);

// start i2s input with default configuration Serial.println("starting I2S..."); auto config = i2sStream.defaultConfig(RX_MODE); config.i2s_format = I2S_STD_FORMAT; // if quality is bad change to I2S_LSB_FORMAT https://github.com/pschatzmann/arduino-audio-tools/issues/23 config.sample_rate = sample_rate;//22050; config.channels = 2; config.bits_per_sample =32; i2sStream.begin(config); Serial.println("I2S started");

// start encoder encoder.begin(config);

Serial.println("Sender started..."); }

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

is above possible with i2s microphone (INMP441) ?

I2s-> SBC encoder -> espnow -> SBC decoder -> i2S DAC

pschatzmann commented 1 year ago

I don't see any reason why this should not work. Just check the SBC specification about the supported audio values

aqildad-create commented 1 year ago

apology if I am missing document. from were i will get SBC supported audio values ? I google for it but cant find related document ,

And which i2s microphone you use for your testing , i have INMP441 , does this make any difference ?

pschatzmann commented 1 year ago

The INMP441 creates noise on one channel if you use it with 16 bits. So you would need to filter that out or use 32 bits and convert them to 16 bits https://en.wikipedia.org/wiki/SBC_(codec) https://pschatzmann.github.io/arduino-audio-tools/classaudio__tools_1_1_s_b_c_encoder.html

aqildad-create commented 1 year ago

yes , you are correct , when was I testing i2s webserver i get the same nose when was using 16bts , but when I change it to 32 bit then i get clear audio on webserver , Now i am using same 32 bit but still its very distorted in receiver after ESPnow ,

is it necessary to use 16 bit , first use 32 bit and then convert to 16 bit , in web server was using 32 bit and it work fine , same here I cant use use 32 bit directly ?

THS IS SENDER CODE and receiver code is same as communication SBC decoder .

include "AudioTools.h"

include "AudioLibs/Communication.h"

include "AudioCodecs/CodecSBC.h"

I2SStream i2sStream; // Access I2S as stream

uint16_t sample_rate = 32000; uint8_t channels = 2; // The stream will have 2 channels

ESPNowStream now; EncodedAudioStream encoder(&now, new SBCEncoder()); // encode and write to ESP-now StreamCopy copier(encoder, i2sStream); // copies sound into i2s const char *peers[] = {"0C:B8:15:C3:40:68"};

void setup() { Serial.begin(115200); // AudioLogger::instance().begin(Serial, AudioLogger::Warning); AudioLogger::instance().begin(Serial, AudioLogger::Warning); //AudioLogger::instance().begin(Serial, AudioLogger::Info); auto cfg = now.defaultConfig(); cfg.mac_address = "94:E6:86:04:89:44"; now.begin(cfg); now.addPeers(peers);

// start i2s input with default configuration Serial.println("starting I2S..."); auto config = i2sStream.defaultConfig(RX_MODE); config.i2s_format = I2S_STD_FORMAT; // if quality is bad change to I2S_LSB_FORMAT https://github.com/pschatzmann/arduino-audio-tools/issues/23 config.sample_rate = sample_rate;//22050; config.channels = 2; config.bits_per_sample =32; i2sStream.begin(config); Serial.println("I2S started");

// start encoder encoder.begin(config);

Serial.println("Sender started..."); }

pschatzmann commented 1 year ago

You can't use 32bit values with the codec! You can use a FormatConverterStream Class to convert 32 to 16 bits

aqildad-create commented 1 year ago

FormatConverterStream . . give me error

Is their any example were you used FormatConverterStream ?

image

pschatzmann commented 1 year ago

Just read the error message. This class must not have any template!

aqildad-create commented 1 year ago

Sir , please Is their any example were you used FormatConverterStream ?

aqildad-create commented 1 year ago

I try to use ChannelFormatConverterStreamT . It compile but i am getting same nose in receiver . .

ChannelFormatConverterStreamT conv(i2sStream); StreamCopy copier(encoder, conv); // copies sound into i2s

I Also search in your GITHUB repository you never use in any examples this FormatConverterStream for your conversion . can you please share any example related to this ?

Also once you said the latest library also support 24 bit i2s stream and if 24bit values support the codec! , then n ths case may be we don't need conversion ?

Further which i2s microphone you used for codecs ?

I also try some thing like this but it did not help either FormatConverterStream conv(int32_t i2sStream ,int16_t);
