i have looked over and over in the examples and even here for a solution

i can play a mp3 just fine using this code:
https://github.com/pschatzmann/arduino-audio-tools/blob/main/examples/examples-stream/streams-sd_mp3-i2s/streams-sd_mp3-i2s.ino

and a wav file works but i cant seem to get them both to work at same time.

here is my code:

it will still compile and work with these warnings

I assume you are compiling in Arduino!

I don't recommend to change any settings in the preferences if you don't know what you are doing.
Did you try to change the setting for compiler warnings back to Default or None ?

ps. your logic is completely wrong: one way to correct this is to remove the copy() from the loop and add a copier.copyAll() at the end of your play methods to process the complere file.

Another is to call playwav() only after you completeley processed the first file (when the copy in the loop returns 0)

I don't quite understand you question: If you want to play multiple streams you can use the CatStream class

i got the loop working with the google ttS and happy with that. thanks!! i have another question about that and will post the code in case someone else can use it. but in another thread

but the 1st (original) question was just having both a wav and a mp3 decoder and i could use either if needed. they normally dont go in the start i just did a minimal sketch so they ended up there. the plan is to have a button press

blue button (pin21) --> will play my speech2text( ) function  --> which will play a file @ located --> /recordings/speech2text.wav
red button (pin18)--> will play my text2speech( ) function  -->  which will play a file @ located --> /recordings/ text2speech.mp3

so 2 different functions but 2 different media type files

hope that helps my explanation and thanks a ton for your responses

Did you read the Wiki: the chapter Internative Audio should put you on the right track.

There is already a google tts example in the examples-tts

yeah i have been in there and used some info to get as far as i have thanks!

but it still doesnt help in using both a wav and a mp3 in same sketch unless i missed it, i see how to use wav and a mp3 just not both

i will go thru those examples some more and see what i can maybe piece together. you have so so many awesome examples thanks for all your work

This is straight forward: you can just combine the approach given in the wiki with what you already have developped:

Just use separate handler methods for wav and mp3 that uses the parameters given in the example.
You can pass the file name as parameter instead of the frequency of the example.
Your methods sets up the copier and the file source, so that the loop can automatically process it just with copier.copy().
