Can 2 speakers be connected to the same converter module? Or should I use another module for another speaker?

[@nehajain2974]

Thank you for the video, plz make video to stream an music url from internet using esp32 internal dac

[@Shadoweee]

Can the output of the MAX module be used as input for an AMP that normally uses audio jack as input?

[@evelinkalil5422]

this could work in a xiao esp32s3?

[@sahyeeshnubatumalai7430]

Can i play a youtube video in that? Can i use my phone as mic and sound came out from speaker?

[@thebloody_blue]

I think you must add audio.h in your library .

[@claudiomiranda2]

Would it be possible to add a display to view the audio information? such as name, progress, folder etc...

[@afyu]

I saw a library where you can extract metadata from a file

[@dedenapraia]

Great Video !, thank you very much !. Do you know how loud (Decibels) can the MAX98357 be ? I am looking forward to tun my ESP32 into an audio receiver

[@afyu]

Did not find any information like that

[@dedenapraia]

@@afyu thank you for the reply :) . But at least is loud enough to have indoor music right ?

[@afyu]

yes, the volume is enough for comfortable listening in the room

[@thexht7927]

The loudness depends on the speaker not the chip. Good speaker can make louder audio with the same power. But expect something max 95dB (very good speaker) or below, talking about speaker having about 3W power rating

[@nicolassacristanmosquera9109]

Why don't you use one of the two DACs that have the esp32?

[@saifialeem8255]

Maybe for the Inbuilt amplifier, otherwise that's my guess.

[@lamngoc9896]

Can you make speaker with esp32 and es8388 ?

[@afyu]

the board must support the I2S protocol

[@lamngoc9896]

@@afyu yes

[@gadget_vishwa]

Does we get true stereo output?

[@afyu]

To get a stereo output, you need to use two such modules or pay attention to the PCM5102.

[@gadget_vishwa]

@@afyu how can use two modules.... To get stereo output with one connectivity Bluetooth device (mobile,pc)
