s60sc / esp32_voicechanger Goto Github PK

Hi, wondering if I could have some pointers to getting this working? I'm using a devkit board with an INMP441 and a MAX98357A. Firstly, I have tested tested my hardware using separate scripts, one to view the mic waveform in the serial plotter, and another to play audio in the speaker, both work ok. However I can't just get the voice changer script to work. I have entered the pins correctly, tried switching the "I2S Peripheral Channel" settings, and changed the various other controls but can't get anything out of the speaker.

An example extract from the log showing that there's no errors really:

[00:09:44.805 setupMic] Setup I2S microphone
[00:09:44.817 setupAmp] Setup I2S amplifier
[00:09:44.818 startupMic] Start microphone on port 1
[00:09:44.818 startupAmp] Start amplifier on port 0
[00:09:44.830 actionTask] Passthru started
[00:10:03.103 actionTask] Passthru stopped

Any help appreciated!

it is not an issue, but a request. Do you have the schematic you used? Can you share it?

Dear @s60sc,

I trust this message finds you in good health. I have been thoroughly intrigued by your project, which I recently came across. Specifically, I was drawn to its "Pass Thru" capability, with the aspiration of emulating the distinctive sound of a storm trooper.

Regrettably, it appears that a substantial portion of the functionalities within the project are currently non-operational, with the exception of the following elements:

• Volume
• Preamp Gain
• Brightness

Moreover, any attempt to modify the value of the "Pitch Shift" parameter results in an ESP32 system crash, accompanied by the "Guru Meditation Error."

For clarity, I have thoughtfully compiled an illustrative representation of the functional status of these features. Functions deemed operational are highlighted in green, those that are non-functional are marked in red (signifying that alterations to their values yield no perceptible change in sound output), and functions displaying minimal and arguably inconsequential alterations are highlighted in yellow. You can view this graphical representation:

he hardware configuration I employed for testing includes the following components:

• ESP32 S3 (LILYGO T-Display S3)
• I2S Interface INMP441 Microphone
• MAX98357A I2S 3W Class D Amplifier
• 3W Speaker

To enhance the utility of your project, I would like to propose the incorporation of a menu system featuring predefined voice settings for popular movie characters such as Storm Troopers and Darth Vader. Additionally, granting users the ability to dynamically switch between voice modes through physical buttons and incorporating a small OLED screen for real-time mode selection display would be valuable additions.

In conclusion, I must commend you on conceiving such an intriguing project. Given its potential, once these issues are addressed, it is poised to become one of my favorite projects.

Best Regards,

If I try to load sketch in my ESP32 WROOM Devkit, I get:

Hello s60sc!
I've successfully uploaded your code to an ESP32 and connected to its network, but accessing 192.168.4.1 always shows the network configuration screen instead of the VC.htm page, using either the UI or OTA to update the settings. Do you know what could be the issue?
Thank you
(Edit: turns out the network name can't have a space, even if ALLOW_SPACES is set to true)

Hi,
Which librarie(s) do I have to install for the VoiceChanger?
I currently get an error message #include "ping/ping_sock.h" ?
Thank you

hello,
some shit , i try run with i2s mic ,but now
