# Stream Analog Input to I2S
|
||||
|
||||
## General Description:
|
||||
|
||||
In this sketch we get the data from via the ESP32 I2S ADC and send it to I2S
|
||||
Since the ADC via I2S is using the i2s port 0, we use port 1 for the output.
|
||||
|
||||
### Analog Input:
|
||||
|
||||
| ADC | ESP32
|
||||
| --------| ---------------
|
||||
| VCC | 3.3V
|
||||
| GND | GND
|
||||
| OUT | GPIO34
|
||||
|
||||
For the input I was using a MCP6022 Microphone Sensor.
|
||||
Plaese note that the signal that we receive from the ADC needs to be adjusted so that it is oscillating around 0.
|
||||
|
||||
|
||||
|
||||
|
||||
### External DAC:
|
||||
|
||||
|
||||
For my tests I am using the 24-bit PCM5102 PCM5102A Stereo DAC Digital-to-analog Converter PLL Voice Module pHAT
|
||||
|
||||
I am just using the default pins defined by the framework. However I could change them with the help of the config object. The mute pin can be defined in the constructor of the I2SStream - by not defining anything we use the default which is GPIO23
|
||||
|
||||
DAC | ESP32
|
||||
-----|----------------
|
||||
VCC | 5V
|
||||
GND | GND
|
||||
BCK | BCK (GPIO14)
|
||||
DIN | OUT (GPIO22)
|
||||
LCK | WS (GPIO15)
|
||||
FMT | GND
|
||||
XMT | 3V (or another GPIO PIN which is set to high)
|
||||
|
||||
- DMP - De-emphasis control for 44.1kHz sampling rate(1): Off (Low) / On (High)

# I2S Analog Output Test
|
||||
|
||||
This is a simple basic test for the ESP32 __analog output__ using I2S.
|
||||
|
||||
We just send a generated sine wave and expect to hear a clean signal.
|
||||
Please note the log level should be set to Warning so that there is no disturbing output!
|
||||
|
||||
Make sure that you do not use any noisy power supply!
|
||||
|
||||
### Output Device: Earphones
|
||||
|
||||
You can also use some simple earphones
|
||||
|
||||
|
||||
|
||||
On the ESP32 the stereo output is on the Pins GPIO25 and GPIO26

### Output Device: Piezo Electric Element
|
||||
|
||||
To test the output I am using a piezo electric element

This is a simple basic test for the PWM output.
|
||||
|
||||
We just send a generated sine wave to some defined pins and expect to hear some audio signal.
|
||||
|
||||
|
||||
### Output Device: Piezo Electric Element
|
||||
|
||||
To test the output I am using a piezo electric element
|
||||
|
||||
|
||||
|
||||
You can also use some simple earphones
|
||||
|
||||
|
||||
|
||||
|
||||
It should also be possible to connect a headphone to the output pins...
|
||||
|
||||
|
||||
The pins depend on the Processor:

# Stream I2S Input to CSV Output
|
||||
|
||||
## General Description:
|
||||
|
||||
We implement a I2S source: We stream the sound input which we read in from the I2S interface and displays it on the Arduino Serial Plotter.
|
||||
|
||||
We can use any device which provides the sound data via I2S. In this case it is a 'I2S ADC Audio I2S Capture Card Module'
|
||||
Usually you do not need any master clock, but unfortunatly we need to feed this module with a master clock signal from the ESP32, if
|
||||
the ESP32 is acting as master.

||||

||||

|

|

|
||||
## Additional Comments
|
||||
|
||||
I recommend this sketch as a starting point for all I2S input. Just leave the masterclock out, because this is not needed for most input devices.
|
||||
If it is working with 32 bit you can try to change it to 16bits which most of the time works as well:
|
||||
|
||||
- CsvOutput<int16_t> csvOutput(Serial);
|
||||
- cfg.bits_per_sample = 16;

## Micro Speech
|
||||
|
||||
The staring point for doing speech recognition on an Arduino based board is TensorFlow Light For Microcontrollers with the example sketch called micro_speech!
|
||||
|
||||
I have adapted the MicroSpeech example from TensorFlow Lite to follow the philosophy of this framework. The example uses a Tensorflow model which can recognise the words 'yes' and 'no'. The output stream class is TfLiteAudioOutput. In the example I am using an ESP32 AudioKit board, but you can replace this with any type of processor with a microphone.
|
||||
Further information can be found in the [Wiki](https://github.com/pschatzmann/arduino-audio-tools/wiki/TensorFlow-Lite---MicroSpeech).
|
||||
To capture the Audio we use an INMP441 Microphone:
|
||||
|
||||
|
||||
|
||||
|
||||
The INMP441 is a high-performance, low power, digital-output, omnidirectional MEMS microphone with a bottom port. The complete INMP441 solution consists of a MEMS sensor, signal conditioning, an analog-to-digital converter, anti-aliasing filters, power management, and an industry-standard 24-bit I²S interface. The I²S interface allows the INMP441 to connect directly to digital processors, such as DSPs and microcontrollers, without the need for an audio codec in the system.
|
||||
|
||||
## Pins

||||

|
||||

|
||||
| WS | WS (GPIO15)
|
||||
| SCK | BCK (GPIO14)
|
||||
|
||||
|
||||
- SCK: Serial data clock for I²S interface
|
||||
- WS: Select serial data words for the I²S interface
|
||||
- L/R: Left / right channel selection
|
||||
When set to low, the microphone emits signals on the left channel of the I²S frame.
|
||||
When the high level is set, the microphone will send signals on the right channel.
|
||||
- ExSD: Serial data output of the I²S interface
|
||||
- VCC: input power 1.8V to 3.3V
|
||||
- GND: Power groundHigh PSR: -75 dBFS.

||||
|
||||
The log level has been set to Info to help you to identify any problems. Please change it to AudioLogger::Warning to get the best sound quality!

# Stream PDM Input to CSV Output
|
||||
|
||||
## General Description:
|
||||
|
||||
To use a PDM microphone you need to have a microcontroller that supports PDM input or a dedicated library.
|
||||
|
||||
The ESP32 supports PDM via the I2S API: We stream the sound input from a PDM microphone (PDM Digital MEMS MP34DT01) which we read in from the I2S interface and displays it on the Arduino Serial Plotter.

You can select if you receive only data on the left or right by setting SEL to high or low.
|
||||
|
||||
Please note that in the 2.x realease of the Arduino ESP core, the WS pin is used as CLK. Prior to this it was BCK

# Decoding a MP3 file
|

In this example we decode a MP3 file into RAW output and send it the analog output pins.
|
||||
|
||||
Currently we provide multiple mp3 decoders
|
||||
- libhelix
|

- tinymp3
|

Unfortunatly non of those are currently stable in all environments....

To test the output I am using piezo electric elements
|

It should also be possible to connect a headphone to the output pins.

# Decoding a MP3 file with Metadata
|
||||
|
||||
In this example we provide the ID3 metadata from a MP3 file. We support the old ID3V1 and the newer ID3V2.
|
||||
The MetaDataID3 class is used as stream output destination.
|
||||
You register your callback method with setCallback().

# Decoding a MP3 file
|
||||
|
||||
In this example we decode a MP3 file into RAW output and write the output with the help of a PWM signal to the pins.
|
||||
|
||||
Currently we provide multiple mp3 decoders
|
||||
- libhelix
|
||||
- tinymp3
|
||||
|
||||
Unfortunatly non of those are currently stable in all environments....
|
||||
|
||||
|
||||
### Output Device: Earphone
|
||||
|
||||
To test the output I am using an earphone from a mobile phone.
|
||||
We get 2 signals one for the left and the other for the right channel.
|
||||
|
||||
|
||||
|
||||
|
||||
The pins depend on the Processor:
|
||||
|
||||
|
||||
| EarPhone | ESP32 | RPI Pico | MBED |
|
||||
| -----------| -------------|---------------|--------------|
|
||||
| Left | GPI2 | GPI2 | GPI2 |
|
||||
| Right | GPI3 | GPIO3 | GPI3 |
|
||||
| GND | GND | GND | GND |
|
||||
|
||||
To verify check the PIN_PWM_START in AudioConfig.h or you can set the pins by calling setPins() method on the PWMConfig object.

# Decoding a MP3 file
|

|

In this example we decode a very short MP3 file using lebhelix
|
||||
|
||||
### External DAC:
|
||||
|
||||
|
||||
|
||||
For my tests I am using the 24-bit PCM5102 PCM5102A Stereo DAC Digital-to-analog Converter PLL Voice Module pHAT
|
||||
|
||||
I am just using the default pins defined by the framework. However I could change them with the help of the config object. The mute pin can be defined in the constructor of the I2SStream - by not defining anything we use the default which is GPIO23

# Decoding a MP3 file
|
||||
|
||||
In this example we decode a very short MP3 file using lebhelix
|
||||
|
||||
### External DAC:
|
||||
|
||||
|
||||
|
||||
For my tests I am using the 24-bit PCM5102 PCM5102A Stereo DAC Digital-to-analog Converter PLL Voice Module pHAT
|
||||
|
||||
I am just using the default pins defined by the framework. However I could change them with the help of the config object. The mute pin can be defined in the constructor of the I2SStream - by not defining anything we use the default which is GPIO23

# Digital output via I2S to a external DAC
|
||||
|
||||
Somtimes we want to store the sound file in memory. [Audacity](https://www.audacityteam.org/) might help you out here: export with the file name audio.raw as RAW signed 16 bit PCM and copy it to the SD card. In the example I was just using one channel to save memory!.
|
||||
|
||||
Then you can convert the file with xxd into a C file that contains the data in an array. In the Sketch I am using the __MemoryStream class__ which turns the array into a Stream.
|
||||
|
||||
Please note that you must compile this sketch with the __Partition Scheme: Huge App__!
|
||||
|
||||
|
||||
### External DAC:
|
||||
|
||||
|
||||
|
||||
For my tests I am using the 24-bit PCM5102 PCM5102A Stereo DAC Digital-to-analog Converter PLL Voice Module pHAT
|
||||
|
||||
I am just using the default pins defined by the framework. However I could change them with the help of the config object. The mute pin can be defined in the constructor of the I2SStream - by not defining anything we use the default which is GPIO23

# Decoding a WAV file
|
||||
|
||||
In this example we decode a WAV file into RAW output and send it to a PWM pins (on a Raspberry Pico or ESP32)
|
||||
|
||||
The WAV file has been down sampled with the help of __Audacity__ and then converted into an array with __xxd__.
|
||||
|
||||
Please note that this example is still using the more confusing old api which uses the following processing chain:
|
||||
MemoryStream -> AudioOutputStream -> WAVDecoder -> AudioPWM
|
||||
|
||||
|
||||
The pins depend on the Processor:
|
||||
|
||||
| PIEZO | ESP32 | RPI Pico | MBED |
|
||||
| --------| -------------|---------------|--------------|

# Generating Audio with Tensorflow Liete
|
||||
|
||||
The starting point is the good overview provided by [the "Hallo World" example of Tensorflow Lite](https://www.tensorflow.org/lite/microcontrollers/get_started_low_level#train_a_model) which describes how to create, train and use a model which based on the __sine function__.
|
||||
|
||||
We just send a generated sine wave to the I2S interface. Further information can be found in the [Wiki](https://github.com/pschatzmann/arduino-audio-tools/wiki/Tensorflow-Lite----Audio-Output)
|
||||
Please note the log level should be set so that there is no disturbing output!
|
||||
|
||||
|
||||
### External DAC:
|
||||
|
||||
For my tests I am using the 24-bit PCM5102 PCM5102A Stereo DAC Digital-to-analog Converter PLL Voice Module pHAT
|
||||
|
||||
|
||||
|
||||
I am just using the default pins defined by the framework. However I could change them with the help of the config object. The mute pin can be defined in the constructor of the I2SStream - by not defining anything we use the default which is GPIO23
|
||||
|
||||
|
||||
DAC | ESP32
|
||||
-----|----------------
|
||||
VCC | 5V
|
||||
GND | GND
|
||||
BCK | BCK (GPIO14)
|
||||
DIN | OUT (GPIO22)
|
||||
LCK | BCK (GPIO15)
|
||||
FMT | GND
|
||||
XMT | 3V (or another GPIO PIN which is set to high)
|
||||
|
||||
- DMP - De-emphasis control for 44.1kHz sampling rate(1): Off (Low) / On (High)
|
||||
- FLT - Filter select : Normal latency (Low) / Low latency (High)
|
||||
- SCL - System clock input (probably SCL on your board).
|
||||
- FMT - Audio format selection : I2S (Low) / Left justified (High)
|
||||
- XMT - Soft mute control(1): Soft mute (Low) / soft un-mute (High)
|
||||
|
||||
