Hello..can the adau 1701 be connected to amplifier after programming

Very helpful video, thank you

hello, can you share me link of this version the root 2.0?

HOW TO ADD YOUR OWN STARTUP SOUND EXAMPLE: THIS IS MY KARAOKE

The icp5 does NOT supply power to the ADAU1701 dsp. Once i connected both the dsp started working and was able to connect in sigma. Also the files on diyaudio dont work with modern x64 O/S. Version 4.6 worked fine.

Can we build sinewave inverter using this class D circuit ?

Great video!! If anyone is wondering how to enable PDM2PCM option then make sure that CRC is activated.

Excellent this is almost exactly my small project right now

Nice, do you also have a pitch change example for esp32 to be live?

ESP32 действительно мощный

Very good! …I work in STM, do you think to add also auto tune?

i just got a JAB4 modules and I am playing around. This bass boost moduls looks very interesting. Is is possible to integrate the ability the bass boost intensitiy to adjust by a potentiometer? I am a but unsure about everything. Is it possible to mess up everything by writing nonsense to the eprom and if yes, is there a way to reset to factory settings somehow?

Could you tell me which pins from the pmod should be connected to the label pins in stm?

i have ordered the pcm510 but i want to test-run the setup using just the esp32 (so using the built-in DAC instead of the pcm510). how can i do this? 😅

You are my guru boss! Thanks for the help ful video. I highly appreciate you. You are a genius 💖💖💖💖💖💖💖

This was a masterpiece project.

Thank you sir for such an advanced project.

This is the exactly the video what i was looking for. Thank you sir

Thanks sir

Very nice video, thx a lot!

I'm about to embark on a project that includes something like this setup. Just to be clear, the MCLK frequency is 44kHz * 256 = 11.2MHz, and the ESP32 is able to output a clean signal on GPIO0?

Ok

Saw now. Thanks! Running a diode ladder filter emulation on an MCU was using too much of the MCU, so pondering adding an FPGA. Maybe add a second MCU instead though.

Wow sounds super impressive! Is this realtime?

Does anyone know the maximum signal/input voltage?

Brooo, your video is exactly what I've been looking for since 4 days. I'm so glad

These two lines *must* be in error (assuming int is 32 bits). int lsample = (int) (rxBuf[0]<<16)|rxBuf[1]; int rsample = (int) (rxBuf[2]<<16)|rxBuf[3]; But rxBuf[0] and rxBuf[2] are uint16_t and your parenths surround the values **after** shifting left by 16 bits. How does that work? If the compiler was doing its job, the 16-bit unsigned integer read from rxBuf[0] would have been shifted left by 16 bits and nothing but zeros would remain in that 16-bit value. *Then* you cast it to (int), which I presume is 32 bits. How does that work? C is reasonably strongly typed and rxBuf[0]<<16 and rxBuf[2]<<16 should both be zero before you cast it to a 32-bit value. Inside the pareths there is no hint that this is a 32-bit value. Those two lines *should* be int lsample = ( (int)rxBuf[0]<<16 ) | rxBuf[1]; int rsample = ( (int)rxBuf[2]<<16 ) | rxBuf[3]; First you must cast the value rxBuf[0] into (int), *then* shift it left 16 bits. C will naturally cast the 16-bit value rxBuf[1] to 32 bits since the left operand is now 32 bits. How can this mis-casting the uint16_t possibly work? I cannot see how it can work. C is strongly typed.

Hello, thank you for this. Where can I download the circuit? Thank you very much.

Can you help me fix in building/compiling "HINT: The issue is better to resolve by replacing format specifiers to 'PRI' -family macros (include <inttypes.h> header file)."

Nice!

nice video. but i m having problem. the 4 potentiometer are not working

Thanks so much for your generousity Sir

Well done and Great explanation

Great, thanks that you also fixed that AVRCP issue!

Thank you, great presentation. For anyone who struggles as much as I do importing models in LT spice, I suggest substituting something like the ADuM4221, already in the library, for that TI gate driver.

Can you take Bluetooth audio input and broadcast through wifi to other ESP for sync audio speakers as multi room speaker anyone have answer please reply.

Are you using the internal DAC of the ESP32?

Can I only use the esp32 part with the codes in it but use different amplifier board, I only need the dsp 4 channel processing part of the esp32 and can you tell me how if its okay with you? Many thanks in advance. Great video btw.

Grazie per l'ottima spiegazione ..... (Thanks a lot for your helpful video)

Hello could you please show the wiring connection between the stm32 and pmod? I have been trying to get this to work but I think my wires are off

thanks

Hi! Hows the sound quality?

Nice video! I would recommend doing filter processing in the main loop though.

Excellent tutorial! Liked & subscribed. Is there a online forum that is good for SigmaStudio support for more complex projects. For example, I'd like to use an ADAU1701 DSP will several amplifiers, which are also have ADAU1701 DSPs. It would be great to see a tutorial on connected multiple DSPs together, with both analog and digital inputs. For example, I plan to merge AptX HD stereo signal with analog stereo signal, then equalize, apply active bass, then crossovers to multiple amps. I also want to add pots for main volume, individual amp volumes, bass, mid, treble, and analog input.

This was a very good video, I would recommend a part-2 there are other aspects not covered or mentioned that needs to address subject, propagation delay and control theory.

Dear sir, Pls let me know Wiring diagram: esp32 + PCM5102, thanks.

Hi, I know this video is 3 years old now but if theres any chance you or anyone would anwser if it is possible to change the master clock of I2S while its running to get a sort of bit-crunch effect. I know reducing the sample size can be done but I'm interested if it is also possible to change the bitrate and have it controlled via a potentiometer. Thank you.

I am using ESP32 Wrom-32 and want to use internal dac, but during idf.py build, i givin the next error "ninja: build stopped: subcommand failed. HINT: The issue is better to resolve by replacing format specifiers to 'PRI'-family macros (include <inttypes.h> header file). ninja failed with exit code 1, output of the command is in the C:\Espressif\frameworks\esp-idf-v5.2\examples\bluetooth\bluedroid\classic_bt\a2dp_sink\build\log\idf_py_stderr_output_8312 and C:\Espressif\frameworks\esp-idf-v5.2\examples\bluetooth\bluedroid\classic_bt\a2dp_sink\build\log\idf_py_stdout_output_8312 PS C:\Espressif\frameworks\esp-idf-v5.2\examples\bluetooth\bluedroid\classic_bt\a2dp_sink>" can you help give me some point hot to resolve prtoblems>?

You are great. Thank you.
