Several questions related to modifying pipelines and keeping bluetooth connected.

I am running a pipeline that outputs audio from spiffs to a wav decoder to a bluetooth speaker. I want to keep the bluetooth speaker connection open for a long time, and when I am ready, send new sounds to the speaker. There might be long periods of time in which no sound is sent to the speaker. How...

Re: Can't get WAV to play to bluetooth speaker please help

I've tried again with a wav file that I made sure is a clean WAV file. I have attached it to this post - as a .doc file because this forum does not accept .wav files - so you must rename it to .wav. I have provided the code again below and also the output log file. Here is how I checked the wav file...

Re: Request - software MP3 decoder for ADF

Hi Jason

Are you saying the ADF currently does software-only mp3 decoding?

I had thought it required an extra audio chip to be attached - is this incorrect?

Where can I find documentation on how to do software only mp3 decoding?

thanks!

Could you please provide an example of playing WAV from spiffs to bluetooth speaker?

I've spent days trying to make this work and I just can't.

It would be a huge help if you could please provide an example showing how to play a WAV file to a bluetooth speaker from SPIFFS please?

Ideally the example would play WAV files with different bit rates and different sample rates.

thanks .

Is it *required* to have Lyra hardware?

Is it *required* to have Lyra hardware to use the ADF, or can the ADF be used with only an ESP32?

Request - software MP3 decoder for ADF

Hello

it would be extremely useful if the ADF included a software MP3 decoder.

Is this planned to be coming?

thanks!
