Redirecting audio output to WAV file

[hash6iron]

Hello,

Congratulations for you excellent work with this library. I'm coding a device that play TAP and TZX files for ZX Spectrum computer using a ESP32 Audiokit module. You can know about it in my GitHub https://github.com/hash6iron/powadcr

I'd like to taka advantage the output that is generate with square waves to create a wav file in the SD to debug operations but I don't know how to do it. Could you send me an example to try it?

On the other hand. I've noticed when I change volume the stream stop, I'm generating the stream on real time , I create a wave and write it in a buffer to output. How can I change volume without sounds cut?

Thanks in advance.

I dont't quite understand your problem: just read the Wiki Documentation about Encoding and replace the NoiseGenerator with a SquareWaveGenerator.

There is a wiki about volume, but in this case you can just set the amplitude directly.

Your statement about using a buffer does not make any sense to me.

I suggest to spend some more time reading the availalble documentation which includes the wiki and class documentation

Hello, Thanks for your quick response. I have written a specific square wave generator adapted to my needed, but it's similar at some wave generator example. Then I'd like to redirect this example Sine wave generator to WAV file (instead of to speaker) I have read a lot of possible but I don't finish to understand. I appreciate your help Thanks.

Did you read the chapter about encoding ?
What part of the given file example did you not understand ?

[hash6iron]

Not I don't any doubt about the example but I don't know how to redirect for example Sine wave generated to WAV file instead of line out. Anyway I'm going to review again this chapter if you think that the information is perfectly clear. Best regards. El vie, 11 ago 2023 23:00, Phil Schatzmann ***@***.***> escribió:

But the given example does exactly what you are asking for!
It even gives you some valuable hints...

Ok. I'm going to review again. Thanks so much. BR. El vie, 11 ago 2023 23:07, Phil Schatzmann ***@***.***> escribió:

Hi Phil, Another question Is it possible to know the battery level with Audiokit (ES8388 audio processor version)? Thanks in advance. El vie, 11 ago 2023 23:50, Hash6Iron ***@***.***> escribió:
