[FREE]WaveAudioTools extension v3

This extensions let you mix or combine 2 wave audiofiles in different ways:
Now you can create karaoke-like-apps, mix tracks together or combine them, create long wavefiles from short loops (e.g. drumtracks) as a backline.
** min API21 required **

  • added “Trim” method to let you cut a wavefile

**Important:**The files must be of same format, 16Bit/44100/stereo or 16Bit/44100/mono wave format. You will notice a slight "click or “swoop” at the seams of the combined files. Maybe one day I will manage to smooth that.
(Maybe someone like to assist me here)

Please show your blocks (rightclick in the blockeditor, “Download Blocks as Image”).
Tip: Write in your native language and use a translator.

I tested it in Kodular, and you are right: “MixWav” isn’t working! Only “LoopWav” and “CombineWav” are working.
I also tested it on AppInventor, and there all is working as it should.
I took my own example aia from here:

Edit: I found the solution: set MinSDK to API 21 in “advanced Properties”

oh oke, thank you. I’ll try it
