The Signal Protocol C Library is a C-implementation of the Signal protocol used by the Signal messenger from Whisper Systems. Adding this with WebRTC/Opus as sink/source to the ESP-ADF would allow to stream audio/video securely and in high quality between the ESP32 and the Signal messenger on Smartphones and Desktops (e.g. ESP32 as door station, ...).

This ESP32-LyraT V4.3 board is quite awesome!
I know it does not have allot of codecs (yet). This would be a great platform to make a VoIP phone.
We use SIP modules, and their cost is quite high at $150 per module. The cost savings would be insane to switch to the ESP32.

It looks like only ES8388 is supported.
Are there any plans to support other codecs, like WM8978 found on some ESP32 boards?

Hi,
I was playing this example play_mp3_dac on ESP32 board. It works. However, I have some questions:

The macro I2S_STREAM_INTERNAL_DAC_CFG_DEFAULT() is defined as:

#define I2S_STREAM_INTERNAL_DAC_CFG_DEFAULT() {                                     \
    .type = AUDIO_STREAM_WRITER,                                                    \
    .i2s_config = {                                                                 \
        .mode = I2S_MODE_MASTER | I2S_MODE_DAC_BUILT_IN | I2S_MODE_TX,              \
        .sample_rate = 44100,                                                       \
        .bits_per_sample = 16,                                                      \
        .channel_format = I2S_CHANNEL_FMT_RIGHT_LEFT,                               \
        .communication_format = I2S_COMM_FORMAT_I2S_MSB,                            \
        .dma_buf_count = 3,                                                         \
        .dma_buf_len = 300,                                                         \
        .intr_alloc_flags = ESP_INTR_FLAG_LEVEL2,                                   \
    },                                                                              \
    .i2s_port = 0,                                                                  \
}

The sample rate is set to sample_rate = 44100. However, this causes problem when the MP3 file is not 44.1 KHZ. It plays the Music much faster if it was not 44.1KHZ.

My question is: how to dynamically set the sample_rate to be exactly as the Mp3 file sample rate without hard-coding it.

One another question: after calling audio_pipeline_run(pipeline_);. The Mp3 starts till it ends. How can I have control over it? Does it open some kind of thread?

• when I build the pjoject, but i find the error log :

My ESP32-LyraT board does not work from a battery. It will not charge nor run. Anyone else having this problem?

1. What did I do:
   I am trying to play mp3 file from my sd card. Using my own ESP-WROOM-32 module. First, I modified the I2S pins to working with my hardware, it works on play_mp3_dac example. Next, I wired the SD card same as module esp32-lyrat and removed the element codec_chip in pipeline_sdcard_mp3 example's main file.
2. Problem:
   The SD card is mounted success. But mp3 file can't be read.

It returns:

Ive got my comport setup in menuconfig but always seem to get the following error. Menu config is COM10

A fatal error occurred: Failed to connect to ESP32: Invalid head of packet ('\x08')

i want to know can anyone planning to add UDP Support alternatively then HTTP

git下最近的adf编译运行里面的demo有几个pipeline_sdcard_mp3，pipeline_sdcard_wav等几个demo没有播放出音乐，没有任何错误信息，就是没有声音，另外的一些demo例如element_sdcard_mp3，pipeline_bt_sink都能够通过耳机听到音乐，是配置跟之前有什么不同吗？adf是git的最新的，idf默认的是c2b39f4a5f4没有声音，乐鑫官网上的举例是ca3faa61 也没有声音，是需要其他配置吗？使用之前git的都能够听到音乐的。

蓝牙音频的i2s传输想改32位输出到dac上，在历程上改了32位，用示波器测试计算还是16位，bck为1.4m左右，理论应该为2.8m。能提供一下怎么更改吗

Hello, so I just received my ESP32-LyraT v4.3 today, and I tried going through the Getting Started with the LyraT and noticed my board wasn't behaving as expected.

When I plug in both MicroUSB ports to two USB ports on my Mac, I don't see the Standby green LED light up (neither the battery LED). I do see the red Power LED light up when I turn the power on though. Additionally, I don't see the computer recognizing the serial port that the LyraT is connected to, however when I connect to my ESP-WROVER-KIT board I see the port just fine. Is my LyraT board defective?

Is there a plan to build a DAC driver for i.e. the Project Minimum Design https://esp-adf.readthedocs.io/en/latest/design-guide/project-design.html#project-minimum ?
Would this added to audio_hal_codecs_default ?

Hello,

The readme page says that LyraT will be supporting Bluetooth A2DP and HFP.

I see that the Bluetooth A2DP sink support has been added - fantastic!

When will the Bluetooth HFP support become available? HFP is required by my product.

Thanks!

If we have Bluetooth Speaker then we do not need I2S/DAC to play sound. In this case how to connect ESP32 with a Bluetooth Speaker and send streaming Audio File, pause and resume it.
Thank you

Hello,

When running the play_mp3 on esp32-lyrat v4.3, I get the following error. I can't hear any audio even though I connected an apple headphones to the PhoneJack.

Hi,
The answer seems obvious but I just want to double check. Does esp-adf basic features such as decoding Mp3 from an external SD card and playing it using the internal DAC (GPIO 25,26) available with the original ESP32 (I do not have Lyrat board ).

Hello,

I tried running the pipeline_raw_http by following the instructions in readme file.
I connected both the laptop and the lyrat board to the same wifi network and also specified server URI as "http://192.168.0.248:8000/upload". Also on another terminal I ran the "python server.py" and I get a message saying "Serving HTTP on 0.0.0.0 port 8000". When I press the REC button and release it, after few seconds I get the error below.

Hello Team Espressif,

Recently we have brought a ESP-LyraTD-MSC which works excellent with IDF. I have a technical doubt around which I have tried and read everything but nothing worked out.

I think the issue is with I2C Driver. Can you please look into it and suggest if we are missing on something obvious?
No example works from ADF, for instance you can refer to following logs for Play_MP3 example project given in repository esp-adf/examples/get-started/play_mp3 :

这是为什么呢，其它的例程都可以，就这个不行。

编译例程的时候出现这个错误:
/home/esp8266/Desktop/esp/esp-adf/components/audio_stream/./fatfs_stream.c:39:22: fatal error: wav_head.h: No such file or directory

求提供关于i2s的SCLK和LRCK的时钟频率由外部提供的方法，我们公司准备接上esp32传蓝牙音频，问题是我们的SCLK和LRCK由自己的DSP芯片提供，历程上esp32的音频好像只能选择由esp提供，能否由外部提供i2s时钟信号，如何修改，万分感谢能提供帮助的

最近在lyrat_v4.2上测试录音，发现编译这个例程运行的时候录音只有10秒（理论上应该是20秒的），而且通过其他播放器播放的时候播放速度比录的声音要快，这是什么原因啊？

Hello,

What I want to know is that esp32-lyrat-v4 can use the esp-adf framework to record while playing?

Thank you.

In Play_mp3_dac example:

This line seems to be blocking. The loop works for 3 iterations and then stops at this lines. I tired to change the third parameter from portMAX_DELAY to 10 and it does not block anymore but the MP3 is played with wrong clock for few seconds (it is logical to cause this problem since the bit/sample rate has not been fetched yet).

How can I prevent it from been blocked ?

现在ｓｄｋ提供录音ｄｅｍｏ只支持44.1ＫＨｚ格式下录音，不开放１６ｋＨｚ录音，我查看了源码，采集数据是可以做到１６ｋ录音，但是ｗａｖ信息头文件还是写到４４．１ＫＨz,导致录音文件播放出错，后来追踪到贵司把该部分代码封装到静态库，这样子无法修改ｗａｖ头文件，１６ＫＨｚ和８ＫＨｚ是非常常用的格式。，希望贵司工程师能够开放支持修改ｗａｖ头文件信息。

你好！运行pipeline_bt_sink蓝牙播歌例程发现bug：不能通过四个触摸按键控制手机播放、暂停、切换；而在苹果手机上测试并没发现此问题！这是例程bug还是SDK bug？

Hi,
I am trying to mimic the play_mp3_dac example (which works correctly Commit: f6d007a ). I am almost sure that I have done everything as it was written in the example. However, after the Mp3 is played and finished, I call :

        audio_pipeline_terminate(pipeline_);
	audio_pipeline_remove_listener(pipeline_);
	audio_event_iface_destroy(evt_);
	audio_pipeline_deinit(pipeline_);
	audio_element_stop(i2s_stream_writer_);
	audio_element_deinit(i2s_stream_writer_);
	audio_element_deinit(mp3_decoder_);	

At this line:
audio_element_deinit(i2s_stream_writer_);
The program stops responding. I went into audio_element_deinit code and I found that the problem is exactly at this line:
audio_element_wait_for_stop(el);

I commented it out and everything worked fine. However, I am sure that at some points my program will explode because it is trying to free something while it is still working.

May you please give me any hint why does this happen?

Thank you very much!

The ST STA333BW is a 2x20W I²S power-amplifier IC around 3.50 €. Besides power-supply and 4 inductors it only needs 1 electrolytic capacitor, 2 THT capacitors, 22 SMD capacitors and 9 SMD resistors for a stereo configuration.

It provides the followiing 3 power output configurations:
– 2 channels of ternary PWM (2 x 20 W into 8 Ω at 18 V) + PWM output
– 2 channels of ternary PWM (2 x 20 W into 8 Ω at 18 V) + ternary stereo line-out
– 2.1 channels of binary PWM (left, right, LFE) (2 x 9 W into 4 Ω +1 x 20 W into 8 Ω at 18 V)

This issue is meant as a starting point to implement ESP-ADF-support for more powerful power-amplifiers than on the LyraT boards.

When I used bluetooth demo to play music, I ran into the following problem.And I can't hear anything.

试了好多次 ，百度语音提示都是提示“抱歉，我不知道你说了什么”，请问调试的话应从什么方向入手呢？

Hi,
Is it possible to use ESP-ADF from Arudino IDE with other Arduino libraries? I used to use ESP-IDF from Arduino IDE. However, I could not find any documentation about using ESP-ADF from Arduino.

I download firmware to ESP32-LyraTD-MSC with make flash in Ubuntu, It prompts error:
A fatal error occurred: Failed to connect to ESP32: Invalid head of packet ('\x08')
Please give me some suggestion

未改程序，使用 LyraT官方开发板，破音, 采样率貌似也不对。

可能是什么问题引起？

Anyone have pipeline_sdcard_mp3_control example works properly on latest update?
I tried the example, it worked well (before adding google translate function, I think).
After update the repository, touching SET touch pad just make the pipeline stop. I have to touch SET pad 2 times for playing next song.

Hello,

I would like to add an equalizer on audio output in ADF framework. In short i need access to data or embed equalizer functionality into pipeline as an element.

How do i do that. I have gone through documentation and the code but is clear as mud.

Thank you.
